Ingredients You’ll Need

The beauty of the ingredients here is how they complement each other to create a rich, satisfying sandwich without any fuss. From creamy mayo to melty cheese and that all-important leftover meatloaf, each element is key to building that perfect layered bite.

• Mayonnaise: It adds creaminess and helps balance the tang of the barbecue sauce perfectly.
• Barbecue sauce: The smoky, sweet notes bring life and moisture to the sandwich.
• Olive oil: For a light sear on the meatloaf slices to add texture and warmth.
• Leftover meatloaf slices: The star ingredient! About an inch thick works best to hold everything together.
• Cheese slices: Thick processed or your favorite variety – I love cheddar or Swiss.
• Water: A little trick to help steam and melt the cheese gently.
• Sandwich bread: Go for your favorite kind; whole-grain works great for a hearty sandwich.
• Thinly sliced red onion: Adds a crisp bite and mild sharpness that cuts through the richness.
• Yellow mustard: The classic tangy kick that pulls all the flavors together.

Variations

I’m all about making recipes your own, and with this Leftover Meatloaf Sandwiches Recipe, you can mix things up based on what you love or what you have on hand. Don’t be shy to experiment with flavors!

• Cheese swap: I once tried smoked gouda instead of cheddar, and it added a lovely depth of smoky flavor that paired beautifully with the barbecue mayo.
• Spicy twist: Adding a slice of jalapeño or a drizzle of hot sauce gave the sandwich a welcome heat wave on a chilly night.
• Healthier option: Using whole-grain bread and low-fat mayo helps lighten it up without sacrificing taste.
• Veggie-packed: I enjoy adding fresh spinach or arugula for some greens and texture in the sandwich.

How to Make Leftover Meatloaf Sandwiches Recipe

Step 1: Whip Up Your Barbecue Mayo Spread

Start by mixing the mayonnaise and barbecue sauce in a small bowl until smoothly combined. This spread is what really jazzes up the sandwich and keeps every bite juicy. I like to prepare this first so it has a moment to meld flavors while I cook the meatloaf slices.

Step 2: Heat and Sear the Meatloaf

Heat olive oil in a skillet over medium-low heat. Place your leftover meatloaf slices in the skillet and let them cook for about 3 to 5 minutes on each side — you’re looking for a lightly golden crust that warmed through without drying out the meatloaf. This step adds a lovely texture and revives the meatloaf’s flavor.

Step 3: Melt the Cheese with a Quick Steam

Now, fold each cheese slice so it’s extra thick and place one over each warm meatloaf slice. Add a tablespoon of water to the pan and cover it quickly to let the cheese melt with a bit of steam. This only takes 30 seconds to a minute — keep an eye on it because melted cheese is a game-changer here.

Step 4: Toast the Bread and Spread the Sauce

Toast your bread just how you like it — I prefer it lightly golden so it holds up without being too crunchy. Then spread that barbecue mayo evenly on one side of all the slices to create a flavorful base for the sandwich.

Step 5: Build Your Sandwich

On one mayonnaise-coated slice, place a melty meatloaf slice with cheese, add thinly sliced red onions for a tangy crunch and drizzle yellow mustard to taste. Top it off with another slice of bread, mayo side down, and you’ve got yourself a hearty, satisfying sandwich ready to enjoy!

How to Serve Leftover Meatloaf Sandwiches Recipe

Garnishes

For me, a few extra red onion slices on the side never hurt—it amps up the flavor and adds a fresh crunch. Sometimes I toss in pickle slices for that tangy kick, or a sprinkle of freshly cracked pepper on top just before serving to wake up the sandwich.

Side Dishes

I love pairing this leftover meatloaf sandwich with crispy sweet potato fries or a fresh green salad to balance the richness. On lazy weekends, a bowl of tomato soup makes an ideal cozy combo — dipping the sandwich in warm soup is pure comfort food bliss.

Creative Ways to Present

For a fun twist when hosting friends, I sometimes cut the sandwich into mini sliders and serve them on a platter with toothpicks—great for grazing and sharing. Layering in some grilled veggies or chutney can really elevate the flavor and presentation too.

Make Ahead and Storage

Storing Leftovers

If you happen to have leftover sandwiches (though I doubt it!), wrap them tightly in foil or plastic wrap and store them in the fridge. I find they keep best when I reheat only the meatloaf part separately to avoid soggy bread.

Freezing

Freezing the assembled sandwich isn’t my go-to because the bread texture can suffer, but freezing leftover meatloaf slices works wonderfully. When you’re ready, thaw and follow the reheating steps below to recreate the sandwich fresh.

Reheating

I usually reheat the meatloaf slices in a skillet over low heat to keep them juicy and then add the cheese melting step as in the original recipe. Toast the bread fresh and assemble just before eating to keep everything tasting homemade and delicious.
