There’s no need to heat up your oven or turn on your stove for these easy and healthy Slow Cooker Mozzarella-Stuffed Meatballs! While this delicious comfort food may look rich and cheesy, it’s actually a clean eating dinner that’s full of protein and vegetables for a nutritious and family-friendly dinner!

I know that it might seem a little bit crazy to be sharing a hearty and cozy meatball recipe in the middle of the summer, BUT…listen up! This is actually a lightened-up recipe that’s perfect for bathing suit season AND the meatballs and the sauce cook entirely in the slow cooker…meaning you don’t even have to heat up your oven on a hot day! Pretty genius, right?

I actually can’t take all of the credit for this particular recipe. A very sweet reader named Julie shared it with me via email a few months ago after creating it for her fiancee. I tweaked Julie’s original recipe to make it even easier (I didn’t want to have to bake the meatballs or turn on a skillet before using the Crock Pot, and I lightened it up with some lean meat and loads of fresh veggies).

How to Stuff the Meatballs with Mozzarella

To stuff the meatballs you need to mix all the ingredients together to make the meatballs apart from the mozzarella. To do this put everything in a bowl and gently massage everything together using your hands.

Pick up a small amount of meatball mixture, flatten in your hand then add a cube of mozzarella and shape the meat around it to create a meatball. Repeat with the rest of the mixture.

Serving Suggestions and Using Leftovers

You’re going to love these meatballs served over pasta or zucchini noodles, or stuffed inside a hoagie roll. My family devoured them when I first served the meal, and we’ve enjoyed the leftovers again from the freezer. That’s right — I got TWO dinners from one effort (eat half now, freeze the other half for later), which is the true definition of efficiency! Thanks to Julie for this wonderful idea!

Ingredients

For the Meatballs:

• 1.5 lb. ground beef I used 93% lean
• 1 large egg beaten
• 2 tablespoons milk
• 2 tablespoons grated Parmesan cheese
• ¾ teaspoon salt
• ¼ teaspoon garlic powder
• ¼ teaspoon pepper
• 2 teaspoons Italian seasoning
• 1 log 8 ounces fresh mozzarella cheese, or if you can find them I like to use the fresh mozzarella snacking cheese balls because they’re already shaped in exactly the right size – it’s an easy shortcut!

For the Sauce:

• 2 carrots grated
• 1 small onion finely chopped
• 1 red bell pepper finely chopped
• 1 8 ounce package sliced mushrooms
• 1 6 ounce can tomato paste
• 1 cup beef broth
• 1 cup marinara sauce homemade or from a jar
• 1 teaspoon salt
• ½ teaspoon oregano
• ½ teaspoon basil

Instructions

1. Place vegetables (carrots, onion, bell pepper, and mushrooms) in bottom of slow cooker.
2. In a large bowl, use hands to gently combine first 8 meatball ingredients (beef through Italian seasoning). Cut mozzarella into small cubes (about ½-inch diameter). Mold meat mixture around each piece of cheese to form round balls.
3. Place raw meatballs on top of vegetables in the slow cooker.
4. In a separate bowl, combine tomato paste, broth, marinara, salt, oregano, and basil. Pour over meatballs.
5. Cover and cook on low for 4-6 hours. Give everything a good stir and serve over pasta, zucchini noodles, or in hoagie rolls!
