French Onion Soup Bites with Caramelized Onions and Gruyère Recipe
Introduction
French Onion Soup Bites capture all the rich, savory flavors of classic French onion soup in a fun, bite-sized treat. These golden crescent dough cups filled with caramelized onions and melted Gruyère cheese make for a perfect appetizer or party snack.

Ingredients
- 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
- Cooking spray, for greasing pan
- 2 (8-oz.) cans crescent rolls
- 4 oz. Gruyère cheese, grated
- Fresh thyme, for serving
Instructions
- Step 1: Generously grease a 24-cup mini muffin pan with cooking spray to ensure easy removal of the bites.
- Step 2: In a large skillet over medium heat, combine the olive oil and butter, heating until the butter melts. Add the thinly sliced onions and season with a generous pinch of kosher salt and freshly ground black pepper. Cook, stirring often, until the onions become tender and richly caramelized, approximately 30 minutes.
- Step 3: Stir in the low-sodium beef broth and sherry or red wine vinegar. Bring the mixture to a simmer and cook, stirring occasionally, until the liquid almost entirely reduces but the onions remain slightly moist, about 5 minutes. Taste and adjust seasoning with salt and pepper if needed. Remove the skillet from heat.
- Step 4: Preheat your oven to 375°F (190°C). Unroll one can of crescent rolls and cut along the perforated line to create two pieces. Then cut each piece lengthwise down the center, producing four large rectangles. Each rectangle should be further cut into three smaller pieces, resulting in 12 pieces per can.
- Step 5: Press each piece into the muffin cups, stretching as necessary to cover the sides and bottom evenly. Repeat this process with the second can.
- Step 6: Spoon approximately 1 tablespoon of the caramelized onion mixture into each dough-lined muffin cup. Evenly sprinkle grated Gruyère cheese over the top of the onions.
- Step 7: Place the muffin pan in the preheated oven and bake until the cheese is melted and the crescent dough turns a golden brown color, about 18 to 20 minutes.
- Step 8: Allow the bites to cool in the pan for 10 minutes before carefully transferring them to a serving platter. Garnish each bite with fresh thyme leaves for added aroma and visual appeal.
Tips & Variations
- Use a mix of yellow and sweet onions for a richer caramelized flavor.
- Substitute Gruyère with Swiss or fontina cheese for a different but delicious twist.
- For extra depth, add a splash of dry white wine along with the broth and vinegar.
- Make sure to cook the onions slowly to develop their natural sweetness and avoid burning.
Storage
Store leftover French Onion Soup Bites in an airtight container in the refrigerator for up to 3 days. Reheat them in a preheated oven at 350°F (175°C) for about 5-7 minutes to keep the crust crisp and the cheese melted.
