Why You’ll Love This Keto Italian Meatballs with Marinara Sauce

These meatballs hit that magical balance of being indulgent and guilt-free. They’re made with simple ingredients, yet the flavor is anything but basic. They’re naturally gluten-free, thanks to the use of almond flour instead of breadcrumbs, and the cheese inside keeps them moist and flavorful. This recipe is perfect for meal prep, freezer-friendly, and pairs with just about any low-carb side.

What Kind of Ground Meat Should I Use?

You can use ground beef, ground pork, or a mix of both for a more traditional Italian flavor. I personally prefer a 50/50 blend of beef and pork to get the best texture—juicy, tender, and full of flavor. Avoid very lean meats; fat brings moisture and richness that make these meatballs truly shine.

Options for Substitutions

• Almond Flour: If you don’t have almond flour, you can use crushed pork rinds as a low-carb binder.
• Cheese: Mozzarella adds that gooey center, but provolone or even cream cheese can be used for a different flavor.
• Fresh Herbs: Don’t worry if you don’t have fresh basil—dried Italian seasoning works well in a pinch.
• Marinara Sauce: A sugar-free store-bought marinara keeps this recipe easy, but homemade keto marinara makes it even better.

Step 1: Prepare the Meatball Mixture

In a large bowl, combine the ground beef and pork, almond flour, grated onion, minced garlic, Parmesan cheese, egg, Italian seasoning, salt, and pepper. Mix gently using your hands or a spatula until everything is just combined. Avoid over-mixing, as that can make the meatballs tough.

---

Step 2: Stuff with Mozzarella

Take a small scoop of the meat mixture and flatten it slightly in your hand. Place a cube of mozzarella cheese in the center and wrap the meat around it, rolling it into a ball. Repeat until all meatballs are formed.

---

Step 3: Brown the Meatballs

Heat olive oil in a large skillet over medium heat. Add the meatballs in batches, making sure not to overcrowd the pan. Brown them on all sides for about 5–7 minutes. They don’t need to be fully cooked at this point—just nicely seared.

---

Step 4: Simmer in Marinara Sauce

Transfer the browned meatballs into a large saucepan or oven-safe dish. Pour in the sugar-free marinara sauce, ensuring all the meatballs are covered. Simmer on low heat for about 25–30 minutes or until fully cooked through.

---

Step 5: Garnish and Serve

Once the meatballs are done, sprinkle with freshly chopped basil and extra Parmesan cheese before serving. You can enjoy them as-is or pair with spiralized zucchini or cauliflower rice for a full keto-friendly meal.

How Long to Prepare the Keto Italian Meatballs with Marinara Sauce

Prep Time: Most of the prep involves mixing and forming the meatballs, which takes about 15–20 minutes. Stuffing the mozzarella inside adds a few extra minutes, but it’s well worth it for that gooey center.

Cook Time: Browning the meatballs in batches takes roughly 10–15 minutes, and simmering them in marinara sauce requires an additional 25–30 minutes. From start to finish, expect the full process to take about 45–60 minutes.

Tips for Perfect Keto Italian Meatballs with Marinara Sauce

• Don’t overmix the meat mixture—gently combining keeps the meatballs tender.
• Use freshly grated Parmesan for the best texture and flavor.
• Chill the meatballs for 10–15 minutes before browning if you have time; it helps them keep their shape.
• Use a cookie scoop to keep the meatballs uniform in size.
• Make sure your marinara sauce is sugar-free to stay keto-compliant.

---

Watch Out for These Mistakes While Cooking

• Overcooking the meatballs: This can dry them out, especially if you’re using leaner meat.
• Not sealing the cheese inside properly: The mozzarella can leak out during cooking.
• Crowding the pan while browning: It causes steaming instead of searing.
• Using marinara with added sugars: Always check the label or make your own.
• Skipping the browning step: Browning adds a deep flavor base that simmering alone can’t provide.
