Why You Will Love This Recipe

This dip is about as simple as it gets. There is no cooking required, no chopping, and no long ingredient list.

The cream cheese makes the dip extra thick and rich, while sour cream keeps it smooth and tangy. Dry onion soup mix provides all the savory onion flavor and seasoning in one convenient ingredient.

It also tastes even better after chilling, so it is an excellent make-ahead appetizer.

The 3 Ingredients

1 cup sour cream
8 ounces cream cheese, softened
1 packet dry onion soup mix, about 1 ounce

Optional Garnishes

Sliced green onions
Fresh chives
Cracked black pepper
Caramelized onions

Ingredient Notes

Sour cream: Full-fat sour cream gives the richest flavor and smoothest texture. Light sour cream also works if you prefer a lighter dip.

Cream cheese: Use block-style cream cheese and soften it before mixing. Softened cream cheese blends much more easily and helps prevent lumps.

Onion soup mix: A standard dry French onion or onion soup mix provides onion, herbs, salt, and seasoning. Because brands vary in saltiness, taste the finished dip before adding any extra seasoning.

How to Make 3-Ingredient French Onion Dip

Place the softened cream cheese in a medium mixing bowl.
Beat with a spoon, whisk, or hand mixer until smooth.
Add the sour cream.
Mix until the cream cheese and sour cream are fully combined.
Sprinkle in the dry onion soup mix.
Stir thoroughly until evenly distributed.
Cover the bowl.
Refrigerate for at least 30 minutes, preferably one hour.
Stir once more before serving.
Garnish with optional chives, green onions, or black pepper.

Why Chilling Makes It Better

You can technically serve the dip immediately, but chilling it makes a noticeable difference.

The dried onions in the soup mix soften as they absorb moisture from the sour cream and cream cheese. At the same time, the seasoning distributes throughout the dip.

After about an hour in the refrigerator, the flavor becomes rounder, richer, and more balanced.

How to Get the Smoothest Texture

Make sure the cream cheese is fully softened before mixing. Cold cream cheese can leave small lumps throughout the dip.

For an especially smooth result, beat the cream cheese first, then gradually add the sour cream.

A hand mixer will make the dip lighter and fluffier, while mixing by hand gives it a denser, classic texture.

How to Adjust the Thickness

If the dip is too thick, add one or two tablespoons of sour cream until it reaches your preferred consistency.

If it seems too thin, refrigerate it for 30 to 60 minutes. Cream cheese firms as it chills and helps thicken the dip naturally.

You can also add a little more softened cream cheese when you want a very thick dip for spreading on crackers or sandwiches.

Easy Variations

For a lighter French onion dip, replace some of the sour cream with plain Greek yogurt.

For extra onion flavor, stir in chopped green onions or a spoonful of caramelized onions.

For a smoky version, add a small pinch of smoked paprika.

For spicy onion dip, add cayenne pepper, hot sauce, or crushed red pepper flakes.

For bacon French onion dip, fold in cooked crumbled bacon just before serving.

For cheesy onion dip, mix in shredded sharp cheddar or Parmesan.

What to Serve with French Onion Dip

Classic ridged potato chips are one of the best choices because they are sturdy enough for the thick dip.

You can also serve it with tortilla chips, pretzels, crackers, pita chips, bagel chips, or toasted baguette slices.

For a fresh option, serve the dip with celery sticks, baby carrots, cucumber slices, bell peppers, broccoli, or cauliflower.

It also works as a spread for sandwiches, burgers, wraps, and baked potatoes.

Can You Make It Ahead?

Yes. This dip is actually better when prepared ahead because the onion flavor develops during refrigeration.

Make it several hours or even one day before serving and store it covered in the refrigerator.

Before serving, stir it well and let it sit at room temperature for about 10 minutes if it feels too firm.

Party Serving Tips

For game day or parties, transfer the dip to a shallow serving bowl and sprinkle chopped chives or green onions over the top.

Place chips and vegetables around the bowl on a large platter for an easy appetizer board.

If the dip will be sitting out, put out a smaller portion and refill it from the refrigerator as needed rather than leaving the entire batch at room temperature for hours.

Storage

Store leftover French onion dip in an airtight container in the refrigerator for up to three to four days.

Give it a good stir before serving again because a small amount of liquid may separate during storage.

Do not leave dairy-based dip at room temperature for more than two hours, or more than one hour in very hot conditions.

Freezing is not recommended because sour cream and cream cheese can separate and become grainy after thawing.
