This is one of the best Keto recipes for those who enjoy traditional Italian food. These mozzarella-stuffed meatballs with delicious homemade tomato sauce are an excellent meal for the entire family, whether on Keto or not. We served these flavorsome meatballs over zucchini noodles, but you can substitute them with your favorite low-carb noodles or other sides of your choice (you will find plenty of great ideas in our side section). You can serve the meatballs with some freshly shredded parmesan on top and garnish everything with freshly chopped parsley. These Keto Italian mozzarella stuffed meatballs are best when served while still fresh and warm. Enjoy!

How to Make It

Step 1

Peel and finely chop the onion. Heat one tablespoon of olive oil in a large pan over medium heat. Add onions and cook for 5 minutes, stirring occasionally.

Step 2

Add the tomatoes, salt, basil, sweetener (optional), oregano, garlic powder, and broth. Stir well to combine. Cook for 15 minutes over medium-low heat.

Step 3

Transfer the sauce to a small food processor. Process until completely smooth. Return to the pan and set it aside.

Step 4

Add the ground beef, Italian seasoning, egg, parsley, and black pepper to a bowl. Mix to combine. Optionally, add more Italian seasoning to taste.

Step 5

Preheat the oven to 200°C (400°F). Cut the mozzarella into small cubes. Line a baking tray with parchment paper. Take a golf ball-sized piece of the meat mixture and place a cut piece of mozzarella in the middle. Form a meatball around the cheese and place it on the prepared baking tray.

Step 6

Bake for 15-20 minutes or until fully cooked through. When done, remove from the oven and transfer the balls to the pan with the tomato sauce. Coat the meatballs with the sauce and set it aside.

Step 7

Melt two tablespoons of butter in a large pan over medium heat. Peel and finely chop the garlic. Add to the pan and cook for 2-3 minutes.

Step 8

Spiralize the zucchini. Add the zucchini noodles to the pan and season with salt. Cook for 5-7 minutes over medium-high heat.

Step 9

Serve the meatballs over the zucchini noodles. Optionally, top with some freshly grated parmesan and finely chopped parsley. Enjoy!
