Mix the Ingredients: Begin by grabbing a large mixing bowl and adding the lean ground beef. Sprinkle in the freshly grated Parmesan and shredded mozzarella, allowing their cheesy goodness to mingle. Add the lightly beaten egg, heavy whipping cream, minced garlic, and a pinch of salt and pepper. Combine gently, ensuring that all components are well incorporated without overworking the meat.

-
Preheat the Air Fryer: While shaping the meatballs, it’s an excellent time to preheat your air fryer to 375°F (190°C). This step is crucial, as it ensures your meatballs cook evenly and achieve that desired crispy exterior.

Prepare the Sauce: While the meatballs are cooking, you can prepare the sauce. In a small saucepan over medium heat, combine the tomato sauce, pesto, and heavy whipping cream. Allow it to gently simmer, stirring occasionally until it’s heated through and well combined—a creamy tomato sauce that perfectly complements your meatballs.
-
