 Ingredients

For the Meatballs

• 1 lb (450 g) ground beef or ground chicken
• 1 cup fresh spinach, finely chopped
• 3 garlic cloves, minced
• ¼ cup finely grated Parmesan cheese
• 1 large egg
• ¼ cup breadcrumbs
• 1 tsp dried oregano
• ½ tsp Italian seasoning
• ½ tsp paprika
• ½ tsp salt
• ¼ tsp black pepper
• 1 tbsp olive oil, if needed

Optional Filling

For an extra cheesy centre, add:

• ½ cup shredded mozzarella or small mozzarella cubes

Optional Garnish

• Fresh parsley
• Grated Parmesan
• Red pepper flakes
• Fresh lemon wedges

 How to Make Spinach Garlic Stuffed Meatballs

Step 1: Prepare the Spinach

Wash the fresh spinach thoroughly and pat it dry.

Finely chop the spinach into small pieces.

Place a skillet over medium heat and add a small drizzle of olive oil. Add the minced garlic and cook for approximately 30 seconds, just until fragrant.

Add the chopped spinach and cook for 1–2 minutes, stirring frequently, until wilted.

Remove from the heat and allow the spinach mixture to cool.

Tip: Don’t leave excess liquid in the spinach. If it releases a lot of moisture, gently squeeze or drain it before using. This helps prevent watery meatballs.

Step 2: Prepare the Meat Mixture

Place the ground beef or chicken into a large bowl.

Add:

• Egg
• Breadcrumbs
• Parmesan
• Oregano
• Italian seasoning
• Paprika
• Salt
• Black pepper

Add the cooled spinach and garlic mixture.

Using clean hands or a wooden spoon, gently mix until everything is evenly combined.

Don’t overmix. Overworking the meat can make your meatballs dense and tough.

 Step 3: Add the Filling

If you’re using mozzarella, cut it into several small cubes.

Take approximately 2 tablespoons of meat mixture and flatten it gently in your palm.

Place a small piece of mozzarella in the centre.

Carefully wrap the meat around the cheese and roll into a ball.

Make sure the filling is completely enclosed.

Repeat with the remaining mixture.

If you’re skipping the cheese, simply shape the meat mixture into evenly sized balls.

 Step 4: Bake

Preheat your oven to 400°F (200°C).

Line a baking sheet with parchment paper or lightly grease it.

Arrange the meatballs in a single layer, leaving a little space between each one.

Bake for approximately 20–25 minutes, depending on their size and whether you’re using beef or chicken.

For food safety, ground meat should reach a safe internal temperature. For ground beef, the USDA recommends 160°F (71°C); ground chicken should reach 165°F (74°C).

For an extra browned exterior, place the meatballs under the broiler for the final 1–2 minutes, watching them carefully.

 Step 5: Rest & Serve

Remove the meatballs from the oven and let them rest for approximately 5 minutes before serving.

Garnish with fresh parsley, Parmesan, and a pinch of red pepper flakes.

Serve warm with your favourite sides.

 Recipe Notes

Beef or chicken?

Ground beef creates richer, juicier meatballs with a deeper flavour.

Ground chicken produces a lighter meatball and works especially well with garlic, spinach, Parmesan, and herbs.

Choose whichever fits your preference.

Don’t skip the spinach preparation

Raw spinach contains a lot of water. Quickly wilting it first helps remove some moisture and concentrates its flavour.

Keep the filling small

If you’re using mozzarella, don’t add too much to each meatball. Excess cheese can break through the meat while cooking.

Seal the meatballs well

Make sure there are no cracks around the filling. This helps keep the cheese inside as it melts.

Don’t overmix

Mix just until the ingredients are combined. Overmixing can result in firm, chewy meatballs.

 Tips for Perfect Stuffed Meatballs

1. Keep your meat cold.
Cold meat is easier to shape and handle.

2. Wet your hands slightly.
This prevents the mixture from sticking to your fingers while forming the meatballs.

3. Make them similar in size.
Uniform meatballs cook more evenly.

4. Don’t overcrowd the baking sheet.
Leave space between each meatball so hot air can circulate.

5. Use a meat thermometer.
This is the most reliable way to determine whether the meatballs are safely cooked.

6. Let them rest.
A few minutes of resting helps retain their juices.

7. Add lemon at the end.
A small squeeze of fresh lemon can brighten the rich beef, garlic, and Parmesan flavours.

Storage & Meal Prep

These meatballs are excellent for meal prep.

Refrigerator

Place cooled meatballs in an airtight container and refrigerate for up to 3–4 days.

Freezer

Allow the cooked meatballs to cool completely.

Arrange them on a baking sheet and freeze until firm. Transfer them to a freezer-safe container or bag.

They can be stored frozen for approximately 2–3 months for best quality.

Thaw overnight in the refrigerator before reheating.

Reheating

Reheat in the oven, air fryer, or microwave until heated through.

If reheating in the oven, covering them loosely with foil can help prevent them from drying out.

 Approximate Nutritional Information

Nutrition depends on whether you use beef or chicken; the fat percentage of the meat; the amount of Parmesan, breadcrumbs, and whether mozzarella is included.

For approximately ¼ of the recipe without optional mozzarella, estimated nutrition is the following:

• Calories: 300–350
• Protein: 30–35 g
• Carbohydrates: 8–10 g
• Fat: 16–20 g
• Fiber: 1–2 g
• Sugar: 1–2 g
• Sodium: 500–650 mg

Using lean ground chicken can reduce the fat and calorie content.

Adding mozzarella will increase the calories and fat while also adding some protein and calcium.

 Potential Benefits

High in Protein

Ground meat provides a substantial amount of complete protein, while Parmesan and egg contribute additional protein.

This makes these meatballs a satisfying option for a protein-focused meal.

Contains Spinach

Spinach provides nutrients such as folate, vitamin K, vitamin A, and vitamin C, along with antioxidants.

Adding vegetables directly into meatballs is also an easy way to increase your vegetable intake.

Garlic Adds Flavor

Garlic provides intense flavour without requiring a heavy sauce or large amount of added ingredients.

Flexible Meal

You can serve these meatballs with vegetables for a lighter meal or with pasta, pita, or rice for a more substantial dinner.

Meal-Prep Friendly

Because they refrigerate and freeze well, you can make a large batch and have convenient protein ready for several meals.

 Frequently Asked Questions

Can I use ground chicken instead of beef?

Absolutely. Ground chicken works beautifully in this recipe. Because chicken is generally leaner than beef, be careful not to overcook the meatballs so they remain juicy.

Can I make these without cheese?

Yes. Simply omit the Parmesan and mozzarella. You can add extra herbs or spices for flavour.

Can I use frozen spinach?

Yes. Thaw it completely and squeeze out as much excess water as possible before mixing it into the meat.

Can I make them gluten-free?

Yes. Use gluten-free breadcrumbs or substitute a suitable gluten-free binder.

Can I air fry the meatballs?

Yes. Air fry at approximately 375°F (190°C) until cooked through, usually around 12–16 minutes, depending on size. Check the internal temperature rather than relying only on cooking time.

Why are my meatballs falling apart?

This can happen if the mixture contains too much moisture or doesn’t have enough binder. Make sure the spinach is well drained and that you include the egg and breadcrumbs.

Why did the cheese leak out?

The meat may not have completely sealed around the filling, or too much cheese may have been added. Use small cheese cubes and carefully seal every opening.

Can I prepare the meatballs ahead of time?

Yes. Shape the uncooked meatballs and refrigerate them covered for several hours before baking.

What sauce goes best with them?

Marinara, tzatziki, garlic yoghurt sauce, or a simple lemon-herb sauce all work wonderfully.

Are they good for meal prep?

Definitely. They can be refrigerated for several days or frozen for longer storage, making them a convenient protein option.
