Cook the fettuccine pasta according to package instructions until al dente. Drain and set aside.
In a large skillet over medium heat, brown the ground beef, breaking it apart as it cooks. Add the minced garlic and cook for another 1-2 minutes until fragrant. Drain excess fat if necessary.
Reduce heat to low, then add heavy cream, beef broth, cream cheese, Worcestershire sauce, onion powder, and garlic powder to the skillet. Stir until the cream cheese is fully melted and combined.
Add shredded cheddar cheese to the sauce, stirring until melted and well combined. Season with salt and pepper to taste.
Stir in the cooked pasta, allowing it to absorb the creamy sauce for a few minutes.
Optional: Add diced tomatoes, pickles, and chopped green onions for extra flavor and presentation. Mix well.
Serve hot and enjoy your loaded cheeseburger Alfredo pasta!
