Have made these several times and they are always a hit. I do add a teaspoon of sugar (and some salt and pepper) to the onions to help with caramelizing process and cook them much longer than the recipe calls for. The burgers we grill on our Traeger with hickory pellets. We also use gruyere cheese which is more like french onion soup. So yummy and so easy.
Delicious and easy to prepare. I also used dill relish as that is what I had in the refrigerator. A great change from raw onion on a burger.
These were easy and yummy. We are not sweet pickle fans so I made my sauce with dill. We will make these again for sure!
Loved the sauce to go with it. Hubby asks for this almost weekly. Easy to do, and delicious.
Delicious burger! Made with the root veggie fries. My husband & I will be adding this recipe to our regular recipe rotation! Thanks Cooking Light!
