Step 1

Preheat the oven to 350°F (175°C). Grease a 9x13-inch casserole dish with butter or non-stick spray.

Step 2

In a skillet, cook the ground beef over medium heat, breaking it into crumbles, until browned. Season with salt and pepper. Remove from heat and set aside.

Step 3

In a food processor, blend cream cheese until smooth. Add eggs one at a time, blending after each addition. Pour this mixture into the cooked ground beef and stir to combine.

Step 4

Melt butter in the skillet and add mushrooms. Cook for 5–7 minutes until golden brown, then season with salt, pepper, and parsley.

Step 5

Layer the beef and cream cheese mixture in the greased dish. Top with sautéed mushrooms and optionally sprinkle grated cheese over the top.

Step 6

Bake in the preheated oven for 20–25 minutes, until the top is lightly browned and set. Remove from oven and let cool for 5–10 minutes before serving.
