Ingredients

For the Meatloaf

• 2 pounds ground beef
• 1 cup breadcrumbs
• 1 large egg
• ½ cup milk
• 1 small yellow onion, finely diced
• 2 tablespoons Worcestershire sauce
• 1 teaspoon garlic powder
• 1 teaspoon Italian seasoning
• ½ teaspoon salt
• ½ teaspoon black pepper

For the Filling

• 1½ cups shredded provolone or mozzarella cheese
• 1 green bell pepper, thinly sliced
• 1 small yellow onion, thinly sliced
• 1 tablespoon olive oil

For the Topping

• ½ cup ketchup
• 1 tablespoon Worcestershire sauce

How to Make Stuffed Philly Cheesesteak Meatloaf

1. Prepare the Oven

Preheat your oven to 375°F (190°C).

Line a baking sheet or loaf pan with parchment paper or lightly grease it.

2. Cook the Peppers and Onions

Heat the olive oil in a skillet over medium heat.

Add the sliced bell pepper and onion. Cook for about 5–7 minutes, stirring occasionally, until softened.

Remove from the heat and allow the vegetables to cool slightly.

3. Make the Meatloaf Mixture

In a large bowl, combine the ground beef, breadcrumbs, egg, milk, diced onion, Worcestershire sauce, garlic powder, Italian seasoning, salt, and black pepper.

Mix gently with your hands or a wooden spoon until everything is evenly combined. Avoid overmixing, which can make the meatloaf dense.

4. Shape the Meatloaf

Place the meat mixture on a large sheet of parchment paper and gently flatten it into a rectangle about ¾-inch thick.

Leave a small border around the edges.

5. Add the Cheesesteak Filling

Sprinkle the shredded cheese evenly over the center of the meat mixture.

Add the sautéed peppers and onions over the cheese.

Carefully roll the meatloaf around the filling, sealing the edges and ends completely so the cheese stays inside during baking.

Place the meatloaf seam-side down on the prepared baking sheet or in a loaf pan.

6. Add the Topping

Mix the ketchup and Worcestershire sauce together.

Spread the mixture evenly over the top of the meatloaf.

7. Bake

Bake uncovered for approximately 50–65 minutes, depending on the size and shape of the loaf.

The center should reach an internal temperature of 160°F (71°C) for ground beef.

If the top begins browning too quickly, loosely cover it with foil during the final portion of baking.

8. Rest and Slice

Remove the meatloaf from the oven and let it rest for about 10–15 minutes before slicing.

This allows the juices to redistribute and gives the melted cheese time to settle inside.

Slice into thick pieces and serve warm.

Tips for the Best Philly Cheesesteak Meatloaf

Don’t overmix the ground beef mixture. Gentle mixing helps create a tender meatloaf.

Allow the sautéed peppers and onions to cool slightly before adding them to the cheese filling.

Seal the meatloaf carefully around the edges. Any openings can allow melted cheese to escape during baking.

Let the meatloaf rest before slicing. Cutting it immediately can cause the cheese and juices to spill out.

Use an instant-read thermometer to confirm the center reaches 160°F (71°C).

Easy Variations

• Classic cheesesteak: Use provolone cheese for a traditional cheesesteak-inspired flavor.
• Extra cheesy: Add another ½ cup of cheese to the center.
• Mushroom: Add sautéed mushrooms with the peppers and onions.
• Spicy: Add sliced jalapeños or crushed red pepper.
• Cheddar version: Replace some of the provolone with sharp cheddar.
• Turkey: Substitute ground turkey, cooking until it reaches 165°F (74°C).

What to Serve With Philly Cheesesteak Meatloaf

This hearty meatloaf pairs beautifully with mashed potatoes, roasted potatoes, green beans, corn, roasted vegetables, or a simple garden salad.

For an extra cheesesteak-inspired meal, serve it with crispy fries and additional sautéed peppers and onions.

How to Store Leftovers

Store leftover meatloaf in an airtight container in the refrigerator for up to 3–4 days.

Reheat individual slices in the microwave or place them in a covered baking dish and warm gently in the oven.

You can also freeze cooked meatloaf slices for up to 3 months. Wrap individual portions well before placing them in a freezer-safe container.

Frequently Asked Questions

Can I use ground turkey instead of beef?

Yes. Ground turkey can be substituted, but cook it to an internal temperature of 165°F (74°C).

What cheese is best for stuffed meatloaf?

Provolone is an excellent choice because it melts smoothly and gives the meatloaf a classic cheesesteak flavor. Mozzarella, cheddar, or a combination can also be used.

Can I prepare this meatloaf ahead of time?

Yes. Assemble the meatloaf, cover it tightly, and refrigerate it for up to 24 hours before baking. Let it sit out briefly while the oven preheats, then bake until the center reaches 160°F (71°C).

Why did the cheese leak out?

Cheese can escape if the meatloaf isn’t sealed well around the edges. Leave a border around the filling and pinch the meat mixture firmly together before baking.
