Ingredients for Savory French Onion Soup
Gather these items:
- 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 cup Gruyère cheese (can substitute with any melting cheese or vegan cheese)
How to Make Savory French Onion Soup Step-by-Step
- Step 1: In a large skillet, heat the olive oil and butter over medium heat. Add the thinly sliced yellow onions and cook slowly, stirring occasionally, for about 30 minutes until they are deeply golden and caramelized.
- Step 2: Stir in the beef broth and white vinegar into the caramelized onions. Allow the mixture to simmer gently for about 5 minutes.

- Step 4: Spoon the onion filling evenly into each dough cup. Sprinkle each bite generously with the Gruyère cheese.
- Step 5: Place the muffin tin in the oven and bake the bites for 18-20 minutes, until the dough is golden-brown and the cheese is melted and bubbly.
- Step 6: Allow the bites to cool in the tin for 10 minutes so they firm up slightly, then carefully remove each one. Garnish with fresh thyme leaves and serve warm to enjoy the full flavors of this comforting appetizer.
