Ingredients Breakdown and Why They Work
🌱 Lentils
Green or brown lentils are best since they hold their shape. They bring an earthy base and lots of fiber.
🫘 Black Beans
Creamy, hearty, and full of protein. Using canned black beans saves time, while dried beans (soaked overnight) offer a firmer bite.
🍅 Crushed Tomatoes
A tangy backbone that balances the smokiness of the spices. Tomatoes also provide natural umami.
🫑 Vegetables
Onions, bell peppers, garlic, and jalapeño form a bold aromatic base. Each vegetable contributes its own texture and depth.
🌽 Corn
Sweet pops of flavor that balance the savory spices and add color.
🥣 Vegetable Broth
Keeps it vegan and enhances the chili’s body without needing meat stock.
🌶️ Spices
- Chili powder: the foundation of warmth.
- Cumin: earthy depth.
- Oregano: Mediterranean flair.
- Smoked paprika: campfire-style smokiness.
🌿 Fresh Cilantro
Stirred in at the end, it brightens everything with freshness.
Pro Tips for Success
- Always rinse lentils – This removes grit and ensures clean flavor.
- Use a 6-quart slow cooker – Prevents overflow while allowing space for stirring.
- Chop vegetables uniformly – Even cooking makes for better texture.
- Spice layering – Toast spices in a small skillet for 1–2 minutes before adding; it intensifies flavor.
- Taste at the end – Chili flavors bloom over time; adjust salt, lime juice, or spice just before serving.
