Cook the fettuccine pasta according to package instructions. Drain and set aside.
In a skillet over medium heat, cook ground beef until browned. Season with salt and pepper, then drain excess fat.
Add heavy cream to the skillet and bring to a simmer. Stir in garlic powder, onion powder, cheddar cheese, and mozzarella cheese until melted and smooth.
Toss the cooked pasta into the cheese sauce until well coated.
Serve the pasta topped with crumbled bacon and additional cheese if desired.
