Two comfort food legends just had a baby, and it’s called Meatloaf Grilled Cheese. Juicy homemade meatloaf meets crispy buttered bread and melted pepper jack cheese. Have you ever combined two leftovers and accidentally created something better than the original meal? That’s exactly what happened here.
I first made this on a random Wednesday using leftover meatloaf that was destined for the trash. IMO, it turned out so good that I now make extra meatloaf on purpose just for these sandwiches.

What Makes Meatloaf Grilled Cheese So Good?
This isn’t just a sandwich with meatloaf slapped inside it. The BBQ-spiked meatloaf gets crisped between buttery, golden bread with two layers of gooey pepper jack cheese. It tastes like a diner special that somehow got even better.
Why does this combo work so well? Because meatloaf already has bold, savory flavor, and grilling it inside bread with melted cheese amplifies every bit of that richness.

Some recipes sound better than they taste. This one delivers every single time, and here’s exactly why it deserves a spot in your dinner rotation:

Ingredients You’ll Need
Nothing fancy here, just honest ingredients that create massive flavor together. Here’s exactly what you need for both the meatloaf and the sandwich:
- 1 pound ground beef
- 1 egg
- 1 tablespoon mustard
- 1/4 cup BBQ sauce
- 1 teaspoon garlic powder
- 1/2 teaspoon black pepper
- 1/8 cup onion, minced
- 1/2 cup bread crumbs
- 4 slices pepper jack cheese
- 4 slices bread
- Butter for grilling
FYI, you can swap in leftover meatloaf here and skip the baking step entirely if you’re short on time.
How to Make Meatloaf Grilled Cheese (Step-by-Step)
This process breaks into two simple parts: baking the meatloaf and grilling the sandwich. Neither step requires any special skill, so let’s walk through it together.
Step 1: Preheat and Prep
Start by preheating your oven to 375°F so it’s fully ready when your meatloaf mixture goes in. While it heats, grab a 4×8 baking pan and set it aside for later.
Step 2: Mix the Meatloaf Base
In a medium bowl, combine the ground beef, egg, mustard, BBQ sauce, garlic powder, black pepper, and minced onion. Mix everything together with your hands or a sturdy spoon until fully combined.
Add the bread crumbs next and mix again until the whole mixture holds together firmly. You want it moist but not falling apart when you shape it.
Step 3: Shape and Bake the Loaf
Shape the mixture into a neat oval loaf and place it directly into your prepared baking pan. Spread a little extra BBQ sauce across the top for a sticky, flavorful crust.
Cover the pan tightly with foil and slide it into the oven. Bake for about 45 minutes, or until the meatloaf reaches full doneness with no pink remaining inside.
Step 4: Let It Rest
Pull the meatloaf out of the oven once it’s fully cooked and set it on a plate. Let it rest for about 20 minutes before cutting into it.
Skipping this rest is a rookie mistake. The loaf needs that time to firm up, or your slices will fall apart the second you touch them.
Step 5: Slice the Meatloaf
Once rested, cut the meatloaf into slices roughly 3/4 inch thick. This thickness gives you enough meaty bite without overwhelming the sandwich.
Step 6: Prep the Bread
Butter one side of each slice of bread generously. This buttered side is what creates that irresistible golden, crispy crust once it hits the skillet.
Step 7: Build the Sandwich
Heat a large skillet over medium heat and place one slice of bread buttered side down. Lay one slice of pepper jack cheese directly on top of the bread.
Stack enough meatloaf slices on the cheese to cover the bread evenly. Add a second slice of cheese over the meatloaf, then top it off with the remaining slice of bread, buttered side facing up.
Step 8: Grill Until Golden
Cook the sandwich until the bottom slice of bread turns golden brown and crispy. Carefully flip it over using a spatula, then cook the second side until it matches that same golden crunch and the cheese melts completely.
Step 9: Slice and Serve
Remove the sandwich from the skillet and let it sit for a minute before slicing. Cut it diagonally for that classic grilled cheese presentation, then serve it while it’s still hot and gooey.
Serving Suggestions That Actually Work
A sandwich this rich deserves the right sidekicks on the plate. Try pairing it with any of these classic options:
- A bowl of warm tomato soup
- Crispy fries or potato chips
- A fresh side salad
- Pickles or coleslaw for tangy contrast
- Diagonal cuts for easier sharing
Skipping a side isn’t a crime, but tomato soup turns this into an instant nostalgia trip.
Storage and Reheating Tips
Leftover meatloaf makes this sandwich even easier the second time around. Here’s how to store everything properly:
- Refrigerate leftover meatloaf in an airtight container for up to 3 days
- Reheat meatloaf slices in a skillet or microwave before assembling
- Freeze cooked meatloaf slices individually for up to 2 months
- Wrap slices separately for quick, easy reheating later
- Avoid freezing fully assembled sandwiches, since the bread turns soggy
Fun Variations to Try Next Time
Once you’ve nailed the classic version, why not switch things up? This sandwich handles creative twists really well.
- Classic cheddar version: swap pepper jack for sharp cheddar
- Spicy jalapeño version: add sliced jalapeños for extra heat
- Bacon version: layer in crispy bacon strips for richness
- Italian version: add marinara sauce and mozzarella instead
- Breakfast version: tuck a fried egg inside for brunch vibes
Have you ever added a fried egg to a sandwich and instantly regretted not doing it sooner? Same here.
