2. Brown the Beef
In a skillet, heat the olive oil over medium heat. Add the ground beef and cook until fully browned, using a spoon to break it up as it cooks. Drain off any extra fat. Season with garlic powder, salt, and pepper, stirring to combine.
3. Mix & Assemble
In a large bowl, stir together the cooked pasta, browned beef, and Alfredo sauce until everything is well coated. Pour the mixture into a greased 9×13-inch baking dish. Sprinkle the top evenly with mozzarella and Parmesan cheeses.
4. Bake
Place the casserole in the oven and bake for 25–30 minutes, or until the cheese is melted and bubbling. Let it rest for a few minutes before serving.
5. Garnish & Serve
Top with a sprinkle of fresh parsley, if using, and serve warm. Pair it with garlic bread or a crisp green salad for a complete meal.
💡 Tips & Variations
Cheese lovers: Add extra mozzarella or stir in a bit of ricotta for added creaminess.
Make ahead: Assemble the casserole ahead of time, cover, and refrigerate. Bake when ready to serve.
Add-ins: Mix in sautéed mushrooms, spinach, or sun-dried tomatoes for a flavor twist.
