Fresh green parsley leaves are scattered across the pizza, adding a bright contrast to the warm colors of the cheese and meatballs. The edges of the pizza crust are golden brown, and the whole pizza is set against a white marbled texture. photo taken with an iphone --ar 4:5 --v 7

Ingredients

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

Instructions

Step 1: Preheat the oven to 400°F and line a baking sheet with parchment paper.
Step 2: In a large bowl, combine the ground turkey, egg, ¾ cup mozzarella, onion powder, garlic powder, Italian seasoning, and salt. Mix gently until just combined.
Step 3: Shape the mixture into 1.5-inch meatballs and place them evenly on the prepared baking sheet.
Step 4: Bake the meatballs for 25 minutes or until cooked through and golden on the outside.
Step 5: Transfer the baked meatballs to a casserole dish. Pour the low-carb tomato sauce evenly over them. Sprinkle the remaining 1 cup mozzarella and parmesan cheese on top.
Step 6: Bake the casserole uncovered for 15–20 minutes until the cheese is melted and bubbly.
Step 7: For a golden top, broil the casserole for 2–3 minutes carefully watching to avoid burning.
Step 8: Let the casserole rest for 5 minutes before garnishing with fresh basil or parsley, if desired. Serve hot.

Tips & Variations

For juicier meatballs, mix in a tablespoon of almond flour or grated parmesan to bind the meat.
Use ground beef or pork if you prefer a richer flavor over turkey.
Swap fresh herbs like oregano or thyme for Italian seasoning to change up the flavor profile.
Try adding a few crushed red pepper flakes to the sauce for a spicy kick.
Make this recipe dairy-free by using a dairy-free cheese alternative and omit parmesan.

Storage

Store leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven until warmed through. This dish also freezes well; freeze in a sealed container for up to 2 months and thaw overnight in the fridge before reheating.
