What is French Onion Dip? A quick french onion dip is often made with onion soup mix and sour cream, however, making it homemade with real caramelized onions makes it 1000x better. It takes a bit of extra time but I promise, it’s worth it.

How to Make French Onion Dip

This dip is easy to prepare with just 2 simple steps. The little extra time spent preparing this dip is well worth it in the end!

  1. Saute chopped onions until soft and lightly caramelized. Low and slow is the trick here!
  2. Combine the remainder of the ingredients and add the cooled onions.

Cover tightly and refrigerate at least two hours before serving the dip chilled.

What to Serve with It?

The original dippers for French Onion Dip have always been plain potato chips. But there are so many delicious options to serve with it!

  • Veggies: celery sticks, button mushrooms, broccoli, and cauliflower florets are a real hit and look spectacular on a serving platter.
  • Bread: mini-toasts, crostini, pretzel rods, breadsticks, crackers, and chips pair perfectly with this dip.

How Long Does French Onion Dip Last?

French Onion Dip will last about 7 days in the refrigerator if it is kept tightly covered (as long as the expiration date on your sour cream is still ok). It doesn’t freeze well because the sour cream will separate, making it grainy once it thaws.

    1. That is definitely the danger when it comes to yummy dips! They seem to “disappear” quickly

  1. A delicious and easy to make french onion dip recipe i have ever tried so far. Thanks for sharing this recipe with all of us. Also do check out my special french onion dip recipe as well. 5 stars

  2. My dip didn’t turn out so good. I don’t think it’s the recipe (my husband has commented that dinners have been over-the-top delicious lately – the change? I’ve been using your site, so thank you!!), I really think it was my fault. I’m not intuitive in the kitchen. I was afraid of overcooking the onions so I sautéed them on low (on my electric flattop stove) and it took about 45-50 minutes. I think cooking them that long brought out way too much sweetness in the onions because the dip was super sweet, not savory like I expected onion dip to be. What do you think?

    1. It sounds like your onions were caramelized perfectly, they do take very long to become golden without browning but will get sweeter the longer they cook. It could also be the variety of onion you used (I used a regular white onion with the yellow-ish papery skin).

      I hope that helps!

    1. Apologies for the confusion Jackie! We used butter (we tested both but found butter had better flavor). Enjoy!
