Why This Recipe Works (Quick Science)
The slow cooker gives the spices plenty of time to spread through the liquid and beans. As the chili cooks, the tomatoes break down and combine with the vegetable broth to create a richer flavor. The beans absorb some of the seasoned liquid, making every bite taste better. Slow cooking also helps the vegetables become tender without turning mushy.
Pro Tips
- Drain and rinse the beans well to keep the chili from tasting too salty.
- Dice the onion and bell pepper into small pieces so they cook evenly.
- If you like thicker chili, remove the lid during the last 30 minutes of cooking.
- Add the cilantro right before serving for the freshest flavor.
- Let the chili sit for 10 minutes after cooking to help the flavors settle.
