French Onion Stuffed Mushrooms

French Onion Stuffed Mushrooms

Caramelized onions, beef broth, bread crumbs and Parmesan cheese come together to make savory French Onion Stuffed Mushrooms.
Servings: 12 mushrooms
Prep Time: 20 minutes
Cook Time: 15 minutes
Total Time: 35 minutes

Ingredients

  • 16 ounces button mushrooms
  • 3 tablespoons unsalted butter, divided
  • 1 large Vidalia Onion
  • 1 teaspoon Italian seasoning
  • 1 tablespoon Worcestershire sauce
  • 2 tablespoons panko bread crumbs
  • 1/4 cup Parmesan cheese, shredded, plus one tablespoon to garnish
  • 1 tablespoon parsley, fresh, chopped

Instructions

  • Preheat the oven to 350 degrees Fahrenheit.
  • In a medium non-stick skillet over medium heat, add two tablespoons of butter and allow it to melt. Add sweet onion slices and one teaspoon of Italian seasoning to the skillet. Cook for about 15 minutes, until caramelized. Stir occasionally to cook the onions evenly.
  • While the onions are cooking, spray the bottom and sides of a shallow baking dish with cooking spray. Clean mushrooms by brushing away any dirt and removing the stems. Place the mushroom caps in the baking dish.
  • When the onions become caramelized, add the Worcestershire sauce, Panko bread, and one more tablespoon of butter. Stir until butter is melted and ingredients are combined.
  • Remove the pan from the heat and stir in the Parmesan cheese. Using a tablespoon, fill each mushroom cap with onion filling.
  • Bake the stuffed mushrooms for 15 minutes at 350 degrees Fahrenheit. Remove from the oven and top each mushroom with chopped parsley and another pinch of shredded Parmesan cheese. Recipe makes 12 mushrooms or 6 servings.

Equipment

  • 1 medium non-stick skillet
  • 1 shallow baking dish

Notes

Tips:
  • Cover the mushrooms with foil for the first 5 minutes of baking so mushrooms don't become too browned when baking. Cook for the last 10 minutes uncovered.
  • Use shredded Parmesan instead of finely grated cheese so that it adds to the texture of the filling and can be seen as a garnish on top.
  • Be sure to spray your baking dish with cooking spray before adding the mushrooms so they don't stick to the dish.
