I am not a vegetarian, but I lean heavily into a vegetable-forward life simply by nature of being a gardener. When it comes to plant-based meals, I’ve no interest in making exact copies of animal products. Vegetables deserve to stand on their own, and these burgers do exactly that. They are earthy, smoky, deeply savory, and packed with texture from the mushrooms and chickpeas. This recipe has earned a permanent spot in our weeknight rotation. It’s adapted from one of my favorite cookbooks, Cool Beans by Joe Yonan — you can shop my entire cookbook collection here. The technique of baking the patties first, then pan-frying them, is the key to burgers that hold together and develop a beautiful crust.
The mushrooms are everything
Do not skip the step of cooking the mushrooms down properly. You want them deeply golden, almost caramelized, with all of their water cooked off. If they’re still pale and wet when you add them to the beans, your patties will be soggy and fall apart. Take the full 10-12 minutes, let them sizzle undisturbed, and wait until they smell intensely earthy and nutty. That is when they’re ready.

Bake first, then fry
This two-step cooking method is what makes these burgers reliable. Baking them first in the oven firms up the exterior and drives out excess moisture. Then a quick sear in a hot pan gives you that golden, crackly crust that makes a great burger. If you skip the baking and go straight to the pan, they will crumble. Trust the process — it’s worth the extra step.
Skip the bun — lettuce wraps are the move
Something about beans on bread always felt too heavy to me, so I started serving these in crisp iceberg lettuce cups and never looked back. The cold crunch of the lettuce against the warm, smoky patty is perfect. Top them however you like — I go with sliced tomato, red onion, cucamelon relish, and avocado. My partner adds a chunk of parmesan to his, which sounds odd but works beautifully.
On the side: These are excellent alongside air fryer sweet potato fries with a chili-mayo dipping sauce. Or keep it simple with a handful of good chips and a cold drink.

Smoky Black Bean and Mushroom Burgers with Lettuce Wraps
| Prep: 20m | Cook: 40m | Total: 1h |
Hearty, deeply savory veggie burgers loaded with black beans, garbanzo beans, and caramelized mushrooms. Baked first for structure, then pan-fried until crispy. Served in cool, crunchy lettuce wraps with all the toppings you want. These are not trying to be meat — they are something better.
Ingredients
For the burgers:
- 2 tablespoons olive oil, divided
- ½ yellow onion, finely diced
- 8 ounces cremini mushrooms, finely chopped
- 3 cloves garlic, minced
- 1 teaspoon ground cumin
- ½ teaspoon smoked paprika
- ½ teaspoon kosher salt
- ¼ teaspoon freshly ground black pepper
- 1 (15-ounce) can black beans, drained and rinsed
- 1 (15-ounce) can garbanzo beans, drained and rinsed
- 1 tablespoon ground flaxseed mixed with 3 tablespoons water (flax egg)
- 1 large egg
- ½ cup panko breadcrumbs
- 1 tablespoon soy sauce or tamari
For serving:
- 1 head iceberg lettuce, leaves separated into cups
- 1 ripe avocado, sliced
- 1 large tomato, sliced
- ½ red onion, thinly sliced
- Cucamelon relish or pickles of your choice
- Spicy mayo (mayonnaise mixed with chili paste to taste)
Instructions
Cook the vegetables:
- Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the diced onion and cook, stirring occasionally, until softened and translucent, about 4-5 minutes. Add the chopped mushrooms, garlic, cumin, smoked paprika, salt, and pepper. Cook for 10-12 minutes, stirring only every few minutes, until the mushrooms are deeply golden, all of the moisture has cooked off, and they smell intensely earthy and nutty. The pan should look almost dry. Transfer to a large mixing bowl and let cool for 5 minutes.
Make the burger mixture:
- Preheat the oven to 375°F. Line a baking sheet with parchment paper and lightly oil it.
- Add the black beans and garbanzo beans to the bowl with the mushroom mixture. Use a potato masher or fork to smash roughly — you want about half the beans mashed and half left chunky for texture. Stir in the flax egg, regular egg, panko breadcrumbs, and soy sauce. The mixture should hold together when you squeeze a handful — if it feels too wet, add another tablespoon of panko. If too dry, a splash of water.
Bake the patties:
- Divide the mixture into 6 equal portions and shape into patties about ¾-inch thick. Place them on the prepared baking sheet. Bake for 15 minutes, then carefully flip and bake for another 10 minutes. They should feel firm to the touch and have a dry, slightly cracked surface. This step is what keeps them from falling apart in the pan.
Pan-fry and serve:
- Heat the remaining 1 tablespoon of olive oil in a large skillet over medium-high heat. When the oil shimmers, add the baked patties and cook for 2-3 minutes per side, until a deep golden-brown crust forms. You should hear a steady sizzle — if it is quiet, the pan is not hot enough. Serve immediately in crisp iceberg lettuce cups with avocado, tomato, red onion, cucamelon relish, and a generous drizzle of spicy mayo.
Notes
- Do not rush the mushrooms. If they still look pale and wet, keep going. Undercooked mushrooms will make soggy patties. You want them deeply golden and almost dry in the pan.
- Make-ahead friendly. Shape the patties and refrigerate them (unbaked) for up to 24 hours. You can also freeze baked patties — reheat in a 375°F oven for 15 minutes straight from frozen.
- Swap the beans. Kidney beans or white beans work beautifully in place of the garbanzo beans. Use whatever you have on hand.
