How to Make Cheesy Spinach Mozzarella Meatballs
1. Preheat the Oven
Preheat your oven to 400°F (200°C).
Line a large baking sheet with parchment paper or lightly grease a baking dish.
2. Prepare the Spinach
Wash and dry the spinach thoroughly.
Finely chop it.
If using frozen spinach, thaw completely and squeeze out as much moisture as possible.
This is very important because excess water can make the meatball mixture too soft.
3. Prepare the Mozzarella
Cut the mozzarella into small cubes approximately ½ inch wide.
Keep them refrigerated until ready to use.
Cold cheese is easier to seal inside the meatballs.
4. Make the Breadcrumb Mixture
In a large mixing bowl, combine:
- Breadcrumbs
- Milk
Let the mixture sit for approximately 2–3 minutes.
This helps keep the meatballs tender.
5. Add the Egg

6. Add Parmesan
Stir in the Parmesan.

22. Prepare the Marinara
While the meatballs bake, add the marinara sauce to a large skillet or saucepan.

Tips for the Best Cheesy Spinach Mozzarella Meatballs
Remove Moisture from the Spinach
Wet spinach can make the meatballs difficult to shape.
Use Low-Moisture Mozzarella
Fresh mozzarella releases more water and may leak more easily.
Keep the Cheese Cold
Cold mozzarella is easier to seal inside the meat.
Don’t Overmix
Gentle mixing keeps the meatballs tender.
Seal the Cheese Completely
Any exposed mozzarella can melt out during baking.
Use Similar-Sized Meatballs
Uniform meatballs cook at roughly the same rate.
Use a Thermometer
This is the easiest way to avoid overcooking while ensuring safe doneness.
Let Them Rest
The cheese center becomes extremely hot.
