Cheese Stuffed Mushrooms
These Cheese-Stuffed Mushrooms are a long-time family favorite. Mushrooms are sauteed and then stuffed with Parmesan cheese, breadcrumbs, mushrooms and onions for a hearty, flavorful vegetarian appetizer that everyone will enjoy.
Ingredients
- 3 Tbs. unsalted butter
- 24 white button mushrooms (2-8 oz. packages)
- 1/4 c. finely chopped onion
- 6 Tbs. grated Parmesan cheese
- 3 Tbs. Italian-seasoned bread crumbs I use Italian-style
- 1/2 tsp. black pepper
- 2 Tbs. milk
- 1 Tbs. chopped fresh parsley (optional, for garnish)
Instructions
-
Preheat broiler. Line a baking sheet with parchment paper or foil and set aside.
-
Clean mushrooms and remove stems from caps. Trim tip of stem and discard. Finely chop the rest of the stem.
-
In a skillet over low heat, melt butter. Add onions and chopped mushroom stems. Cook for 5 minutes, until translucent and slightly browned. With a slotted spoon, transfer to a mixing bowl and allow to cool slightly.
-
In same skillet, cook caps - cavity-side up- until browned and tender. Flip and cook until browned on other side. Transfer to a plate lined with paper towels to drain.
-
While mushrooms are cooking, add Parmesan cheese, bread crumbs, pepper, and milk to mushroom/onion mixture. Stir to combine. (If dry, add a teaspoon more milk. If too wet, add a teaspoon more breadcrumbs).
-
After mushrooms have been drained, arrange on the prepared baking sheet, cavities facing up. Stuff each mushroom with the prepared mixture.
-
Broil in preheated oven until browned, about 5-10 minutes. Garnish with chopped parsley, if desired. Serve immediately.
Recipe Notes
- This recipe yields about 24 mushrooms, 3 stuffed mushrooms per serving.
- Prep Ahead: Stuffed mushrooms may be prepared in advance. Follow directions, through assembly. Refrigerate until just before serving. Bake at 350F for 15 minutes, until hot throughout, before broiling for 5-10 minutes to brown.
- Variations: Add finely chopped bell peppers, in addition to or in lieu of onion. Switch out the cheese with another hard cheese (i.e. grated asiago cheese.) Add cooked crumbled bacon or diced pancetta to the stuffing.
