How to Make the Mushroom Patties
Step 1: Cook the Mushrooms
Heat olive oil in a pan. Add onions and garlic, cook for 2–3 minutes. Add the chopped mushrooms and cook until all the moisture has evaporated—this takes around 8–10 minutes. Stir in soy sauce, salt, pepper, and paprika. Remove from heat and let it cool slightly.
Step 2: Form the Patties
Transfer the cooked mushroom mixture to a bowl. Add breadcrumbs and egg. Mix until combined. The texture should hold together when pressed—add more breadcrumbs if it’s too soft. Shape into two round patties.
Step 3: Grill the Patties
Heat a grill pan over medium heat. Grease lightly with oil or butter. Cook the patties for 4–5 minutes on each side, pressing gently to get grill marks and a crisp surface. Add cheese slices on top during the last minute if using.
Step 4: Assemble the Burger
Place lettuce on the bottom half of each bun. Add the mushroom patty, then layer with tomato, onion, pickles, and your favorite sauce. Top with the other half of the bun.
Serving Suggestions
Serve the burgers with a side of baked potato wedges, sweet potato fries, or a green salad. They’re also great with iced tea or a lemon soda on the side.
This Vegetarian Mushroom Burger cooked on a grill pan proves you don’t need meat to enjoy a bold, satisfying burger. It’s juicy, flavorful, and loaded with all the classic burger fixings—perfect for both vegetarians and curious meat-eaters alike.
