Step-by-Step Instructions

Preparing the Meat Mixture

Begin by preheating your oven to 350°F (175°C) and lining a baking sheet with foil or parchment paper, or preparing a loaf pan with cooking spray. This preparation ensures easy cleanup and prevents sticking.

In a large skillet over medium heat, add 1 tablespoon of olive oil. Once hot, add 1 cup of finely diced onion and sauté until translucent, about 3-4 minutes. Add 3 minced garlic cloves and cook for an additional 30 seconds until fragrant, being careful not to burn the garlic. Set aside to cool slightly. Cooking the onions and garlic before adding to the meat mixture mellows their raw bite and adds deeper flavor.

In a large mixing bowl, combine 1.5 pounds of ground beef (80/20 lean-to-fat ratio) and 1/2 pound of ground pork. Using a blend of meats creates more complex flavor and better texture than using just one type of meat.

Add 2 lightly beaten eggs, 3/4 cup breadcrumbs, 1/4 cup milk, 2 tablespoons Worcestershire sauce, 1 tablespoon Italian seasoning, 1.5 teaspoons salt, 1/2 teaspoon black pepper, and 1/4 cup chopped fresh parsley to the meat.

Add the cooled onion and garlic mixture to the bowl. Using clean hands, gently mix all ingredients until just combined. Overmixing can make the meatloaf tough, so stop as soon as the ingredients are evenly distributed.

For the best flavor development, allow the mixed meat to rest in the refrigerator for 30 minutes, though this step is optional if you’re short on time.

Creating the Cheese Filling

While the meat mixture rests, prepare the cheese filling. Cut 8 ounces of mozzarella cheese into approximately 1/2-inch thick slices or sticks, depending on your preference for the shape of the cheese center. If using cheese slices, stack them to create a log shape that will run through the center of the meatloaf.

For enhanced flavor, mix 1/4 cup grated Parmesan cheese with 1 teaspoon Italian herbs and sprinkle over the mozzarella. This step is optional but adds another dimension of flavor to the melted cheese center.

For easier handling, chill the prepared cheese in the refrigerator until ready to use. Cold cheese will be less likely to leak out during the shaping process.

Assembling the Meatloaf

Remove the meat mixture from the refrigerator if chilled. On a piece of parchment paper or a clean work surface, form the meat mixture into a rough rectangle approximately 9 x 12 inches and about 1/2-inch thick. Try to keep the thickness even throughout for consistent cooking.

Place the prepared cheese down the center of the meat rectangle, leaving at least 1.5 inches of meat mixture on all sides. The cheese should run along the length of the rectangle.

Using the parchment paper to assist, carefully lift one long side of the meat rectangle and fold it over the cheese. Repeat with the other side, creating a seam at the top. Seal the edges and ends well to prevent cheese from leaking during baking. This is crucial for creating that perfect melted center reveal when sliced.

Carefully transfer the meatloaf to the prepared baking sheet or loaf pan, positioning it seam-side down. Shape the loaf as needed to create an even, attractive form. If using a baking sheet rather than a loaf pan, the meatloaf will have a more artisanal appearance with nicely browned edges.

Making the Sauce

In a small bowl, combine 3/4 cup ketchup, 2 tablespoons brown sugar, 1 tablespoon Worcestershire sauce, 1 tablespoon Dijon mustard, 1/2 teaspoon garlic powder, 1/2 teaspoon smoked paprika, and 1 tablespoon balsamic vinegar. Whisk until smooth and well combined.

Reserve about 1/3 of the sauce for serving. Spread the remaining sauce evenly over the top and sides of the meatloaf. The sauce creates a tangy, flavorful glaze that will caramelize beautifully during baking.

Baking the Meatloaf

Insert a meat thermometer into the meatloaf (avoiding the cheese center) if you have one. This helps ensure the meat reaches the proper temperature without overcooking.

Bake the meatloaf uncovered in the preheated oven for 50-60 minutes, or until the internal temperature reaches 160°F (71°C) on a meat thermometer. Cooking times may vary depending on the shape of your loaf and your particular oven.

If the top begins to brown too quickly, loosely cover with foil for the remainder of the cooking time to prevent burning while allowing the inside to finish cooking.

Optional: During the last 5 minutes of baking, sprinkle additional mozzarella cheese on top and return to the oven until melted and bubbly for an extra cheesy presentation.

Once done, remove from the oven and let the meatloaf rest for 10-15 minutes before slicing. This resting period is crucial as it allows the juices to redistribute throughout the meat and helps the cheese set slightly so it doesn’t all run out when sliced.

Serving Suggestions

Warm the reserved sauce in a small saucepan or microwave just before serving.

Slice the meatloaf into 1-inch thick pieces using a sharp knife. For the most dramatic presentation, cut slices perpendicular to the cheese center to showcase the melted interior.

Drizzle each slice with the warmed reserved sauce and garnish with freshly chopped parsley.

This cheese-stuffed meatloaf pairs beautifully with:

Creamy mashed potatoes or garlic mashed cauliflower
Roasted vegetables such as carrots, brussels sprouts, or green beans
A simple green salad with vinaigrette
Crusty bread to soak up the delicious sauce
Steamed rice or buttered noodles

For a complete comfort food experience, serve with a side of garlic bread and finish the meal with a warm fruit crisp or cobbler for dessert.

Pro Tips

For the juiciest meatloaf, use a meat mixture that’s at least 15-20% fat
Line your baking sheet with parchment paper for easier cleanup and to prevent sticking
Use a food processor to finely chop the onions if you prefer a smoother texture
Chill the shaped meatloaf for 30 minutes before baking to help it hold its shape
Create a free-form loaf on a baking sheet rather than using a loaf pan for more caramelized edges
Reserve some of the uncooked meat mixture to patch any cracks or holes that might expose the cheese
For perfect slices, allow the meatloaf to rest, then use a serrated knife with a gentle sawing motion
Dampen your hands with cold water when handling the meat mixture to prevent sticking
Add a tablespoon of beef bouillon to the meat mixture for enhanced savory flavor

Variations and Creative Ideas

Flavor Variations

Mediterranean Stuffed Meatloaf: Use feta and mozzarella for the filling, add olives and sun-dried tomatoes to the meat mixture, and use herbs like oregano and basil. Top with a Mediterranean-style tomato sauce.

Mexican-Inspired Meatloaf: Fill with pepper jack or queso quesadilla cheese, add taco seasoning to the meat mixture along with diced peppers, and top with enchilada sauce instead of the traditional glaze.

BBQ Bacon Stuffed Meatloaf: Wrap the cheese center with cooked bacon before encasing in the meat mixture, use BBQ sauce for the glaze, and mix in some smoked cheddar with the mozzarella.

Italian Stuffed Meatloaf: Add Italian sausage to the meat mixture, use provolone and mozzarella for the filling, and top with marinara sauce. Serve with pasta for an Italian-American feast.

Dietary Adaptations

Gluten-Free Version: Replace traditional breadcrumbs with gluten-free breadcrumbs, crushed gluten-free crackers, or cooked quinoa. Ensure all other ingredients, including Worcestershire sauce, are certified gluten-free.

Lower-Carb Option: Substitute almond flour or crushed pork rinds for the breadcrumbs, and use a sugar-free ketchup in the sauce with a keto-friendly sweetener instead of brown sugar.

Dairy-Free Alternative: Use dairy-free cheese alternatives that melt well, such as certain cashew-based or tapioca-based cheese substitutes. The texture won’t be identical, but it can still create a flavorful center.

Leaner Version: Use 90% lean ground beef or substitute ground turkey for some or all of the meat. If using leaner meat, add some additional moisture such as grated zucchini or extra Worcestershire sauce.

Presentation Variations

Mini Cheese-Stuffed Meatloaves: Create individual-sized meatloaves with a cheese center for elegant plating and faster cooking time. Reduce baking time to approximately 30-35 minutes.

Meatloaf Ring: Shape the meat mixture into a ring on a baking sheet, fill the center with the cheese mixture, and bake. When served, each slice has a perfect ratio of meat to cheese.

Muffin Tin Meatloaves: Create individual meatloaf cups in a muffin tin, pressing a cube of cheese into the center of each. These cook quickly and are perfect for portion control and meal prep.

Layered Meatloaf: Instead of a center core of cheese, create horizontal layers of meat mixture alternating with thin layers of cheese for a striking striped effect when sliced.

Storage and Make-Ahead Advice

Refrigerator Storage: Store completely cooled leftover meatloaf in an airtight container in the refrigerator for up to 3-4 days. The flavor often improves after a day as the seasonings meld together.

Freezer Storage:

Baked meatloaf can be frozen for up to 3 months. Wrap individual slices or the whole loaf tightly in plastic wrap, then aluminum foil, and place in a freezer bag.
For best results, freeze without the sauce on top, and add fresh sauce when serving.
Thaw overnight in the refrigerator before reheating.

Make-Ahead Options:

Assemble the entire meatloaf up to 24 hours before baking, cover tightly with plastic wrap, and refrigerate.
When ready to bake, remove from refrigerator 30 minutes before cooking to take the chill off, then bake as directed, possibly adding 5-10 minutes to the baking time.
The sauce can be prepared up to 5 days ahead and stored in an airtight container in the refrigerator.

Reheating Tips:

For best results, reheat meatloaf slices in a 325°F (165°C) oven for about 15 minutes or until heated through.
Microwave individual slices on 70% power, covered with a damp paper towel, for 1-2 minutes.
Add a little beef broth or water to the dish when reheating to maintain moisture.

Not Recommended: Freezing raw, assembled meatloaf, as this can affect the texture and binding properties of the ingredients.

Frequently Asked Questions

Why does my cheese leak out during baking? This typically happens when the seams of the meatloaf aren’t sealed properly. Ensure all edges are tightly pinched together, and consider chilling the assembled loaf for 30 minutes before baking to help it maintain its shape.

Can I use different types of cheese for the filling? Yes! While mozzarella provides the best melt and stretch, you can experiment with cheddar, pepper jack, provolone, or a combination. Avoid very soft cheeses like Brie, which may become too runny.

How do I know when my meatloaf is fully cooked? The most reliable method is using a meat thermometer, which should register 160°F (71°C) when inserted into the meat portion (not the cheese). The meatloaf should also feel firm to the touch, and juices should run clear.

Can I make this in a slow cooker? Yes, though you won’t get the same caramelized exterior. Place the assembled meatloaf in a lined slow cooker, cover, and cook on low for 6-7 hours. For browning, transfer to a baking sheet and broil for 2-3 minutes after slow cooking.

Why is my meatloaf falling apart when sliced? This could be due to insufficient binding ingredients (eggs and breadcrumbs), cutting while too hot, or having too many fillers like vegetables. Always let the meatloaf rest for at least 10 minutes before slicing, and use a sharp knife with a gentle sawing motion.
