Preheat the Instant Pot on sauté mode until hot. Add oil, then ground turkey. Break it up, then let it cook without stirring until browned, 3–4 minutes.
Stir in onion, jalapeño, garlic, chili powder, 1 tsp salt, and black pepper. Cook, stirring, until onions are softened, about 6 minutes.
Add Liquid and Beans
Stir in the water or broth, black beans, kidney beans, and remaining 2 tsp salt. Scrape the bottom of the pot thoroughly until it feels totally smooth.
Layer Tomatoes
Pour in diced tomatoes with their juices and the tomato paste. Do not stir them in.
Pressure Cook
Lock the lid and set valve to Sealing. Pressure Cook on High for 12–15 minutes. Let pressure release naturally for 10 minutes, then quick release. Stir and taste. Adjust seasoning before serving.
Notes
Chicken broth: If using chicken broth instead of water, reduce the salt to 2 tsp then adjust at the end. Burn Prevention: Keeping tomatoes and tomato paste on top avoids scorching. Deglaze the pot fully after sautéing. Trivet + Parchment Option: For total burn-proof cooking, sauté in a Dutch oven, then set up the Instant Pot with 1 cup water, a trivet, and parchment barrier. Add chili on top and pressure cook as directed. Storage: Refrigerate up to 4 days or freeze up to 3 months. Reheat gently with a splash of water if thick.
