Ingredients
  

For the Meatballs
  • 2 pounds ground turkey or ground beef or pork
  • 1 large egg
  • ¾ cup shredded mozzarella cheese
  • 1 teaspoon onion powder
  • 1 teaspoon garlic powder
  • 1 teaspoon Italian seasoning
  • 1 teaspoon salt
For the Casserole
  • 1 cup low-carb tomato sauce no added sugar
  • 1 cup shredded mozzarella cheese additional for topping
  • ½ cup grated parmesan cheese
  • Fresh basil or parsley for garnish (optional)

Method
 

Preparation
  1. Set your oven to 400°F and line a baking sheet with parchment paper.
  2. In a bowl, combine ground turkey, egg, mozzarella, and seasonings. Mix until just combined—don’t overdo it!
  3. Form 1.5-inch meatballs and place them on the baking sheet. Bake for 25 minutes until cooked through.
Assembling the Casserole
  1. Place baked meatballs in a casserole dish. Top with tomato sauce, remaining mozzarella, and parmesan.
  2. Bake uncovered for 15–20 minutes until cheese is melted and bubbly. Broil for an additional 2–3 minutes for a golden top!
  3. Let rest for 5 minutes. Garnish with basil or parsley and serve hot.

Notes

This casserole keeps well in the fridge for up to 4 days or can be frozen for about 3 months. To reheat, pop it in the oven at 350°F until heated through.
