This hearty spinach garlic meatball recipe has become my family's favorite weeknight dinner solution when we want something comforting yet still packed with nutrition. The combination of tender beef, fresh spinach, and that surprise of gooey mozzarella in the center creates a truly memorable mouthful that satisfies both adults and kids alike.
I first developed this recipe during a particularly busy month when I needed to sneak more vegetables into my children's meals. What started as a stealth nutrition mission has turned into the most requested dinner in our household, especially on chilly evenings.
Ingredients
- Ground beef: preferably 90% lean for the perfect balance of flavor and texture while minimizing excess grease
- Fresh spinach: finely chopped to incorporate seamlessly into the meat mixture while adding gorgeous color and nutrients
- Garlic cloves: freshly minced for that aromatic punch that enhances the savory profile
- Breadcrumbs: creating the perfect binding agent while adding a pleasant texture to each bite
- Mozzarella cheese: preferably low moisture for that perfect melt without making the meatballs soggy
- Egg: the essential ingredient that holds everything together during cooking
- Salt and pepper: simple seasonings that allow the main ingredients to shine
Step-by-Step Instructions
- Preheat Oven:
- Set your oven to 400°F and line a baking sheet with parchment paper. This temperature creates that perfect balance of browning the outside while thoroughly cooking the inside. The parchment prevents sticking and makes cleanup a breeze.
- Mix Ingredients:
- In a large bowl combine the ground beef, chopped spinach, minced garlic, breadcrumbs, egg, salt and pepper. Use your hands to mix everything gently but thoroughly. Overmixing can make the meatballs tough, so stop once everything is evenly incorporated. The mixture should hold together when squeezed but still feel somewhat light.
- Form Meatballs:
- Take about two tablespoons of the meat mixture and flatten it slightly in your palm. Place a small cube of mozzarella in the center, then fold the meat around it, sealing completely. Roll between your palms to form a perfect sphere, ensuring no cheese is visible. Place them on the prepared baking sheet with about an inch between each meatball.
- Bake to Perfection:
- Slide the baking sheet into your preheated oven and bake for 20 to 25 minutes. Look for a nicely browned exterior and ensure the internal temperature reaches 165°F. The cheese inside will be perfectly molten at this point. Let them rest for about 5 minutes after removing from the oven to allow the juices to redistribute.

The first time I served these meatballs to my Italian grandmother, she raised an eyebrow at the addition of spinach. By her second bite, she was asking for my recipe. That moment sealed these meatballs as a new family tradition, blending innovation with comfort food classics.
Make Ahead Options
These meatballs work beautifully as a meal prep option. You can form the raw meatballs and refrigerate them for up to 24 hours before baking. If you prefer to work even further ahead, arrange the formed meatballs on a baking sheet and freeze until solid. Transfer to a freezer bag and store for up to 3 months. When ready to cook, simply add about 5 minutes to the baking time when cooking from frozen. This approach has saved countless weeknight dinners at my house when time is short but appetites are large.
Serving Suggestions
While these meatballs are certainly delicious on their own, they truly shine when paired thoughtfully. Serve them atop a bed of spaghetti with marinara sauce for a classic approach, or nestle them into hoagie rolls with melted provolone for incredible meatball subs. For a lower carb option, serve alongside roasted vegetables or on a bed of zucchini noodles. At parties, I often serve them with toothpicks and a side of warm marinara dipping sauce as an appetizer that disappears within minutes.
Flavor Variations
The basic recipe provides an excellent canvas for creative flavor adaptations. For a Mediterranean twist, add 1/4 cup of finely chopped kalamata olives and 2 tablespoons of crumbled feta to the meat mixture. For an Asian inspired variation, replace the Italian seasonings with 1 tablespoon of grated ginger, 2 tablespoons of chopped green onions, and a splash of soy sauce. The cheese center can also be varied according to your preference. Sharp cheddar creates a more pronounced flavor profile, while cream cheese offers a tangy richness that pairs beautifully with the spinach.
