How to make this healthy tacos recipe
Our lentil tacos recipe is one of our favorite go to recipes, and it’s become a fan favorite. We took our old recipe and gave it a new spin as healthy tacos with grilled vegetables. In this version, I got lazy and didn’t want to make the entire taco seasoning batch, so I threw all the spices in with the lentils. It may seem like a lot of spices, but you’ll likely find many of them in your spice drawer (if not, they’re good ones to have around!).
For the grilled vegetables, they’re very easy to make. Simply slice red onion, zucchini, and summer squash into thin strips, drizzle them with olive oil and season with kosher salt and black pepper. Then toss them on the grill and cook at medium heat for about 5 minutes, until tender. They’ll come off the grill a bit charred and with a smoky flavor, perfect for tacos!
These healthy tacos may take a bit of time to put together, but they’re worth it! To save time, you could make the lentils in advance. And make sure to make up the pickled onions in advance (they’re easy to put together!).

Description
This grilled vegetable healthy tacos recipe features charred zucchini and onion, taco-spiced lentils, and a creamy sauce to tie it all together.
Ingredients
For the lentils
- 1 ¼ cups brown lentils (8 ounces)
- 1 tablespoon olive oil
- 2 tablespoons ketchup
- 1 tablespoon chili powder
- ½ tablespoon ground cumin
- ½ teaspoon each paprika, garlic powder, onion powder, and oregano
- ½ teaspoon kosher salt
- ½ teaspoon black pepper
- 1 pinch crushed red pepper flakes (or more, depending on your spice tolerance)
For the grilled vegetables
- 1 summer squash
- 1 zucchini
- 1 onion
- Olive oil
- Kosher salt
- Pepper
For the tacos toppings
- Tortillas (make your own, or purchase them)
- Pickled red onions
- Chili lime sour cream, Cashew cream, Chipotle sauce, or Creamy cilantro sauce
Instructions
- Preheat a grill to medium heat.
- In a medium saucepan, bring 1 ¾ cups water to a boil (and add a pinch of kosher salt). Once boiling, add the brown lentils, cover and reduce heat. Simmer covered for 20 to 25 minutes, until most of the water has been absorbed.
- Turn off the heat, then stir in the olive oil, ketchup, chili powder, cumin, paprika, garlic powder, onion powder, dried oregano, kosher salt, black pepper, and red pepper flakes.
- Meanwhile, cut the squash, zucchini and onion into thin strips. Place them in a bowl; toss with enough olive oil to coat, and sprinkle with kosher salt and pepper. Grill the vegetables until tender, for about 5 minutes, turning frequently.
- Make the pickled red onions and the sauce of your choosing (Chili lime sour cream, Cashew cream, Chipotle sauce, or Creamy cilantro sauce).
- To serve, add lentils to a warmed tortilla; top with grilled vegetables, pickled onions, and chili lime sour cream.

I’m still learning the grill but these look amazing! I love your other version of lentil tacos but adding grilled veggies to it sounds even better. Can’t wait to try this and hopefully not fail with the grilled veggies!
I love lentils and tacos so much! Your lentil tacos look fantastic, I’ll have to give them a try soon. Glad your site is back up and thank you for the link love!

These definitely look worthy of those homemade corn tortillas!

Love this blog!!!
Greetings from Belgium.
I love tacos as well, I made tacos from a black bean and jicama salad last night. I have yet to try using lentils, it sounds amazing though!
Yum!! This looks so delicious! I might try it with a combination of black beans and quinoa instead of lentils, since my husband refuses to eat them! But wow – I might have to make it just for myself!
I usually do these with half a bottle of beer instead of ketchup, you get that
nice yeasty flavor without all the added sugar.
viva mexico !
Clever! We’ll have to try it.
