French Onion Dip from scratch is one of our favorite appetizers to make for a BBQ, party and snack. Sweet caramelized onions mixed with spices and herbs.

Homemade French Onion dip is always one of the first things I gravitate towards when at a party. The combination of a salty potato chip and the cool dip is so, so good. 

It tastes like a creamy mixture of a little sweet and salty. The caramelized onions gives it the slightest hint of sweetness and the garlic powder and salt offer a nice salty balance.

It can be tempting to grab a pack of mix at the store but trust me, this homemade recipe is easy to make and worth the few extra steps. 

Why this recipe works

  • This homemade french onion dip is way better than the store bought version filled with additives. 
  • Only needs a few ingredients and always a huge hit! 
Bowl of sour cream, mayo, onions and spices

What you need

Onions – Vidalia, yellow or white work for this recipe. Make sure they are diced small. 

Sour Cream – This is the creamy base. You can use full-fat, low-fat or even Greek yogurt.

Mayonnaise – This adds another layer of flavor.

Garlic Powder – Used to season the dip.

Parsley- Chopped, fresh parsley adds color and a freshness. Chives also work well. 

Salt and Pepper – Added for seasoning. Adjust for taste.

The key to this recipe is the onions! It’s important to get them nice and caramelized before adding to the mixture.

  • Add 2 tablespoons of butter to skillet along with onions. Cook on low for 30-40 minutes. You want them to get golden brown. Allow them to cool in the refrigerator for a few minutes before adding.
  • Stir together sour cream, mayonnaise, spices and parsley. Mix in onions, serve immediately or refrigerate.

How to serve

This onion dip is so good, I could eat it with a spoon but the classic way is with potato chips, especially ruffle style. 

Also try serving with corn chips, bread, cut up vegetables and crackers. 

I have even used this to top a hamburger and mixed with shredded chicken for chicken salad

How to store

This will keep well stored in an air tight container in the refrigerator for up to 5 days. 

I would not recommend freezing because the mayonnaise does not do well when frozen.


  • Make sure to allow enough time for onions to caramelize. Stir them frequently to prevent sticking. If they start to stick to the pan, add a little water or beef broth. 
  • The longer the dip sits, the more the flavors come together. If making for a party, I like to make the night before for maximum flavor.

  1. I used 4 cups of diced onion for this recipe. Thought I’d mention because onions vary greatly in size these days.

  2. 5 stars
