Savory French Onion Soup Bites Recipe
Introduction
These Savory French Onion Soup Bites capture all the rich, caramelized flavors of classic French onion soup in a delightful, bite-sized treat. Perfect as an appetizer or party snack, they combine tender onions, melted cheese, and flaky dough for a comforting and elegant bite.

Ingredients
- 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)
- 1 package crescent roll dough (all-purpose flour variant)
- 1 cup Gruyère cheese (can substitute with any melting cheese or vegan cheese)
Instructions
- Step 1: In a large skillet, heat olive oil and butter over medium heat. Add the thinly sliced yellow onions and cook, stirring occasionally, for about 30 minutes until they are deeply caramelized and golden.
- Step 2: Stir in the beef broth and white vinegar. Let the mixture simmer for about 5 minutes until most of the liquid has evaporated. Taste and adjust seasoning as needed.
- Step 3: Preheat your oven to 375°F (190°C). Unroll the crescent roll dough and cut it into rectangles sized to fit your mini muffin tin. Press the dough pieces into the greased mini muffin cups.
- Step 4: Spoon the caramelized onion mixture evenly into each dough cup, then sprinkle the tops with Gruyère cheese.
- Step 5: Bake in the oven for 18-20 minutes, until the dough is golden brown and the cheese is melted and bubbly.
- Step 6: Remove the bites from the oven and let them cool for about 10 minutes. Gently take them out of the muffin tin, garnish with fresh thyme leaves, and serve warm.
Tips & Variations
- For a vegetarian option, substitute beef broth with vegetable broth and use a vegetarian or vegan cheese.
- Try adding a dash of garlic powder or finely chopped garlic to the onions for extra flavor.
- If you prefer a milder vinegar taste, use apple cider vinegar instead of white vinegar.
- These bites pair well with a small side salad or a glass of dry white wine for a complete appetizer experience.
Storage
Store leftover bites in an airtight container in the refrigerator for up to 3 days. To reheat, warm them in a preheated oven at 350°F (175°C) for about 10 minutes or until heated through, which helps keep the dough crisp.

FAQs
Can I prepare the onion mixture ahead of time?
Yes, you can make the caramelized onion mixture a day in advance. Store it covered in the refrigerator and fill the dough cups just before baking.
What if I don’t have a mini muffin tin?
If you don’t have a mini muffin tin, you can form small rounds of dough on a baking sheet, top them with the onion mixture and cheese, and bake similarly. Baking time may vary slightly.

Ingredients
For the 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)
For the 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
- Caramelize the Onions: In a large skillet, heat olive oil and butter over medium heat. Add the thinly sliced yellow onions and cook for about 30 minutes, stirring occasionally, until the onions are deeply caramelized and golden brown.
- Simmer with Broth and Vinegar: Stir in the beef broth and white vinegar into the caramelized onions. Let the mixture simmer gently for about 5 minutes until most of the liquid has been absorbed. Season to taste if necessary.
- Prepare the Dough: Preheat your oven to 375°F (190°C). Unroll the crescent roll dough and cut it into rectangles sized to fit your mini muffin tin. Press each piece firmly into the greased cups of the mini muffin tin to form little dough cups.
- Fill with Onion Mixture: Spoon the warm onion mixture evenly into each dough cup, filling them nearly to the top.
- Add Cheese Topping: Sprinkle Gruyère cheese liberally over each filled cup to cover the onion mixture.
- Bake: Place the mini muffin tin in the preheated oven and bake for 18-20 minutes, or until the dough cups are golden brown and the cheese is melted and bubbly.
- Cool and Garnish: Remove the tin from the oven and let the bites cool for 10 minutes. Gently remove each bite from the tin, garnish with additional fresh thyme leaves if desired, and serve warm.
Notes
- For a vegetarian version, substitute beef broth with vegetable broth and use vegan butter and cheese alternatives.
- Caramelizing onions can take time but is key for developing rich, deep flavor—do not rush this step.
- If you prefer a milder tang, use apple cider vinegar instead of white vinegar.
- Mini muffin tins work best for evenly sized bites that hold their shape.
- These bites are best served warm but can be reheated gently in the oven before serving.
