Mushroom caps are filled with sautéed stems, sweet onion, garlic, rosemary, and sharp white cheddar, then topped with toasted breadcrumbs. Baked until tender and melty, they make an easy appetizer for parties, holidays, or dinner.
These stuffed mushrooms make use of the whole mushroom by chopping the stems into a savory filling with sweet onion, garlic, and fresh rosemary. Sharp white cheddar melts into the mixture, while buttery toasted breadcrumbs provide a contrasting crisp topping. The caps are lightly seasoned, filled, and baked until tender and the cheese is melted. A sprinkle of chives adds a fresh finish. Serve them warm as a party appetizer, holiday starter, or flavorful side alongside dinner.
