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 your 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 shredded mozzarella, onion powder, garlic powder, Italian seasoning, and salt. Mix gently until just combined to avoid tough meatballs.
Step 3: Shape the mixture into 1.5-inch meatballs and place them evenly spaced on the prepared baking sheet.
Step 4: Bake the meatballs for 25 minutes, or until they are cooked through and slightly browned.

Step 5: Transfer the baked meatballs to a casserole dish. Pour the low-carb tomato sauce over them, then sprinkle with the remaining mozzarella and parmesan cheese.
Step 6: Bake the casserole uncovered for 15–20 minutes until the cheese melts and becomes bubbly. For a golden finish, broil for 2–3 minutes—watch carefully to prevent burning.
Step 7: Let the casserole rest for 5 minutes before serving. Garnish with fresh basil or parsley if desired, and enjoy hot.

Tips & Variations

Use ground beef or pork if you prefer a richer flavor instead of turkey.
Add crushed red pepper flakes to the meatball mix for a spicy kick.
Swap low-carb tomato sauce for homemade marinara to control ingredients.

Serve over zucchini noodles or cauliflower rice for a complete keto meal.

Storage

Store leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F until warmed through, or microwave in short intervals to avoid drying out the meatballs.

How to Serve

The dish shows many round meatballs covered in melted light beige cheese with some golden brown spots, placed evenly in a single layer over a smooth, creamy, light yellow sauce. Bright green chopped herbs are scattered on top, adding a fresh contrast. The meatballs have a slightly rough texture with visible bits of cooked tomato sauce in deep red and brownish shades. The food is served on a shallow white plate, set against a white marbled textured surface. Photo taken with an iphone --ar 4:5 --v 7
