Ingredients
- 1 large yellow onion (approximately 150 grams), finely chopped
- 3 cloves garlic (approximately 15 grams), minced
- 2 medium sweet potatoes (approximately 600 grams), peeled and chopped into 2.5 cm (1 inch) cubes
- 2 cans (796 milliliters / 28 ounces each) diced tomatoes, undrained
- 1 can (398 milliliters / 14 ounces) red kidney beans, drained and thoroughly rinsed
- 225 grams (1 ½ cups) frozen corn kernels
- 840 milliliters (3 ½ cups) vegetable broth (for slow cooker method)
- 300 grams (1 ½ cups) dried green lentils, rinsed
- 2 tablespoons (30 grams) chili powder
- 2 teaspoons (10 grams) ground cumin
- Salt to taste
- Freshly ground black pepper to taste
- 1 large avocado, diced, for garnish (optional)
- Fresh parsley or cilantro, chopped, for garnish (optional)
Instructions
- Begin by preparing your vegetables. Finely chop the yellow onion, mince the garlic, and peel then cube the sweet potatoes into uniform 2.5 cm (1 inch) pieces. Rinsing the dried green lentils thoroughly before use is crucial as it removes any debris and helps prevent excess foaming during cooking.
- For the slow cooker method, carefully combine all the prepared ingredients into your slow cooker pot. This includes the chopped onion, minced garlic, cubed sweet potatoes, both cans of diced tomatoes (do not drain them), the drained and thoroughly rinsed red kidney beans, frozen corn, 840 milliliters (3 ½ cups) of vegetable broth, the rinsed green lentils, chili powder, and ground cumin.
- Using a large spoon, stir all the ingredients together vigorously. Ensure that the spices are evenly distributed throughout the mixture and that all components are well combined, which promotes consistent flavor development during the long cooking process.
- Securely place the lid onto your slow cooker. Cook the chili on the "Low" setting for 8 hours or, if you're short on time, on the "High" setting for 4.5 hours. Cooking on a lower heat for a longer duration allows the flavors to meld more deeply and the lentils to become perfectly tender.
- Once the cooking time is complete, carefully remove the lid. Taste the chili and season generously with salt and freshly ground black pepper according to your preference. If you desire a more pronounced chili flavor or increased heat, add additional chili powder, 1 teaspoon at a time, tasting after each addition until your desired spice level is achieved.
- For the Instant Pot or Pressure Cooker method (designed for a 6-quart/5.7-liter pot), make a crucial adjustment: reduce the amount of vegetable broth to 720 milliliters (3 cups). This reduction is essential to prevent a potential "Burn" error and to ensure the chili achieves the correct consistency, as less liquid evaporates in a pressure cooker.
- Add all the ingredients for the Instant Pot method – including the chopped onion, minced garlic, cubed sweet potatoes, diced tomatoes, drained and rinsed kidney beans, frozen corn, 720 milliliters (3 cups) of vegetable broth, rinsed green lentils, chili powder, and ground cumin – into the Instant Pot insert. Stir everything thoroughly to ensure proper mixing.
- Place the lid onto the Instant Pot and twist it to the locked position. Verify that the pressure release valve is set to the "Sealing" position. Select the "Pressure Cook" or "Manual" setting and set the cooking time for 10 minutes on high pressure. Be aware that the pot will take approximately 30 minutes to build up to full pressure before the cooking time begins.
- After the pressure cooking cycle has finished, press the "Cancel" button and allow the Instant Pot to naturally release pressure for 15 minutes. This natural release process is beneficial as it helps to prevent foaming from the lentils and allows the chili to settle and thicken properly.
- Once the 15-minute natural release period has elapsed, carefully move the pressure release valve from "Sealing" to "Venting" to quick release any remaining pressure. Ensure you stand clear of the steam that will escape.
- When the float valve pin has completely dropped back down, which indicates all internal pressure has been released, you can slowly unlock and safely remove the lid. Always open the lid away from your face to avoid residual steam.
- Regardless of the cooking method, taste the chili and adjust the seasoning. Add salt and freshly ground black pepper to your preference. If you desire more heat or a stronger chili flavor, incorporate additional chili powder, 1 teaspoon at a time, until the chili meets your taste expectations.
- Thirteenth Step: Serve the hearty chili hot. Optionally, garnish each serving with freshly diced avocado for a creamy texture and healthy fats, and a sprinkle of fresh parsley or cilantro for a burst of vibrant color and freshness.
Tools You’ll Need
- Slow cooker (at least 5.7 liters / 6 quarts) OR Instant Pot / Pressure Cooker (6 quarts)
- Large cutting board
- Sharp chef's knife
- Measuring cups and spoons
- Can opener
- Large stirring spoon or ladle
Essential Success Tips
- Rinse lentils thoroughly before adding them to remove any dust or debris, which can also significantly help in preventing excessive foam during the cooking process.
- Chop sweet potatoes into uniform 2.5 cm (1 inch) cubes for even cooking. Irregularly sized pieces might result in some becoming mushy while others remain undercooked.
- Always perform a final seasoning check at the end of cooking; chili flavors deepen and evolve, so adjusting salt, pepper, and chili powder to taste is crucial for perfect results.
- For a thicker chili, you can carefully mash a small portion of the cooked sweet potatoes against the side of the pot with a spoon or simmer the chili uncovered for a short period after cooking.
- If utilizing an Instant Pot, strictly adhere to the reduced broth amount specified (3 cups) to prevent a "Burn" error and ensure your chili achieves the ideal, hearty consistency.
Professional Cooking Secrets
- To significantly deepen the foundational flavor profile, take an extra step to sauté the chopped onion and minced garlic in a tablespoon of olive oil in a skillet (or directly in the Instant Pot on Sauté mode) until softened and fragrant before adding the remaining ingredients. This caramelizes the aromatics and creates a richer base.
- Introduce a wonderful smoky complexity by incorporating a teaspoon of smoked paprika along with the chili powder and cumin. For those who enjoy more heat, a pinch of cayenne pepper or a finely chopped deseeded jalapeño can be added at the beginning of cooking.
- For an umami boost that rounds out the savory notes, stir in a tablespoon of tomato paste when sautéing aromatics, or a teaspoon of tamari (gluten-free soy sauce) during the final seasoning step. This subtle addition enhances the overall depth without altering the chili's core character.
Notes
- Storage: Leftover chili is a fantastic meal prep option. Store it in an airtight container in the refrigerator for up to 5 days. This chili also freezes exceptionally well for up to 3 months; thaw overnight in the refrigerator before reheating gently on the stovetop or in the microwave.
- Variations: Feel empowered to customize this chili with additional vegetables such as diced bell peppers, zucchini, or fresh spinach during the last 30 minutes of cooking. For an even heartier meal, stir in cooked quinoa or brown rice at the end.
- Serving Suggestions: This chili is wonderfully satisfying on its own, but it also pairs beautifully with a dollop of dairy-free sour cream, a sprinkle of nutritional yeast for a cheesy essence, or served alongside warm cornbread or crispy tortilla chips.
Frequently Asked Questions
Can I use a different type of lentil for this chili?
While green lentils are highly recommended for this chili due to their ability to hold their shape well and provide excellent texture, you could substitute them with brown lentils. Red lentils tend to break down much more during cooking, which might result in a thicker or slightly mushier chili, but the flavor would still be delicious.
Is it possible to make this chili spicier?
Absolutely! To increase the heat, you have a few options. You can add a finely chopped jalapeño or serrano pepper along with the onion and garlic at the beginning. Alternatively, stir in a pinch of cayenne pepper or a dash of your favorite hot sauce during the final seasoning step, adjusting to your preferred level of spice.
Can I prepare this recipe ahead of time for meal prep?
Yes, this chili is an outstanding candidate for meal preparation! In fact, many people find that the flavors meld and deepen even further after a day or two, making it taste even better. Simply cook the chili as directed, allow it to cool completely, then store it in airtight containers in the refrigerator for up to 5 days or freeze individual portions for convenient future meals.
