Ingredients:
- lb (450g) Elbow Macaroni, Rotini, or Shells
- tbsp Olive Oil or Vegetable Oil
- lb (450g) Lean Ground Beef (85/15)
- small Yellow Onion, finely diced
- cloves Garlic, minced
- /2 tsp Salt
- /4 tsp Black Pepper
- /4 cup (60ml) Ketchup
- tbsp Yellow Mustard
- tbsp Worcestershire Sauce
- tbsp Pickle Relish
- /2 cup (120ml) Beef Broth or Water
- /2 cup (120ml) Heavy Cream (Optional)
- cups (225g) Shredded Sharp Cheddar Cheese (divided)
- cup (115g) Shredded Monterey Jack or Mozzarella
Instructions:
- Boil water, salt heavily, and cook the pasta according to package directions until al dente. Drain well, reserving about 1/2 cup of the starchy cooking water.
- While pasta cooks, heat oil in a large deep skillet over medium-high heat. Add ground beef, breaking it up. Cook until fully browned (5-7 minutes). Drain off any excess grease.
- Add the diced onion to the beef and cook until softened, about 3 minutes. Add the minced garlic and cook for 1 minute more until fragrant.
- Stir in the ketchup, mustard, Worcestershire sauce, and pickle relish. Cook for 1 minute.
- Pour in the beef broth (and heavy cream, if using). Bring to a gentle simmer, scraping up browned bits. Season with salt and pepper.
- Reduce heat to low. Stir in half of the shredded cheese mixture until completely melted and smooth. If the sauce is too thick, stir in a splash of the reserved pasta water.
- Add the drained pasta directly into the cheesy beef sauce. Stir well to coat every piece.
- Remove the skillet from the heat. Sprinkle the remaining cheese over the top. Cover the skillet tightly for 2-3 minutes to allow the top layer of cheese to melt completely. Serve immediately.
