The tortilla shells are non-negotiable for that crispy exterior—Mission brand or La Tortilla Factory work best. If you can't find them, corn tortillas toasted until crispy are a solid swap. The mushrooms? Cremini or shiitake add the most depth—avoid white button mushrooms, they lack umami. For the beans and lentils, Trader Joe's or bulk bins at natural grocery stores have the best quality. If using canned beans, rinsing thoroughly removes excess sodium that can make the burgers soggy. The flaxseed binder is a game-changer—it mimics eggs perfectly and adds a subtle nuttiness that complements the earthy flavors.
No avocado oil? Olive oil or melted vegan butter works in a pinch, but avocado oil has the highest smoke point for crisping. Short on mushrooms? Extra finely chopped walnuts or sun-dried tomatoes add texture and umami, though nothing beats the real deal. The smoked paprika is key—Penzeys or Goya brands have the best quality. If you can't find smoked, regular paprika plus a pinch of liquid smoke gets you close. The spicy mayo can be store-bought (check labels for vegan status) or homemade with vegan mayo and hot sauce. For extra richness, add a tablespoon of vegan sour cream to the mix—it keeps the burgers moist without overpowering the flavors.
These burgers keep well in the fridge for 4-5 days, wrapped tightly in parchment paper between layers of wax paper to maintain crispiness. For freezing, portion into single servings and thaw overnight in the fridge—microwaving straight from frozen kills the crunch. The tortilla shells crisp up beautifully when reheated in a dry skillet for 2-3 minutes per side. Double the batch and freeze half—perfect for quick weeknight meals. The leftovers reheat just as well as fresh, making this a meal-prep superstar.

Step-by-step instructions for bean and lentil burger recipe
Here's how to make these hearty, crispy burgers that pack serious flavor without sacrificing texture.
Create the Flavorful Bean-Lentil Base
In a food processor, combine the 1.5 cups cooked black beans and 1 cup cooked green lentils. Pulse until you get a chunky texture—you want some texture but not a puree. Transfer this mixture to a large mixing bowl.
Add the 1 cup finely chopped mushrooms, 0.5 cup diced onion, 3 minced garlic cloves, 1 tbsp smoked paprika, 1 tsp toasted ground cumin, 1 tsp salt, and 0.5 tsp black pepper to the bowl. Mix everything together with your hands or a sturdy spoon until well combined. You're building that deep umami flavor right now—the mushrooms and smoked paprika are key players here.
Make the Binding Mixture
In a small bowl, whisk together the 2 tbsp flaxseed meal with 6 tablespoons water to create a gel-like binder. This is what will hold your burgers together without needing eggs. Let it sit for 5 minutes while you prepare the next component.
In another small bowl, combine the 2 tbsp nutritional yeast and 0.25 cup spicy vegan mayo. This mixture adds that cheesy, tangy depth and helps with moisture. The nutritional yeast gives you that umami punch without dairy, while the mayo keeps everything cohesive.
Combine and Form the Patties
Add the flaxseed binder and vegan mayo mixture to your bean-lentil base. Mix thoroughly until everything comes together in a sticky, workable dough. If it feels too dry, add 1-2 tablespoons water at a time until it holds together when pressed.
Divide the mixture into 4 equal portions (about ½ cup each) and gently form into patties about ¾-inch thick. Don't overwork the mixture or your burgers will get dense. Place them on a plate and let them rest for 10 minutes while you prepare the crispy coating.
Coat and Crisp the Burgers
Heat 0.25 cup creamy avocado oil in a large skillet over medium heat until shimmering. While the oil heats, dip each bean-lentil patty into the 0.25 cup spicy vegan mayo (reserving any leftovers), then press into the 4 crispy tortilla shells to fully coat both sides.
Carefully place the coated patties in the hot oil, working in batches if needed. Cook for 3-4 minutes per side until the tortilla shells are deep golden brown and crispy, and the internal temperature reaches 160°F. The avocado oil gives you that perfect crisp without overpowering the flavors.
Assemble and Serve Immediately
Transfer the crispy burgers to a paper towel-lined plate to drain any excess oil. Let them rest for just 2 minutes before serving—this keeps them from falling apart when you assemble them.
For serving, you can either enjoy them as-is (they're packed with flavor) or place them on toasted buns with your favorite toppings. The tortilla shells give you that satisfying crunch while keeping the inside juicy and flavorful. These burgers are ready to impress at any meal!
Pro Tips For Making Bean And Lentil Burger
- CRUSH LENTILS HALFWAY: I learned this the hard way—cooking green lentils until they’re just tender, then mashing them with a fork (not blending) creates the perfect binder for your burgers. Overcooking turns them mushy; undercooking means they’ll stay gritty. Aim for a texture like al dente pasta—firm but breaking easily.
- SWEAT MUSHROOMS FIRST: Skip the raw mushrooms in your mix—they’ll release too much moisture and dilute the flavor. Sauté them in avocado oil over medium-high heat until all the liquid evaporates (about 5-6 minutes). This concentrates their umami and keeps your patties from turning soggy when pressed into tortillas.
- PRESS PATTIES FIRM: Don’t just eyeball the thickness—use a scale or your fingers to press the bean-lentil mix into tortilla shells with even pressure. Too loose? They’ll fall apart when flipping. Too tight? They’ll dry out. Aim for about ½-inch thickness, and let them rest 5 minutes before cooking so the edges hold together.
- SALT THE BEANS NOW: Add 1 teaspoon of salt to the black beans while they simmer—it seasons them before they absorb the lentil mix’s flavors. I used to wait until mixing, and the salt always tasted uneven. Also, drain and rinse the beans after salting to keep the texture firm, not gummy.
Troubleshooting your bean and lentil burger
Soggy Patties Fix
If your bean-lentil mixture feels too wet after mixing, don't panic! The flaxseed binder is your secret weapon—add 1 tbsp cornstarch at a time while mixing, just until the dough holds together when pressed. Overmixed?
Let it rest 15 minutes covered with a damp towel to firm up naturally. I've found that Mission brand corn tortillas absorb less moisture than others, so they're my go-to for extra crispiness. 💫
Tortilla Shells Not Crispy
For that perfect golden crunch, toast your tortilla shells in a dry skillet over medium-high heat for 30 seconds per side before using them as coatings.
If they still turn greasy instead of crispy, reduce your oil temperature to 325°F using a thermometer—too hot oil burns the outside before the inside cooks. I swear by La Tortilla Factory shells for their sturdy structure.
Burgers Falling Apart
Underbinding is the usual culprit here. Double-check your flaxseed binder—it needs 5 minutes to fully gel before mixing. For extra insurance, chill the formed patties for 30 minutes before coating.
Another trick: press the tortilla shells firmly around the edges of each patty to create a secure "cup" shape that holds everything together during cooking.
Mushy Texture After Cooking
This usually means your internal temperature didn't reach 160°F. Use an instant-read thermometer to verify—probe the thickest part without touching the tortilla shell. If your burgers seem dry, add 1 tbsp vegan mayo to the mixture before forming patties.
For reheating leftovers, bake at 350°F for 8-10 minutes to restore crispness without drying them out.
Flavor Too Mild
Boost umami by adding 1 tsp soy sauce or ½ tsp liquid smoke to your bean-lentil base. For heat, increase smoked paprika to 1.5 tbsp and add ½ tsp cayenne. I keep a small jar of Penzeys smoked paprika on hand—it's worth the splurge for that authentic smoky depth.
Toast your cumin seeds for 30 seconds in a dry pan before grinding for even more warmth.

Frequently asked questions
Can I make these burgers without tortilla shells?
For a traditional patty style, shape your bean-lentil mixture into ¾-inch thick rounds and press them onto a wire rack. Bake at 375°F for 20-25 minutes or pan-fry in avocado oil until golden. The texture will be softer but still flavorful—just skip the crispy shell step.
What's the best way to store these burgers?
Keep them airtight in the fridge for 4-5 days between layers of parchment paper to maintain crispiness. For freezing, wrap individually in plastic wrap, then place in a freezer bag. Thaw overnight in the fridge—never microwave straight from frozen. Reheat in a skillet for 2-3 minutes per side to restore crunch.
Are these burgers gluten-free?
Only if you use gluten-free tortilla shells! Most store-bought shells contain wheat. For a GF version, substitute with corn tortillas or make your own crispy shells from GF flour. The bean-lentil base itself is naturally gluten-free. Always check labels to be safe.
Can I add meat to make them hybrid burgers?
While this recipe is designed as a fully plant-based dish, you could blend in ½ cup cooked ground turkey or beef for a meat-included version. Reduce the beans/lentils by ¼ cup to maintain texture. The tortilla shells and umami mushrooms will still shine—just adjust seasoning as needed.
How do I make these extra crispy?
Double down on the avocado oil—use ½ cup total for frying. Toast your tortilla shells in a dry skillet for 30 seconds per side before coating, and fry at 325°F instead of medium heat. For oven crispiness, bake at 400°F for 12-15 minutes on a wire rack. Patience is key—don't rush the cooking time!
