This keto chicken meatball casserole is an easy family dish and a great comfort food dish too.   Zucchini is added to the chicken meatballs for extra vegetables and keeps the meat moist.

Only a few ingredients are needed to make this delicious keto chicken meatball casserole. Nothing complicated and you may already have everything in your fridge ready to cook. It’s as simple as ground chicken, zucchini, marinara sauce and cheese!

I love how simple this dish is to make yet and it’s always a crowd pleaser. The Chief Taster has been enjoying this currently with turkey and even took leftovers for lunch the next day. Can it be frozen? I would say so but due to the great flavours of this dish, I’m yet to have enough leftover to try. Perhaps I will bake double the amount the next time I bake it and try freezing it. I need more ready-made dishes in the freezer for when it’s too hot to cook here.

This recipe uses my chicken zucchini meatballs recipe, slathers them with a sugar free marinara sauce, then covers the meatballs with Parmesan and mozzarella cheese.

Ground chicken was used for this meatball casserole, but ground beef, turkey or pork would work just as well. Perhaps a mix of them all for a meat feast meatball!

The zucchini can be optional. It does keep the meat moist without adding any strong flavours and it a great way to sneak a vegetable into your food. Placing all the ingredients into a food processor would give a smoother mixture and hide the zucchini even further! It may be a bit sticky to remove from the machine though.


Serve this keto chicken meatball casserole with zucchini noodle or a side salad. Perhaps a few low carb garlic bread rolls too.


You need the chicken meatballs to be as even as you can make them. I make mine by hand but if you have a cookie scooper that would ensure an identical size.

After you have cooked the meatballs in the oven, drain off any excess liquid. The fatty content of the meat may vary and the zucchini will kick out a drop of water too. You want the meatballs to be moist but not swimming in their own juices.

Serve with fresh basil scattered over the casserole for an extra fresh flavour. It can give an extra flavour and who can resist the smell of fresh basil?

    Didn’t you mean to say, “Place the meatballs in a casserole dish” after draining any excess juice?
