Ingredients You’ll Need
These Mozzarella Stuffed Meatballs (low carb, keto) are all about quality ingredients coming together seamlessly. Every item in this lineup adds something special, whether it’s a burst of flavor, a tender bite, or that crave-worthy cheesy core. Here’s what you’ll need and why each ingredient matters:
- Lean ground beef: The base for our tender, protein-packed meatballs – leaner meat helps keep things light while still juicy.
- Italian seasoning: A blend of herbs that infuse every meatball with classic, aromatic flavor.
- Egg: Essential for binding the mixture together so your meatballs hold up beautifully.
- Fresh parsley (finely chopped): Adds a vibrant, fresh color and a pop of herbaceous brightness.
- Salt: Balances and lifts all the other flavors, so don’t skip it!
- Ground black pepper: Adds warmth and just the right amount of kick to the mix.
- Mozzarella cheese (cubed): The star ingredient – these little cubes melt into oozy clouds of deliciousness at the meatball’s heart.
- Olive oil: The foundation for our luscious marinara; use a good quality oil for depth of flavor.
- Onion (finely chopped): Gently sautéed for natural sweetness and body in the sauce.
- Crushed tomatoes (canned): The juicy, tomato-rich base of the marinara that brings everything together.
- Bay leaf: Infuses the sauce with subtle earthiness; you’ll notice the difference.
- Garlic (chopped): Adds boldness and makes the kitchen smell intoxicating.
- Fresh parsley or basil (finely chopped): Sprinkle on top (or in the sauce) for a fresh, herby finish.
- Black pepper: A touch more in the sauce for layered flavor and warmth.
How to Make Mozzarella Stuffed Meatballs (low carb, keto)
Step 1: Prepare the Marinara Sauce
Start by heating a tablespoon of olive oil in a sturdy pan over medium heat. Toss in the finely chopped onion and let it gently sauté until it turns soft and just golden – about five minutes. Now, add in the chopped garlic and stir until fragrant. Pour in the crushed tomatoes along with the bay leaf, black pepper, and a sprinkle of fresh parsley or basil. Let the sauce simmer uncovered over low to medium heat, stirring occasionally, as you move on to the meatballs. The flavors will meld beautifully as it bubbles away for around 20–30 minutes.
Step 2: Mix and Prepare the Meatball Mixture
Set your oven to 400F to preheat while you prepare your baking pan by lining it with parchment paper. In a large mixing bowl, combine the lean ground beef, Italian seasoning, egg, fresh parsley, salt, and ground black pepper. Use your hands or a fork to gently combine everything until it’s just mixed – you want things cohesive but not overworked for the juiciest Mozzarella Stuffed Meatballs (low carb, keto).
Step 3: Stuff and Shape the Meatballs
Take a golf ball sized portion of your beef mixture, then flatten it in your palm. Place a cube of mozzarella cheese right in the center, and wrap the meat around it, pressing gently but firmly to fully enclose the cheese. There’s nothing quite as delightful as discovering gooey mozzarella at the center, so make sure there are no gaps. Repeat until you have about 12 perfectly stuffed meatballs.
Step 4: Bake the Meatballs
Arrange the stuffed meatballs on your prepared sheet pan, leaving a little space between each one. Slide them into the oven and bake for 15–20 minutes. You’ll know they’re ready when they’re golden, sizzling, and just a touch of cheese peeks out. The aroma is going to be irresistible!
Step 5: Serve with Marinara and Garnish
Once done, nestle your fresh-from-the-oven meatballs in a bed of warm homemade marinara sauce. Sprinkle with chopped fresh parsley or basil, and let everyone dig in! It’s classic comfort food made light and vibrant – Mozzarella Stuffed Meatballs (low carb, keto) never disappoint.

Garnishes
Scatter a generous handful of freshly chopped parsley or basil across the top for an uplifting burst of green color and a hint of brightness. A light dusting of grated Parmesan will add even more richness and a little extra decadence. Serving these Mozzarella Stuffed Meatballs (low carb, keto) with a final drizzle of good olive oil can also elevate the flavors right before the meal hits the table.
Side Dishes
If you want a full meal, pair your meatballs with zoodles (zucchini noodles), roasted cauliflower, or a crisp leafy green salad to keep things keto-friendly and balanced. Roasted broccoli or garlic butter green beans also make for perfect partners. For non-keto family members, a warm side of sourdough or garlic bread is a classic touch.
Creative Ways to Present
Skewer each meatball with a toothpick for a party-friendly appetizer or game day treat. Or, present over a bed of spiralized veggies for an impressive, colorful dinner plate. For another twist, serve the Mozzarella Stuffed Meatballs (low carb, keto) in a rustic skillet at the center of the table so everyone can help themselves family-style.
Make Ahead and Storage
Storing Leftovers
Place any leftover meatballs and sauce in an airtight container and refrigerate for up to 3 days. The flavors deepen as they rest, making your lunch or next-day dinner even more mouthwatering. If you like, store the sauce and meatballs separately to maintain the best texture.
Freezing
For longer storage, freeze cooked meatballs (without sauce) on a baking tray, then transfer to a freezer bag or container once solid. You can freeze portions of the marinara separately. Both will keep well for up to 2 months. Thaw overnight in the fridge for the freshest taste.
Reheating
To reheat, simply warm the meatballs gently in a pan with a splash of sauce over medium-low heat until heated through. Alternatively, microwave them covered for a minute or two. If reheating from frozen, allow the meatballs to thaw before warming for best texture and even, cheesy centers.
FAQs
Can I use ground turkey or chicken instead of beef?
Absolutely! Both ground turkey and chicken work beautifully and will lighten up the Mozzarella Stuffed Meatballs (low carb, keto) even further. Just make sure to adjust the seasoning to taste, and try not to overcook, as leaner meats can dry out more easily than beef.
How do I keep the cheese from leaking out?
The secret is to really seal those meatball edges carefully around the mozzarella cube. Wetting your hands a little when forming each one helps create a smooth, sealed surface. Even with perfect sealing, a tiny bit of cheese might escape – just call it a crunchy, golden bonus!
Is there a dairy-free alternative to mozzarella?
Yes, several dairy-free mozzarella-style shreds or cubes melt nicely and can be used as a substitute. Just check that your alternative is low in carbs if you’re keeping strict keto guidelines for your Mozzarella Stuffed Meatballs (low carb, keto).
What can I do if my marinara sauce is too thick or thin?
If your sauce thickens up too much, just stir in a splash or two of water until it reaches your desired consistency. If it feels too thin, let it simmer a bit longer to reduce and intensify the flavors. Taste as you go so every bite is just as vibrant as you like!
Can this recipe be doubled for meal prep?
It absolutely can! Simply double all the ingredients and bake the meatballs in batches if needed. Mozzarella Stuffed Meatballs (low carb, keto) make for fantastic meal prep – just portion everything out for ready-to-go lunches or quick dinners during busy weeks.
