Ingredients

Scale

Onion Mixture

  • 2 cups yellow onions, thinly sliced
  • 2 tablespoons olive oil
  • 1 tablespoon butter (can substitute with vegan option)
  • 1 cup beef broth (or vegetable broth for vegetarian option)
  • 1 tablespoon white vinegar (or apple cider vinegar for a milder flavor)
  • 1 tablespoon fresh thyme leaves (can substitute with Italian seasoning or omit)

Dough and Topping

  • 1 package crescent roll dough (all-purpose flour variant)
  • 1 cup Gruyère cheese (can substitute with any melting cheese or vegan cheese)

Instructions

  1. Caramelize Onions: In a large skillet, heat the olive oil and butter over medium heat. Add the thinly sliced yellow onions and cook slowly for about 30 minutes, stirring occasionally, until the onions become soft, golden, and caramelized.
  2. Simmer with Broth and Vinegar: Stir in the beef broth and white vinegar, bringing the mixture to a gentle simmer. Continue cooking for about 5 minutes so that most of the liquid is absorbed and the flavors concentrate. Adjust seasoning to taste.
  3. Prepare Dough Cups: Preheat your oven to 375°F (190°C). Unroll the crescent roll dough and cut it into rectangles that will fit into a greased mini muffin tin. Press each rectangle securely into the wells to form small dough cups.
  4. Fill and Top: Spoon the onion mixture evenly into each dough cup. Then sprinkle the tops generously with grated Gruyère cheese for that classic French onion soup flavor.
  5. Bake: Place the mini muffin tin in the oven and bake for 18-20 minutes or until the dough is golden-brown and the cheese is melted and bubbly.
  6. Cool and Serve: Remove the bites from the oven and let them cool in the tin for about 10 minutes. Gently remove the bites, garnish with additional fresh thyme leaves if desired, and serve warm.

Notes

  • You can substitute beef broth with vegetable broth to make this recipe vegetarian-friendly.
  • Use vegan butter and cheese alternatives to make this a vegan recipe if preferred.
  • Caramelizing onions slowly is key to developing the rich flavor, so do not rush this step.
  • Fresh thyme adds a lovely herbal aroma, but dried Italian seasoning or omission works well too.
  • Make sure to grease the mini muffin tin well to easily remove the bites after baking.
  • These bites are best served warm but can be reheated gently in the oven.
