Step-by-Step Instructions
Prepare the Foundation
Preheat oven to 375°F and grease a 9×13-inch baking dish. If using pasta, cook according to package directions and drain. If using potatoes, dice and parboil until just tender.
Brown the Beef
In a large skillet over medium-high heat, brown ground beef with diced onion until meat is cooked through and onions are softened, about 8-10 minutes. Add minced garlic and cook 1 minute more. Season with Worcestershire sauce, salt, and pepper. Drain excess fat.
Create the Garlic Butter Sauce
In the same skillet, melt butter over medium heat. Add minced garlic and cook until fragrant, about 1 minute. Whisk in flour and cook for 2 minutes to eliminate raw flour taste. Gradually add milk while whisking constantly to prevent lumps. Cook until thickened, about 3-5 minutes. Season with salt.
Assemble the Casserole
Layer the cooked pasta or potatoes in the prepared baking dish. Add the drained diced tomatoes, then spread the beef mixture evenly over top. Pour the garlic butter sauce over everything, ensuring even coverage.
Add Cheese and Bake
Sprinkle cheddar and mozzarella cheeses evenly over the surface. Bake for 25-30 minutes until cheese is melted and bubbly, and edges are lightly golden.
Rest and Serve
Allow casserole to rest for 5-10 minutes before serving to let layers set properly and prevent burns from hot filling.
