Stuffed Mushroom Casserole

This Stuffed Mushroom Casserole layers sautéed onions, garlic, and sliced mushrooms with mozzarella and parmesan cheeses, blended with Italian-seasoned breadcrumbs. Butter is incorporated into the breadcrumbs to create a rich topping that bakes to golden and bubbly perfection. The dish offers a tender, flavorful mushroom base with a crisp, cheesy crust, suitable as a savory side or appetizer alongside a main course.

Description

The recipe starts by sautéing finely chopped onions and garlic with sliced button or cremini mushrooms in butter until golden and tender. These cooked vegetables are transferred to a baking dish, then layered with shredded mozzarella and grated parmesan cheese. Half the breadcrumb mixture—made by coating Italian-seasoned breadcrumbs in melted butter—is stirred into the mushroom mixture, with the remainder sprinkled on top for a crunchy topping.

Baking at 350°F for 10-15 minutes melts the cheeses and crisps the breadcrumbs, forming a casserole with moist mushroom filling and a golden, flavorful crust. Fresh parsley garnish adds a bright finish.

This casserole works well served hot as a side dish with meats or vegetarian mains. The note suggests it pairs deliciously with stroganoff and may be enriched by swirling in a spoonful of light sour cream before serving to add creaminess.

Instructions

  1. Pre-heat oven to 350 degrees F.

  4. Transfer veggies to a baking dish and sprinkle with cheese. Use as much or as little as you'd like here.
  5. TIP: If you're using a cast iron skillet you can actually bake everything right in the skillet!
  6. Melt 4 TBSP butter and combine with seasoned breadcrumbs. Mix well to coat.
  7. Add about half the breadcrumbs to the mushrooms and stir slightly. Then top with the remainder.
  8. Bake at 350 degrees F for 10-15 minutes or until golden and bubbly
  9. Serve piping hot with your favorite main dish!

Notes
