Ingredients
Mushroom Veggie Patties
- 2 tablespoons olive oil divided
- 8 oz cremini or button mushrooms finely chopped
- ½ small yellow onion finely diced
- 2 cloves garlic minced
- 1 teaspoon soy sauce or vegetarian Worcestershire
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ½ teaspoon dried thyme or Italian seasoning
- ½ cup cooked brown rice or quinoa
- ½ cup breadcrumbs or panko
- 1 large egg or flax egg
- ½ cup shredded Swiss cheese
Burger Components
- 4 burger buns brioche, potato, or whole wheat
- 4 slices Swiss cheese for melting on patties
- 1 cup sliced mushrooms for topping, optional
- 1 tablespoon butter or olive oil for sautéing topping mushrooms
- 4 lettuce leaves
- 4 tomato slices
Garlic Mayo (or Sauce of Choice)
- ½ cup mayonnaise
- 1 small garlic clove finely grated
- 1 teaspoon lemon juice
- Salt to taste
Instructions
Make the patties
- Heat 1 tablespoon olive oil in a skillet over medium heat. Cook chopped mushrooms until moisture evaporates and they brown, about 6–8 minutes. Add remaining oil, onion, and garlic. Cook 3–4 minutes until soft. Stir in soy sauce, salt, pepper, and thyme. Remove from heat and cool slightly.
- In a bowl, mix mushroom mixture with rice, breadcrumbs, egg, and shredded Swiss. Form into 4 patties. Chill 15–20 minutes.
Cook patties
- Pan-sear patties in a lightly oiled skillet over medium heat for 4–5 minutes per side until golden. Add Swiss cheese slices on top during the last minute and cover to melt.
Prepare toppings
- Sauté sliced mushrooms in butter or olive oil until golden, 4–5 minutes. Season lightly with salt.
- Toast burger buns until golden.
Make garlic mayo
- Stir mayonnaise, garlic, lemon juice, and salt until smooth.
Assemble burgers
- Spread garlic mayo on both bun halves.
- Layer bottom bun → lettuce → mushroom Swiss patty → sautéed mushrooms → tomato → top bun.
Notes
- Finely chopping the mushrooms helps remove excess moisture and gives the patty a meatier texture.
- Letting the patties chill before cooking improves structure and prevents crumbling.
- Swiss cheese can be swapped for provolone, Gruyère, or mozzarella if desired.
- For a vegan version, use a flax egg and dairy-free Swiss-style cheese.
- If the mixture feels too wet, add 1–2 tablespoons extra breadcrumbs; if too dry, add a spoonful of mayo or water.
- Patties can be made up to 24 hours in advance and stored covered in the refrigerator.
- These burgers freeze well before cooking; thaw overnight in the fridge before pan-searing.
- Best cooked in a skillet or grill pan; if grilling outdoors, use foil or a grill mat to prevent sticking.
FAQ
Can I make these burgers gluten-free?
Yes. Use gluten-free breadcrumbs and serve the patties on gluten-free buns or lettuce wraps.
Can I bake the patties instead of pan-frying?
You can bake them at 400°F (205°C) for about 20–25 minutes, flipping halfway, though pan-searing gives the best crust.
What mushrooms work best for this recipe?
Cremini or button mushrooms are ideal, but you can also use a mix with portobello for deeper flavor.
Can I make the patties ahead of time?
Yes. The patties can be shaped and refrigerated up to 24 hours before cooking.
What sauces pair well with a mushroom Swiss veggie burger?
Garlic mayo, Dijon mustard, honey mustard, or a light aioli all complement the savory mushroom flavor well.
Can I serve this without a bun?
Absolutely. The patty works well over greens, in a lettuce wrap, or alongside roasted vegetables for a lighter meal.
