Instructions
 

Make the Caramelized Onions

  • Peel and thinly slice the Vidalia onion, discarding the tip and root end.
  • In a large sautè pan warm the olive oil on med-low heat.
  • Add the sliced onions to the pan and coat with the olive oil.
  • Cook stirring occasionally, once the onion start to soften add a pinch of salt and 1/2 tsp of sugar (optional). Watch that they don't burn, if the onions are getting to dark lower the heat.
  • Cook until the onions appear soft, jammy and have a nice light to medium brown color 30-60 min.
  • Store in a glass jar in the refrigerator. Remove from the refrigerator 1/2 hour before serving so they come to room temp.

Make The Zesty Burger Sauce

  • Combine the mayo, ketchup, garlic powder, Worcestershire sauce, and 1/2 tsp of black pepper into a bowl. Mix well, taste if it's not spicy enough add the remaining black pepper.
  • Refrigerate covered and let flavors blend together for at least 2 hours.

Cook & Assemble Burgers

  • Cook burgers until desired level of doneness.
  • Top with cheese and melt if desired.
  • Add remaining toppings as desired finishing off with caramelized onions and burger sauce.

Notes

Store caramelized onions covered in the refrigerator up to 5 days or you can freeze them.
Store the zesty burger sauce in a sealed container in the refrigerator for up to 5 days.
The burger sauce is great for dipping french fries.
You can use the smaller onions but keep in mind you will need to use more than one. The Vidalia onion is on the larger side so you don't have to use as many. 
If you want to double the caramelized onion recipe I suggest using two large pans so the onions have room to breathe and not steam themselves. It will also make the process go a bit quicker.
