What is a bacon butty? It is a bacon sandwich that usually consists of bacon, butter, and a sauce like brown sauce or ketchup between two slices of bread; simple but oh so good.

It is a popular British food for hangovers and can be enjoyed by anybody; even the royals like Prince Harry enjoyed them the morning after Prince William’s wedding. Most bacon sandwiches do not have caramelized onions, but that is what makes this version more satisfying.

Other than the brown sauce, where does the sweetness come from? The white onions! The caramelized part in onions comes from the natural sweetness of the ingredient.

Caramel comes from cooked sugar, so when you slowly cook onions for a long period of time, the sugar in them caramelizes and makes them sweeter.

Cooking bacon in the microwave is quick and easy, but if you want to cook your bacon evenly in the oven, here’s how to do it:

Preheat the oven to 350 degrees Fahrenheit, cover a baking pan with aluminum foil, put the bacon strips on top (do not overlap), and bake for about 20 minutes, or until crispy.

By the time the bacon is done, so will your caramelized onions. The best part is: all you have to do for cleanup is throw away the aluminum foil and paper towels.

What’s your favorite hangover cure?
