Notes for the Best Vegetarian Lentil Chili
- If you prefer a thicker chili, remove the lid during the last 30 minutes of cooking.
- For an extra boost of flavor, sauté onion, garlic, and spices in olive oil before adding to the slow cooker. Learn more here.
- Use green or brown lentils for the best texture—they hold up better than red lentils when slow-cooked.
