Ingredients

2 tbsp. unsalted butter
2 tbsp. vegetable oil
2 large yellow onions (1 3/4 lb. total), thinly sliced
Kosher salt
1/2 c. (4 oz.) cream cheese, room temperature
1/2 c. (4 oz.) sour cream
1/3 c. mayonnaise
Freshly ground black pepper
2 tbsp. sliced chives
Potato chips, such as Ruffles, for serving

Instructions

Step 1: In a large skillet over medium heat, melt the butter and swirl in the vegetable oil. Add the thinly sliced onions and 1/2 teaspoon of kosher salt. Cook, stirring occasionally, until the onions begin to soften and break down, about 10 to 12 minutes.
Step 2: Reduce the heat to medium-low and continue cooking the onions, stirring occasionally, until they are golden and deeply caramelized, about 40 minutes more. Transfer the caramelized onions to a medium bowl and let them cool completely.
Step 3: Stir in the cream cheese, sour cream, and mayonnaise until the mixture is smooth and well combined. Season with salt and freshly ground black pepper to taste.
Step 4: Top the dip with sliced chives for a fresh, mild onion flavor. Serve immediately with your favorite potato chips.

Tips & Variations

Use a heavy-bottomed skillet to ensure even cooking and prevent onions from burning.
For a tangier flavor, add a teaspoon of Worcestershire sauce or a splash of lemon juice to the dip before serving.
Try substituting Greek yogurt for sour cream for a lighter version with a slightly tangy taste.
Caramelizing the onions low and slow is key for deep flavor; don’t rush this step.

Storage

Store the caramelized onion dip in an airtight container in the refrigerator for up to 3 days. Before serving, let it sit at room temperature for about 15 minutes, and give it a good stir. It’s best enjoyed fresh but can be gently stirred to restore creaminess if it thickens in the fridge.
