- 1 lb ground beef
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 8 oz sliced mushrooms (button or cremini)
- 1 can (10.5 oz) cream of mushroom soup
- 1/2 cup sour cream
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1/2 tsp Italian seasoning (optional)
- 1 1/2 cups shredded mozzarella cheese
- 1/2 cup grated cheddar cheese
- Fresh parsley, chopped (optional for garnish)
Instructions:
- Cook the Pasta:
Boil spaghetti in salted water according to package instructions until al dente. Drain and set aside. - Brown the Beef:
In a large skillet, heat olive oil over medium heat. Add chopped onion and garlic, cooking until softened (about 2 minutes). Add ground beef and cook until browned, breaking it up as it cooks. Drain any excess grease. - Add Mushrooms:
Stir in sliced mushrooms and cook for 4–5 minutes, until tender. Season with salt, pepper, and Italian seasoning if using. - Make the Creamy Sauce:
Lower the heat and stir in the cream of mushroom soup and sour cream. Let it simmer for 2–3 minutes until combined and creamy. - Assemble the Casserole:
Preheat the oven to 375°F (190°C). In a large mixing bowl, combine the cooked spaghetti with the creamy beef and mushroom sauce. Mix well. - Layer and Bake:
Transfer the mixture to a greased 9×13-inch baking dish. Top evenly with mozzarella and cheddar cheese. Bake uncovered for 20–25 minutes or until the cheese is melted, bubbly, and slightly golden on top. - Serve:
Garnish with chopped parsley and serve warm. This dish pairs perfectly with garlic bread and a fresh green salad.
