Mushroom Veggie Burgers

The first time I made these mushroom veggie burgers, my teenage brother took a bite and asked where I ordered takeout from. The mushrooms give them this incredible umami depth that makes you forget they are plant based, while the beans keep them satisfyingly hearty.

I hosted a summer cookout and served these alongside regular beef burgers. The mushroom ones disappeared first, with my meat loving friends going back for seconds. They have this perfect crispy outside and tender, juicy inside that you rarely find in veggie burgers.

Ingredients

• Cremini or button mushrooms: These provide the meaty texture and rich umami flavor that makes these burgers so satisfying, and chopping them finely helps them meld perfectly with the beans
• Black beans: The hearty protein base that holds everything together while staying creamy enough to keep the burgers moist
• Red onion and garlic: These aromatics build a flavor foundation that sweetens as it sautés
• Carrot and red bell pepper: They add sweetness and color while contributing to the overall vegetable bulk
• Rolled oats: The secret binder that keeps the patties together without making them dense or dry
• Egg or flax egg: Essential for holding the patties together during cooking
• Breadcrumbs: These add structure and help create that crispy exterior when pan frying
• Smoked paprika and cumin: The spice duo that gives these burgers their smoky, slightly barbecue like flavor profile
• Soy sauce: Just one tablespoon deepens the savory notes and ties all the flavors together
• Fresh parsley: Brightens everything up and adds a fresh herbal note
• Olive oil: For cooking the vegetables and achieving that golden brown crust on the patties

Instructions

Cook the vegetables until deeply flavorful:

Heat 1 tablespoon olive oil in a large skillet over medium heat, then add the chopped mushrooms, onion, garlic, carrot, and bell pepper, sautéing until soft and most moisture has evaporated, about 8 minutes, then let cool slightly.

Prepare the bean base:

In a large bowl, mash the black beans with a fork or potato masher, leaving some texture for better bite.

Combine everything:

Add the sautéed vegetables, oats, egg or flax egg, breadcrumbs, soy sauce, smoked paprika, cumin, salt, pepper, and parsley to the beans, mixing until well combined.

Let the mixture rest:

Wait 10 minutes so the oats and breadcrumbs can absorb moisture, which helps the patties hold together better.

Form the patties:

Divide the mixture into 4 equal portions and shape them into burger patties, pressing firmly but gently.

Cook to golden perfection:

Heat the remaining 1 tablespoon olive oil in the skillet over medium heat and cook patties for 4 to 5 minutes per side until golden brown and heated through.

Build your burgers:

Serve on toasted burger buns with your favorite toppings like lettuce, tomato, pickles, cheese, or sauces.

My friend who swore she hated veggie burgers tried these at a dinner party and asked for the recipe before she even finished her first bite. The combination of mushrooms and beans creates such a satisfying bite that nobody feels like they are missing out.

Making Them Vegan Friendly

Swap the regular egg for a flax egg made from 1 tablespoon ground flaxseed mixed with 3 tablespoons water and let sit for 5 minutes. Use tamari instead of soy sauce if you need to avoid gluten, and choose certified gluten free oats if that is a concern for you.

Get Creative With Add Ins

Handful of chopped walnuts or pecans add incredible crunch and healthy fats. A tablespoon of nutritional yeast boosts the cheesy flavor, or try adding some grated zucchini for extra moisture and vegetables.

Storage And Meal Prep

These burgers are meal prep heroes. Form the uncooked patties and freeze them between parchment paper for up to 3 months. Cooked patties keep well in the refrigerator for 4 to 5 days and reheat beautifully in a skillet or oven.

• Reheat frozen patties directly from frozen, just add a couple extra minutes per side
• Crumble leftover cooked burgers over salads or into grain bowls for quick protein
• Double the batch and freeze half for busy weeknight dinners

There is something deeply satisfying about making your own veggie burgers that actually hold together and taste incredible. These might just become your new go to for meatless mondays.

Recipe Questions

→ Can I make these mushroom veggie burgers ahead of time?

Yes, prepare the patties up to 24 hours ahead and store them covered in the refrigerator. You can also freeze uncooked patties for up to 3 months with parchment paper between each layer.

→ How do I keep the patties from falling apart?

The key steps are sautéing vegetables first to remove moisture, letting the mixture rest for 10 minutes so oats absorb liquid, and handling patties gently when forming and cooking. Chilling the mixture for 30 minutes before shaping also helps.

→ What's the best way to cook these burgers?

Pan-frying in olive oil over medium heat creates the best crispy exterior. Cook for 4-5 minutes per side until golden brown. You can also bake at 375°F (190°C) for 15-20 minutes, flipping halfway through.

→ Can I grill these mushroom veggie burgers?

Absolutely! Place chilled patties on a preheated grill over medium heat. Grill for 5-6 minutes per side, using a grill basket or foil to prevent sticking. Brush with oil halfway through cooking.

→ What toppings work well with these burgers?

Classic toppings like lettuce, tomato, pickles, and cheese pair perfectly. Try avocado, caramelized onions, or a tangy sauce like garlic aioli and spicy mayo for extra flavor dimensions.

→ How do I make these vegan?

Replace the egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water, rested for 5 minutes). Use vegan burger buns and skip cheese or choose a plant-based alternative.
