Cook Pasta: Boil macaroni in salted water until al dente. Reserve 125ml pasta water, then drain.
Sauté Veggies: In a large skillet, melt butter over medium heat. Sauté garlic, onion & peppers for 4–5 mins until softened.
Add Beef: Crumble in beef. Cook 5–7 mins, breaking it up. Drain excess fat if needed. Season with salt, pepper, paprika & chili flakes.
Make it Creamy: Reduce heat to low. Stir in cream cheese, mozzarella & cheese slices. Melt into a silky sauce.
Bring it Together: Add cooked pasta & reserved pasta water. Stir until every noodle is coated in that creamy, cheesy goodness. Adjust sauce thickness as needed.
Garnish with fresh parsley before serving.
