French Onion Soup Bites are a delightful appetizer inspired by the classic French onion soup. These bite-sized treats feature caramelized onions cooked slowly in olive oil and butter, enhanced with sherry vinegar, then layered on flaky crescent roll dough and topped with melted Gruyère cheese. Finished with a sprinkle of fresh thyme, they provide the rich, savory flavors of French onion soup in a convenient finger food perfect for parties or snacks.

Ingredients

Scale

For the Onion Mixture

  • 2 Tbsp. extra-virgin olive oil
  • 1 Tbsp. unsalted butter
  • 2 large yellow onions, thinly sliced
  • Kosher salt, to taste
  • Freshly ground black pepper, to taste
  • 1/2 cup low-sodium beef broth
  • 2 Tbsp. sherry vinegar or red wine vinegar

For the Bites

  • Cooking spray, for greasing pan
  • 2 (8-oz.) cans crescent rolls
  • 4 oz. Gruyère cheese, grated
  • Fresh thyme, for serving

Instructions

  1. Prepare the Onion Mixture: Heat the olive oil and butter in a large skillet over medium heat. Add the thinly sliced onions, seasoning with kosher salt and freshly ground black pepper. Cook slowly for about 25-30 minutes, stirring occasionally, until the onions are deeply caramelized and golden brown.
  2. Deglaze and Flavor: Pour in the low-sodium beef broth and sherry vinegar (or red wine vinegar) to deglaze the skillet, scraping up any browned bits from the bottom. Continue cooking for another 5 minutes until the mixture thickens slightly. Remove from heat and set aside.
  3. Prepare the Crescent Dough: Preheat your oven to 375°F (190°C). Grease a mini muffin pan with cooking spray. Unroll the crescent roll dough and separate it into individual triangles. Press each triangle into the muffin cups, creating a small cup shape with the dough to hold the filling.
  4. Assemble the Bites: Spoon a generous amount of the caramelized onion mixture into each crescent dough cup. Top each one evenly with grated Gruyère cheese.
  5. Bake: Place the filled muffin pan in the oven and bake for 12-15 minutes, or until the crescent dough is golden brown and cooked through, and the cheese has melted and started to bubble.
  6. Garnish and Serve: Remove the bites from the oven and allow them to cool slightly. Garnish each bite with fresh thyme leaves before serving warm for an irresistible appetizer.

Notes

  • Use low-sodium beef broth to control the saltiness of the bites.
  • Gruyère cheese can be substituted with Swiss or fontina if unavailable, but Gruyère provides the best traditional flavor.
  • Make sure to caramelize the onions slowly for maximum flavor development and sweetness.
  • These bites can be prepared ahead of time and reheated gently in the oven before serving.
  • For a vegetarian version, substitute beef broth with vegetable broth.
