Ever see Gordon Ramsey’s Kitchen Nightmares? In one of them, there are twin guys who own a restaurant and stand out the front shouting “HOMEMADE MEATBALLS” to the traffic. I keep hearing those guys in my head when I think about this recipe.
I am always looking to streamline my evenings. Having these in the freezer is fantastic for a quick meal. Throw them in some marinara sauce, cook some pasta and HELLO DINNER!
These are special little meatballs because they are stuffed with cheesy goodness that make them slightly different (and a whole lot yummier) than regular meatball recipes.
You can oven bake them on a baking sheet or cook them in a skillet, making this super convenient!
Try my Instant Pot Meatballs for another way to make these! I hope you love these as much as we do!
Why you’ll love this
- These aren’t your average meatballs! They pack a punch of flavor, and are filled with cheesy goodness.
- These meatballs can be made in bulk and frozen, ready to pull out and cook for a quick dinner.
What to serve with Cheese Stuffed Meatballs
I serve them in a couple of ways. Sometimes as an appetizer, with toothpicks and a bowl of marinara for dipping, and other times thrown in some marinara sauce and tossed with spaghetti.
I also love to use these meatballs in hoagie rolls or subs, and make a yummy lunch!

Key Recipe Ingredients
Note: This highlights some ingredients. Full list is in the recipe card.
- Mozzarella String Cheese. Cut these, and be sure to freeze them. If you don’t they’ll ooze as they cook, and you’ll lose that yummy cheesy bite.
- Ground Beef. For meatballs, you can use a blend of beef and pork, or sausage if you prefer. I like lean ground beef most of the time, but for this, an 80/20 fat ratio will work as well as a 97/3/
- Bread Crumbs. These are regular breadcrumbs. For extra flavor, grab roasted garlic or seasoned breadcrumbs.
- Eggs. Large eggs. Beat them lightly before adding to make it easier to blend in.
- Onion. Dice this finely. You don’t want huge chunks of onion in your meatballs.
- Garlic. I say 4 cloves of garlic. But you know garlic. Measure that with your heart! Garlic powder can also be used.
- Salt & Pepper. This is essential. Start with 1.5 teaspoons of salt and 1 teaspoon of pepper
- Italian Seasoning. Make your own (recipe below) or grab it at the store.
- Olive Oil. Or any oil you prefer for cooking.
- Marinara. Use store bought or homemade marinara sauce.

How to make this recipe
This is a step-by-step photo guide. Full ingredients and instructions are in the printable recipe card below.
JumpGet prepped. Remove mozzarella cheese (string cheese) from wrappers and cut each string into 8 equal sized pieces. Place cheese cubes in a large bowl or 1 freezer bag and freeze until it is time to form meatballs.
Make the meatballs. Using your hands, thoroughly combine all meatball ingredients (beef, breadcrumbs, milk, eggs, onion, garlic, salt, and pepper) in a large bowl.
Shape the meat mixture into 1 inch meatballs, around each piece of cheese. Seal meatballs well to keep the cheese from oozing out.
Cook the meatballs. Heat olive oil in a large skillet over medium-high heat. Cook the meatballs, turning often until they are browned on all sides.
Drain any fat, then add the marinara sauce to the skillet and stir to combine with the meatballs. Simmer, covered with a lid for 8-10 minutes until meatballs are cooked through.
Remove from skillet, allow to cool. Devour.
