Step-by-Step Instructions
- Preheat Oven
- Set your oven to 375°F to ensure it reaches the proper temperature while you prepare the meatloaf. Position the rack in the middle for even cooking throughout.
- Mix Meat Ingredients
- Combine ground beef and sausage in a large bowl then add onion, garlic, breadcrumbs, eggs, Parmesan, herbs, and milk. Mix with your hands until just combined but avoid overworking which can make the meatloaf tough.
- Form Base and Add Filling
- On a parchment-lined baking sheet, shape the meat mixture into a rectangle about 9×12 inches and approximately half-inch thick. Press the center to create a shallow well, leaving a substantial border around all edges to contain the filling.
- Add Cheese and Filling
- Sprinkle mozzarella evenly down the center of your meat rectangle, leaving that border intact. Layer chopped spinach over the cheese if using, then drizzle a thin line of marinara down the center.
- Seal the Meatloaf
- Carefully fold the long sides of the meat rectangle over the filling, overlapping slightly and pressing to seal. Then fold the shorter ends over and press all seams firmly to prevent cheese from leaking during baking.
- Top and Bake
- Spread marinara sauce over the entire top surface of the meatloaf then sprinkle with remaining Parmesan cheese. Bake for 45-55 minutes until the internal temperature reaches 160°F.
- Rest Before Serving
- Allow the meatloaf to rest for at least 10 minutes after removing from the oven. This crucial step lets the juices redistribute and makes slicing cleaner and easier.

This meatloaf reminds me of Sunday dinners at my grandmother's home in New Jersey. She always stuffed her meatballs with small pieces of mozzarella, and this recipe carries on that tradition but in a more substantial form that feeds the whole family with less work.
Make-Ahead Options
You can prepare this meatloaf up to 24 hours before cooking. Simply assemble the entire loaf, cover tightly with plastic wrap, and refrigerate. When ready to bake, remove from refrigerator about 30 minutes before cooking to take the chill off, then add about 10 minutes to the baking time since you're starting with cold meat.
Flavor Variations
The basic stuffed meatloaf concept works beautifully with different flavor profiles. Try substituting provolone for a sharper cheese taste, add roasted red peppers to the filling for sweetness, or mix in chopped sun-dried tomatoes to the meat mixture for concentrated flavor. For a Greek-inspired version, use feta and spinach as filling and add oregano to the meat mixture.
Serving Suggestions
This meatloaf pairs perfectly with garlic mashed potatoes, which help soak up the delicious sauce. A simple Caesar salad provides a crisp contrast to the rich meat. For a complete Italian-inspired meal, serve with a side of pasta tossed with olive oil and herbs. I also recommend having extra warm marinara sauce available at the table for those who enjoy more sauce with each bite.
Troubleshooting Tips
If your meatloaf splits during baking exposing the filling, don't worry about the appearance. The flavor remains delicious, and you can spoon any escaped cheese over each slice when serving.
