Step‑by‑Step Instructions for Keto Meatball Parmesan Casserole
Step 1: Preheat Your Oven
Begin by preheating your oven to 400°F (200°C). While the oven warms up, line a baking sheet with parchment paper. This will not only prevent sticking but also make cleanup easier later. Ensure that your oven is nicely heated before moving on to preparing your meatballs for the perfect bake.
Step 2: Prepare the Meatball Mixture
In a large mixing bowl, combine the ground turkey with an egg, shredded mozzarella, onion powder, garlic powder, Italian seasoning, and a good pinch of salt. Use your hands to gently mix everything together until just combined, taking care not to overwork the mixture, as you want tender meatballs.
Step 3: Shape and Bake the Meatballs
Now it’s time to form the meatballs! With your hands, scoop out about 1.5 inches of the mixture and roll them into balls. Place each meatball on the prepared baking sheet, ensuring they have space between them. Bake in the preheated oven for 25 minutes, or until they are browned and cooked through.
Step 4: Assemble the Casserole
Once the meatballs have finished baking, remove them from the oven and transfer them into a greased baking dish. Pour the low-carb tomato sauce over the meatballs, ensuring they are nicely coated. Next, sprinkle the remaining shredded mozzarella and all of the grated parmesan on top, layering generously for that cheesy goodness.
Step 5: Bake Until Cheesy and Bubbly
Place the assembled Keto Meatball Parmesan Casserole in the oven and bake uncovered for 15 to 20 minutes. You’ll know it’s ready when the cheese is melted, bubbly, and begins to turn golden. For an extra kick, broil for 2 to 3 minutes until the top is beautifully crisped.
Step 6: Let it Rest and Serve
After baking, it’s crucial to let the casserole rest for about 5 minutes. This allows the flavors to meld. Finally, garnish with fresh basil or parsley before serving hot. Your Keto Meatball Parmesan Casserole is now ready to delight your family!

Make Ahead Options
This Keto Meatball Parmesan Casserole is perfect for busy home cooks who want to save time during the week! You can prepare the meatballs and tomato sauce up to 24 hours in advance; simply store them separately in the refrigerator in airtight containers. To maintain quality, make sure the meatballs are cooked through before refrigerating, as this will help them stay moist. When you’re ready to serve, simply assemble the casserole with the cooked meatballs, pour the sauce over them, top with cheese, and bake according to the final instructions. With this make-ahead plan, you’ll have a comforting, cheesy meal ready to enjoy with minimal last-minute effort!
