Ingredients for Perfect Caramelized Onions
- 2 yellow onions
- 2 tablespoons butter (30 g, roughly measured)
- 2 tablespoons olive oil (30 ml, roughly measured)
- Water, broth, beer, or wine for deglazing
How to Make Perfect Caramelized Onions
Prepare the onions
Cut the roots off each onion. Slice the onions in half, then slice them into thin strips, approximately 1/8 inch (3 mm) thick. Ensure uniform slices to avoid uneven cooking.
Heat the pan with oil and butter
Add enough olive oil and butter to coat the bottom of a large pan. Butter adds a rich flavor, but it can burn, so keep an eye on the heat.
Add the onions
Place the sliced onions into the heated pan, ensuring they’re evenly coated with the oil and butter mixture. Cook them over low to medium-low heat—high heat will burn them before they caramelize.
Begin stirring
Stir the onions every few minutes to prevent sticking or burning. This initial stage will take around 10 minutes as they begin to soften.
Deglaze the pan
When the onions start to stick and leave browned bits at the bottom, add a splash of water, broth, beer, or wine to deglaze. This helps lift the flavorful residue and prevents burning.
Cook slowly and stir often
Continue cooking the onions for another 10 minutes, stirring regularly to allow them to cook evenly.
Repeat deglazing
As the onions darken, repeat the deglazing process to scrape up the browned bits and ensure consistent caramelization.
Cook until perfectly caramelized
Keep stirring and deglazing as needed. This slow process can take up to 40 minutes, but the reward is worth the effort. The onions should be a deep golden-brown color without being burnt.
Taste and adjust
Once the onions are perfectly caramelized, taste them and adjust the seasoning if desired.
Serve and enjoy
Your caramelized onions are now ready to enhance your favorite dishes. Their deep, rich flavor is sure to impress!
