High Protein Crockpot Lentil Taco Chili

This high protein crockpot lentil taco chili is the weeknight dinner that basically cooks itself while you live your life. Packed with green lentils, black beans, and bold taco spices, it comes together in a slow cooker with almost zero effort. I made this for the first time on a super chaotic Monday, and when I walked in to that smell after a long day, I knew I’d be making it on repeat.

There’s something about chili that just feels like a hug in a bowl. This one hits all the right notes: smoky, a little spicy, hearty, and genuinely satisfying. The lentils and black beans load it up with plant-based protein, and the taco-inspired seasoning keeps it anything but boring. I love that I can dump everything in, walk away, and come back to something that tastes like it simmered all day on the stove because it did.

Ingredients for High Protein Crockpot Lentil Taco Chili

For the Chili:

• 1 cup dry green lentils (rinsed twice under cold water)
• 2 cans (15 oz each) black beans (drained and rinsed well, I recommend low-sodium)
• 1 medium onion (diced into 1/2-inch pieces)
• 1 red bell pepper (diced into 1/2-inch pieces)
• 1 green bell pepper (diced into 1/2-inch pieces)
• 3 cloves garlic (minced)
• 1 jalapeno pepper (minced, seeds removed for less heat, leave them in if you like it spicy)
• 1 can (28 oz) crushed tomatoes
• 3 cups vegetable broth (pro tip: a richer broth means more depth of flavor)
• 1 cup salsa (your preferred heat level, chunky works best)
• 2 cups frozen corn
• 1 1/2 tbsp ground cumin
• 2 tbsp chili powder
• 1 tsp dried oregano
• 1/2 tsp smoked paprika
• Salt and black pepper to taste
• 2 tbsp fresh cilantro, chopped (added at the very end)
• Juice of 1/2 lime (added at the very end, in my experience fresh lime makes all the difference)

For the Pico de Gallo:

• 2 cups roma tomatoes (diced into 1/4-inch pieces)
• 1 cup white onion (finely diced)
• 1 jalapeno pepper (minced, seeds removed for milder flavor)
• 1/4 cup fresh cilantro (finely chopped)
• Juice of 1/2 lime
• 3/4 tsp salt

Optional Toppings:

• Sliced avocado
• Sour cream
• Grated cheese
• Crushed tortilla chips
• Sliced jalapeno peppers
• Fresh cilantro

Step-by-Step Instructions

Step 1: Rinse the dry green lentils under cold water using a colander, rinsing twice to remove any debris. Dice the onion and bell peppers into 1/2-inch pieces. Mince the garlic and jalapeno. Drain and rinse the black beans thoroughly.

Step 2: Add the diced onion, minced garlic, and jalapeno to the slow cooker. Pour in the vegetable broth and crushed tomatoes. Add the cumin, chili powder, oregano, and smoked paprika. Stir well so the spices distribute evenly through the liquid. Adding spices directly to the broth helps them bloom properly and prevents any bitter concentrated spots.

Step 3: Add the rinsed lentils, diced bell peppers, black beans, salsa, and frozen corn. Stir thoroughly to combine, making sure the lentils are fully submerged in the liquid. This is important for even cooking.

Step 4: Cover and cook on HIGH for 5 hours or on LOW for 9 to 10 hours, until the lentils are completely tender and the flavors have melded together. If you can, give the chili one stir about halfway through to keep things cooking evenly and prevent anything from sticking to the bottom.

Step 5: While the chili cooks, make the pico de gallo. Combine diced roma tomatoes, white onion, jalapeno, cilantro, lime juice, and salt in a bowl. Stir to combine and refrigerate for at least 30 minutes before serving so the flavors have time to come together.

Step 6: Once cooking is complete, taste and season with salt and black pepper. Stir in the lime juice and fold in the fresh cilantro just before serving. Adding both at the very end preserves their brightness and freshness.

Step 7: Ladle into bowls and top with fresh pico de gallo along with any additional toppings you love.

What to Serve with High Protein Crockpot Lentil Taco Chili

This chili is a full meal on its own, but the right side dish can take it to the next level. Here are my favorite ways to round out the bowl.

Steamed Rice: Serving this chili over a scoop of fluffy white or brown rice soaks up all that rich, smoky sauce and adds even more staying power to an already filling meal. If you love rice bowls, my Taco Rice Bowl with Black Beans and Avocado uses a similar flavor profile and would give you great inspiration for toppings.

Warm Tortillas: Use the chili as a hearty burrito or taco filling. Spoon it into a warm flour tortilla with avocado and a little sour cream. My Black Bean Taquitos are another great plant-based option to serve alongside if you want to stretch the meal further.

Crushed Tortilla Chips: Pile them right on top for crunch. The contrast of crispy chips against the thick, hearty chili is genuinely addictive.

A Simple Green Salad: A crisp romaine salad with lime vinaigrette balances the bold, smoky flavors and adds a fresh cooling element to the meal. For something heartier and packed with protein, my Roasted Veggie Chickpea Bowls make a great plant-based side or companion dish.

Sliced Avocado: The creamy richness of avocado plays perfectly against the heat and acidity of this chili while adding healthy fats that keep you satisfied longer. For a full avocado-forward meal alongside, try my Buffalo Chickpea Salad Wraps for an easy plant-based pairing.

Sweet Potato Lentil Shepherd’s Pie: If you are already loving lentils, my Sweet Potato Lentil Shepherd’s Pie is another cozy, protein-rich plant-based dinner that uses a lot of the same pantry staples and is perfect for meal prep nights.

Tex-Mex Quinoa Salad: For a lighter, grain-based side that echoes the taco flavors in this chili, my Tex-Mex Quinoa Salad brings fresh veggie crunch and a zesty lime dressing that pairs beautifully.

Storage and Serving Tips

This high protein crockpot lentil taco chili was practically made for meal prep. Store leftovers in an airtight container in the refrigerator for up to 5 days. For longer storage, portion it into freezer-safe containers and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.

When reheating, the chili will have thickened up quite a bit as it sits. I recommend adding a splash of vegetable broth and warming it gently on the stovetop over medium heat, stirring occasionally. The microwave works well too; just cover loosely and heat in 90-second intervals, stirring between each one.

Pro tip: always store the pico de gallo separately in the refrigerator for up to 2 days. Add the fresh cilantro and lime juice to each bowl at serving time to keep the flavors as bright and fresh as possible.

Notes

Use dry green lentils only. Pre-cooked lentils will become mushy during the long cook time. Always add cilantro and lime juice at the very end to preserve freshness. The chili thickens as it sits; add a splash of vegetable broth when reheating to loosen it up. Make the pico de gallo at least 30 minutes ahead for best flavor.
