Juicy French Onion Burgers with Gruyère
FAQs
What makes these French onion burgers juicy?
Use 80/20 ground beef and mix it only until the seasoning is distributed. Press a shallow dimple into each patty so it cooks evenly, and never press the burgers with a spatula while they cook.
Can I use Swiss instead of Gruyère?
Yes. Swiss is milder and usually less expensive, but it still melts well with the onions. Gruyère gives a nuttier flavor that tastes closer to French onion soup.
Can I make the onions ahead of time?
Yes. Caramelized onions keep well in the fridge for up to 5 days. Rewarm them in a skillet with a splash of beef broth before spooning them onto the burgers.
Can I cook these burgers on a grill?
Yes. Cook the onions in a cast iron skillet on the grill or make them indoors first. Grill the patties over medium-high heat, then add the cheese during the last minute and close the lid to melt it.
How do I keep the onions from burning?
Keep the heat at medium to medium-low once the onions start to soften. Stir every few minutes and add a splash of broth whenever the browned bits on the pan look too dark.
What should I serve with French onion burgers?
Fries are classic, but a crisp salad or pickles help balance the rich onions and cheese. Onion rings, roasted potatoes, or a simple slaw also work well.
