Mozzarella Stuffed Meatloaf

Mozzarella stuffed meatloaf hides a ribbon of melted cheese in the center of a savory, well seasoned beef loaf.

A sweet and smoky ketchup and barbecue glaze covers the top, and a layer of sharp cheddar melts over it near the end. The loaf serves six and takes about 1 hour 30 minutes from start to finish, including a short rest before slicing.

Why This Mozzarella Stuffed Meatloaf Recipe Works

Slices of fresh mozzarella tucked into a trench down the center melt as the loaf bakes, so each slice opens to a creamy, stretchy middle. Sealing the seam well keeps the cheese inside instead of leaking into the pan.

Garlic powder, Italian seasoning, onion, and green bell pepper give the beef a savory, Italian style flavor. A spoonful of Worcestershire sauce and barbecue sauce in the mix adds depth and a hint of sweetness.

The glaze goes on in two stages, with the cheddar added at the end. That keeps the sugar from burning and gives you a melted, golden cheese topping that bubbles at the edges.

Ingredients for Mozzarella Stuffed Meatloaf

  • 1 1/2 pounds 90 percent lean ground beef
  • 2 large eggs
  • 1 cup plain dry bread crumbs
  • 1/2 cup whole milk
  • 1/4 cup finely chopped yellow onion
  • 1/4 cup finely chopped green bell pepper
  • 2 teaspoons garlic powder
  • 2 teaspoons Italian seasoning
  • 1/2 teaspoon black pepper
  • 1 tablespoon Worcestershire sauce
  • 1 tablespoon honey barbecue sauce
  • 4 oz fresh mozzarella, sliced 1/4 inch thick
  • 4 oz sharp cheddar cheese, shredded (1 cup)
  • 1/2 cup ketchup, for the glaze
  • 1/4 cup packed brown sugar, for the glaze
  • 1/4 cup honey barbecue sauce, for the glaze
  • 1/2 teaspoon garlic powder, for the glaze
  • 1/4 teaspoon black pepper, for the glaze

Fresh mozzarella. Pat the slices dry with paper towels so extra moisture does not escape into the loaf. Slices about 1/4 inch thick melt evenly.

Ground beef. Ninety percent lean keeps the loaf juicy without too much grease pooling around the cheese.

Bread crumbs and milk. Soaking the crumbs in milk creates a soft binder that keeps the loaf tender and sliceable.

Sharp cheddar. The cheddar goes on the top near the end for a golden, bubbly cap that contrasts with the soft center.

How to Make Mozzarella Stuffed Meatloaf

1. Preheat and line. Heat the oven to 350 degrees F and line a rimmed baking sheet with parchment paper.

2. Soak the crumbs. Stir the bread crumbs and milk together in a large bowl and let them stand for 5 minutes.

3. Build the meat mixture. Mix in the eggs, onion, bell pepper, garlic powder, Italian seasoning, pepper, Worcestershire sauce, and 1 tablespoon barbecue sauce. Add the beef and mix gently until just combined.

4. Shape and stuff. Form the mixture into an oval loaf about 10 by 5 inches on the sheet. Press a trench 1 1/2 inches wide down the center, lay in the mozzarella, then fold the meat over and pinch the seam closed.

5. Make the glaze. Stir together the ketchup, brown sugar, 1/4 cup barbecue sauce, 1/2 teaspoon garlic powder, and 1/4 teaspoon pepper.

6. Glaze and bake. Spread about three quarters of the glaze over the loaf and bake for 45 minutes.

7. Add the cheddar. Spread on the remaining glaze, scatter the cheddar on top, and bake 10 to 15 minutes more, until the center reaches 160 degrees F.

8. Rest. Let the loaf rest for 10 minutes so the cheese sets slightly and the slices hold together.

9. Slice. Use a serrated knife and a gentle sawing motion to cut thick slices that show the cheese center.

How to Serve Mozzarella Stuffed Meatloaf

Serve the slices hot with extra glaze spooned over each portion. Good side dishes include easy green bean casserole, air fryer garlic bread slices, air fryer broccoli with Parmesan, and fluffy homemade dinner rolls.

How to Store and Reheat Mozzarella Stuffed Meatloaf

Cool the loaf and refrigerate slices in an airtight container for 3 to 4 days. Reheat in a covered skillet or oven until they reach 165 degrees F. For longer storage, freeze wrapped slices for up to 2 months and thaw them in the refrigerator overnight.

Tips and Variations for Mozzarella Stuffed Meatloaf

Seal the seam well. Pinch the meat firmly around the cheese and smooth it with wet fingers so nothing leaks out.

Leave a border. Keep the mozzarella about 1/2 inch from the ends and edges of the trench.

Use a rimmed pan. Melted cheese or fat can escape, so a rimmed baking sheet keeps your oven clean.

Skip the extra salt. Cheese, ketchup, and barbecue sauce already bring plenty of salt to this loaf.

Try a low moisture cheese. Low moisture mozzarella slices leak less than fresh and still melt well.

Check the temperature. The loaf is done at 160 degrees F in the center, measured away from the cheese pocket.

Add a vegetable. Mix 1/4 cup finely chopped mushrooms into the beef for extra flavor and moisture.

Store it safely. Chill leftovers within 2 hours, and look at the Purdue Extension guide for storing leftovers.
