But, alas, I’m getting ahead of myself. Let’s start from the beginning – the meatballs. We’re starting with a 400F oven and a baking sheet lined with parchment paper. Then, it’s as simple as mixing all of the ingredients together and rolling them into balls. Place the meatballs on the baking sheet and slide them into the oven for 20 minutes.

While the meatballs are in the oven, add the marinara ingredients to a sauce pan and simmer over low heat for 20 minutes. Stir to mix all of the ingredients together then let it simmer unbothered. You can stir once or twice while it’s simmering, but it’s not necessary.

Before you take the meatballs out of the oven, lightly spray a medium sized baking dish with non-stick cooking spray (or use oil). Spread a light layer of marinara over the bottom of the dish and top with the meatballs.

Ladle marinara over the meatballs, add cheese (mozzarella and ricotta), more sauce, and more cheese. Bake for 20 minutes or until the top is bubbly and golden.


You can serve this dish up as is or with any of the following suggestions for a perfect, wholesome meal.

  • Side Salad – a simple salad is the perfect way to round out this meal. Lettuce, onion, green peppers, and a light vinaigrette dressing. Perfection!
  • Pasta – use zoodles or riced cauliflower as a base for the meatballs. You can, alternatively, use regular pasta if you’re not strictly keto.
  • Sub– meatball subs are capital A amazing so I wouldnt blame or judge you for serving this recipe up in a sub roll. Schmidt’s 647 has long rolls that are only 14 net carbs! A great way to treat yourself if you have room in your macros.

Even if your reader doesn’t follow a specific diet (eg. gluten free), they may have friends or family that they’re cooking for that could use this. This is also a great idea to link out to another blogger with a similar recipe that fits a different diet.

You can simply keep leftovers in the casserole dish and refrigerate them covered for up to 4 days. You can also store individual portions the same way, in covered containers.

If you prefer to make it now and serve it later you can! Just allow it to completely cool, cover with aluminum foil, and freeze for up to 3 months. When you’re ready to serve the keto meatball casserole, bake it in a preheated oven at 350 for 45 minutes.
