First, preheat your oven to 400°F. Line a large baking sheet with aluminum foil and give it a light spray of olive oil cooking spray. This will help the meatballs brown beautifully.

Now, in a large mixing bowl, combine the lean ground beef, mild Italian sausage, egg, breadcrumbs, grated parmesan cheese, very finely diced yellow onion, half & half, grated garlic, Italian seasoning blend, salt, and black pepper. Mix everything until it’s well combined but be careful not to overmix; we want tender meatballs, after all!

Using a 2-inch-sized cookie scoop, portion out about 15 meatballs. Gently flatten each meatball into a disc, and place a cube of mozzarella cheese right in the center. Carefully fold the sides of the disc up and around the cheese, shaping it into a perfectly round meatball.

Line the stuffed meatballs on your prepared baking sheet, placing them in rows. Bake them in your preheated oven for 20-25 minutes until they are lightly browned and cooked through.

While the meatballs are baking, warm up the marinara sauce in a medium skillet over medium-low heat. This will bring it to the perfect temperature for serving.

Once the meatballs are done, take them out and let them rest for about five minutes. Patience is a virtue, after all!

To serve, spoon some warm marinara sauce onto a serving plate, add the meatballs, and drizzle some additional sauce over the top. Finish it off with a sprinkle of grated parmesan cheese and a dash of fresh chopped parsley for that beautiful pop of color.

Enjoy these delightful Cheese Stuffed Meatballs as a satisfying main course!
