Stuffed mushroom casserole is your favorite party appetizer but in casserole form! The mushrooms are cooked perfectly and seasoned nicely with garlic, Italian sausage, and Boursin. A cheesy, creamy sensation.

Ingredients

  • 2 tablespoons olive oil
  • 1.5 pounds hot Italian sausage
  • 1.5 pounds cremini mushrooms
  • 1.5 tablespoons garlic
  • 8 ounces cream cheese
  • 5.2 5.2 Gournay cheese product
  • 3 ounces low-moisture part-skim mozzarella cheese
  • 3 ounces Parmesan cheese
  • cooking spray
  • 1 cup panko
  • 2 tablespoons unsalted butter
  • 2 tablespoons parsley

Instructions

  1. 1

    Preheat oven to 350 degrees F (175 degrees C). Gather all ingredients.

  2. 2

    Heat 1 tablespoon of the oil in a large nonstick skillet over medium-high. Add sausage; cook, stirring often, until browned and crumbled, about 8 minutes.

  3. 3

    Using a slotted spoon, transfer cooked sausage to a large bowl, leaving drippings in skillet.

  4. 4

    Return skillet to medium-high. Add remaining 1 tablespoon oil to drippings. Add mushrooms; cook, stirring occasionally, until mushrooms are softened, browned, and have released most of their liquid, 8 to 10 minutes.

  5. 5

    Add garlic; cook, stirring constantly, until fragrant, about 30 seconds. Stir in cream cheese and Gournay cheese; cook, stirring constantly, until cheese is melted and evenly coating mushrooms, about 2 minutes.

  6. 6

    Transfer mushroom mixture to bowl with sausage, and stir in mozzarella and 1/2 cup of the Parmesan cheese until evenly combined.

  7. 7

    Spoon into an even layer in a 13- x 9-inch baking dish coated with cooking spray.

  8. 8

    Stir together panko, melted butter, and remaining 1/4 cup Parmesan cheese in a small bowl. Sprinkle evenly over top of mushroom mixture.

  9. 9

    Bake in preheated oven until topping is golden, about 25 minutes. Sprinkle with parsley. Serve hot.
