Walnut Lentil Baked Taco ingredients

Walnuts add a hearty, nutty flavor and a little extra crunch to the filling. They’re the secret ingredient that gives these tacos their signature savory texture.
Lentils form the base of this flavorful taco filling. I love using canned lentils here because they make this recipe come together fast with minimal prep.
Onions and garlic help build the flavor of the filling. I prefer red onions, but other types work too.
Bell pepper brings a pop of color to the mix. Green is my go-to, but feel free to swap in red, orange, or yellow instead.
Tortillas hold all the cheesy walnut-lentil goodness together and get perfectly crisp in the oven. Flour tortillas work best here because they fold easily and don’t crack.
Cheese melts into the filling to create that irresistible gooey, cheesy texture. I like using a Mexican blend, but you can use whatever shredded cheese you have on hand.
Cooking spray helps the tacos crisp up in the oven.
Olive oil is used to sauté the walnut-lentil mixture.

How to serve Walnut Lentil Baked Tacos

Pair with cilantro lime rice and spicy black beans for a more filling meal.
Add a simple side salad with a zesty lime vinaigrette to balance the richness.
Top with shredded lettuce, diced tomatoes, and sliced jalapeños for extra crunch and freshness.
Spoon a little pico de gallo over the tacos just before serving.
Add pickled red onions on top for a tangy pop of flavor.

Substitutions and variations

Walnuts – Almonds or pecans are both great substitutes that offer a similar crunch.
Green bell pepper – Red, orange, or yellow bell peppers work just as well and add a slightly sweeter flavor.
Red onion – If you don’t have any red onions on hand, white onions, yellow onions, or shallots can be used instead.
Cheese – Feel free to use any shredded cheese, including cheddar, Monterey Jack, pepper jack, or a dairy-free alternative!
Flour tortillas – Flour tortillas are your best bet for this recipe, as they’re much easier to fold without cracking. If you’d like to use corn tortillas instead, wrap them in a damp paper towel and microwave for 20-30 seconds to soften them before filling and folding.

Quick recipe tips

Keep the walnuts and veggies slightly chunky to add more texture to the filling.

Flip halfway to ensure both sides get golden and crispy.

Prep ahead by making the filling in advance and storing it in the fridge.

Step-by-step instructions

Prepare the filling: Pulse the walnuts in a food processor until roughly chopped. Add the onion, garlic, and bell pepper and pulse again until finely chopped.

Cook the mixture: Heat the olive oil in a large skillet over medium heat. Add the walnut mixture and cook for 4-5 minutes, until softened. Stir in the lentils and seasonings and cook until well combined.

Assemble the tacos: Arrange the tortillas on one or two baking sheets. Spoon the filling onto one half of each tortilla and sprinkle with cheese.

Melt the cheese: Bake for 3-4 minutes at 375° F, or until the cheese is melted.

Fold and crisp: Fold the tortillas in half, lightly coat both sides with cooking spray, and return to the oven.

Bake until crispy: Bake for 15-20 minutes, flipping halfway through, until golden brown and crisp.

Make ahead & storage

These Cheesy Walnut Lentil Baked Tacos are a great option for busy weeknights. Prep the walnut-lentil filling ahead of time, then simply assemble and bake next time taco night rolls around!

Meal prep

Make the filling ahead: Prepare the walnut-lentil mixture up to 4 days in advance and store it in an airtight container in the fridge.
Prep the tacos: For the crispiest texture, wait to assemble and bake the tacos until you’re ready to eat them.
Bake when ready: When you’re ready for dinner, simply scoop the filling into the tortillas, add the cheese, and bake until crispy and golden.

Storing leftovers

Fridge: Store leftover baked tacos in an airtight container in the refrigerator for up to 3 days.
Reheat for the best texture: Warm the tacos in the oven, air fryer, or toaster oven to help bring back their crispy texture. The microwave works in a pinch too, but the tortillas will be softer.
Store the filling separately: If you know you’ll wind up with leftovers, storing the walnut-lentil filling separately can keep the tortillas from getting soggy.

Freezing

Freeze the filling: The walnut-lentil filling freezes well and can be stored in a freezer-safe container for up to 3 months.

FAQ
