Ingredients

All you need for this incredible recipe is a handful of fresh ingredients, about 15 minutes of prep time, and a little bit of #meatballmagic! Get ready to assemble your dream dinner:

Ground Chicken or Turkey: This is our lean protein base. It keeps the meatballs lighter while still being hearty and satisfying.
Fresh Spinach: Finely chopped, this adds beautiful color, freshness, and a gentle earthy note, plus a nutritional boost!
Garlic: We’re using a good amount of this to give the meatballs that essential savory, aromatic flavor.
Breadcrumbs: These are key for binding the meat and moisture together, ensuring your meatballs stay tender and don’t dry out.
Grated Parmesan Cheese: Adds a salty, nutty, umami depth that boosts the overall savory profile of the meatball mixture.
Egg: The binding agent! It helps hold all those lovely ingredients together so your meatballs don’t crumble during cooking.
Italian Seasoning: This blend of classic herbs (like basil, oregano, and thyme) infuses the mixture with that comforting, authentic Italian flavor.
Red Pepper Flakes (Optional): Just a pinch adds a lovely, subtle warmth and kick to balance the richness. Feel free to skip it if you prefer no heat!
Salt and Black Pepper: Essential seasonings to enhance all the other flavors and make the dish truly sing.
Small Mozzarella Balls (Bocconcini): The star of the show! These are the little pockets of cheesy goodness that create the “stuffed” surprise.
Olive Oil: Used to sear the meatballs, locking in the flavor and giving them a beautiful, browned crust before they finish baking.
Marinara Sauce: The delicious, warm, and tangy sauce base that everything simmers in. Use your favorite jarred sauce, or try a homemade one!
Fresh Basil Leaves: The perfect, bright, aromatic garnish to finish the dish and make it feel extra special.

How to Make the Spinach Garlic Meatballs Stuffed with Mozzarella

Step 1: Prep the Mixture

Preheat your oven to 375∘F (190∘C) and line a baking sheet with parchment paper for easy cleanup. In a large bowl, combine your ground meat, spinach, minced garlic, breadcrumbs, Parmesan, egg, Italian seasoning, red pepper flakes (if using), salt, and pepper. Use your hands to gently mix everything together until it’s just combined. Don’t overmix!

Step 2: Stuff the Meatballs

Scoop out about 2 tablespoons of the meat mixture and gently flatten it into a disc shape in the palm of your hand. Place one small mozzarella ball right in the center. Carefully wrap the meat mixture around the cheese, pinching the edges closed and rolling it into a perfect sphere. Repeat this process until all of your mixture is used up.

Step 3: Sear for a Golden Crust

Heat the olive oil in a skillet over medium heat. Sear the meatballs for about 2–3 minutes per side. You just want them to get a gorgeous, light golden-brown crust. This step adds a huge depth of flavor!

Step 4: Bake Until Done

Transfer the seared meatballs to your prepared baking sheet and bake them for 12–15 minutes, or until they are fully cooked through and register an internal temperature of 165∘F (74∘C).

Step 5: The Marinara Hug

While the meatballs finish baking, warm up your marinara sauce in a saucepan on the stove. Once the meatballs are cooked, gently place them into the warm sauce and let them simmer for 2–3 minutes. This allows them to soak up all that wonderful sauce flavor.

Step 6: Garnish and Serve

Garnish your beautiful plate of saucy, cheesy meatballs with fresh basil leaves. Serve hot and get ready to enjoy that glorious cheese pull!

Pro Tips for Making the Recipe

Don’t Overmix: Mixing the meatball base too much will make them tough. Stop mixing as soon as the ingredients are just combined—they should be tender and light!
Go for Small Mozzarella: Use bocconcini (the small pearl-sized mozzarella balls) or cut a block of low-moisture mozzarella into small, half-inch cubes. If the cheese piece is too big, it can be hard to seal the meat around it.
Wet Your Hands: If the meat mixture feels sticky, wet your hands slightly before rolling the balls. This prevents the mixture from sticking to your palms and helps you get perfectly smooth, round shapes.
Use Good Marinara: Since the sauce is such a major component, using a high-quality jarred marinara (or your amazing homemade one!) really makes a difference in the final flavor.

How to Serve

These meatballs are incredibly versatile and pair well with just about anything!

Classic Pasta Night: Toss them with your favorite pasta—spaghetti, penne, or fettuccine—for an elevated, cheesy take on pasta and meatballs.
Submarine Sandwich: Place a few meatballs and extra sauce onto a toasted hoagie roll, top with provolone, and bake until melted for the ultimate meatball sub.
Simple Side Dish: Serve them over a bed of fluffy white rice, creamy polenta, or even mashed potatoes.
Crusty Bread: Honestly, serving them straight from the saucepan with a hunk of crusty Italian bread for soaking up that wonderful marinara is one of the best ways to enjoy them!

Make Ahead and Storage

Storing Leftovers

Place any leftover meatballs and sauce in an airtight container and store them in the refrigerator for up to 3 days. They taste just as amazing (if not better!) the next day.

Freezing

You have a couple of options here! You can freeze the cooked meatballs (without the sauce) in a single layer on a baking sheet, then transfer them to a freezer-safe bag for up to 3 months. Or, you can freeze the unbaked meatballs—just thaw them overnight in the fridge before searing and baking as directed.

Reheating

The easiest way to reheat leftovers is to place the meatballs and sauce in a saucepan over low-medium heat until they are warmed through and the cheese is melty again. You can also microwave them in short bursts.

FAQs

Can I use a different kind of ground meat for these meatballs?

Absolutely! While this recipe calls for ground chicken or turkey to keep them light, these meatballs are fantastic with lean ground beef, ground pork, or a mixture of beef and Italian sausage. Keep in mind that red meat has a higher fat content, so you might not need the olive oil for searing (they’ll release their own fat), and the cooking time might need a slight adjustment depending on the meat you choose. Always cook until the internal temperature is 165∘F (74∘C).

How can I prevent the mozzarella cheese from leaking out while they cook?

The key to a perfect cheese pocket is a good seal! When you wrap the meat mixture around the mozzarella ball, make sure you gently pinch and roll the meatball so there are no visible cracks or seams. The cheese should be completely encapsulated. Also, keeping the mozzarella balls well-chilled before stuffing helps them hold their shape better during the searing and baking process.

What is the best way to get all my meatballs the same size?

For uniform size and even cooking, I highly recommend using a standard cookie scoop (about 2 tablespoons size) to portion out your meat mixture before flattening it. This ensures every single meatball is roughly the same weight and size, which is essential for consistent cooking times. Plus, it makes the whole process much faster and less messy!

Can I make these without the marinara sauce?

Yes, you can! These are delicious on their own. If you want to skip the sauce simmer at the end, simply enjoy them straight out of the oven. You can serve them with a dipping sauce like a creamy pesto or garlic aioli, or just enjoy them plain as a perfect little appetizer or snack. They still have all that great flavor and the surprise cheese center!
