Ingredient Notes

  • Diced Tomatoes: Any brand of diced tomatoes. I like fire-roasted diced tomatoes.
  • Onion: I usually use white or yellow onion but red onion is also fine.
  • Spices: The blend of spices includes chili powder, cumin, paprika and oregano. I like to use smoked paprika for a smoky flavor. For spicy chili, you can add up to 1 tsp cayenne pepper or red pepper flakes. Note the recipe does already contain jalapeno but it’s not overly spicy as long as you remove the seeds.
  • Bell Peppers: You can use green bell pepper, red bell pepper or any other colour. I like to mix and match different colors for variety.
  • Red Lentils: This recipe is for red lentils though you can substitute brown or green lentils, just note it will have a different texture as red lentils are soft when cooked and green/brown stay firm and retain their shape .
  • Vegetable Broth: Any store-bought or homemade broth, bouillon base or vegetable stock works.
  • Tomato Paste: Tomato paste helps deepen the tomato flavor but if you’re in a pinch, you can substitute any tomato sauce.

The complete list of ingredients with measurements is located in the recipe card below.

Additions & Variations

  • Toppings: Avocado, tortilla chips, chilantro, sour cream, cheddar cheese, green onions, lime juice, salsa.
  • Beans: Mix in 1 or 2 cans of beans such as chickpeas, black beans, kidney beans or pinto beans for additional texture.
  • Sweet Potatoes: Sweet potato works well in this recipe. Add up to 2 cups peeled and cubed sweet potato.
  • Serving: Serve with a toasted and butter bun or any bread for dipping.

    This is an outstanding recipe! I cooked it on high for 6 hours, & everything was tender. My husband & I loved it. Heโ€™s even taking some to work today for himself & for a friend to try. Thank you!

    Amazing taste, packed full of healthy goodness, super quick and easy to make! Slow cooked for 6 hours.ย

    I made this in the slow cooker, but my carrots were crunchy and the lentils were still firm. I’m not sure that 3 hours was enough (on high, used 4 cups of broth). Maybe I’ll try cooking another hour and hope it helps. Otherwise it’s takeout for dinner tonight!

    This was so delicious! I did it stove top. Cashew cream and avocado are musts as toppings. My belly can’t handle that many lentils, so I swapped one cup of the lentils for a 4 oz package of chopped baby spinach that I added at the end of cooking. Thank you!

    This was a super easy recipe. It smelled great while it was cooking. I put it over some leftover rice I had in the fridge and it was delish.

    Man, this is good! Unfortunately, I evidently used old lentils. They kind of donโ€™t cook right. But Iโ€™m eating it anyway.ย

    This looks really good. Do you have an adaption for the Instant Pot? I imagine it would be easy enough to do.

    1. I do red lentils for 9 min. So I’d saute the veggies then add everything else and do high pressure for 9 min then quick release. I haven’t tried it though!

    I love this recipe! Itโ€™s super easy, delicious AND high in protein. Itโ€™s one of the first recipes I made after going plant-based and even my husband, who isnโ€™t plant-based, loved it!ย
