These burgers have thyme caramelized onions sealed between two pieces of cheese and are smothered in garlic mayo...nothing better than that!
We have burgers every other Friday (for the most part) and I love to try new recipes every now and then. I tend to stick to very traditional burgers because I am pretty particular with burgers. I like them seasoned with only salt and pepper and then the toppings add extra flavor. I'm not a fan of garlic or Worcestershire sauce in burgers even though I am a garlic-aholic. But I do make an exception on occasion. These yummy burgers do have Worcestershire in them, but a majority of the "oomph" in flavor comes from the caramelized onions and very very delicious garlic mayo. It does take a little bit of time to make because of the process of caramelizing the onions, however, it is all worth it in the end!
I slightly adapted the method of building the burger and sealed the caramelized onions in between two slices of cheese to keep them from sliding off the burger while eating. I also added bacon to ours...because bacon :)
