How to Make Keto Meatball Casserole
Step 1: Preheat the Oven
Preheat your oven to 400Β°F (200Β°C). Spray your casserole dish with cooking spray to prevent sticking.
Step 2: Prepare the Meatballs
In a mixing bowl, combine all meatball ingredients:
1. Add ground turkey, Italian sausage, shredded zucchini, egg, onion, garlic, basil, and salt.
2. Mix thoroughly until well combined.
3. Form about 24 meatballs and place them in the prepared casserole dish.
Step 3: Bake the Meatballs
Bake in the preheated oven for about 30 minutes or until cooked through. Carefully drain any excess liquid from the casserole dish.
Step 4: Add Sauce and Cheese
Top the baked meatballs with marinara sauce and sprinkle with mozzarella and parmesan cheese. Return to the oven for an additional 10-15 minutes or until the cheese is melted.
Step 5: Optional Broiling
For an extra layer of flavor, broil for 3-4 minutes at the end to toast the cheese lightly. Keep an eye on it as cheese can burn quickly under high heat.
