How to Make Caramelized Onion Dip
Be sure to check the recipe card below for full ingredients & instructions.
- Caramelize Onions: Melt butter in a large skillet over medium-high heat, add onions and cook for several minutes. Then turn the heat down to medium-low and cook the onions for about 20-25 minutes. The only will become soft and will turn a beautiful golden brown color. Caramelizing the onions takes time, but the sweet onion flavor is so worth it! Let the onions cool for 15-20 minutes, otherwise they will melt your dip.
- Make the dip. Mix almost all of the other ingredients together, then stir in the cooled onions. Chives are added last.
- Serve chilled. Let your dip chill out in the fridge for at least an hour. Garnish with fresh chopped chives and serve with your favorite potato chips.
I prefer the sweet Vidalia, but really any type of onion will work. I’ve used yellow and red, but you can also use shallots or a mix of what you like or have on hand.
Yes! you can toss the onions with melted butter or olive oil and bake in the oven on a low heat or even use your Instant Pot.
You absolutely cannot go wrong serving this dip with potato chips. I am quite partial to Ruffles or Lays (with the ridges), but kettle cooked chips are particularly delicious.
You can also serve with bagel chips, pita chips, tortilla chips, pretzels, or crackers. Raw veggies like carrots, bell peppers, or snap peas are a great option, too.
Storage: This dip will last about 3-4 days in an airtight container in the refrigerator. If it looks a little watery, just give it a stir and you’ll be good to go. Feel free to make it a day ahead of your event.
- For a lower calorie dip, replace the sour cream with a low fat variety or Plain Greek yogurt.
- If your onions are becoming dry as they cook, add a couple tablespoons of water to the pan.
- Dairy-based dips should not be left out longer than 2 hours. For food safety, it should be discarded, or refrigerated after this time.
