Ingredients
- 4 large (about 8 oz each) portobello mushrooms
- 1/4 cup (softened) goat cheese
- 1/2 cup shredded cheddar cheese
- 1/2 cup shredded mozzarella cheese
- 4 brioche buns
- 1/2 tsp garlic powder
- 1/2 tsp dried oregano
- 2 tbsp olive oil
Instructions
- Step 1: Preheat oven to 375°F (190°C). Remove mushroom stems and gills, then brush caps with 1 tbsp olive oil. Season both sides with garlic powder, oregano, 1/4 tsp salt, and 1/8 tsp pepper. Place gill-side up on a baking sheet and roast for 12 minutes until tender.
- Step 2: While mushrooms roast, mix goat cheese, cheddar, and mozzarella in a bowl. Spoon 2 tbsp cheese mixture into each mushroom cap (filling will mound slightly).
- Step 3: Return mushrooms to oven and bake for 8-10 more minutes until cheese is fully melted and bubbly, and mushroom edges are slightly crisp.
- Step 4: Toast brioche buns in a skillet over medium heat for 1-2 minutes per side. Assemble burgers by placing a stuffed mushroom on each bun, then top with extra melted cheese if desired.
