Creamy Spinach Garlic Meatballs Stuffed with Mozzarella

Spinach Garlic Meatballs Stuffed with Mozzarella – A High-Protein Comfort Food Dinner

These spinach garlic meatballs stuffed with mozzarella come together in about 35 minutes, making them an easy weeknight dinner that feels anything but ordinary. The outside is golden and slightly crisp, while the inside stays tender with pockets of melted cheese in every bite. I remember making a batch of these on a chilly Tuesday evening in my small kitchen in Portland, and the smell of garlic and simmering marinara filled the whole apartment. It’s one of those meals that proves you don’t need complicated techniques to get impressive results.

Whether you serve them over pasta, tucked into a sub roll, or simply on their own with a side salad, these meatballs deliver on both flavor and protein. They’re the kind of dish that makes everyone at the table ask for seconds.

Why You’ll Love This Recipe

• Hidden mozzarella centers create a gooey surprise in every meatball

• Garlic and Italian seasoning give them a rich, savory taste
• Baking instead of frying keeps them juicy and less messy
• Perfect for meal prep or freezing for later

Ingredients

• 1 lb ground beef (80/20 or 85/15 works well)
• 1 cup fresh spinach, finely chopped
• 3 cloves garlic, minced
• 1/2 cup breadcrumbs (plain or Italian-style)
• 1 large egg
• 1/4 cup grated Parmesan cheese
• 1 tsp salt
• 1/2 tsp black pepper
• 1 tsp Italian seasoning
• 8 oz fresh mozzarella, cut into small cubes (about 1/2-inch pieces)
• 2 tbsp olive oil (for brushing or spraying)

Instructions

• Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper or foil.
• In a large mixing bowl, combine ground beef, chopped spinach, minced garlic, breadcrumbs, egg, Parmesan, salt, pepper, and Italian seasoning. Use your hands to mix gently until everything is evenly incorporated.
• Take about 2 tablespoons of the meat mixture and flatten it in your palm. Place one cube of mozzarella in the center, then fold the meat around it, rolling into a smooth ball. Make sure the cheese is fully sealed inside.
• Place each meatball on the prepared baking sheet, spacing them about an inch apart. Brush or spray lightly with olive oil.
• Bake for 18–22 minutes, or until the meatballs are cooked through and golden brown on the outside. If you want extra browning, switch to broil for the last 2 minutes.
• Let them rest for 3–5 minutes before serving so the cheese sets slightly and doesn’t spill out immediately.

Pro Tips

• Chop the spinach very finely so it blends into the meat mixture without creating chunks that could make the meatballs fall apart.
• If the mixture feels too sticky or wet, add an extra tablespoon of breadcrumbs. If it feels too dry, add a splash of milk or water.
• For the best cheese pull, use fresh mozzarella that’s not too dry. Low-moisture mozzarella won’t melt as nicely inside.
• Don’t overmix the meat. Overworking the mixture can make the meatballs dense and tough instead of tender.
• Use a cookie scoop to portion the meat mixture evenly, which helps them cook at the same rate.

Variations

• Swap ground beef for ground turkey or chicken for a leaner option. Just add a tablespoon of olive oil to keep them moist.
• Add a pinch of red pepper flakes or a dash of cayenne to the meat mixture for a little heat.
• Instead of mozzarella, try stuffing each meatball with a small piece of provolone or smoked gouda for a different flavor.
• Serve with marinara sauce for dipping, or simmer the baked meatballs in your favorite tomato sauce for 10 minutes before serving.

Frequently Asked Questions

• Can I use frozen spinach instead of fresh? Yes, but thaw it completely and squeeze out as much water as possible before chopping. Excess moisture can make the meatballs soggy.
• How do I prevent the cheese from leaking out during baking? Make sure the mozzarella cube is fully surrounded by meat, with no thin spots or gaps. Chilling the formed meatballs in the fridge for 15 minutes before baking also helps.
• Can I make these meatballs ahead of time? Absolutely. You can assemble them up to 24 hours in advance and keep them covered in the fridge. Bake them straight from the fridge, adding a couple of extra minutes to the cooking time.
• How do I reheat leftovers without drying them out? Reheat in a 350°F oven for about 10 minutes, or warm them in a skillet with a splash of marinara sauce to add moisture.
• Can I freeze these meatballs? Yes. Place the baked and cooled meatballs on a baking sheet in the freezer for an hour, then transfer them to a freezer-safe bag. They’ll keep for up to three months. Reheat from frozen in a 375°F oven for about 20 minutes.
• What should I serve with these meatballs? They’re great over spaghetti, on a crusty sub roll with melted provolone, or alongside roasted vegetables and a simple green salad.
