A delightful casserole combining savory beef, spinach, and a creamy sauce, topped with melted cheese.
Preheat your oven to 350°F (175°C).
Ensure your oven is fully preheated for even cooking.
In a large skillet, cook the ground beef over medium heat until browned. Drain any excess fat.
Use a wooden spoon to break up the beef into small pieces for even cooking.
Add the mushrooms, garlic, and oregano to the skillet. Sauté until the mushrooms are tender.
Stir frequently to prevent the garlic from burning.
Stir in the spinach and cook until heated through and most of the liquid has evaporated.
Press the spinach with a spoon to help release excess moisture.
Mix in the sour cream, salt, and pepper. Stir until well combined.
Taste and adjust the seasoning as needed.
Transfer the mixture to a casserole dish and spread evenly.
Use a spatula to ensure an even layer.
Sprinkle the mozzarella cheese evenly over the top.
For a golden crust, use a mix of mozzarella and Parmesan cheese.
Bake in the preheated oven for 30 minutes or until bubbly and golden on top.
Let the casserole rest for a few minutes before serving to set.
Serve warm and enjoy your delicious Creamy Spinach and Beef Bake.
Garnish with fresh parsley for a pop of color.
