01 - Preheat oven to 375°F. Grease a 12-cup muffin tin with nonstick spray or butter.
02 - Boil elbow macaroni in salted water until just al dente. Drain and set aside.
03 - Melt butter in a medium saucepan over medium heat. Add minced garlic and sauté for 1 minute.
04 - Whisk flour into butter and garlic mixture; cook for 1 minute. Gradually add milk and cream, whisking until smooth and thickened, about 3 to 4 minutes.
05 - Lower heat. Stir in 1/2 cup Parmesan, mozzarella, Alfredo sauce, roasted red bell pepper, salt, black pepper, and smoked paprika. Mix until cheese is melted and sauce is homogenous.
06 - Remove from heat. Fold in cooked macaroni and beaten egg until thoroughly combined.
07 - Spoon macaroni mixture evenly into the prepared muffin cups, pressing gently to compact each portion.
08 - Mix panko breadcrumbs and remaining Parmesan in a bowl. Sprinkle a generous layer over each cup.
09 - Bake for 18 to 22 minutes, until tops are golden and cups are firm.
10 - Let cool in tin for 5 minutes. Run a small knife around edges to loosen, lift out carefully, and garnish with chopped parsley. Serve warm.
