How to Make Keto Meatball Casserole
Step 1: Preheat the Oven
Preheat your oven to 400°F (200°C). Spray your casserole dish with cooking spray to prevent sticking.
Step 2: Prepare the Meatballs
In a mixing bowl, combine all ingredients for the meatballs:
1. Add ground turkey, Italian sausage, shredded zucchini, egg, minced onion, minced garlic, dried basil, and salt.
2. Mix thoroughly until well combined.
3. Form the mixture into about 24 meatballs and place them in your prepared casserole dish.
Step 3: Bake the Meatballs
Bake the meatballs in the preheated oven for 30 minutes or until cooked through. Be sure to check that they are no longer pink inside.
Step 4: Add Sauce and Cheese
Once cooked, carefully drain any excess liquid from the casserole dish. Top the meatballs with marinara sauce followed by mozzarella and parmesan cheese.
Step 5: Final Bake
Return the casserole to the oven and bake for an additional 10–15 minutes or until the cheese is melted and bubbly. For an extra touch of crispiness, broil for 3–4 minutes at the end while keeping a close eye to avoid burning.

Common Mistakes to Avoid
Avoiding common mistakes can make your Keto Meatball Casserole even better. Here are some pitfalls to watch out for:
-
Skipping the seasoning: Not adding enough herbs and spices can lead to bland meatballs. Always taste your mixture before cooking to ensure it’s flavorful.

Overcrowding the casserole dish: Placing too many meatballs in the dish can prevent even cooking. Make sure there’s space between each meatball for proper heat circulation.
-
Not draining excess liquid: Failing to drain the cooking liquid can result in a watery casserole. Carefully remove any excess liquid before adding sauce and cheese.
-
Ignoring cooking times: Cooking the meatballs for too long can make them dry. Use a meat thermometer to check that they reach an internal temperature of 165°F.

Forgetting to preheat the oven: Baking in a cold oven can affect cooking time and texture. Always preheat your oven before placing your casserole inside.
