Recipe ingredients
This recipe calls for a hand full of ingredients, most of which you probably already have on hand. Here are some notes on the specific ingredients:
- Sliced onion: I like to cut the onion lengthwise into long strips. However, you can cut them smaller if you wanted smaller pieces of onion in the final dip.
- Thyme: fresh thyme is great in this recipe, however a teaspoon of dried thyme can be substituted in its place.
- Yogurt: the yogurt gives the dip a bit of tangy taste. You can use plain yogurt or greek yogurt. If you don’t have yogurt, substitute sour cream in its place.
Caramelized Onion Dip Recipe
Caramelized Onion Dip is a delicious appetizer that you can make up to two days in advance. Plus, it seems the longer it sits the better it gets. Follow along to see how easy it is to make this fan-favorite appetizer dip.
The first step to making this dip is the caramelize the onions. Firstly, you need to thinly slice the onions. To start, cut the onions in half lengthwise and peel off the skin. Then, use a very sharp knife to cut long thin strips of onion.
Place the sliced onions in a large dutch oven or skillet (step 1). I find a dutch oven does a great job for caramelizing onions, like this pretty one from Lodge.
To the onions, add in minced thyme and kosher salt. If you don’t happen to have fresh thyme, you an always a teaspoon of dried thyme instead.
Then, cook the onions on low heat, stirring occasional, until they soften and start to brown. This usually takes about 30-40 minutes (step 2). Once the onions have caramelized, take them off the heat and let them cool slightly.
Next, in a large bowl, whisk together the mayo, sour cream, yogurt, apple cider vinegar, garlic powder, and seasonings (step 3).
Fold in the caramelized onions and stir until fully incorporated (step 4).
For best results, I recommend refrigerating the dip for at least an hour or overnight. Personally, I find the longer it sits, the better it gets.
