01 - Preheat oven to 375°F. Lightly grease a 12-cup muffin tin with nonstick spray or butter.
02 - Cook elbow macaroni in salted boiling water until just al dente. Drain and set aside.
03 - Melt butter over medium heat in a saucepan. Add minced garlic and sauté for 1 minute.
04 - Whisk in flour and cook for 1 minute. Gradually pour in milk and heavy cream, whisking constantly until smooth and thickened, about 3–4 minutes.
05 - Reduce heat to low. Stir in Parmesan, mozzarella, Alfredo sauce, roasted red pepper, salt, pepper, and smoked paprika until cheese is melted and sauce is creamy.
06 - Remove saucepan from heat. Gently fold in the cooked macaroni and beaten egg; mix until fully combined.
07 - Spoon macaroni mixture evenly into each prepared muffin cup, pressing gently to compact.
08 - In a small bowl, combine panko breadcrumbs and additional Parmesan cheese. Sprinkle evenly over each cup.
09 - Bake in the oven for 18–22 minutes until the tops are golden and the cups are set.
10 - Let cool in the tin for 5 minutes. Run a small knife around each edge to loosen and carefully lift out. Garnish with chopped parsley and serve warm.
