10 Servings

Ingredients

  • 1 pound lean ground beef
  • ¼ teaspoon black pepper
  • 1 teaspoon salt
  • 1 teaspoon seasoned salt
  • 1 teaspoon dried parsley
  • 3 large eggs
  • 2 tablespoons unsalted butter
  • 1 pound mushrooms sliced
  • 6 ounces cream cheese softened to room temperature
  • 1 cup shredded or grated cheese Parmesan, mozzarella, or cheddar

Instructions
 

Preheat the Oven

  1. Preheat the oven to 350°F (175°C) to ensure it reaches the correct temperature before baking.

Cook the Ground Beef

  1. In a large skillet over medium heat, cook the ground beef until it is browned and crumbly. Season with salt and black pepper while cooking. Remove from heat and allow to cool slightly.

Prepare the Cream Cheese Mixture

  1. Using a hand or stand mixer, beat the softened cream cheese until smooth. Add the eggs one at a time, mixing thoroughly after each addition until well combined.

Combine with Ground Beef

  1. Stir the cooled ground beef into the cream cheese mixture until evenly incorporated.

Transfer to Baking Dish

  1. Place the beef and cream cheese mixture into a small baking dish. Press down lightly to create an even layer.

Sauté the Mushrooms

  1. In the same skillet, melt the butter over medium heat. Add the sliced mushrooms, seasoned salt, dried parsley, and additional black pepper to taste. Cook until the mushrooms are soft and beginning to brown.

Assemble and Bake

  1. Spread the cooked mushrooms evenly over the beef mixture in the baking dish. Bake for 20–25 minutes, or until the casserole is set in the center.

Add Toppings

  1. If desired, sprinkle breadcrumbs or crushed crackers over the top during the last 10 minutes of baking for added texture. Finally, add the shredded cheese and allow it to melt before removing the dish from the oven.
