This homemade caramelized onion dip far surpasses any store-bought version. With the perfect blend of sweet and savory, this is the best onion dip and is a must-make for any party or game day spread.
Heat a skillet over medium-low heat and add the butter to melt.
Add the onions to the skillet. Cook the onions until they start to soften and turn translucent. Continue cooking, stirring occasionally, until the onions have turned golden brown. This process will take 30-45 minutes. Let the onions cool.
Meanwhile, in a mixing bowl, combine the sour cream, mayonnaise, and seasonings. Stir in the cooled onions.
Refrigerate for at least two hours or overnight. Store the dip covered in the refrigerator for 4-5 days.
Notes
Yields 2 ½ cups.
Chop the onions instead of slicing them. They caramelize faster and provide a nice consistency in the dip.
If the onions start to dry out, add a splash of water or beef broth as needed. Also, a pinch or two of sugar can be added to assist with the caramelization if desired.
The dip can be served immediately but it really shines if the flavors have time to deepen.
