Vitamin B3, or niacin, rarely gets the spotlight it deserves. While folate and vitamin B12 dominate the nutritional conversation, niacin quietly powers over 400 enzymatic reactions in the human body, from converting macronutrients into usable ATP energy to synthesising and repairing DNA strands. A chronic shortfall leads to fatigue, brain fog, and in severe cases pellagra, a deficiency disease that was tragically common before nutritional science caught up. This Turkey and Avocado Bowl is built specifically to flood your system with B3 in the most delicious way possible.
The centrepiece is lean ground turkey, one of the single richest dietary sources of niacin on the planet, delivering roughly 8 to 10 mg per 100 g cooked. Layered on a base of nutty farro (which contributes its own modest B3 hit alongside impressive fibre and manganese), topped with roasted sweet potato for beta-carotene and potassium, and finished with half an avocado per serving for heart-healthy monounsaturated fats and folate, this bowl is a complete nutritional architecture, not just a collection of healthy ingredients thrown together. A bright cumin-lime dressing ties everything together and adds a fat-soluble delivery vehicle that maximises absorption of the carotenoids in the sweet potato.
One of the things we love most about this recipe at Calibrated Cuisine is its versatility. You can build the turkey component on the stovetop in under 30 minutes, hand it off to a slow cooker on a busy workday, or pressure-cook it to a deeply flavourful result in a fraction of the time. No matter which method you choose, the bowl assembly is the same, and the nutritional payoff is identical. Every serving clocks in at approximately 640 calories with 45 g of protein and enough niacin to cover 80% of the daily recommended intake for an adult.

Instructions
🔧 Equipment
- Cook the farro: Bring a large pot of salted water (at least 1.5 litres) to a rolling boil. Add the rinsed farro and cook uncovered for 25 to 30 minutes until tender but still pleasantly chewy. Drain through a fine-mesh sieve, toss with 1 teaspoon of olive oil to prevent clumping, and set aside covered.
- Roast the sweet potato: While the farro cooks, heat 1 tablespoon of olive oil in a large non-stick or cast-iron skillet over medium-high heat. Add the sweet potato cubes in a single layer, season with salt, pepper, and the smoked paprika. Cook undisturbed for 4 minutes until a golden crust forms on the underside, then toss and cook a further 4 to 5 minutes until tender and caramelised at the edges. Transfer to a plate and keep warm.
- Build the turkey base: In the same skillet, heat another tablespoon of olive oil over medium-high heat. Add the diced onion with a pinch of salt and cook for 3 to 4 minutes, stirring occasionally, until softened and translucent. Add the garlic, cumin, chilli flakes, and oregano and cook for 60 seconds until intensely fragrant, stirring constantly to prevent the garlic from scorching.
- Brown and simmer the turkey: Add the ground turkey to the skillet, breaking it apart with a wooden spoon or heat-proof spatula. Cook for 5 to 6 minutes over medium-high heat until no pink remains and some pieces have developed a light golden-brown crust for added flavour and texture. Add the diced red bell pepper and cherry tomatoes, then pour in the chicken broth. Stir to combine, reduce heat to medium-low, and simmer uncovered for 8 to 10 minutes until the liquid reduces by about two-thirds and the mixture is glossy and cohesive. Season assertively with salt and pepper.
- Make the cumin-lime dressing: In a small bowl, whisk together the remaining 1 tablespoon of olive oil, fresh lime juice, a pinch of cumin, a pinch of salt, and half the chopped coriander. Taste and adjust seasoning.
- Assemble the bowls: Divide the cooked farro among four wide bowls. Spoon the turkey mixture generously over the farro, then arrange the roasted sweet potato cubes alongside. Fan the sliced avocado over the top. Drizzle the cumin-lime dressing over everything, scatter the remaining coriander and toasted pumpkin seeds, and serve immediately.
- Sear the turkey for depth of flavour: Although optional, this step adds a significant flavour dimension. Heat 1 tablespoon of olive oil in a skillet over medium-high heat. Add the ground turkey and cook for 4 to 5 minutes, breaking it up, just until the exterior is no longer pink. Do not cook through completely. Transfer the par-cooked turkey to the slow cooker insert. If you prefer to skip this step for convenience, add the raw turkey directly to the insert.
- Layer the slow cooker: Directly into the slow cooker insert on top of the turkey, add the diced onion, minced garlic, red bell pepper, cherry tomatoes, cumin, smoked paprika, chilli flakes, and oregano. Pour in the full 400 ml of chicken broth. Stir everything together until the spices are evenly distributed. Season with salt and pepper, then add the sweet potato cubes on top (they stay firmer when layered above the liquid rather than submerged).
- Low and slow cook: Secure the lid and cook on Low for 6 to 8 hours or on High for 3 to 4 hours. Avoid lifting the lid during cooking, as each peek extends cook time by 15 to 20 minutes. The turkey will be completely tender, the sweet potato will be soft, and the liquid will have reduced into a rich, aromatic sauce.
- Cook the farro: About 35 minutes before serving, bring a large pot of salted water to a boil and cook the farro for 25 to 30 minutes until tender. Drain and toss with 1 teaspoon of olive oil.
- Finish and assemble: Once the slow cooker cycle is complete, stir the mixture gently, taste, and adjust seasoning with additional salt, pepper, and a squeeze of lime juice directly into the slow cooker. Whisk together the cumin-lime dressing as in the stovetop method. Divide farro among bowls, ladle the turkey and sweet potato mixture over the top, then lay the sliced avocado alongside. Drizzle with dressing, finish with coriander and toasted pumpkin seeds, and serve.
- Saute aromatics: Set your Instant Pot or pressure cooker to Saute mode on High. Add 2 tablespoons of olive oil and heat until shimmering. Add the diced onion and cook for 3 minutes, stirring frequently. Add the garlic, cumin, smoked paprika, chilli flakes, and oregano and stir for 45 seconds until the spices bloom and become very fragrant.
- Brown the turkey: Add the ground turkey directly to the pot. Break it apart with a wooden spoon and cook on Saute mode for 3 to 4 minutes until the exterior is mostly cooked. Stir in the red bell pepper and cherry tomatoes. Press Cancel to stop the saute function.
- Add remaining ingredients and pressure cook: Add the sweet potato cubes, then pour in 300 ml of the chicken broth (reduce from 400 ml as no evaporation occurs under pressure). Stir briefly and season with salt and pepper. Secure the lid, set the pressure valve to Sealing, and cook on Manual High Pressure for 8 minutes.
- Quick release and reduce: When the timer sounds, carefully perform a quick pressure release by turning the valve to Venting. Once all steam has escaped and the float valve drops, open the lid. The mixture will look quite liquid. Switch back to Saute mode on Normal and simmer uncovered for 3 to 5 minutes, stirring occasionally, until the sauce reduces to your preferred consistency.
- Cook the farro concurrently: While the pressure cooker does its work, cook the farro separately in a large pot of boiling salted water for 25 to 30 minutes, drain, and toss with 1 teaspoon of olive oil. Timing these together means everything finishes within minutes of each other.
- Assemble: Make the cumin-lime dressing. Divide farro among four bowls, top with the turkey and sweet potato mixture, arrange sliced avocado over the top, drizzle with dressing, scatter coriander and toasted pumpkin seeds, and serve immediately.
- Preheat and prepare: Position two oven racks in the upper-middle and lower-middle positions. Preheat the oven to 200 C (400 F) fan-assisted or 220 C conventional. Line two large rimmed baking sheets with parchment paper.
- Season and roast the sweet potato: On the first baking sheet, toss the sweet potato cubes with 1 tablespoon of olive oil, smoked paprika, salt, and pepper until evenly coated. Spread in a single layer with space between cubes to encourage roasting rather than steaming. Place on the lower rack.
- Prepare the turkey sheet pan: In a large bowl, combine the ground turkey with the diced onion, minced garlic, red bell pepper, cherry tomatoes, cumin, chilli flakes, oregano, 1 tablespoon of olive oil, 3 tablespoons of the chicken broth (just enough to keep the mixture moist), salt, and pepper. Mix thoroughly with your hands or a spatula until the spices are evenly distributed. Spread the turkey mixture in a rough, crumbly single layer on the second prepared baking sheet. It does not need to be uniform. Place on the upper rack.
- Roast both trays: Roast for 20 minutes undisturbed. At the 20-minute mark, remove both trays from the oven. Flip the sweet potato cubes, and use a spatula to break up and toss the turkey crumble so the wetter interior pieces are exposed to the oven heat. Return both trays and roast for a further 10 to 15 minutes until the turkey has some lightly crispy edges and the sweet potato is golden and tender.
- Cook the farro concurrently: While both trays roast, cook the farro in a large pot of boiling salted water for 25 to 30 minutes. Drain and toss with 1 teaspoon of olive oil.
- Assemble: Whisk together the cumin-lime dressing. Divide the farro among four bowls. Top with the crispy turkey crumble and roasted sweet potato. Fan the sliced avocado on top. Drizzle generously with the lime dressing, scatter fresh coriander and toasted pumpkin seeds, and serve while everything is still hot.

The Nutrition Science
Niacin (vitamin B3) exists in two primary dietary forms: nicotinic acid and nicotinamide, both of which are converted in the body to the coenzymes NAD (nicotinamide adenine dinucleotide) and NADP. These coenzymes are indispensable to cellular respiration, acting as electron carriers in the glycolysis, citric acid cycle, and oxidative phosphorylation pathways that generate the ATP your cells run on. Without adequate NAD, mitochondria cannot efficiently convert glucose, fatty acids, or amino acids into energy, which is precisely why niacin deficiency manifests first as profound fatigue and cognitive slowdown. Ground turkey is exceptional here because its high tryptophan content (207% RDA per serving in this recipe) provides an additional biosynthetic route to NAD: the body converts approximately 60 mg of tryptophan into 1 mg of niacin via the kynurenine pathway, effectively giving this bowl a niacin equivalent that exceeds its direct niacin content alone.
The combination of turkey with farro is nutritionally deliberate. Farro is an ancient whole grain that contributes manganese (83% DV per serving), a cofactor for the enzyme superoxide dismutase, one of the body’s primary antioxidant defence proteins. It also provides a slower-digesting carbohydrate source than refined grains, keeping postprandial blood glucose more stable. The beta-glucan and arabinoxylan fibres in farro have been shown in multiple randomised controlled trials to modestly reduce LDL cholesterol, complementing the favourable lipid effects of avocado’s oleic acid and the selenium in turkey, which supports the antioxidant enzyme glutathione peroxidase.
The fat profile of this bowl deserves specific attention. Each serving provides roughly 15 g of monounsaturated fat, primarily from avocado and olive oil. This is not merely a cardiac benefit. The fat-soluble carotenoids in sweet potato and cherry tomatoes, including beta-carotene (7.2 mg per serving) and lycopene (3.1 mg), require dietary fat present in the same meal for optimal micellar absorption in the small intestine. A 2005 study in the Journal of Nutrition demonstrated that adding avocado to a tomato-based salsa increased lycopene absorption by 4.4-fold and beta-carotene absorption by 2.6-fold compared to a fat-free version. This bowl replicates exactly that synergy, making the nutrient density greater than the sum of its individual ingredients.
Pro Tips
- For maximum niacin yield, use dark meat ground turkey (85% lean) instead of 93% lean. Dark meat contains slightly more B3, B6, zinc, and iron than white meat, and the added fat keeps the mixture moist across all cooking methods without significantly changing the calorie count.
- Toast the pumpkin seeds in a dry skillet over medium heat for 2 to 3 minutes until they begin to pop and turn golden. This activates Maillard compounds, deepens the nutty flavour, and makes the seeds far more aromatic as a topping.
- Avocado should be added cold and sliced directly before serving to prevent browning. If you are meal-prepping this bowl, store the turkey mixture, farro, and sweet potato together but keep the avocado separate, tossed with a little lime juice and stored cut-side-down in an airtight container for up to 24 hours.
This is exactly the kind of recipe I’ve been looking for, honestly. My last quarterly labs showed my homocysteine was still creeping up despite being pretty consistent with my protocol, and my functional medicine doc mentioned niacin status could be a factor in that metabolic pathway. A couple questions though: are you sourcing the turkey from pasture-raised operations, and do you know the niacin content difference between ground versus whole cuts? I’m also curious whether the cooking method affects bioavailability here, since I’ve read that high heat can impact B vitamin retention. Already planning to make this next week.
Log in or register to replyFred, glad you’re tracking this with labs – that’s the clinical approach that actually moves the needle. Quick thought from the ICU side: niacin’s homocysteine work is real, but it doesn’t operate in a vacuum. Make sure you’re also solid on folate and B12 status (get them checked if you haven’t recently), because those three work together on methylation. Turkey’s your niacin source here, which is good, but the avocado and sweet potato round out the micronutrient picture nicely. One bowl won’t solve elevated homocysteine, but this as part of a consistent pattern with your doc’s oversight should show movement in your next labs – keep us posted
Log in or register to replyLove that you’re tracking this with your doctor, Fred! Niacin is such a game-changer for homocysteine metabolism, and I’m curious if you’ve considered pairing this bowl with other B-complex rich foods throughout your week. Turkey is solid for sure, but I’ve found that adding things like black-eyed peas or even a sprinkle of nutritional yeast can layer in more B vitamins without much extra effort. Plus, the combination of niacin with folate and B6 works synergistically for that homocysteine support your body needs.
