Gourmet, restaurant quality burgers are super easy to make at home with the right combination of ingredients.

INGREDIENTS NEEDED FOR FRENCH ONION BURGERS:

  • Olive oil and butter
  • Sweet Onions– yellow onions can be substituted.
  • Balsamic vinegar and thyme– give a burst of flavor to the onions. Fresh thyme can be used instead of dry.
  • Ground Chuck– I like to use ground chuck for burgers. The higher fat content creates really juicy, flavorful burgers. You can use lower fat ground beef if you wish.
  • Packet of Dry Onion Soup Mix– provides all the flavor and seasoning for the burgers. So easy!
  • Gruyere Cheese– I love the sharp, buttery flavor of gruyere. Swiss cheese can be used instead or even provolone.
  • Arugula– green leaf lettuce can be substituted.
  • Brioche Buns– I love, love, love brioche buns. They are pillowy soft in texture and have a great buttery flavor. Look for them in the deli section of your grocery store.

These burgers can either be grilled or cooked in a cast iron pan.

The Dijonnaise and onions can be made a day in advance and refrigerated.

Take your time cooking the onions for best flavor. You don’t want the heat too high or you will burn them.

One thought on “French Onion Burgers

  1. I’ve been making French onion burgers as well as onion meatloaf for years. Here I thought it was own personal and secret invention. I made my first meatloaf for the family when I was in 4th grade but with chopped onion. It was back in the days when we made our own beef and chicken broth instead of buying them in cartons. I am 75 now and still cook every night
