Keto Meatball Casserole is packed with low carb meatballs, sauce, and cheese. Serve with your favorite noodles for a complete meal the whole family is sure to absolutely love.
I wasn’t sure if I was going to share this recipe on the blog or not. It has made a frequent appearance in on my dinner menu over the past few months. It is so delicious, loaded with flavor, and completely low carb.
For this keto meatball casserole, I used my recipe for homemade pasta sauce which cooks up in minutes. The pasta sauce requires a pinch of sugar and you can omit it or use stevia. I have done both with no problem. If you prefer to use pasta sauce from a jar, then that is totally fine as well.
The recipe requires homemade meatballs, but no worries as they are baked in the oven using the same dish that you will use to make the casserole.
What ingredients are needed Meatball Casserole?
- Low carb meatballs
- Easy homemade pasta sauce
- Mozzarella cheese or any your prefer
How to Make the Low Carb Meatball Casserole:
This recipe begins by making the low carb meatballs.
To a large mixing bowl, add in the ground beef, mozzarella, parmesan, egg, chopped onion, garlic powder, Italian seasoning, salt, and ground black pepper.
Stir together using a large spoon on by hand until all of the ingredients are combined and the meat mixture sticks together to form a large ball.
Using a scoop or by hand, form the meatballs any size that you like. Place the meatballs in a casserole dish leaving a small amount of space between each meatball. Basically just make sure they are not touching each other or the side of the dish.
Place in the preheated oven and bake at 400 degrees F. for 15 to 20 minutes depending on the size of your meatballs.
Remove the meatballs from the oven and drain off the excess fat. It may be easier to use a slotted spoon and remove the meatballs and place in a small bowl or dish for a moment. Completely drain the dish of any fat and evenly coat the bottom of the dish with half of the pasta sauce.
Place the meatballs evenly on top of the sauce.
Top the meatballs with the rest of the pasta sauce. Make sure each individual meatball is covered in the pasta sauce. Use a spoon to spread it evenly.
Top the keto meatball casserole with the shredded mozzarella cheese spread out in an even layer.
Place into the oven and bake an additional 10 to 15 minutes, until the cheese is melted and bubbly.
Serve warm on top of your favorite pasta or with a side of your favorite vegetable. If using this as a family meal, I usually serve mine over zucchini noodles and the rest of the family over spaghetti noodles.
Store any leftovers in an airtight container in the refrigerator up to 3 days.

I made this tonight and my oldest boy was visiting and he asked for the recipe! It was that good.
Hi Evie! Glad to hear that you enjoyed this recipe!
I was thinking about putting the meatballs on a rack and baking them that way, elevating them from the grease. Doing it this way would seem to make removing them from the pan easier too. Since what I have is 85/15 ground beef, there will certainly be a lot of grease coming out during the baking time. Your thoughts?
Thanks for the easy and interesting recipe.
Hi Pat! Cooking them that way will be perfectly fine if you feel that will be easier for you 🙂
