Step‑by‑Step Instructions for Stuffed Meatloaf with Mozzarella
Step 1: Preheat and Prepare Your Baking Sheet
Begin by preheating your oven to 375°F (190°C). While the oven is heating up, take a baking sheet or loaf pan and lightly coat it with nonstick spray to ensure your Stuffed Meatloaf with Mozzarella easily releases after baking. This step is crucial for a clean and appetizing presentation once out of the oven.
Step 2: Mix the Meat Mixture
In a large mixing bowl, combine the ground beef, breadcrumbs, eggs, milk, diced onion, minced garlic, Worcestershire sauce, tomato paste, salt, black pepper, oregano, and basil. Use your hands to mix gently, ensuring all ingredients are evenly distributed without overmixing. The mixture should feel cohesive yet slightly loose for optimal tenderness in your meatloaf.
Step 3: Shape the First Layer
On a clean surface or directly in your prepared loaf pan, shape half of your meat mixture into a loaf. Create a trench down the center of the loaf without completely cutting through; this is where the mozzarella will nestle. Form the loaf so that it is uniform in thickness and about 1.5 inches high to ensure even cooking.
Step 4: Stuff with Mozzarella
Take your shredded mozzarella and generously fill the trench you created in the meatloaf. Make sure the cheese is evenly distributed for a gooey center in each slice. Once the mozzarella is placed, carefully seal the trench with the remaining meat mixture, molding it over the cheese to fully encase it.
Step 5: Prepare the Glaze
In a small bowl, mix together ketchup, brown sugar, and balsamic vinegar until smooth. This glaze adds a lovely sweetness and depth to your Stuffed Meatloaf with Mozzarella. Brush this mixture liberally over the meatloaf, ensuring it is well-coated for a beautifully caramelized finish during baking.
Step 6: Bake to Perfection
Place your meatloaf in the preheated oven and bake for 50-60 minutes, or until the internal temperature reaches a safe 160°F (71°C). Keep an eye on it, and if the top starts browning too quickly, tent it with foil to prevent burning while the inside finishes cooking.
Step 7: Let It Rest Before Slicing
After removing the stuffed meatloaf from the oven, allow it to rest for 10 minutes. This resting time is essential to maintain its juiciness and ensures cleaner slices. During this time, the cheese will settle slightly, making each piece a mouthwatering delight filled with melty mozzarella.

Make Ahead Options
These Stuffed Meatloaf with Mozzarella are perfect for busy home cooks looking to save time during hectic weeknights! You can prepare the meat mixture and form the loaf up to 24 hours in advance, storing it tightly covered in the refrigerator to maintain freshness. Additionally, you can stuff the meatloaf with mozzarella and add the glaze, fully prepping it for baking ahead of time. When you’re ready to enjoy, simply pop it in the oven straight from the fridge; it may need an extra 5-10 minutes of baking time to account for the chill. To ensure a delicious, juicy result, remember to let it rest for 10 minutes after baking, making your mealtime seamless without sacrificing flavor!

Stuffed Meatloaf with Mozzarella Recipe FAQs
What type of ground beef is best for meatloaf?
When choosing ground beef, look for a blend with a fat content between 80/20 and 85/15. This ratio ensures your Stuffed Meatloaf with Mozzarella remains juicy and flavorful. If you’re looking for a leaner option, ground turkey, especially dark meat, is an excellent substitute that won’t sacrifice moisture.
How should I store leftover stuffed meatloaf?
Leftover slices should be stored in an airtight container in the refrigerator for up to 3 days. If you want to keep it fresh longer, wrap the meatloaf tightly in plastic wrap and aluminum foil and freeze it. When stored properly, it can last for up to 3 months while maintaining its delicious taste!
Can I freeze stuffed meatloaf?
Absolutely! To freeze your Stuffed Meatloaf with Mozzarella, first let it cool completely. Then, wrap it tightly in plastic wrap followed by aluminum foil to prevent freezer burn. Label it with the date, and it can be stored in the freezer for up to 3 months. When ready to enjoy, thaw it in the fridge overnight before reheating.
Why did my meatloaf crumble when I sliced it?
A common reason for crumbling meatloaf is overmixing the meat mixture, which can lead to a dense texture. To avoid this, mix the ingredients gently just until combined. Additionally, ensure that you allow the meatloaf to rest for 10 minutes after baking; this helps retain moisture and keeps it from falling apart during slicing.
Can I use different cheeses in the meatloaf?
Yes, the more the merrier! If mozzarella isn’t your favorite, feel free to swap it out for shredded cheddar, pepper jack, or even a mix of cheeses for a unique taste. Just be sure to adjust the moisture content if needed— drier cheeses like Parmesan might require a little extra moisture in your meat mixture.
Is this recipe safe for pets?
While the Stuffed Meatloaf with Mozzarella is a delicious dish for humans, it’s important to remember that it contains onion and garlic, which can be harmful to pets. Always keep leftover meatloaf out of reach of your furry friends and focus on sharing treats that are specifically safe for their diet!
