Ingredients You’ll Need
This recipe keeps things simple but flavorful. You’ll only need a few pantry staples and a bit of patience to get those onions just right.
For the Filling
- 2 cups yellow onions, thinly sliced – the base of that deep, sweet flavor
- 2 tablespoons olive oil – helps caramelize the onions evenly
- 1 tablespoon butter – adds richness
- 1 cup beef broth (or vegetable broth for vegetarian) – gives depth and savoriness
- 1 tablespoon white vinegar (or apple cider vinegar) – for gentle tang
- 1 tablespoon fresh thyme leaves – adds herby freshness
- Salt and pepper – to taste
For the Dough
- 1 package crescent roll dough – buttery and flaky base
For the Topping
- 1 cup Gruyère cheese, shredded – melts perfectly for that signature topping
Optional Add-Ons or Substitutes
- Swap Gruyère for Swiss, provolone, or vegan cheese
- Add a small dollop of caramelized onion jam for sweetness
- Mix in a teaspoon of Dijon mustard with the filling for a savory kick
- Try Italian seasoning if thyme isn’t available
- Use puff pastry for a slightly fancier version
- Sprinkle chopped parsley or green onions on top after baking for color
Step-by-Step Instructions
These French Onion Soup Bites are built in layers of flavor—first the rich onions, then the flaky dough, and finally that cheesy, golden top.
- Caramelize the onions.
Heat olive oil and butter in a skillet over medium-low heat. Add onions and a pinch of salt. Stir occasionally for 20–25 minutes until they’re golden brown and soft. (This step is where the magic happens—the slower, the sweeter.) - Add flavor depth.
Stir in vinegar, broth, thyme, and a little pepper. Cook another 5–7 minutes until liquid reduces and the onions become jammy. Let cool slightly before using. - Assemble the bites.
Preheat oven to 375°F. Roll out the crescent dough and cut into 12 equal squares. Place each square into a greased mini muffin tin, pressing lightly to form cups. Spoon a bit of onion filling into each, then top with shredded Gruyère. - Bake and serve.
Bake for 12–15 minutes, or until golden brown and bubbly. Let cool 5 minutes before removing from the pan. (They’ll hold their shape beautifully once cooled.)
Quick reminders:
- Stir onions often but don’t rush them—golden, not burnt
- Keep the dough cold before baking for a better rise
- Let the onion mixture cool before adding cheese
- Line your muffin tin with parchment squares for easy release
Expert Tips for Success
Even though these bites are easy, a few small steps help make them perfect every time.
- Always caramelize onions low and slow for sweetness
- Use fresh thyme for the most aromatic flavor
- Don’t overfill the dough cups—they puff up as they bake
- Shred cheese fresh from the block—it melts smoother
- Add a pinch of sugar early in the caramelization to boost flavor
- A splash of vinegar brightens and balances the richness
- Reheat in the oven, not the microwave, to keep them crisp
