Recipe Overview

Prep time: 20 minutes.

Total time: About 1 hour 20 minutes including resting.
Servings: 6 (slices).
Difficulty: Medium — shaping and stuffing require gentle hands but no advanced skills.
Method: Mix, shape around a mozzarella log, bake uncovered until cooked through, then rest before slicing.

My Experience Making This Recipe

I tested this meatloaf using 80/20 ground beef and a low‑moisture mozzarella log for a reliable melt and less water release. The main challenge was keeping the cheese fully enclosed; chilling the formed loaf for 15–20 minutes helped it hold its shape during baking.

How to Make Stuffed Meatloaf with Mozzarella

Start by combining 1.5 lb (700 g) ground beef, 1 large egg, 1/2 cup plain breadcrumbs, 1/4 cup whole milk, 1 small minced onion, 2 cloves minced garlic, 1 tsp kosher salt, 1/2 tsp black pepper, and 1 tbsp Worcestershire sauce in a large bowl. Flatten the mixture on plastic wrap into a rectangle, lay a 4–6 oz (115–170 g) low‑moisture mozzarella log lengthwise, and roll the meat around it, sealing seams and tucking ends. Chill for 15–20 minutes, brush with a ketchup-or-bbq glaze, then bake at 375°F (190°C) for 50–60 minutes until an instant‑read thermometer in the meat (not the cheese) reads 160°F (71°C). Rest 10 minutes before slicing so the juices redistribute and the cheese sets a bit.

Expert Tips for Success

Use 80/20 ground beef or a 50/50 mix of beef and pork for moisture and flavor; leaner meat dries out faster.
Keep the mozzarella cold and use low‑moisture cheese to reduce oozing; a chilled cheese log is easier to encase.
Chill the shaped loaf for 15–20 minutes before baking to firm it up and prevent collapse or splitting.
Use an instant‑read thermometer to check doneness at the thickest part of the meat (target 160°F / 71°C). For a stronger sear on the exterior, sear the loaf in a hot skillet 1–2 minutes per side before baking.

How to Serve Stuffed Meatloaf with Mozzarella

Serve slices with a simple green salad and roasted potatoes for a classic plate. Pair it with a bright side like chayote with dried green chile to add texture and a hint of heat. For a cozy dinner, serve alongside garlic mashed potatoes and steamed green beans, and garnish slices with chopped parsley for color.

Storage and Reheating Guide

Refrigerate leftovers in an airtight container for 3–4 days. To freeze, wrap the cooled whole loaf tightly in plastic wrap and foil, or slice and freeze individual portions in freezer bags for up to 3 months. Reheat from chilled in a 325°F (160°C) oven covered with foil for 15–20 minutes until warmed through, or microwave single slices on medium power, covered, for 1–2 minutes — finishing in a hot skillet for 30 seconds helps refresh texture.

Recipe Variations

Gluten‑free: Replace breadcrumbs with 1/2 cup almond flour or gluten‑free breadcrumbs and use gluten‑free Worcestershire.
Dairy‑free: Use a dairy‑free mozzarella alternative or replace the cheese center with roasted red peppers and sautéed mushrooms.
Low‑carb/keto: Omit breadcrumbs and use 1/4 cup almond flour with an extra egg to bind.
Flavor twist: Add 1/4 cup finely chopped sun‑dried tomatoes and 1 tsp Italian seasoning to the meat for a Mediterranean profile.

Nutritional Highlights

This dish is protein-rich and satisfying, making it useful for balanced meals focused on satiety. Watch portion sizes — a typical serving (about 1/6 of the loaf) provides substantial calories and saturated fat depending on meat and cheese choices. Allergens to note: milk (mozzarella), eggs, and wheat (breadcrumbs) — suitable substitutions are listed in variations.

Troubleshooting Common Issues

If the cheese oozes out while baking, it likely got too warm before encasing or the seam wasn’t sealed; next time chill the loaf and press seams firmly, or wrap ends with a little extra meat. If the meatloaf collapses or flattens, don’t overwork the meat during mixing and chill before baking to help it hold shape. If the meatloaf is dry, reduce baking time slightly, choose fattier ground meat, or add a splash of milk or grated onion to the mix.

Frequently Asked Questions

Q: Can I use ground turkey or chicken instead of beef?
A: Yes — you can substitute ground turkey or chicken, but these lean meats dry out faster. Use an extra egg, 2–3 tablespoons of olive oil, or a 25% ratio of pork to keep moisture, and reduce oven time slightly while watching internal temp (target 165°F / 74°C for poultry).

Q: How do I prevent the cheese from melting through the meatloaf?
A: Use low‑moisture mozzarella and keep it well chilled while wrapping. Make a tight seal by pressing seams firmly and tucking ends. Chilling the formed loaf for 15–20 minutes before baking helps the meat hold together while the cheese heats.

Q: Can I assemble the meatloaf ahead of time?
A: Yes — you can assemble the loaf and refrigerate it, covered, for up to 24 hours before baking. Bring it out of the fridge 15 minutes before baking so the oven temperature affects it evenly, and add a few extra minutes to baking time if still quite cold.

Q: What’s the best way to tell when the meatloaf is done without slicing it open?
A: Use an instant‑read thermometer inserted into the thickest part of the meat (avoid the cheese center). For beef/pork blends target 160°F (71°C). After removing from the oven, rest the loaf 10 minutes; the residual heat will finish cooking and make slicing cleaner.
