Step-by-Step Instructions
Let’s build this masterpiece step by step.
Preparing the Ground Beef
Heat olive oil in a large skillet over medium heat. Add chopped onions and sauté until translucent. Toss in the garlic and stir for about 30 seconds.
Add the ground beef. Cook until browned, breaking it apart as it cooks. Season with salt and pepper. Drain excess grease if necessary.
Cooking the Mushrooms
In the same pan, add sliced mushrooms. Let them cook down until tender and slightly caramelized. This step is key, mushrooms release water, so cook until most of it evaporates.
Combine the mushrooms with the beef mixture.
Making the Creamy Sauce
Pour in heavy cream or stir in cream of mushroom soup. Let it simmer for 5–7 minutes until slightly thickened. The sauce should coat the meat mixture without being runny.
Taste and adjust seasoning.
Assembling the Bake
Preheat your oven to 375°F (190°C).
In a baking dish:
- Add a layer of beef and mushroom mixture.
- Add a layer of pasta (if using).
- Sprinkle mozzarella and cheddar.
- Repeat layers.
Finish with a generous cheese layer on top.
Baking to Golden Perfection
Bake for 20-25 minutes until the cheese is melted and bubbly. Broil for 2-3 minutes for that golden, slightly crispy top.
Let it rest for 10 minutes before serving.
If you enjoy oven-baked comfort dishes like the Sheet Pan Broccoli Tortellini Bake, you’ll recognize how proper heat distribution creates that irresistible golden finish.
Similarly, casseroles such as Jalapeño Popper Chicken Casserole show how cheese forms a sealing layer that locks in moisture while creating flavor contrast.

FAQs
Can I use canned mushrooms instead of fresh?
