How To Make And Assemble A Meatloaf Sandwich

This is a quick caramelized onion recipe, not one that’s going take 30 minutes or longer for that extra deep caramelization flavor.

Just about 7-8 minutes in a skillet is all you need!

Add sliced yellow onions to a skillet with butter, salt and fresh thyme sprigs. Cook while stirring occasionally for 7-8 minutes until the onion soften and turn brown in color. Remove the thyme and set aside.

Wipe out the same skillet, add more butter and then place your meatloaf slices into the skillet. Brown for 2 minutes on each side until the meatloaf gets a nice crispy crust on the outside.

Add a good amount of the onions to each slice of meatloaf, top with a slice of provolone cheese and then cover the skillet with a lid to melt the cheese.

Add the two slices of meatloaf to your favorite bun, we’re using a Portuguese roll here, and add any additional condiments that you like.

What Condiments Go Well With Meatloaf?

Ketchup is a favorite in our house, especially with the kids. My personal favorite is mayonnaise, but there are so many more options, too!

What Other Types Of Cheese Are Good With Meatloaf?

Really any type of melting cheese that you like. Mozzarella is another good option, Monterey Jack, cheddar, gruyere and even good ol’ classic American cheese!

And of course, you can skip the cheese altogether if you like and just pour on brown gravy or your favorite condiments.
