How This Onion Dip Recipe Developed
Remember that onion dip you made as a kid? It was a big tub of sour cream mixed with a Lipton Onion Soup Mix? Well, at least mine was. It was super easy and also tasty. However, it's not gluten-free. Lipton Onion Soup Mix contains wheat. And if you have celiac disease like I do, that means no more easy onion dip.
And while in the past I have found a Certified Gluten-Free version of Onion Soup Mix from Goodman's or even Mom's Place (and it's what I use in this gluten-free pot roast), or I've even bought pre-made versions...I decided to up my game and try a homemade onion dip.
Because I think EVERYTHING tastes better homemade, and it gives you a sense of pride when YOU have made it yourself! (Like my gluten-free croissants. Probably one of my proudest moments)
About The Onion Deip Recipe
And this onion dip does not use any pre-packaged dry soup mix - just real, caramelized onions! PLUS it could easily be made lactose-free or dairy-free.
These flavors are ten times better than the onion soup mix dip I remember as a child. Plus, it doesn't take long to make, so it's still an easy dip you can make for a party or get-together.
The only difference is that you have to cook the onions. Besides that, it's just mixing everything together and letting it refrigerate.
Ingredients You Will Need For Gluten & Dairy Onion Dip
-Sour Cream (lactose-free or dairy-free, as needed)
-Onions (sweet or yellow onions work fine)
-Butter or Olive Oil
-Ruffles Potato Chips (because you just got to!)
How To Make Gluten-Free Onion Dip
This recipe is super easy! You'll caramelize the onions by cooking them low and slow on the stovetop in butter or olive oil. Once they are reduced, you'll add it to the sour cream, mayo, and spices, and mix together. Then you leave it to meld together overnight in the refrigerator.
Can I Make This Onion Dip Lactose-Free or Dairy-Free?
Yes, you can! To make this onion dip lactose-free, substitute Lactaid or Green Valley sour cream and use olive oil instead of butter. To make this onion dip dairy-free, substitute Kite Hill Sour Cream and use olive oil instead of butter. Or, feel free to use your own favorite dairy-free substitute.
Tips For Making Onion Dip
Onions: To caramelize onions, you want to cook them low and slow. Keep the heat on medium-low to low heat and watch them so they don't burn. This is the long game, so take your time!
Let It Sit: The longer this dip sits in the refrigerator, the better it tastes. Even the second day we noticed it was even better than just sitting in the fridge for a few hours. The flavors have more time to meld together, so if you can let this onion dip sit overnight, you'll love it even more.
How To Store Gluten-Free Onion Dip
Store this dip in the refrigerator in a sealed container or covered and use it within a week. The longer it sits, the better it tastes, but I'd eat it within a few days for best results!

Homemade Gluten-Free Onion Dip (Lactose-Free & Dairy-Free Option)
- 3 tablespoons of butter (use olive oil for dairy-free option)
- 2 cups onions, chopped (about 1-2 small yellow onions)
- ¼ teaspoon kosher salt
- 1 ½ cups sour cream (use dairy-free or lactose-free for dairy-free option)
- ½ cup mayonnaise
- ½ teaspoon onion powder
- ¼ teaspoon freshly ground black pepper
- ¼ teaspoon cayenne pepper
- ½ teaspoon kosher salt
- Ruffles potato chips, for serving
- Fresh parsley, for garnish
First, prep the onions. Melt butter or oil in a saute pan over medium heat. When its hot, add the onions and ¼ teaspoon kosher salt. Cook for 5 minutes over medium heat, then lower to medium-low. Cook the onions until they are caramelized, about 20-25 minutes. They should soften and turn a golden brown color. If you notice them burning, lower the heat more.
Remove the onions from heat and set them aside to cool.
In a large bowl, mix together the sour cream, mayonnaise, additional kosher salt, black pepper, onion powder, and cayenne pepper. Add the cooled onions and stir until just combined.
Refrigerate for 3 hours (or overnight, for better flavor!) and stir again before serving. Enjoy with potato chips, veggies, and a sprinkle of parsley on top. Use within a week.
To make this onion dip lactose-free, substitute Lactaid or Green Valley sour cream and use olive oil instead of butter. To make this onion dip dairy-free, substitute Kite Hill Sour Cream and use olive oil instead of butter. Or, feel free to use your own favorite dairy-free substitute.
