Step 1

Combine eggs, chicken, prosciutto, panko, basil, salt, black pepper, crushed red pepper, garlic, and 1 ounce of the Parmesan in a large bowl. Gently mix with your hands to thoroughly combine, taking care not to overmix. Shape into 12 (1¾-inch) balls (about 2 ounces each).

Step 2

Preheat oven to 450°F. Heat olive oil in a large skillet over medium-high. Cook meatballs in a single layer, turning occasionally, until browned on all sides, 8 to 12 minutes. Transfer to a plate. Reduce heat to medium. Add wine to skillet; cook, scraping bottom of skillet to release browned bits, until reduced to about 2 tablespoons, 1 to 2 minutes. Stir in marinara sauce. Arrange meatballs in skillet in a single layer; turn to coat in sauce. Sprinkle with mozzarella cheese and remaining 1 ounce Parmesan.

Step 3

Transfer skillet to preheated oven; bake until mozzarella cheese is melted and beginning to brown and internal temperature of meatballs registers 165°F, 10 to 14 minutes. Garnish with basil leaves. Serve with garlic bread, cooked spaghetti, or zucchini "noodles."
