Ingredients

caramelized onions;

  • 2 medium-large onions
  • 1 Tbsp olive oil
  • 1 tsp sugar (optional)

french onion burgers;

  • 1 lb ground beef
  • 1 egg
  • cup milk
  • ½ cup breadcrumbs
  • ½ tsp garlic powder
  • ½ Tbsp soy sauce
  • 1.5 oz packet french onion soup mix (I use lipton onion dip and soup mix)
  • 6 potato buns
  • mozzarella cheese

Instructions

caramelized onions;

  • Peel and slice onions into thin slices. You can adjust thickness based on preference, but the thinner, the faster they will cook.
  • Heat a pan over medium-high heat. Add the oil, and allow it to come to temperature.
  • Add onions to pan, and sautee, stirring on occasion until they begin to brown and get color, approx. 8-10 minutes.
  • To fully caramelize the onions naturally, continue cooking until thick and jammy, maybe 10-15 minutes more. To save some time, you can (optional) add 1 tsp of sugar and cook for another 2-4 minutes.
  • Add the remaining French onion soup mix to the caramelized onions and saute another 2 minutes. Once done, remove from the heat and set aside.

french onion burgers;

  • In a large bowl, combine ground beef, 1 egg, ½ cup breadcrumbs, ⅔ milk, ½ tsp garlic powder and ½ Tbsp soy sauce. Add approximately ~¾ of the French onion soup mix, and gently mix together until combined. Do not over-mix. Form 4-6 patties.
  • In a toaster oven or in a broiler, top potato buns with cheese and bake until toasty and melted.
  • In the same pan used for the onions, add another splash of oil and allow to heat. Add the burger patties to the pan and cook to desired done-ness.
  • Build your burger, layering a toasted bun, burger patty, mozzarella cheese and caramelized onions before putting a bun on top. Enjoy!
