• 1/2 tsp smoked paprika (optional, for a gentle smoky depth)

• 1 tsp Dijon mustard
• Pinch of kosher salt
• Pinch of black pepper

Optional Garnishes

• Freshly cracked black pepper
• Flaky sea salt

Step-by-Step Instructions

Step 1: Preheat the oven and prepare your pan

Preheat your oven to 375°F (190°C) with a rack in the center position. Lightly grease a 9×5-inch loaf pan or a small rimmed baking sheet with olive oil or cooking spray. For easier cleanup and to help lift the meatloaf out, line the pan or sheet with a piece of parchment paper or foil, letting it hang over the long sides to create a sling.

If you prefer free-form meatloaf (for more browned edges), use the lined baking sheet and plan to shape the meat mixture into a loaf in the middle of the pan instead of pressing it into a loaf pan.

Step 2: Make the tangy tomato glaze

In a small bowl, whisk together the ketchup, tomato paste, brown sugar, apple cider vinegar, Dijon mustard, salt, and pepper until smooth and glossy. Taste and adjust: add a bit more vinegar if you like extra tangy, or a pinch more sugar for sweeter. Set the glaze aside; it will thicken slightly as it rests, which helps it cling nicely to the meatloaf.

Step 3: Mix the turkey meatloaf base

In a large mixing bowl, add the ground turkey, breadcrumbs, minced onion, minced garlic, eggs, milk, ketchup, Worcestershire sauce, chopped parsley, dried oregano, Italian seasoning, kosher salt, black pepper, and smoked paprika (if using).

Using clean hands or a sturdy spatula, gently mix everything together just until the ingredients are evenly combined. Try not to overwork the mixture, as that can make the meatloaf dense. The mixture should feel moist and slightly sticky but still hold together when you press it into a ball. If it seems too wet, sprinkle in another tablespoon or two of breadcrumbs; if it seems dry or crumbly, splash in an extra tablespoon of milk.

Step 4: Shape the loaf and add the mozzarella center

Place a large piece of parchment or foil on your counter. Transfer about half of the turkey mixture onto it and pat it into a thick rectangle roughly 9×5 inches, about 3/4 to 1 inch thick.

Arrange the mozzarella sticks in a neat line down the center of the rectangle, leaving about a 1-inch border of meat on all sides. If using string cheese, place them end to end so the cheese forms a continuous line through the loaf.

Spoon the remaining turkey mixture over the cheese and gently press and mold it to cover the cheese completely, making sure to seal all seams very well so the cheese does not escape while baking. Use your hands to smooth the surface and shape everything into a tidy loaf. Carefully transfer the loaf to your prepared pan or baking sheet.

Step 5: Bake the meatloaf for the first stage

Place the meatloaf in the preheated oven and bake for 40–45 minutes. At this stage, you are cooking the interior most of the way through before adding the glaze, so it does not burn. The meatloaf should be starting to brown on top and will feel firmer when gently pressed. If you have an instant-read thermometer, the internal temperature at this point will likely be around 140–150°F (60–66°C).

Step 6: Glaze and finish baking

Pull the meatloaf out of the oven and carefully spoon or brush a generous layer of the tomato glaze over the top and down the sides. You will probably use about 2/3 of it; reserve the rest for serving.

Return the glazed meatloaf to the oven and bake for another 10–15 minutes, until the glaze is shiny and set and the internal temperature of the thickest part of the loaf reaches 165°F (74°C). You may see a little cheese starting to bubble at the surface near a seam; that is a good sign the center is melted.

Step 7: Rest, slice, and serve with extra glaze

Remove the meatloaf from the oven and let it rest, loosely tented with foil, for 10 minutes. Resting allows the juices to redistribute and helps the cheese settle slightly so it stays inside the slices instead of running out everywhere at once.

Use the parchment or foil sling to lift the meatloaf onto a cutting board. Slice with a sharp knife into thick pieces, about 1 to 1 1/2 inches wide. Spoon any pan juices and extra glaze over the slices. Sprinkle with additional chopped parsley, a pinch of flaky sea salt, and extra black pepper if you like. Serve warm, making sure each person gets a ribbon of that molten mozzarella center.

Pro Tips

• Do not overmix the meat: Mix just until combined. Overworking the turkey can make the loaf tough and dense instead of tender.
• Seal the cheese well: Take a moment to pinch and smooth every seam so the mozzarella does not leak out. If you see a thin area, patch it with a bit of extra meat mixture.
• Use an instant-read thermometer: Turkey should reach 165°F (74°C). This keeps it food-safe without overcooking and drying it out.
• Rest before slicing: Those 10 minutes of resting time are key for juicy slices and a beautiful melted cheese ribbon.
• Free-form for more browned edges: Baking on a sheet pan instead of in a loaf pan gives more crispy, caramelized surfaces if you like that texture.

Variations

• Spicy mozzarella meatloaf: Add 1/2–1 tsp crushed red pepper flakes to the meat mixture and use pepper jack cheese instead of mozzarella. You can also stir a teaspoon of hot sauce into the glaze for a gentle kick.
• Mediterranean twist: Swap mozzarella for 6 oz of provolone or a provolone–mozzarella blend. Add 1/3 cup chopped sun-dried tomatoes and 1/4 cup grated Parmesan to the meat mixture, and use fresh basil along with parsley.
• Mini cheese-stuffed loaves: Instead of one large loaf, shape 4–6 smaller individual loaves with a bit of mozzarella in each. Reduce the baking time to about 25–30 minutes before glazing, then 5–10 minutes after glazing, checking for 165°F (74°C).

Storage & Make-Ahead

Let leftover meatloaf cool to room temperature, then store in an airtight container in the refrigerator for up to 3–4 days. For easiest reheating, slice the meatloaf before chilling. Reheat slices in a covered baking dish at 325°F (165°C) for 15–20 minutes, or in the microwave in 30-second bursts until hot, adding a spoonful of extra ketchup or reserved glaze to keep things moist.

To freeze, wrap individual slices tightly in plastic wrap, then place in a freezer bag or container for up to 2–3 months. Thaw overnight in the refrigerator before reheating. You can also assemble the raw meatloaf (with cheese center), cover tightly, and refrigerate up to 24 hours before baking; add 5–10 minutes to the first bake time if starting from cold.
