How to Make Sloppy Joe Grilled Cheese
Cook the ground beef and chopped onion in a large skillet over medium heat until the beef is fully browned. Drain any excess grease.
Add mustard, ketchup, and brown sugar to the browned meat. Stir well to combine the homemade sloppy joe sauce and let the mixture simmer for about 5 minutes, allowing the flavors to meld.
Spread butter on one side of each piece of bread. This buttered side will be on the outside of your sandwich, giving it that crispy texture.
Heat a skillet over medium heat. Place a slice of bread, butter side down, in the skillet.
Sprinkle a layer of cheddar cheese on the bread, add a generous scoop of the Sloppy Joe mixture, top with more cheddar cheese, and cover with another slice of bread, butter side up.
Cook the sandwich in the pan until the bottom is golden brown. Then flip carefully, making sure the filling doesn’t spill out. Continue assembling the remaining bread and filling until you have cooked all the sandwiches.

Frequently Asked Questions
What bread works best for Sloppy Joe Grilled Cheese?
A sturdy bread like sourdough or Texas toast bread is ideal as it holds up well to the hearty filling without getting soggy.
Can I use ground turkey or ground chicken instead of beef for this recipe?
Yes, you can easily substitute ground turkey or chicken for beef in this recipe. These alternatives offer a leaner option while still absorbing the flavors from the mustard, ketchup, and brown sugar. Just ensure the poultry is thoroughly cooked to a safe internal temperature before adding the sauces.
Can I use a pre-made Sloppy Joe mix?
Yes, using a canned Sloppy Joe mix can save time and still tastes great. Simply heat it up before adding it to your sandwich.
What types of cheese can I use?
American or Swiss cheese will also work well with the tangy flavor of the Sloppy Joe mix. They melt nicely and complement the flavors.
How do I prevent the sandwich from being too messy?
Keep the Sloppy Joe filling thick and not too saucy, and use a moderate amount to prevent it from spilling out as it cooks.
