These sliders combine slow-cooked caramelized onions with melted Gruyère cheese on buttery brioche buns, delivering the comforting flavors of French onion soup in a fun, handheld form.

Ingredients

Scale
  • 4 large yellow onions, thinly sliced
  • 3 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 2 cups low-sodium beef broth
  • 1/2 cup dry white wine (optional)
  • 2 teaspoons fresh thyme, finely chopped (or 1 teaspoon dried thyme)
  • Salt and freshly ground black pepper, to taste
  • 12 small brioche slider buns
  • 8 ounces Gruyère cheese, grated
  • 1/2 teaspoon garlic powder (optional)

Instructions

  1. Melt the butter with olive oil in a large skillet over medium-low heat. Add the thinly sliced onions and stir to coat with the butter and oil. Cook gently for 35-40 minutes, stirring every 5 minutes, until onions are soft, deeply golden, and sweet. If onions start to stick or brown too fast, lower the heat and add a splash of water to deglaze the pan.
  2. Stir in thyme, garlic powder, salt, and pepper. Pour in the beef broth and white wine (if using). Bring to a gentle simmer and cook for about 10 minutes to reduce slightly and thicken the broth.
  3. Slice the brioche buns in half horizontally. Optionally, lightly toast them. Arrange the bottom halves on a baking sheet or oven-safe dish.
  4. Spoon a generous amount of the caramelized onion mixture onto each bottom bun half, allowing some broth to soak in but not too much to cause sogginess. Layer shredded Gruyère cheese over the onions.
  5. Place the top halves of the buns on each slider. Bake in a preheated oven at 375°F (190°C) for 10-12 minutes until the cheese is melted and bubbly and buns are slightly toasted. Optionally, broil for 1-2 minutes for a golden top, watching closely to avoid burning.
  6. Remove from oven and let sliders rest for a couple of minutes before serving.

Notes

Caramelize onions low and slow for best flavor. Deglaze pan with broth or wine to prevent burning and add depth. Avoid overloading buns with broth to prevent sogginess. Freshly grated Gruyère melts better than pre-shredded. Sliders can be reheated in oven to maintain texture; avoid microwaving.
