Ingredients
Scale
Main Ingredients
- 4 large yellow onions, peeled and thinly sliced
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 1 teaspoon salt
- 1/2 teaspoon sugar (optional)
Optional Aromatics
- 2–3 sprigs fresh thyme or 1 bay leaf
Optional Deglazing
- 1/4 cup red or white wine
Instructions
- Prepare the Onions: Peel and slice your yellow onions into uniform thin slices to ensure even cooking and a perfect melt-in-your-mouth texture.
- Heat the Butter and Oil: In a large, heavy-bottomed skillet or pot over medium-low heat, combine the unsalted butter and olive oil to create a balanced fat base that prevents burning and promotes a silky finish.
- Add Onions and Salt: Add the sliced onions to the pan and sprinkle with salt, which helps draw out moisture and accelerates softening without steaming.
- Slow Cook and Stir: Reduce the heat to low and cook the onions slowly, stirring every few minutes to prevent sticking and encourage gradual sugar release. Patience is key—avoid rushing the caramelization.
- Caramelize to Perfection: Continue cooking for 30-45 minutes until the onions turn deep golden-brown. If they start sticking or drying out, add a splash of water or broth to loosen the pan and scrape up flavorful browned bits.
- Optional Step – Add Herbs and Wine: Stir in fresh thyme or bay leaf and pour in a splash of wine to deglaze the pan. Let the liquid simmer until evaporated, enhancing the flavor with brightness and complexity.
- Final Taste and Adjust: Remove herbs, taste, and adjust seasoning by adding a pinch of sugar for extra sweetness or more salt to deepen flavor. Your French Onion Soup-Style Melting Onions are now ready to use.
