Burger with Fried Eggs & Caramelized Onions

Our household is always up for a good burger night. There are so many ways we enjoy them, you can find a lot of those recipes here. Today I'm sharing how I make a fairly decadent burger that's topped with a fried egg and caramelized onions. It takes a little skill to get it all just right and the efforts are so rewarding.

The part of this burger that takes the longest is making the caramelized onions. This is always a bit of an exercise in patience because you want the onions to be sweet and cooked through, without getting burned. If they're undercooked they don't taste good either, the onion is too pungent and raw. The whole process varies slightly depending on the amount of heat you use and the freshness of the onions, so take your time. The caramelized onions can be made in advanced and reheated when you're ready to use them!

The rest of the recipe is fairly straightforward. Cook the burgers and the prepare the eggs fresh at the end so they are still hot and the yolk is runny. Then, assemble the burger and serve it right away! I always have homemade french fries on the side along with a good salad.

This is a great recipe for summer grilling. Whip these up tonight and enjoy a fun meal with your family!
