Prep the aromatics and vegetables: peel and finely dice the onion, core and dice the bell pepper, and mince the garlic. Uniform cuts ensure even cooking and a smooth texture in the finished chili.

Heat a heavy-bottomed pot or Dutch oven over medium heat and add the olive oil. When the oil shimmers (about 30–45 seconds), add the diced onion and a pinch of salt. Sauté 6–8 minutes until the onion is translucent and beginning to caramelize. Sweating the onion slowly develops natural sweetness and builds the flavor base for the chili.

Add the diced bell pepper and continue to cook another 4–5 minutes until softened. Then add the minced garlic and cook 30–45 seconds until fragrant. Adding garlic later prevents it from burning and turning bitter.

Stir in the tomato paste and toast it with the vegetables for 60–90 seconds. Toasting tomato paste deepens its flavor by concentrating its sugars and adds an umami backbone to the chili.

Lower the heat slightly and add the chili powder, ground cumin, smoked paprika, dried oregano and cayenne (if using). Stir constantly for 30 seconds to bloom the spices in the fat — this releases the essential oils and makes the chili aromatic and flavorful.

Pour in the canned tomatoes (crush any large pieces with your spoon) and the vegetable broth. Scrape the browned bits off the bottom of the pot — those fond bits are concentrated flavor. Bring the mixture to a gentle simmer.

Add the three cooked beans to the pot and stir to combine. Add salt and black pepper. Simmer uncovered on low for 20–25 minutes, stirring occasionally, until the chili thickens and the flavors meld. A gentle simmer reduces excess liquid and allows the beans to absorb the spiced tomato broth.

Taste and adjust seasoning: balance salt, heat, and acidity. If the chili tastes too bright/tomato-forward, add a small pinch (1/4 tsp) of brown sugar or a splash of olive oil to round it out. If it needs more body, simmer 5–10 minutes longer to concentrate flavors.

To serve: Spoon 1/2 cup cooked brown rice into each bowl (about 3/8 cup per serving if you prefer mixing — recipe yields 1.5 cups rice for 4 servings so plan accordingly), ladle the chili over the rice, and finish with a drizzle of olive oil or a squeeze of lime if desired. Serving over rice makes this a hearty, complete meal and keeps the rice fluffy under the hot chili.

Leftovers: chili thickens as it cools. To reheat, add a splash of water or broth and warm gently on the stove so the texture loosens and the flavor reactivates.
