Patty Melt with Bacon and Caramelized Onions
 
 
Ingredients
For each sandwich you'll need:
  • caramelized onions*
  • 2 pieces rye bread
  • 2 slices swiss cheese (or more)
  • 1 hamburger patty, about ¼ lb, cooked
  • 2 pcs. bacon, cooked
  • butter
Instructions
  1. Thinly slice about 1 onion per sandwich and sauté in a couple tablespoons of butter slowly, until golden brown and soft, remove to bowl and set aside.
  2. Cook bacon, set aside
  3. Cook hamburger patty, set aside (shape the patty the same size as your bread)
  4. In same pan you cooked the onions in, add a little more butter (if necessary) and grill one side of two pieces of bread until toasted. Remove and set aside to assemble the sandwich.
  5. Layer one piece of bread, toasted side up, then one piece of cheese (or enough to cover bread), bacon, hamburger patty, onions, more cheese, then top with second piece of toasted bread, toasted side down (facing inside of the sandwich).
  6. Butter the outsides of the sandwich (or add more butter to the pan) and grill sandwich on both sides until golden.
I found about 1 onion is good for one sandwich, so if you're making two sandwiches, use two onions, etc. You can cook them slowly for about 45 minutes to caramelize them or if you're in a hurry, just sauté them until golden brown and soft. If you're cooking several onions, use more butter, enough so they don't stick.

Take your cheese out of the refrigerator before you start. It will melt and cook evenly if it's room temperature. I used a combination of sliced swiss cheese and grated gruyere (feel free to use more than 2 pieces if you want. I like lots of cheese!).
