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. 

If you enjoy appetizer dips be sure to try this popular beer cheese and sausage dip, fruit dip, Knorr spinach dip, crack dip, and chipped beef dip. 

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! 

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.

Tips

• 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.
