What You Need to Make Caramelized Onions
Ingredients
- Vidalia onions or red onions (or white/yellow onions)
- Canola oil or olive oil
- Baking soda (a pinch)
- Salt
Equipment
- Vegetable slicer or mandoline (optional but helpful for even slices)
- Large skillet
- Sharp knife

How to Make Caramelized Onions – Step by Step
- Peel and slice: Peel the onions, cut in half lengthwise, and slice each half into roughly 1/4-inch slices for even cooking.
- Heat the skillet: Warm 2 tablespoons of oil in a large skillet over medium heat.
- Add onions and baking soda: Add the sliced onions to the hot oil and sprinkle with a very small amount of baking soda (about 1/8 teaspoon for this batch).
- Cook: Stir occasionally and cook for about 10 minutes until the onions turn golden brown and are soft. The baking soda raises the pH and helps the onions brown more quickly.
- Season: Stir in salt just before removing from the pan to taste.
