Cheesy Spinach-Stuffed Meatballs

You know those nights when you crave comfort food but also want to feel a tiny bit virtuous? I got you. I discovered these Cheesy Spinach-Stuffed Meatballs when I tried to hide greens inside something that my picky roommate actually liked. Spoiler: it worked, and nobody had to know about the spinach (until the compliments started rolling in).

I’ll walk you through the easy ingredients, the simple steps, and a few pro tips so your meatballs turn out juicy, cheesy, and just the right amount of fancy without any drama. Want a killer sidekick? I love pairing them with a slice of crispy cheesy garlic Parmesan focaccia — try it, you’ll thank me later. Ever tried a meatball that made you do a happy dance? This one will.

Why You’ll Love This Recipe

• Fast weeknight win: You finish these in under an hour from start to table.
• Sneaky greens: The spinach melts into the meat, so even spinach skeptics bite willingly.
• Cheese pull guaranteed: The shredded mozzarella creates little molten centers that make people quiet down and focus—seriously.
• Versatile: Serve them as an appetizer, tuck them in a sub, or float them in marinara for a cozy dinner.
• Kid-friendly: My nephew ate three and then asked for seconds like it wasn’t staged. FYI, bribery by cheese works every time.

Ingredients You’ll Need

• 1 pound ground beef
• 1 cup fresh spinach, chopped
• 1 cup mozzarella cheese, shredded
• 1/2 cup breadcrumbs
• 1/4 cup grated Parmesan cheese
• 1 egg
• 2 cloves garlic, minced
• 1 teaspoon onion powder
• 1 teaspoon Italian seasoning
• Salt and pepper to taste
• Marinara sauce (for serving)

I keep these ingredients simple because I love recipes that don’t require a scavenger hunt through the spice rack.

How to Make (Step-by-Step)

STEP 1

Preheat your oven to 375°F (190°C). Get your baking sheet ready with parchment or a light spray of oil so nothing sticks.

STEP 2

In a large bowl, combine ground beef, chopped spinach, shredded mozzarella, breadcrumbs, Parmesan, egg, minced garlic, onion powder, Italian seasoning, salt, and pepper. Mix until the mixture feels evenly combined but not overworked. Overmixing makes meatballs tough, and we don’t do tough here.

STEP 3

Form the mixture into golf ball-sized meatballs and place them on the baking sheet. Try to keep them roughly the same size so they cook evenly.

STEP 4

Bake in the preheated oven for 25–30 minutes, until the meatballs cook through and brown on the outside. If you want extra color, broil them for 1–2 minutes at the end, but watch closely so they don’t burn.

STEP 5

Serve with marinara sauce. I spoon sauce over them and add extra shredded cheese because I have no shame. Enjoy hot.

Pro Tips for the Best Results

• Chill the mixture for 10 minutes before forming meatballs if your kitchen runs warm. The mixture holds together better.
• Don’t over-handle the meat. Mix until combined, then stop. Gentle hands make tender meatballs.
• Use fresh spinach if you can. It brightens the flavor. If you only have frozen, squeeze it dry and roughly chop.
• Test-cook one meatball in a skillet to check seasoning before baking the whole batch. I do this more often than I admit.
• For extra juiciness, add a tablespoon of milk or a splash of olive oil to the mix.
• Make-ahead: You can freeze formed meatballs on a tray, then bag them. Bake from frozen by adding 10–15 minutes to the cook time.

Fun Variations & Topping Ideas

Variations:

• Add ground pork or turkey instead of beef for a different flavor profile.
• Mix in ricotta (a couple of tablespoons) for creamier meatballs.
• Swap mozzarella for fontina or provolone for a richer taste.
• Make a low-carb version by swapping breadcrumbs for almond flour. IMO, it still hits that comfort-food spot.

Toppings:

• Fresh basil and a drizzle of olive oil.
• A spoonful of pesto for herb-forward flair.
• Red pepper flakes if you like a kick.
• A shower of extra Parmesan because cheese + cheese = happiness.

If you want a fun twist, try rolling these into a cozy sandwich with marinara and provolone. Or lay them over a bed of pasta and pretend you made something fancy. Want more wild combos? I tried them on a pizza crust once and yes, chaos ensued—in the best way.

That onion-ring pizza-style idea pairs surprisingly well if you like loud, joyful food.

Storing and Reheating

Store cooled meatballs in an airtight container in the refrigerator for 3–4 days. Freeze them flat on a tray for 1–2 hours, then move them to a freezer bag for up to 3 months.

To reheat:

• Oven: Place meatballs in a baking dish, splash a little water or sauce, cover with foil, and bake at 350°F (175°C) for 10–15 minutes. They heat evenly and stay juicy.
• Microwave: Heat individual portions for 1–2 minutes, stirring halfway through. The microwave will work when you need food now, not when you have patience.
• Stovetop: Simmer gently in marinara for 8–10 minutes until heated through. This method rehydrates and tastes fresh.

Leftover ideas

• Toss meatballs with pasta and extra marinara for a classic dinner.
• Make meatball sliders with mini rolls and an extra hit of cheese.
• Slice them and top a salad for protein-forward lunch.
• Use sliced meatballs on a homemade pizza or flatbread for instant satisfaction.

Leftovers should feel like a second chance at happiness. Treat them well.

Frequently Asked Questions (FAQ)

How can I make these meatballs gluten-free?

Swap the breadcrumbs for gluten-free breadcrumbs or crushed gluten-free crackers. You can also use almond flour for a low-carb version.

Can I use frozen spinach instead of fresh?

Yes. Thaw frozen spinach, squeeze out all excess water, and then chop. Waterlogged spinach will dilute flavor and make the mixture soggy.

How do I prevent the cheese from leaking out?

Use shredded mozzarella mixed into the meat rather than large cubes. The cheese blends into the meat and creates pockets rather than a molten explosion. If you love dramatic cheese pulls, use a mix of shredded and small cubes.

Can I make these ahead and freeze them?

Absolutely. Freeze unbaked meatballs on a tray, then transfer them to a bag. Bake from frozen by adding 10–15 minutes to the original time.

What’s the best sauce to use?

Marinara works perfectly. You can also use spicy arrabbiata for heat or a creamy tomato sauce for something richer.
