Stuffed Meatloaf with Mozzarella

This stuffed meatloaf recipe transforms an everyday comfort food into something extraordinary with its gooey mozzarella center. The technique of rolling the meat around the cheese creates a beautiful spiral pattern when sliced, making this dish as impressive to look at as it is delicious to eat.

I first served this at my daughter's birthday dinner, and now it's become our traditional celebration meal. The look on everyone's face when they cut into it and see that melty cheese pull is worth every minute of preparation.

Ingredients

• Ground beef: 2 pounds 80/20 blend creates the perfect balance of flavor and juiciness
• Breadcrumbs: 1 cup helps bind the mixture while keeping the texture light
• Grated Parmesan cheese: 1/2 cup adds savory depth and umami notes
• Egg: 1 large works as the crucial binder that holds everything together
• Milk: 1/4 cup ensures moisture and tenderness throughout the meatloaf
• Onion: 1 small finely chopped provides natural sweetness and aromatics
• Garlic: 2 cloves minced offers essential flavor foundation
• Italian seasoning: 1 teaspoon brings cohesive herb flavor without buying separate herbs
• Worcestershire sauce: 1 teaspoon contributes that complex savory undertone
• Salt and pepper: to taste proper seasoning is crucial for bringing all flavors together
• Shredded mozzarella cheese: 2 cups look for whole milk mozzarella for the best melt
• Ketchup: 1/2 cup creates a tangy sweet glaze that caramelizes beautifully
• Fresh parsley chopped: brightens the finished dish with color and freshness

Step-by-Step Instructions

Prepare Your Oven:

Preheat to 350°F with the rack positioned in the middle. This moderate temperature allows the meatloaf to cook through evenly without drying out while giving the cheese inside time to melt perfectly.

Create Your Meat Mixture:

Combine ground beef, breadcrumbs, Parmesan, egg, milk, onion, garlic, Italian seasoning, Worcestershire sauce, salt, and pepper in a large bowl. Mix with your hands just until ingredients are incorporated but avoid overworking which can make the meatloaf tough.

Form The Base:

Lay out a large sheet of parchment paper and shape the meat mixture into a rectangle about 9x13 inches and approximately 1 inch thick. Take your time to create even thickness throughout for consistent cooking.

Add The Cheese Filling:

Sprinkle the shredded mozzarella evenly across the meat rectangle leaving a 1/2 inch border around all edges. This border ensures proper sealing when rolled to prevent cheese from leaking out during baking.

Roll The Meatloaf:

Starting from one of the shorter ends, carefully roll the meat mixture using the parchment paper as a guide. Apply gentle pressure to keep the roll tight but not so firm that the cheese squeezes out. Pinch and seal all edges and seams.

Prepare For Baking:

Transfer the meatloaf seam side down to a baking dish or loaf pan. Brush the entire top and sides with ketchup creating an even coating that will caramelize and add flavor during baking.

Bake To Perfection:

Bake in the preheated oven for approximately 1 hour until the internal temperature reaches 160°F. Use a meat thermometer inserted into the meat portion not the cheese to verify doneness.

Rest Before Serving:

Allow the meatloaf to rest for 10 minutes before slicing. This critical step allows the juices to redistribute throughout the meat and helps the meatloaf hold its shape when cut.

My absolute favorite part of this recipe is watching everyone's reaction when they cut into their slice and see that gorgeous cheese pull. My father in law who claims to dislike meatloaf asks for this version specifically at family gatherings now.

Make Ahead Options

This stuffed meatloaf is perfect for meal prep. You can prepare the entire meatloaf up to 24 hours in advance and keep it covered in the refrigerator before baking. Just be sure to add about 10 minutes to the cooking time if baking directly from cold. Alternatively, you can fully bake the meatloaf, cool completely, and freeze in slices for quick individual portions. Simply reheat in the microwave or covered in the oven until warmed through.

Variation Ideas

While the classic mozzarella filling is delicious, this recipe offers endless possibilities for customization. Try provolone or fontina for different melting properties, or add a layer of sautéed spinach and mushrooms between the meat and cheese for added vegetables. For an Italian-inspired version, include sun-dried tomatoes and basil in the filling. Those who enjoy heat might appreciate pepper jack cheese with a layer of roasted poblano peppers. Each variation maintains the wow factor while offering a new flavor profile.

Serving Suggestions

This stuffed meatloaf pairs beautifully with creamy mashed potatoes which complement the texture and help soak up the flavorful juices. For a complete meal, add roasted vegetables like carrots, Brussels sprouts, or green beans. A simple green salad with vinaigrette provides a fresh counterpoint to the richness of the dish. If you're looking for something different, try serving slices over creamy polenta or alongside buttered egg noodles. For leftover meatloaf, nothing beats a sandwich on thick toasted bread with a smear of mayonnaise and some crisp lettuce.
