Peel and thinly slice the onions.
In a large skillet, melt the butter with olive oil over medium heat. Add the onions, salt, and sugar. Stir well to coat the onions.
Cook the onions over medium-low heat, stirring occasionally, until they are golden brown and caramelized, about 25 minutes. If the skillet becomes too dry, add a splash of beef broth to deglaze and prevent burning.
While the onions cook, prepare the burger patties. In a mixing bowl, combine the ground beef, 1 teaspoon salt, and 1/2 teaspoon black pepper. Form the mixture into four even patties.
In a small bowl, mix together the mayonnaise, Dijon mustard, Worcestershire sauce, and thyme to create the aioli. Set aside.
Heat a skillet or grill pan over medium-high heat. Cook the burger patties for 3–4 minutes on each side, or until they reach your desired doneness.
During the last minute of cooking, place a slice of Gruyère cheese on each patty and cover the skillet with a lid to melt the cheese.
Toast the hamburger buns lightly in a toaster or on a dry skillet.
Spread the aioli evenly on the bottom halves of the buns. Place the burger patties on top, followed by a generous portion of caramelized onions. Top with the other half of the bun.
Serve the French Onion Burgers immediately, paired with your favorite sides like crispy French fries or a fresh salad.
