If you are looking for a new family dinner this Keto Meatball Casserole should be it. Juicy, flavorful meatballs are baked until golden and then covered with tomato sauce and cheese. My low-carb Meatball Parmesan Casserole was a hit with my family and should be a hit with yours.
When I was in college I was still a vegetarian. One of my favorite meals from the dining hall takeout was a vegetarianItalianmeatball parmesan sub. I have no idea what those “meat” balls were made of, and I probably don’t want to know, but it was terrific.
It was smothered in tomato sauce and topped with provolone. I’d look forward to Tuesdays so I could get dining hall take-out and my favorite meatball parmesan sub. Almost fifteen years later that is the only dining hall food I recall and that is my inspiration for my cheesy meatball casserole.

When I was in college I was still a vegetarian. One of my favorite meals from the dining hall takeout was a vegetarianItalianmeatball parmesan sub. I have no idea what those “meat” balls were made of, and I probably don’t want to know, but it was terrific.
It was smothered in tomato sauce and topped with provolone. I’d look forward to Tuesdays so I could get dining hall take-out and my favorite meatball parmesan sub. Almost fifteen years later that is the only dining hall food I recall and that is my inspiration for my cheesy meatball casserole.
This casserole with meatballs was a perfect substitute. I could eat this Italian meatball casserole recipe once a week for the rest of my life and never get sick of it. And my whole family would agree. We enjoy it with a side salad, vegetables, or any of the main low-carb pasta options out there such as palm noodles and zoodles. This easy family dinner is also low-carb, gluten-free, grain-free, and a THM S recipe.
Ingredients
To make this meatball casserole you only need a handful of common ingredients:
Ground Meat– I typically use ground turkey but ground beef, ground pork, or ground chicken work as well.
Ground Sausage– I use sweet Italian sausage but hot Italian sausage is fine or a combination of the two. If you are doing low-carb or keto just watch for added sugar in the sausage.
Egg– The egg is the binder in this in addition to the grated parmesan cheese.
Shredded Zucchini– You can’t taste it and it gives a lot of moisture to the meatballs.
Shredded Mozzarella Cheese– You can also use a blend of Italian cheese.
Keto Marinara Sauce– I like to make my own but any pasta sauce or tomato sauce without added sugar is fine.
Spices– I prefer to use dried onion, garlic, and basil in these. You can use Italian seasoning in place of the basil if you prefer the flavor of that.

How to make a Keto Meatball Casserole
Step One:I just dump all the ingredients in a large mixing bowl and mix it by hand. In the photo above you can see all the different layered ingredients for the low-carb meatballs in my meatball parmesan. For a bowl of raw meat, it looks pretty nice.
Step Two:Next, scoop the meatballs. You should end up with 24 meatballs. Bake in a baking dish coated with cooking spray until they are almost completely cooked. I shoot for 150-155 on my meat thermometer.
Step Three:Top with sauce sprinkle mozzarella cheese on top and finish baking. For the best golden brown cheese on top broil the low-carb meatball casserole for 2-3 minutes, watching it carefully.
Expert Tip – you can make the Italian meatballs ahead of time, cook until fully cooked, and then freeze the cooked meatballs in a freezer bag. Just place the frozen meatballs in the casserole dish, bake until thawed, and then top with the sauce and cheese. This easy prep idea is always a perfect meal on busy weeknights. I don’t meal prep much but I do do this.
Leftovers:Store any leftovers in an airtight container in the fridge for 3-4 days.
Variations
Fresh Basil– If you have fresh basil feel free to mix some into the ground meat mixture, add some to the marinara, or sprinkle on top after baking.
Spices– Swap the dried minced onion and garlic for onion powder and garlic powder, or sub in Italian seasoning.
Common Questions
What should I serve with meatball casserole?
Our family’s favorite way to serve this is on top of zucchini noodles or spaghetti squash. For any non-keto eaters, you can serve with garlic bread or a side of al dente pasta.
Alternatively, you can serve it with a side of roasted broccoli or green beans, or a green salad.
A Cookie Scoop for Meatballs?
Yup! Here the meatballs are after forming them. I use alarge cookie scoopto simplify the process. Since there is no need to get up to your elbows in raw meat this is a great task to get the kids involved in. Mine are pros at scooping low-carb meatballs by now.

Do I Have to use Zucchini?
That hidden zucchini in my juicy meatballs is my sneaky mom’s favorite addition. My kids don’t even notice it’s in there. If you want to hide it you can peel the green skin off first.
If you would like to substitute another veggie for the zucchini I would recommend chopped spinach. You can also just leave the green stuff out and serve this with someCaesar salad, green beans, or roasted broccoli. The low-carb meatball parmesan will still work.
Can I Freeze Keto Meatballs?
Absolutely! This easy meatball recipe also freezes well! Go ahead and make a double batch and then next time you want an easy Meatball Casserole just thaw, dump into the baking dish, and cover with sauce and cheese. Meatball Parmesan in a jiffy!
