French Onion Dip

I’ll be the first to admit that I have Christmas on the brain. And New Years. And somehow already Valentine’s Day. I just love a good holiday, and I love hosting friends and family over for little parties to celebrate every season! French onion dip is one of my favorite party foods because it really fits any occasion. Whether I’m toasting to the new year or celebrating a happy birthday, this dip is a must make.

What elevates this dip a step above the rest is that it’s homemade, of course! The store-bought stuff really isn’t half bad, but the real deal is just so much better. While caramelizing the onions may require a little bit of patience on your end, the results are so very worth it. I mean really… Is there anything better than a creamy dip loaded with sweet, buttery caramelized onions? I think not.

Besides caramelizing the onions, there really isn’t much to making French onion dip. You just have to toss it all together, serve with your favorite salty potato chips, and enjoy! It’s also pretty great with veggies if you’d like to go a healthier route. Honestly, this stuff is so addictive you can just serve it with a spoon! (Mostly joking).

How to Make French Onion Dip

French onion dip is so easy to make at home! For more detailed instructions, scroll to the bottom of this page where you’ll find the full recipe card.

  1. Caramelize the onions. Add the butter and olive oil to a skillet over medium heat. Add the onions and cook until soft and caramelized. Stir in some sugar when the onions begin to first soften to help quicken the process.
  2. Cool. Remove the caramelized onions from the heat and allow them to fully cool to room temperature.
  3. Mix it all together. Stir together the sour cream, mayonnaise, garlic powder, onion powder and salt. Fold in the cooled onions.
  4. Serve! Place the french onion dip in the fridge and let it get nice and cold. Serve it chilled with your favorite dippers, and enjoy!

Tips for the Best French Onion Dip

Take a quick look at these tips and tricks before you get started:

  • Caramelize the onions. For even more info on how to get perfectly buttery, brown, soft and sweet caramelized onions, check out my how to guide HERE.
  • Let the onions cool. This is SO important. If your onions are warm/hot when you add them in with the other ingredients, they won’t mix well and you’ll risk melting the sour cream and mayo.
  • Use full fat ingredients. Low fat mayo and sour cream will do in a pinch. However, they won’t yield the same thick, creamy results as ingredients with the full fat content.
  • Keep the seasonings simple. All you need to create the best flavor is a little salt, onion powder and garlic powder. Try not to go overboard with seasonings because you can easily overpower the onions.

Storage

Keep french onion dip in the fridge in an airtight container (or serving bowl wrapped tightly with plastic wrap) until you’re ready to serve it. It’ll stay good in the fridge for about 2-3 days.

I do not recommend freezing french onion dip.
