Total Time: 35 mins

Servings: 6

Ingredients

• 3 tablespoons canola oil
• 4 yellow onions , thinly sliced
• 2 teaspoons kosher salt
• 1/2 cup beef broth
• 2 tablespoons Worcestershire sauce
• 2 tablespoons sherry vinegar
• 1 tablespoon fresh thyme leaves, finely chopped, plus more for garnish
• 2 teaspoons freshly ground black pepper
• 1 cup mayonnaise
• 3 tablespoons Country Dijon mustard
• 6 Hawaiian or brioche hot dog buns
• 6 cooked beef hotdogs
• 2 1/2 cups freshly shredded Gruyere cheese

Steps

1. Arrange a rack to the upper third position of oven. Preheat oven to broil.
2. Heat oil in a large skillet over high heat until shimmering, about 30 seconds. Add onions, toss until well coated in oil, and cook undisturbed until browned on one side and slightly softened, 5 to 7 minutes. Stir onions and continue to cook undisturbed until browned on other side, 5 to 7 minutes.
3. Add salt and broth and cook, making sure to scrape up any brown bits stuck to the bottom of the pan, until most of the liquid is absorbed, about 2 minutes. Stir in Worcestershire sauce, vinegar, thyme, and black pepper, and cook until fragrant and onions are brown all over, about 1 minute. Remove from heat.
4. Whisk together mayo and Dijon mustard until smooth; transfer Dijonnaise sauce to a squeeze bottle if desired.
5. Place hotdog buns on a large rimmed baking sheet. Add a hotdog to each bun, drizzle with prepared Dijonnaise sauce, and top with about 1/3 cup caramelized onions. Sprinkle each hotdog with a generous amount of cheese.
6. Broil in the preheated oven until cheese is melted and brown, about 2 minutes. Garnish with thyme leaves.
