Before You Start

How to Make 3-Ingredient French Onion Dip

Step 1

In a medium mixing bowl combine:

• Sour cream
• Mayonnaise

Whisk until completely smooth and creamy.

Step 2

Add the dry French onion soup mix.

Stir thoroughly until evenly incorporated.

Step 3

Cover the bowl.

Refrigerate for at least 30 minutes.

For the best flavor, chill for 4 hours or overnight.

Step 4

Stir well before serving.

Transfer to a serving bowl and garnish with fresh chives or green onions if desired.

Serve chilled.

Why This Recipe Works

The dehydrated onions slowly absorb moisture from the sour cream, becoming soft while releasing concentrated savory flavor throughout the dip.

Mayonnaise contributes a silky richness while sour cream adds brightness and tang, creating the perfect creamy consistency for chips, crackers, vegetables, and pretzels.

The longer the dip chills, the better the flavor becomes.

Expert Tips

• Always whisk the dairy ingredients together before adding the soup mix.
• Refrigerate at least 30 minutes before serving.
• Overnight chilling produces the richest flavor.
• Stir again before serving for a perfectly creamy texture.
• Garnish immediately before serving for the freshest appearance.
