Instructions
Preheat the Oven
Set your oven to 375°F (190°C). Lightly grease a 9×9-inch baking dish.
Cook the Beef
Heat the olive oil in a skillet over medium heat. Cook the ground beef for 5–7 minutes until browned, draining excess fat if needed. Season with salt, pepper, and paprika.
Sauté the Vegetables
Add the onion and garlic to the skillet and cook for 2–3 minutes. Stir in the mushrooms and cook until softened and their moisture has evaporated, about 5–7 minutes. Add thyme and chili flakes if using.
Prepare the Creamy Mixture
In a bowl, whisk together the sour cream and heavy cream until smooth. Mix in half of the mozzarella cheese.
Assemble the Bake
Spread the cooked beef evenly in the baking dish. Add the mushroom mixture on top. Pour the creamy mixture over everything, then sprinkle with the remaining mozzarella and cheddar.
Bake
Bake uncovered for 25–30 minutes, or until hot, bubbly, and lightly golden on top.
Rest & Serve
Let the dish rest for 5–10 minutes before serving. Garnish with chopped parsley if desired.
