Ingredients You’ll Need

The beauty of this French Onion Dip is in its simplicity: every ingredient brings something essential, whether it’s sumptuous creaminess, mouthwatering umami, or that signature golden-brown sweetness. Don’t skip a single part—each one helps build layers of crave-worthy flavor and the perfect texture for scooping!

Unsalted butter (2 tablespoons): This helps caramelize the onions to golden perfection, giving a rich base to the dip.
Large yellow onion, finely chopped (1): The heart of the dip, the onion brings sweet and savory complexity after a slow caramelization.
Salt (1/2 teaspoon): Essential for drawing out the onion’s moisture and amping up all the flavors.
Black pepper (1/4 teaspoon): Adds gentle warmth and a touch of earthy depth.
Sugar (1/2 teaspoon): A pinch of sugar helps those onions develop rich, golden notes during cooking.
Worcestershire sauce (1 teaspoon): Just a splash for irresistible umami and tangy complexity.
Garlic powder (1/2 teaspoon): Rounds out the savoriness—you’ll miss it if it’s not there!
Onion powder (1/2 teaspoon): Double-downs on the onion profile for an all-around flavor punch.
Sour cream (1 1/2 cups): The creamy base that makes each bite so deliciously smooth; Greek yogurt works as a swap for a lighter option.
Mayonnaise (1/2 cup): Adds extra silkiness and richness, balancing the twang of the sour cream.
Chopped chives (optional): A burst of color and fresh, mild onion flavor as the perfect garnish.

How to Make French Onion Dip

Step 1: Caramelize the Onions

Start by melting the unsalted butter in a large skillet set over medium heat, and add your beautifully chopped onion along with salt, pepper, and that touch of sugar. Stir occasionally, allowing the onions to break down, soften, and turn a deep, glorious golden brown—this slow transformation can take 25 to 30 minutes, so be patient! Caramelization is the key to those signature layers of flavor in classic French Onion Dip.

Step 2: Cool the Onions

Once your onions are perfectly caramelized, remove the skillet from the heat. Let the onions cool completely (seriously, don’t rush this step—mixing hot onions into the dairy can lead to a runny dip, and nobody wants that!).

Step 3: Mix the Creamy Base

While the onions are cooling, grab a mixing bowl and stir together the sour cream, mayonnaise, Worcestershire sauce, garlic powder, and onion powder. Whisk everything until the mixture is smooth, creamy, and well blended.

Step 4: Fold in the Onions

Once the onions have cooled, gently stir them into your creamy base. Mix thoroughly to make sure every bite of your French Onion Dip is bursting with silky, caramelized goodness.

Step 5: Chill

Cover the bowl and refrigerate for at least an hour before serving. This gives the flavors time to mingle and enhance each other, resulting in an even richer, more delectable dip. If you can wait overnight, it gets even better!

Step 6: Garnish and Serve

Just before serving, sprinkle with chopped chives for a pop of color and fresh taste. Then dive in with your favorite chips, crackers, or veggies—enjoy the oohs and aahs from everyone who tries it.

How to Serve French Onion Dip

Garnishes

Finish your French Onion Dip with a sprinkle of chopped chives or fine green onions for both color and a delicate fresh note. If you want more texture and richness, crisp up shallots or thinly sliced fried onions and scatter them on top—your dip will look and taste extra fancy.

Side Dishes

Of course, nothing beats classic salty potato chips for scooping, but don’t stop there! Serve with sliced crisp veggies like carrots, celery, bell peppers, or cucumbers. Crackers, pretzel crisps, and even thinly sliced baguette rounds turn this creamy dip into an instant party platter favorite.

Creative Ways to Present

Get playful: You can hollow out a round sourdough loaf and fill it with your luscious French Onion Dip, using the bread “lid” and chunks for dipping. For gatherings, divide into individual cups or mason jars for less mess and easy serving. Or pipe little dots onto cucumber slices or crispy potato bites for passed hors d’oeuvres with flair.

Make Ahead and Storage

Storing Leftovers

If you’re lucky enough to have leftover French Onion Dip, simply scoop it into an airtight container and refrigerate. It’ll stay thick, creamy, and full of flavor for up to 4 days—just give it a quick stir before serving again.

Freezing

While technically possible, I don’t recommend freezing this dip. The sour cream and mayonnaise can separate when thawed, changing the texture. For best results, enjoy it fresh or make just what you need for each event.

Reheating

French Onion Dip is meant to be enjoyed cold or at room temperature, so there’s no need to reheat. If it has been in the fridge, take it out 10–15 minutes before serving for the creamiest consistency and best flavor.

FAQs

Can I make French Onion Dip ahead of time?

Absolutely! In fact, letting the dip rest in the fridge for several hours or overnight makes the flavors even more balanced and robust, so it’s perfect for prepping before a party.

Is there a way to lighten up this dip?

Yes! Substitute some or all of the sour cream with Greek yogurt for a tangier, lighter version. You’ll keep the creamy texture but cut down on fat and calories.

What should I do if my dip is too runny?

Sometimes overly warm onions or thinner sour cream can make the dip a bit loose. Let it chill longer—the mixture will firm up as it cools. You can also add a little more mayonnaise or Greek yogurt to thicken it up.

Can I use red or white onions instead of yellow?

While you can experiment with other onions, yellow onions lend the perfect balance of sweetness and savoriness after caramelization. Red onions will be more pungent, and white onions are sharper, so expect a slightly different but still tasty result.

How long can I keep French Onion Dip in the fridge?

Stored properly in an airtight container, French Onion Dip will stay fresh for up to 4 days. Give it a good stir each time you serve for the creamiest texture.
