Ingredients

Caramelized Onions
  • 3 medium sweet onions
  • 2 tablespoons butter
  • salt and pepper
Sauce
  • 1/4 cup mayonnaise
  • 2 tablespoons ketchup
  • 1 tablespoon relish
  • 1 teaspoons sugar
  • 1 teaspoons vinegar
  • 1 teaspoon garlic powder
  • 1/2 teaspoon paprika
Burgers
  • 1 pound ground beef
  • salt and pepper
  • 8 lices bread rye, sourdough, or Texas toast are all popular choices
  • 8 lices cheese
  • 4 tablespoons softened butter

Instructions

    Cup of Yum
  1. Slice the root end and the stem end off of each onion. Remove the outer peels, then cut the onions in half from top to bottom. Working with one half at a time, cut slices from top to bottom, keeping them all about the same same size. (This is the opposite of cutting the onion into half moons.)
  2. Melt the butter over medium-low heat in a heavy skillet (I like a cast iron skillet) and then add the onions. Cook, stirring often, until the onions are golden and caramelized. This will take about 35-40 minutes if you still want a little bit of a bite to your onions. You can take them even farther and completely soften them, but I like a little bit of texture still for these sandwiches.
  3. Add some salt and pepper, to taste, about 3/4 of the way through. When the onions are done, you’ll want to taste and season again, if needed. Remove the onions from the skillet and wipe it out.
  4. In a small bowl, combine the mayonnaise, ketchup, relish, sugar, vinegar, garlic powder, and paprika.
  5. Take the ground beef and divide it into 4 even portions. Shape each into a thin patty and season both sides with salt and pepper.
  6. Heat the skillet over medium-high heat and add the patties. (You may need to do this in batches, depending on the size of your pan.) Cook the patties until they are browned, then flip and cook the second side. They cook quickly - it should only take about 3 minutes per side.
  7. Assemble the sandwiches: Lay the bread out on a counter or work surface. Spread some of the sauce on each of the slices of bread, then top each with a slice of cheese. Add the 4 patties to the tops of 4 of the pieces of bread, then layer the onions on top of the patties. Place the other pieces of bread on top, cheese side down.
  8. Spread 1/2 tablespoon of softened butter on the outsides of each slice of bread.
  9. Heat a skillet or griddle over medium heat. Add the sandwiches, and cook until toasted on both sides and the cheese is melted.
  10. Cut in half to serve.

Notes

  • If your pan has a lid, I like to cover the sandwiches for part of the grilling to make sure the cheese melts. If you don’t have a lid, you can also use loosely tented foil.
