These crispy baked tacos start with a classic ground beef filling, folded into tortillas with cheese and baked until golden and crispy. The upgrade? A can’t-taste-it swap that boosts the protein and fiber even further: red lentils, cooked right in the same pan as the beef, no extra pot and no pre-cooking required. They melt right into the meat as everything simmers, so the flavor and texture stay exactly the same — just with more staying power in every bite.
If you need proof that this recipe works on even the pickiest audience, here it is: I made a batch of these for dinner and my teenage son gobbled them up without a single question about what was in them. That’s the real test in my house, and these passed with flying colors! As a nutritionist, I love developing recipes that pass the taste test and are loaded with nutrients.
Why You’ll Love This Recipe
- Sneaky extra protein and fiber — the lentils blend right into the ground meat, so you get the nutritional upgrade without anyone clocking it
- One pan for the filling — the lentils cook directly in the meat mixture, no separate pot to wash
- Genuinely crispy — baked, not fried, but still golden and crunchy thanks to a few key details (more on that below)
- Kid-tested — my teenage son gobbled these up without asking why they were different than his typical taco night!
Ingredient Notes
- Red lentils, not brown or green. This matters more than it sounds like it should. Red lentils cook fast, about 15 minutes, and break down into the meat as they cook, which is exactly what you want here. Brown or green lentils take much longer and hold their shape, so they won’t work the same way in this recipe.
- Fire-roasted tomatoes add a subtle smokiness that plain diced tomatoes don’t.
- Ground turkey or beef both work well here, use whichever your family prefers!
- Apple cider vinegar is a key ingredient because it gives this recipe its acid and tang!
- Flour tortillas are preferred because they hold their shape better than corn. However, you can use corn tortillas, just make sure you heat them beforehand!
- Monterey jack cheese or sharp cheddar is recommended.
How to Make Crispy Tacos
- Cook the ground beef, then add taco seasoning, fire roasted tomatoes, and apple cider vinegar.
- After giving this a quick stir, add the lentils, and water or broth. Bump up the heat to a boil, then simmer for 10 – 12 minutes.
- While the taco meat is cooking, preheat your oven to 425 degrees F.
- After the meat mixture is cooked, spoon it into each tortilla, and top with cheese. Fold and brush each side with oil.
- Bake for 12 – 15 minutes, flipping the tacos halfway through. Use an eye test, and pull out the tacos when the tortillas are golden.
How to Serve and Store
These are great on their own with the usual taco toppings: a squeeze of lime, some diced avocado or guacamole, a dollop of Greek yogurt or sour cream, fresh cilantro, and a simple corn salad or cabbage slaw on the side. They also hold up well for meal prep; reheat in the oven or air fryer for a few minutes to bring back the crispiness rather than microwaving, which will soften the shell. They were also added to my son’s lunchbox this week!
Store leftovers in an airtight container in the fridge for up to 3-4 days. Reheat in a 375°F oven or air fryer for 5-8 minutes to re-crisp. Microwaving works in a pinch but will leave the shell soft.
High Protein, High Fiber Crispy Baked Tacos with Ground Beef
Ingredients
- 1 lb lean ground beef
- 3 tsp chili powder
- 1.5 tsp ground cumin
- 1 tsp paprika
- 1 tsp garlic powder
- 1 tsp kosher salt
- 1 14.5oz can fire-roasted diced tomatoes
- 2 tsp apple cider vinegar
- 2/3 cup dry red lentils, (uncooked)
- 1.5 cups chicken or beef broth, (or water)
- 8 medium flour tortillas
- 1.5 cups shredded monterey jack or cheddar cheese
- 2 tbsp olive oil or avocado oil
Instructions
- Preheat the oven to 425 degrees F.
- Brown the ground beef over medium high heat, contiuing to break up the meat as it cookes. Drain excess fat, keep the pan hot.
- Meanwhile, stir the taco seasoning ingredients: chili powder, cumin, paprika, garlic powder, and sea salt. Pour on top of the meat, adding in apple cider vinegar and the can of tomatoes. Give the mixture a quick stir.
- Now stir in the lentils and broth. Increase the heat to high, or until the mixture comes to a rolling boil. Reduce the heat to low and a gentle simmer. Let the lentils soak up the moisture and cook for about 12-15 minutes. Add salt to taste if needed, then remove from heat.
- Assemble the tacos by filling each tortilla with a scoop of the beef/lentil mixture, and a few tbsp of cheese. Fold the tacos in half and lightly brush oil on both sides of the exterior of the taco. Place on a lightly greased sheet pan, or sheet pan covered in parchment paper.
- Bake until crispy, about 15 minutes, flipping when baking is halfway. The tacos are done when they are golden brown and crisp on both sides.
- Let cool slightly before serving with your favorite taco toppings.
