French Onion Stuffed Mushrooms

MAKES: 12

COOK TIME: 30 Min

These French Onion Stuffed Mushrooms are baked to an absolutely perfect combo of crunchy inside and cheesy, velvety outside.

What You'll Need

1 pound large fresh mushrooms
3 tablespoons butter
1/2 cup finely chopped onion
1 packet onion soup mix
1 tablespoon water
1/4 cup plain bread crumbs
1/8 teaspoon black pepper
3 slices Swiss cheese, each slice cut into 4 squares

What to Do

Preheat oven to 375 degrees F. Gently clean mushrooms by wiping them with damp paper towels. Remove stems from 12 mushrooms; set aside caps. Finely chop mushroom stems and remaining whole mushrooms.
In a large skillet over medium heat, melt butter; cook onion 3 minutes, or just until soft. Stir in chopped mushrooms, onion soup mix, and water and cook 4 to 5 minutes, or until tender. Remove from heat and add bread crumbs and black pepper; mix well.
Using a teaspoon, stuff mushroom caps with stuffing mixture. Place on ungreased baking sheet.
Bake 12 minutes. Remove from oven, top each with a piece of cheese, and return to oven 5 minutes, or until cheese is melted and mushrooms are heated through. Serve immediately.

I made these for Christmas as an appetizer and they are really good. With the amount of stuffing this makes you could probably fill another 6 mushrooms. They should not be overstuffed because they become too hard to eat as a finger food. Another cheese, like provolone, or ?? would also work as the Swiss seemed a little week.

This looks amazing! Can I make this a day before my party? I would get to the point of just stuffing the mushrooms and refrigerate. The day of the party I would then melt the cheese and serve. Just curious as not sure they would get soft and watery. Please let me know. Thank you!!
