Sauté the aromatics: Set the pressure cooker to Sauté (Normal).
Add oil. Cook onion and bell pepper for 3–4 minutes until softened. Stir in garlic and cook 30 seconds until fragrant.
Bloom the spices: Add chili powder, cumin, smoked paprika, oregano, and chipotle or cayenne if using.
Stir for 30–45 seconds to bloom the spices. This wakes up the flavor.
Build the base: Stir in tomato paste and cook 1 minute. Add sweet potatoes, black beans, diced tomatoes, broth, salt, pepper, and maple syrup if using.
Mix well, scraping up any browned bits from the bottom.
Pressure cook: Seal the lid. Cook on High Pressure for 8 minutes. For softer sweet potatoes, go up to 10 minutes.
Release pressure: Let it naturally release for 5 minutes, then quick release the rest.
Open carefully.
Finish and adjust: Stir in lime juice. If the chili is thicker than you like, add a splash of broth. If it’s too thin, switch to Sauté and simmer 3–5 minutes to reduce.
Taste and season: Add more salt, pepper, or lime as needed.
For extra heat, stir in a pinch of chipotle powder or hot sauce.
Serve: Ladle into bowls and top with cilantro, avocado, cheese or dairy-free yogurt, jalapeño, and tortilla chips if you like.
