How to Make Spinach Meatballs with Mozzarella

Making these meatballs is a fun and straightforward process. You start by mixing your ground meat with chopped spinach, breadcrumbs, and seasonings. The key is to handle the meat gently so the meatballs stay tender. Once the mixture is ready, you scoop out a small portion, flatten it in your palm, and tuck a cube of mozzarella right in the middle. You then roll it back into a ball, ensuring the cheese is completely sealed inside. After a quick bake in the oven, you have golden-brown meatballs with a surprise cheesy center.

Ingredients

• 1 lb (450g) lean ground beef
• 1 cup fresh spinach, very finely chopped
• 1/2 cup plain breadcrumbs
• 1/4 cup grated Parmesan cheese
• 1 large egg, lightly beaten
• 2 cloves garlic, minced
• 1 teaspoon dried oregano
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 4 oz (115g) mozzarella cheese, cut into 1/2-inch cubes
• 1 tablespoon olive oil (optional for browning)

Directions

1. Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper or lightly grease it with oil.
2. In a large mixing bowl, combine the ground beef, finely chopped spinach, breadcrumbs, Parmesan cheese, beaten egg, minced garlic, oregano, salt, and pepper.
3. Use your hands to gently mix all the ingredients until they are just combined. Do not overwork the meat, as this can make the meatballs tough.
4. Scoop about 2 tablespoons of the meat mixture and flatten it into a small disc in the palm of your hand.
5. Place one cube of mozzarella cheese in the center of the meat disc.
6. Fold the meat around the cheese and roll it between your palms to form a smooth ball. Make sure there are no cracks where the cheese can leak out.
7. Repeat this process with the remaining meat and cheese, placing the meatballs about an inch apart on the prepared baking sheet.
8. Optional: Lightly brush the tops of the meatballs with olive oil for a crispier exterior.
9. Bake for 18 to 22 minutes, or until the meatballs are browned on the outside and cooked through to an internal temperature of 160°F (71°C).
10. Remove from the oven and let them rest for 5 minutes before serving to let the cheese settle.

How to Serve Spinach Meatballs with Mozzarella

These meatballs are incredibly flexible when it comes to serving. For a classic meal, toss them with your favorite marinara sauce and serve them over a bed of spaghetti or zucchini noodles. If you want something more casual, tuck them into a toasted hoagie roll with extra sauce for a delicious meatball sub. They also work wonderfully as an appetizer; simply serve them on a platter with toothpicks and a side of warm dipping sauce. For a lighter dinner, serve them alongside a crisp Caesar salad or roasted Mediterranean vegetables.

How to Store Spinach Meatballs with Mozzarella

If you have leftovers, you can store them in an airtight container in the refrigerator for up to 4 days. To reheat, place them in the microwave for a minute or warm them in a pan with a little bit of sauce until the cheese in the middle is melted again. You can also freeze these meatballs! To freeze, place the cooked and cooled meatballs on a tray in the freezer for an hour, then transfer them to a freezer-safe bag. They will stay fresh for up to 3 months. Thaw them in the fridge overnight before reheating.

Expert Tips for Perfect Spinach Meatballs with Mozzarella

To get the best results, make sure your spinach is as dry as possible. If you use frozen spinach, thaw it and squeeze out every drop of water using a kitchen towel. This prevents the meatballs from becoming soggy. When forming the balls, dampening your hands slightly with water can prevent the meat from sticking to your skin. Also, try to cut your mozzarella cubes into uniform sizes so that each meatball cooks evenly and has the same amount of cheesy goodness. Finally, using a meat thermometer is the best way to ensure they are juicy and safe to eat without overcooking them.

Delicious Variations

You can easily customize this recipe to suit your taste. For a lighter version, replace the ground beef with ground turkey or ground chicken. If you like a bit of heat, add a pinch of red pepper flakes to the meat mixture. You can also swap the mozzarella for other cheeses like provolone or a small piece of sharp cheddar for a different flavor profile. If you want more herbs, fresh basil or parsley can be used instead of or in addition to the dried oregano. For a gluten-free version, simply use gluten-free breadcrumbs or almond meal.

Frequently Asked Questions

1. Can I use frozen spinach instead of fresh?
Yes, you can. Just make sure to thaw it completely and squeeze out all the excess moisture so the meatballs don’t fall apart.

2. Why did my cheese leak out during baking?
This usually happens if the meat isn’t wrapped tightly around the cheese or if there is a small crack. Make sure to roll the meatballs smoothly.

3. Can I pan-fry these instead of baking?
Yes, you can sear them in a skillet over medium heat with a little oil. Be careful when turning them so they stay intact.

4. What is the best fat percentage for the ground beef?
An 85/15 or 90/10 lean-to-fat ratio works best. It provides enough fat for moisture without making the meatballs too greasy.

5. Can I make these without eggs?
You can use a “flax egg” or 2 tablespoons of plain yogurt as a binder if you need an egg-free option.

6. How do I know when the meatballs are done?
The outside should be browned, and the internal temperature should reach 160°F (71°C) on a meat thermometer.

7. Can I prepare these in advance?
Yes, you can roll the meatballs and keep them covered in the fridge for up to 24 hours before baking.

8. Do I have to use breadcrumbs?
Breadcrumbs help hold the moisture in. If you don’t have any, you can use crushed crackers or rolled oats.

9. Can I use a different type of cheese?
Absolutely. Any semi-soft cheese that melts well, like Monterey Jack or Havarti, will work beautifully.

10. Can I cook these in an air fryer?
Yes! Air fry them at 375°F (190°C) for about 12-15 minutes, shaking the basket halfway through.
