How to Make Keto Meatballs in Italian Cheese Tomato Sauce Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 400°F (200°C). This sets the stage for perfect browning and baking, ensuring your meatballs cook evenly with a nice crust and juicy interior.
Step 2: Mix the Meatball Ingredients
In a large mixing bowl, gently combine the ground beef, Italian sausage, eggs, salt, pepper, onion powder, and Parmesan cheese. Be careful not to overwork the mixture — just mix until everything is evenly distributed to keep your meatballs tender.
Step 3: Form and Sear the Meatballs
Shape the mixture into evenly sized meatballs, about the size of a golf ball for consistent cooking. Heat a frying pan over high heat and sear the meatballs on all sides until they develop a rich brown crust. This step locks in the juices and adds incredible flavor.
Step 4: Prepare the Italian Cheese Tomato Sauce
Using the same pan, stir in the tomato paste and let it cook for a minute to deepen its flavor. Then pour in the pizza sauce and sprinkle in the Italian cheese blend. Stir gently to combine all the delicious layers of flavor.
Step 5: Combine Meatballs and Sauce
Return your browned meatballs back into the pan, coating each one in the luscious cheese tomato sauce. This step lets the meatballs soak up the sauce’s flavors as they finish cooking.
Step 6: Bake with Mozzarella Topping
Transfer everything to a baking dish and top with shredded mozzarella cheese. Bake uncovered for about 20 minutes until the meatballs are cooked through and the cheese is bubbling and golden. This finishing touch makes the dish irresistibly cheesy and comforting.
How to Serve Keto Meatballs in Italian Cheese Tomato Sauce Recipe

Garnishes
Adding fresh garnishes like chopped basil or parsley brings a burst of color and freshness that brightens the rich flavors of the meatballs. A sprinkle of extra grated Parmesan just before serving adds a salty, savory touch that complements the dish beautifully.
Side Dishes
Since this is a keto-friendly dish, low-carb sides like cauliflower rice, zucchini noodles, or roasted vegetables make excellent companions. They absorb the sauce perfectly and keep the meal balanced without sacrificing flavor or texture.
Creative Ways to Present
Presentation can turn a simple meal into a special occasion. Try placing meatballs over a bed of creamy mashed cauliflower and drizzle some extra sauce on top. You can also serve them as a hearty appetizer on skewers with mozzarella cubes and fresh herbs for a fancy twist that will wow your guests.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, they keep wonderfully in an airtight container in the refrigerator for up to three days. The flavors develop even more as they rest, making the next meal just as delicious.
Freezing
This recipe is freezer-friendly! Store cooked and cooled meatballs with sauce in a freezer-safe container for up to three months. When you’re ready for a quick meal, simply thaw overnight in the fridge.
Reheating
To reheat, gently warm the meatballs and sauce in a skillet over medium heat, stirring occasionally to evenly heat without drying out. You can also microwave them covered in short intervals, stirring in between for the best texture.
FAQs
Can I use only one type of meat for these keto meatballs?
Absolutely! While the combination of ground beef and Italian sausage brings the best flavor, using just one type like all beef or all sausage will still yield delicious meatballs. Just expect a slight change in richness and spice level.
Is the pizza sauce keto-friendly?
Yes, many pizza sauces are low in carbs, but it’s always a good idea to check the label for added sugars. Choosing a sauce with no added sugars ensures you stay within keto guidelines.
Can I make these meatballs dairy-free?
For a dairy-free version, substitute the Parmesan and mozzarella with dairy-free cheese alternatives. Keep in mind that the texture and flavor will vary slightly but it’ll still be delicious!
What if I don’t have Italian cheese blend? What can I use instead?
You can substitute it with a mix of shredded mozzarella, Parmesan, and provolone cheeses. This blend will mimic the flavor profile and keep your sauce cheesy and flavorful.
Can I bake the meatballs without searing them first?
You can, but searing is highly recommended because it adds wonderful color and locks in the juices, which means more flavorful and moist meatballs overall.
