Easy Lentil Taco Soup with black beans! A family-friendly meal that everyone can load up with their own favorite taco toppings. (Vegan, gluten-free, oil-free)

This Lentil Taco Soup is super easy to assemble, yet incredibly flavorful (and so pretty!) I’m continually looking for more ways to work in lentils. They’re inexpensive and packed with awesome nutrients. This simple soup is one of my favorites, plus I love that it’s another use for my homemade taco seasoning blend. A quick & easy way to infuse those delicious fiesta-style flavors!

The best part is you can load it up with all your favorite taco toppings before serving. It’s a fun, family-friendly meal that works great for kids & crowds – just double the recipe if needed for more. (We also enjoy some of these same flavors in the Mexican Quinoa Stuffed Peppers.) Hope you love it as much as we do!

I made this today and it was AMAZING. I had a can of cooked lentils already, so I used those instead of uncooked. Worked fine and cut down on cooking time! 35 minutes including clean-up!
10/10 recipe that will be added to my arsenal of quick, taste and healthy dinners!

My husband and I are huge lentil fans. We rated this recipe a 10 out of 10! My husband is not fond of cumin so I reduced the taco seasoning to 2 tablespoons followed the rest of the recipe to a T garnished with the tomatoes cucumber cilantro and then a dollop of sour cream on top the perfect meal.

Good morning! Could this recipe be made in a Crock-Pot? I really want to try this recipe, but it’s my 1st time cooking with lentils. We are working on switching to a plant based diet. Thanks
Hi! I haven’t tried that yet, but I think it’d make a wonderful crock-pot meal! Would love to hear if you give it a go π Hope you have a beautiful week! -Kaitlin
I am “UNFORTUNATELY ” in a Extended Stay Hotel, can I make in a Slow Cooker?? I am “EXCITED” to try your recipes!! Thank You!!
Hi there! I haven’t tried this recipe in a slow cooker, but I suspect it would do quite well! Would love to hear if you give it a go π And thanks for the kind words – thrilled to hear you’re excited about the recipes! Hope you enjoy any you try! Have a lovely week!
Great recipe! I used two 10 oz cans of rotel instead of diced tomatoes and added in 2 sliced corn tortillas prior to cooking for 30 minutes. I also used vegan chicken better than bouillon and ended up adding in another cup of broth at the end. Turned out great! Spicy but thatβs how we like it at my house. I topped with lime juice, crushed tortilla chips and a dollop of sour cream. Will definitely be making again!
Hi Jessica! Woo!! So fantastic to hear that & I love your adaptions π Thanks for giving it a try and coming back to leave such a sweet comment (and recipe rating!) Very appreciated! Stay safe & well <3
My family of six π loved π this recipe! We added the cayenne pepper which gave it some heat but not to spicy! Lentils… so delicious. We also added 1 can of rotel with a 1/2 cut tomato. Green pepper and pinto beans with the black beans and corn. I added about 4 more cups of vegetable broth. Then garnished with tomato, avocado and cilantro! π Thank you for sharing this recipe for those of GF and vegetarian!
