The sound of a crinkling chip bag being opened at a family gathering instantly triggers memories of everyone crowding around the snack table.
This homemade French Onion Soup Dip captures that nostalgia perfectly, delivering a richness and depth you simply cannot find in the plastic tubs at the grocery store.
Why This French Onion Soup Dip is a Party Staple
It requires only three accessible ingredients that you likely already have in your pantry or can grab at the corner store.
The combination of mayonnaise and sour cream creates a luxuriously smooth texture that coats every chip without breaking it.
You can whip this appetizer up moments before guests arrive, and they will assume you spent hours slow-cooking caramelized onions for the base.

What You’ll Need for French Onion Soup Dip
Gather these simple items to create the ultimate savory snack:
- Sour Cream: Full-fat varieties work best here to provide a thick, sturdy base that isn’t too watery.
- Mayonnaise: Use a quality whole-egg mayonnaise to add a silky mouthfeel and balance the tang of the sour cream.
- French Onion Soup Mix: A standard packet of dry soup mix provides all the seasoning and dehydrated onion pieces you need.
My Method for French Onion Soup Dip
- Start by selecting a medium-sized mixing bowl that gives you enough room to stir vigorously without spilling. Add the sour cream, mayonnaise, and the packet of French Onion Soup Dip mix into the bowl. Using a spatula or a large spoon, fold the ingredients together thoroughly. You want to ensure that the dried soup mix is evenly distributed throughout the creamy base so that you don’t end up with pockets of dry powder or unseasoned sour cream.
- Once combined, it is absolutely essential to let the mixture rest before serving. Cover the bowl with plastic wrap or a tight lid and place it in the refrigerator for at least 15 to 20 minutes, though an hour is even better. During this time, the dehydrated onions from the soup mix will absorb moisture from the cream and soften significantly, releasing their savory flavor into the dip. If you skip this step, the dip will have a gritty, crunchy texture rather than the smooth, creamy consistency you want.
- After the resting period, give the dip one final stir to incorporate any liquid that may have separated slightly. Transfer the mixture to a serving bowl and garnish with fresh chives if you like a pop of color. Arrange your favorite sturdy chips or vegetable sticks around the bowl and serve immediately while it is still cool and refreshing.
My Best Tips for Perfect French Onion Soup Dip
Always choose full-fat dairy products because low-fat versions often contain stabilizers that can make your French Onion Soup Dip watery.
If you have the time, making this a day in advance allows the flavors to meld together for an even bolder taste.
For a slightly tangier kick, I sometimes squeeze a small wedge of fresh lemon juice into the mixture just before serving.
How to Serve This French Onion Soup Dip
Rigid, crinkle-cut potato chips are the traditional vehicle for this heavy dip since they hold up well against the thick texture.
I also love balancing the savory richness of the French Onion Soup Dip with crisp, fresh vegetables like celery sticks, carrot batons, and cucumber slices.
