Description
These perfect caramelized onions are rich, sweet, and golden with deep umami flavor. Ideal for topping burgers, adding to pasta, or enhancing side dishes. This slow-cooked onion recipe is naturally sweet, easy to freeze, and an essential kitchen staple.
Ingredients
4 large yellow onions
2 tablespoons olive oil
1 tablespoon unsalted butter
1 teaspoon salt
2 tablespoons water or broth (optional)
Instructions
1. Slice the onions in half, then into thin, even half-moon slices.
2. Heat olive oil and butter in a wide skillet over medium-low heat.
3. Add sliced onions and sprinkle with salt. Stir to coat evenly.
4. Cook uncovered, stirring every 5–10 minutes, for 35 to 45 minutes.
5. If the pan gets too dry, add a splash of water or broth to deglaze.
6. Continue cooking until onions are deeply golden, soft, and sticky-sweet.
7. Taste and adjust salt if needed. Let cool and store as desired.
Notes
Use a wide skillet for more surface area and even browning.
Don’t rush—caramelization takes time and patience.
Deglazing the pan enhances flavor by lifting browned bits.
