Turn that leftover meatloaf into something extra special (and tasty!) with this cheesy leftover meatloaf sandwich. With a barbecue mayo, a thick layer of melty cheese, thinly sliced red onion and tangy yellow mustard, this hearty sandwich is made in minutes and is so incredibly delicious!

Remember that ground chicken meatloaf recipe I just shared? Well, today it’s put to good use with these leftover meatloaf sandwiches!

I mean, meatloaf? Good.

Bread? Good.

Cheese? Good.

BBQ mayo? Good.

See where I’m going with this?

Are you a fan of leftovers? We are in our home! I just love recipes where I can get multiple meals from it (especially those that you can turn into something new!).

I really appreciate leftovers during weekdays because the days are busy, and I want something easy, yummy and doesn’t take all day to make, ya know?

Well, these meatloaf sandwiches come together in about 20 minutes (probably less than that, really) and use less than 10 ingredients. How awesome is that?

I like to top this sandwich with processed cheese slices, ya know that almost neon coloured cheese. I don’t know, I just like it here. It’s melty, cheesy and just works. If you’d rather use cheddar or mozzarella cheese, for instance, go for it!

The Sauce

The main sauce or condiment for this leftover meatloaf sandwich is a mixture of mayonnaise and barbecue sauce. Simple? Yes. Delicious? Oh yeah!

To make the barbecue mayo, I simple used a 2:1 ratio of mayonnaise to barbecue sauce. If you want even more barbecue sauce flavour, you could use equal parts mayonnaise to barbecue sauce.

If you’d rather use just mayonnaise or something else instead of the barbecue mayo, though, feel free to do so.

More Sandwich Toppings

If you want to add more oomph to your sandwich, go for it! Lettuce, thinly sliced red or green cabbage, coleslaw, pickles, pickled red onions, sliced pickle or hot peppers (really, any of your favourite sandwich toppings) are all delicious options.

What To Serve With It

As with practically any sandwich, I just love serving this leftover meatloaf sandwich with crunchy potato chips. Other delicious sides are homemade fries, crispy potato wedges, baked potato, tomato basil soup, green salad or simply a pickle.

Course Lunch, Main Course

Servings 2 sandwiches

Ingredients

2 tablespoons mayonnaise
1 tablespoon barbecue sauce
4 slices sandwich bread, use your favourite variety
1 tablespoon olive oil
2 slices leftover meatloaf, about an inch or so thick per slice
2 slices cheese, I used "thick" processed cheese slices (or use your favourite variety)
1 tablespoon water
thinly sliced red onion, to taste
yellow mustard, to taste

Instructions

In a small mixing bowl, whisk together the mayonnaise and barbecue sauce until combined. Set aside.
Heat olive oil in a skillet over medium-low to medium heat. Add the slices of meatloaf and cook for about 3 to 5 minutes on each side until it's slightly golden brown on the outside and heated through.
Fold over each slice of cheese so it's thick. Place a slice of cheese on top of each slice of meatloaf. Add 1 tablespoon of water to the skillet and cover with a lid for about 30 seconds to 1 minute just to warm/melt the cheese. Set the slices of meatloaf aside on a plate while you prepare the toast.
Toast bread to desired doneness and spread the barbecue mayo over one side of all four bread slices.
To assemble each sandwich, top one of the slices of bread with meatloaf, then layer on red onion and drizzle with mustard. Top with the remaining slice of bread (with the barbecue mayo on the inside) to form the sandwich. Serve and enjoy!

Notes

If you really enjoy sauce on your sandwich, feel free to make more of the barbecue mayo. It’s simply a 2:1 ratio of mayonnaise to barbecue sauce. Want more barbecue sauce flavour in your sauce? Use equal parts mayonnaise to barbecue sauce.
