  • 3 Large eggs
  • 1 lb. Sliced mushrooms
  • 2 tsp. Minced garlic
  • 2 Tbsp. Chopped fresh parsley
  • 6 oz. Cream cheese, softened
  • 1 lb. Ground beef
  • 1 tsp. Seasoning salt
  • Salt and pepper to taste
  • 2 Tbsp. Unsalted butter
  • Parmesan cheese for garnish


  1. Preheat Oven: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish with non-stick cooking spray.
  2. Saute Mushrooms: In a large skillet, melt the unsalted butter over medium heat. Add the sliced mushrooms and minced garlic to the skillet and sauté until the mushrooms are tender and golden brown, about 5-7 minutes. Remove from heat and set aside.
  3. Prepare Cream Cheese Mixture: In a mixing bowl, combine the softened cream cheese, chopped fresh parsley, and one egg. Mix until well combined and set aside.
  4. Cook Ground Beef: In the same skillet used for the mushrooms, cook the ground beef over medium heat until browned and no longer pink, breaking it apart with a spatula as it cooks. Season the beef with seasoning salt, salt, and pepper to taste.
  5. Assemble Casserole: Spread half of the cooked mushrooms evenly in the bottom of the prepared baking dish. Top with the cooked ground beef, followed by the remaining mushrooms.
  6. Add Cream Cheese Mixture: Spoon the cream cheese mixture over the mushrooms and ground beef, spreading it out evenly with a spatula.
  7. Bake: Place the casserole in the preheated oven and bake for 25-30 minutes, or until the center is set and the edges are golden brown.
  8. Serve: Once baked, remove the casserole from the oven and let it cool for a few minutes before serving. Garnish with grated Parmesan cheese and additional chopped parsley, if desired.

Cook’s Notes:

  • Variation: Feel free to customize this casserole to suit your taste preferences. You can add additional vegetables such as bell peppers, onions, or spinach for added flavor and nutrition.
  • Cheese: If you’re a cheese lover, sprinkle some shredded mozzarella or cheddar cheese on top of the casserole before baking for an extra cheesy finish.
