How to caramelize onions
Caramelizing onions is all about cooking the onions low and slow. This slow cooking process brings out their sweetness and turns them golden brown. Caramelized onions are delicious added to so many dishes like casseroles, sandwiches, burgers, or pizza.
Carmelizing onions is very easy - it just requires a little patience.
- Preheat a skillet over medium heat. Add the butter and oil.
- Cut the onions into medium or large dice.
- Add the onions to the skillet and once they start to soften, turn the heat down to medium-low. The low temperature helps prevent the onions from drying out. If the onions do start to dry out, turn the heat down or add a splash of water or beef broth.
- Continue cooking, stirring occasionally until the onions turn golden brown, approx. 20-25 minutes.
- A touch of sugar can be added to help speed up the caramelization process, if necessary.
Preparation
While the onions are caramelizing, the other ingredients can be mixed together. Combine the sour cream, mayo, and seasonings. Stir in the caramelized onions after they have cooled slightly.
This dip can be served immediately or refrigerated for several hours or overnight to allow the flavors to blend.
This onion dip is a perfect make-ahead recipe and keeps well in the refrigerator for up to four days.
How to serve
Potato chips are my favorite dipper to serve with this onion dip. For something a little lighter, fresh veggies are a great option too.
