Few dishes in the world achieve the kind of primal satisfaction that a properly made khachapuri delivers. Originating from the Adjara region of Georgia, this open-faced cheese bread is shaped like a boat, filled with a molten blend of sulguni and feta cheeses, and finished tableside with a whole cracked egg, a knob of butter, and a swirl of black pepper. It is simultaneously a bread, a sauce, a cheese dish, and a vehicle for one of the most nutrient-dense combinations of calcium and protein you can eat at a single sitting. At Calibrated Cuisine, we take the authentic recipe seriously and let the ingredients do the nutritional work, because khachapuri does not need improvement, only understanding.
The bone-building credentials of this dish are extraordinary. A single serving delivers approximately 540mg of calcium, largely from the combined action of sulguni, feta, and the whole egg, alongside a phosphorus and vitamin D matrix that dramatically improves calcium absorption and incorporation into bone mineral. The high-quality complete proteins from dairy and egg supply all nine essential amino acids, including leucine at levels that actively stimulate muscle protein synthesis, which is inseparable from skeletal health. Bone is a living tissue requiring constant muscular tension and protein scaffolding, and khachapuri provides both the mineral substrate and the anabolic signal to build it.
We have calibrated this recipe so the dough uses a combination of bread flour and a small amount of whole wheat flour for added magnesium and B vitamins, while the cheese filling balances sodium by leaning on fresh feta’s brightness rather than processed alternatives. Three cooking methods are included because khachapuri is genuinely versatile: the traditional oven bake gives you the authentic charred crust and runny egg, the stovetop skillet method produces a crispier base for those without a hot oven, and the pressure cooker version offers a surprisingly steamed-tender interior that works beautifully for meal prep. Each method yields a different but equally rewarding result.

Instructions
🔧 Equipment
- Make the dough: In a large mixing bowl, whisk together the bread flour, whole wheat flour, instant yeast, salt, and sugar. Create a well in the center and pour in the warm water and olive oil. Mix with a wooden spoon until a shaggy dough forms, then turn out onto a lightly floured surface and knead vigorously for 8 to 10 minutes until the dough is smooth, elastic, and springs back when poked. Form into a ball, place in a lightly oiled bowl, cover with a damp kitchen towel, and allow to rise at room temperature for 30 minutes. The dough should puff noticeably but does not need to double for the stovetop method.
- Prepare the cheese filling: While the dough rises, combine the grated sulguni, crumbled feta, and ricotta in a bowl. Mix thoroughly with a fork until well blended. Taste and adjust salt carefully as feta is already salty. Beat the two egg yolks with the milk to create an egg wash and set aside.
- Divide and shape: Once the dough has rested, punch it down and divide into 4 equal portions (approximately 160g each). On a lightly floured surface, roll each portion into an oval roughly 24cm long and 14cm wide. Fold the long edges up and pinch the ends tightly together to form a boat shape. Press the dough sides up to create a wall at least 2cm high to contain the filling. Place one quarter of the cheese filling (approximately 150g) into each dough boat and press it into an even layer. Brush the exposed dough edges with egg wash.
- Cook the first side: Heat a 12-inch cast iron or heavy non-stick skillet over medium heat for 2 minutes. Add no oil; the cheese and egg wash will provide enough fat. Carefully slide one cheese-filled khachapuri into the dry skillet, filling side up. Cover the pan tightly with a lid or a large baking sheet acting as a lid. Cook for 5 to 6 minutes until the dough bottom is deep golden-brown and the cheese filling has melted and is bubbling. Resist the urge to lift the lid before 4 minutes as the trapped steam is what cooks the cheese thoroughly.
- Add the egg and finish: Remove the lid. Using the back of a spoon, create a small well in the center of the melted cheese. Crack one whole egg directly into the well. Drop 2 to 3 small cubes of butter around the egg. Replace the lid and cook for a further 2 to 3 minutes until the egg white is just set but the yolk remains runny. Remove from the skillet, season with cracked black pepper and a pinch of flaked sea salt, garnish with fresh dill if using, and serve immediately. Repeat with remaining khachapuri. Serve with the edge crust used to scoop and stir the molten filling.
- Make and rest the dough: Combine bread flour, whole wheat flour, instant yeast, salt, and sugar in a large bowl. Add the warm water and olive oil and mix to a shaggy dough. Knead on a floured surface for 8 to 10 minutes until smooth and elastic. Place in an oiled bowl, cover tightly with plastic wrap, and allow to rise in a warm spot for 45 minutes to 1 hour until roughly doubled in size. The longer, fuller rise builds better flavor and a more extensible dough for shaping.
- Preheat the oven aggressively: At least 30 minutes before baking, place a baking stone or a heavy rimmed baking sheet on the center rack. Preheat the oven to 230 degrees C (450 degrees F) with the fan on if available. The higher the oven temperature and the hotter the surface, the better the oven spring and crust color. Line a standard baking sheet with parchment paper for assembling the khachapuri before transferring.
- Prepare the filling and shape: Mix sulguni, feta, and ricotta together. Beat the two egg yolks with the milk for egg wash. Punch down the risen dough and divide into 4 equal pieces. On a floured surface, roll each into an elongated oval about 26cm by 15cm. Roll the long sides inward to form a raised wall, then pinch both ends together into sharp pointed boat tips. The walls should be at least 2.5cm high and well-pinched to prevent collapse during baking. Transfer two shaped boats to the parchment-lined baking sheet. Divide the cheese filling between them and press flat. Brush all exposed dough with egg wash. Repeat with the remaining two.
- Bake the dough and melt the cheese: Carefully slide the parchment sheet (with two khachapuri on it) onto the preheated stone or hot baking sheet in the oven. Bake for 10 to 12 minutes until the dough is puffed, golden-brown on the edges, and the cheese is fully melted, bubbly, and beginning to take on golden patches. The direct contact with the hot surface ensures the base cooks through without becoming soggy.
- Add egg and butter for the final bake: Remove the pan from the oven. Working quickly, use the back of a spoon to press a shallow well in the center of each cheese filling. Crack one egg into each well and scatter 2 to 3 small butter cubes around the egg yolk. Return to the oven immediately and bake for 3 to 5 minutes more, just until the egg white turns opaque but the yolk still jiggles when the pan is gently shaken. This is non-negotiable for the authentic experience: a fully cooked yolk loses the silky, sauce-like quality that makes khachapuri iconic.
- Serve immediately: Remove from the oven, grind black pepper generously over the egg and cheese, scatter fresh dill if using, and bring to the table at once. Instruct diners to tear the pointed ends of the bread, dip them into the center, and stir the egg into the melted cheese to create a flowing, golden sauce. Serve no more than 2 minutes after coming out of the oven for optimal texture.
- Make the dough: Prepare the dough exactly as in the oven method, with the full 45 to 60 minute rise time. A well-proofed dough holds up better in the moist slow cooker environment and will not taste raw in the center. While the dough rises, cut a piece of parchment paper to fit the base and sides of your slow cooker with a 3 to 4cm overhang (this acts as a sling for lifting the finished bread out). Lightly grease both the parchment and the exposed slow cooker walls above it with neutral oil.
- Prepare a large format filling: Because the slow cooker works best with a single large khachapuri rather than four small individual boats, combine the entire batch of sulguni, feta, and ricotta into one filling bowl and mix well. This recipe will make one large oval bread for 4 people, sliced at the table, which suits the slow cooker’s oval shape perfectly. Beat the two egg yolks with milk for egg wash.
- Shape and load the slow cooker: Punch down the risen dough and on a well-floured surface, roll it into a large oval just slightly smaller than the interior of your slow cooker (typically about 28cm by 18cm for a 6-quart oval cooker). Carefully lower the dough into the parchment-lined slow cooker, pressing it gently to fit the base. Fold the edges of the dough upward to form raised sides at least 2.5cm high, pinching the two pointed ends together as you would for individual boats. Spread the entire cheese filling inside the dough walls and press flat. Brush the exposed dough edges thoroughly with egg wash. The egg wash helps the dough color even without dry heat.
- Cook low and slow: Place two sheets of folded paper towel under the slow cooker lid. This is critical: paper towels absorb condensation that would otherwise drip onto the bread and make the top surface soggy. Cook on High for 2 hours. Do not lift the lid before the 90-minute mark. After 2 hours, check the dough by pressing the edge lightly; it should feel firm and springy, not raw and sticky. The cheese will be fully melted and bubbling. If the center of the dough still seems doughy, cook for an additional 15 minutes.
- Finish the egg under the broiler: Preheat your oven broiler to high. Use the parchment sling to carefully lift the khachapuri out of the slow cooker and onto a broiler-safe baking sheet. Press a wide well into the center of the cheese filling and crack all four eggs into it (or crack one egg per quadrant if you prefer). Scatter the butter cubes over the filling. Place under the broiler 15cm from the element for 2 to 3 minutes, watching constantly, until the egg whites are just set and the dough edges have taken on some golden color. Season with black pepper and serve directly from the baking sheet, cutting into quarters at the table.
- Make a quicker dough: For the pressure cooker, a shorter rise of just 20 to 25 minutes at room temperature is sufficient because the moist, high-pressure environment will complete the leavening during cooking. Combine all dough ingredients and knead for 8 minutes until smooth. Cover with plastic wrap and rest for 20 minutes while you prepare the filling and the pot.
- Prepare the pot: Pour 1 cup (240ml) of water into the bottom of the Instant Pot insert. Cut a sheet of parchment paper to fit the base of a 7-inch round cake pan or a 7-inch springform pan that fits inside your pressure cooker (use the PIP, or pot-in-pot, method). Grease the pan and parchment well with butter. Because of the round pan constraint, this method makes one round khachapuri-style bread rather than the traditional boat shape; the flavor and nutrition are identical.
- Shape and fill for PIP cooking: On a lightly floured surface, divide the dough in half. Roll one half into a circle slightly larger than your pan. Press it into the base and up the sides of the prepared pan, forming a dough cup with walls about 2cm high. Combine all the cheeses and spread the filling evenly into the dough cup, leaving a 1cm border at the top so the filling does not bubble over. Roll the second dough half into a circle the same size as the pan and lay it over the top as a lid, pressing the edges to the walls to seal. Brush the top with egg wash. Using a skewer, pierce 4 small steam vents in the dough lid.
- Pressure cook: Place the trivet into the Instant Pot over the water. Set the filled pan on the trivet. Seal the lid and set the valve to Sealing. Cook on Manual High Pressure for 25 minutes. Allow a full natural pressure release for 10 minutes, then carefully switch the valve to Venting to release remaining pressure. Open the lid, lift the pan out using silicone mitts, and test the dough by pressing: it should be cooked through and spring back firmly.
- Broil to finish with egg: Preheat the broiler to high. Run a knife around the edge of the pan and invert the bread onto a broiler-safe baking sheet; then flip it right-side up. Using a sharp knife, cut an oval window in the top dough lid, removing the center crust to expose the molten cheese filling beneath (this recreates the open-boat aesthetic). Press a well into the cheese with a spoon and crack all four eggs into the opening. Scatter butter cubes over. Broil 15cm from the element for 2 to 3 minutes until egg whites are just set. Crack black pepper over the top, garnish with dill, and serve immediately cut into wedges.

The Nutrition Science
The bone-building synergy in khachapuri is not accidental: it arises from the biological relationship between calcium, phosphorus, and protein. Bone mineral is primarily hydroxyapatite, a crystalline lattice of calcium and phosphorus ions, but that mineral is embedded in a collagen scaffold that is roughly 30% of bone’s dry weight. Collagen synthesis requires adequate protein intake, specifically the amino acids glycine, proline, and lysine, the last of which khachapuri supplies at 110% of RDA from the combined dairy and egg proteins. Without sufficient lysine, hydroxylation of collagen precursors is impaired and the scaffold weakens regardless of how much calcium is consumed. This dish provides both the mineral and the scaffold protein simultaneously.
The calcium in this recipe comes predominantly from sulguni and feta, two cheeses with high bioavailability because the fermentation and acid environment in these cheeses partially pre-digests casein proteins, reducing their calcium-binding affinity and making the mineral more freely available in the gut. Dairy calcium has an absorption fraction of approximately 30 to 35%, roughly twice that of most plant sources, and the presence of dietary fat from the egg yolk and butter further enhances absorption by stimulating bile acid secretion, which in turn activates vitamin D-dependent calcium transport channels in the duodenum. The phosphorus content (38% DV) is critical here because calcium and phosphorus must be deposited together into hydroxyapatite; a high-calcium, low-phosphorus diet paradoxically increases urinary calcium excretion rather than retention.
The riboflavin, vitamin B12, selenium, and iodine profile of this dish is a direct reflection of its dairy and egg base. These four nutrients are among the most difficult to obtain at therapeutic levels from plant foods alone. Selenium at 76% DV is particularly notable: as a cofactor for selenoprotein P and glutathione peroxidase, selenium reduces oxidative stress in osteoblasts (bone-building cells), and observational data consistently show that populations with low selenium status have higher rates of osteoporosis. The iodine contribution (59% DV) is equally important for anyone with thyroid function concerns, since thyroid hormones directly regulate the rate of bone remodeling through osteoclast activity. Khachapuri is therefore not merely a calcium delivery system but a comprehensive bone-matrix support food.
Pro Tips
- If sulguni is unavailable, a 50/50 blend of low-moisture mozzarella and halloumi is the most accurate substitute: mozzarella provides the melt while halloumi contributes sulguni’s characteristic mild brine and springy texture.
- Salt the filling conservatively before tasting because feta cheese saltiness varies significantly between brands; a filling that tastes slightly under-salted raw will taste perfectly seasoned once the egg and butter are added.
- For a crispier bottom crust on the stovetop version, preheat a thin film of clarified butter in the skillet before adding the khachapuri: clarified butter has a higher smoke point than whole butter and produces superior browning without burning.
ooh the calcium content is amazing but im also wondering – have you thought about fermentation for this?? i know it sounds wild but ive been experimenting with long fermented cheese breads and the fermentation actually increases bioavailability of minerals plus the probiotics are incredible for gut health which influences bone density too! even just doing a slower rise with a really active starter could boost the whole nutritional profile. plus pete makes a great point about complexity, and i think the microbiome angle gets overlooked in bone health conversations so much
Log in or register to replyI love where you’re both going with this, especially Kirsten’s point about the microbiome angle! That said, I’d flag that traditional khachapuri cheeses (especially the aged ones) and long fermented starters can be pretty high in histamine, which might be something to note for readers like me with mast cell issues. The good news is that a slower, cooler fermentation actually produces fewer histamines than warm/fast ones, and using fresher cheeses like quark or ricotta instead of aged varieties keeps the histamine load way down while still hitting that bioavailability win you’re talking about. The mineral absorption benefit from fermentation is real, but timing and temperature matter more
Log in or register to replyThis is a delicious dish, no question, but I’d gently push back on the bone density angle here. Calcium is definitely important, and 50% DV per serving is genuinely impressive, but bone health is way more complex than just mineral load – you’ve also got phosphorus ratios, vitamin K2 (which fermented dairy does contain!), and the actual mechanical stress from exercise doing the heavy lifting. That said, the protein content is the real MVP here for bone turnover, and I love that you’re highlighting a traditional food that naturally checks multiple boxes. Have you tested whether the fermentation or cooking method affects the bioavailability of those minerals, or is this straight nutritional analysis from the
