Preheat oven to 400°F. In a large bowl, combine all meatball ingredients and gently mix until incorporated.
Roll into 21 meatballs and arrange on parchment-lined baking sheets. Lightly spray with olive oil.
Bake for approximately 22–28 minutes, or until the internal temperature reaches 165°F.
Meanwhile, melt butter in a large skillet over medium heat. Add minced garlic and sauté for 30–60 seconds until fragrant.
Add marinara and simmer for 3–5 minutes. Reduce heat to low and stir in light whipping cream, Parmesan, and fresh basil until creamy.
Transfer baked meatballs into the sauce and gently coat.
Top with mozzarella and broil for 2–3 minutes until melted and bubbly. Garnish with fresh basil and enjoy!
