Ingredients You’ll Need

One of the best things about this recipe is how easily you can find everything at your local grocery store. Each ingredient plays an important role in creating the dip’s signature creamy texture and savory flavor.

1. Sour Cream – 2 cups

Sour cream is the foundation of this French onion dip. It provides a thick, creamy consistency with a slight tanginess that balances the savory onion seasoning. For the best texture, use full-fat sour cream. You can also use reduced-fat sour cream if you prefer a lighter version.

2. French Onion Soup Mix – 1 packet (about 1 ounce)

This is the ingredient that gives the dip its unmistakable French onion flavor. The seasoning packet typically contains dried onions, salt, herbs, and other savory seasonings. It adds plenty of flavor without requiring you to chop, cook, or caramelize fresh onions.

3. Mayonnaise – ½ cup

Mayonnaise adds richness and makes the dip extra smooth and creamy. It also balances the tanginess of the sour cream, creating a deliciously satisfying consistency. Regular mayonnaise works wonderfully, although you can use a lighter variety if desired.

How to Make 3-Ingredient French Onion Dip

Making this homemade French onion dip couldn’t be easier. You don’t need any special kitchen equipment, and the entire preparation process takes only a few minutes.

Step 1: Prepare Your Ingredients

Before you begin, gather your sour cream, French onion soup mix, and mayonnaise.

Measure the sour cream and mayonnaise carefully so that the finished dip has the right balance of creaminess and flavor.

Place the sour cream and mayonnaise in a medium-sized mixing bowl. Make sure the sour cream is well stirred and smooth before adding the seasoning.

Step 2: Add the French Onion Soup Mix

Open the packet of French onion soup mix and sprinkle it evenly over the sour cream and mayonnaise.

Using a spoon or spatula, begin mixing everything together. Stir slowly at first to prevent the dry seasoning from scattering outside the bowl.

Continue mixing until the seasoning is evenly distributed throughout the creamy mixture. Pay attention to the sides and bottom of the bowl to make sure no dry seasoning remains unmixed.

The dip should have a consistent appearance, with little pieces of dried onion distributed throughout.

Step 3: Mix Until Smooth and Creamy

Continue stirring until all three ingredients are fully combined.

The mixture should become thick, creamy, and easy to scoop. If you notice a few small lumps from the seasoning, don’t worry. The dried onion pieces will soften as the dip rests in the refrigerator.

Taste a small amount if desired, but remember that the seasoning mix will continue releasing flavor as it sits.
