Ingredients You’ll Need
To make this luscious dip, you’ll need just a handful of straightforward ingredients. Each component plays a special role, whether it’s building depth of flavor, creating that smooth and creamy texture, or adding a bit of subtle spice for balance.
- Olive oil: For gently caramelizing the onions to enhance their natural sweetness.
- Chopped onion: The star of the dip, which transforms beautifully when slowly cooked to golden perfection.
- Kosher salt: Divided to season both the onions during caramelization and the final dip.
- Sour cream: Adds tanginess and a velvety texture to the dip’s base.
- Mayonnaise: Provides creaminess and helps bind all flavors together beautifully.
- Garlic powder: A subtle savory punch that works perfectly with the onions.
- Ground white pepper: For gentle heat without overpowering the delicate flavor.
How to Make Homemade French Onion Dip from Scratch Recipe
Step 1: Gather Your Ingredients
Start by assembling everything you need. Having all ingredients prepped and ready makes the whole process smooth, and you can appreciate each step more fully.
Step 2: Caramelize the Onions
Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the chopped onions along with 1/4 teaspoon of kosher salt. Stir occasionally as the onions slowly soften and turn a rich golden brown, which will take about 20 minutes. This patient caramelization is what brings out the dip’s unmistakable sweet and savory depth. Once done, remove from heat and let the onions cool for about 5 to 10 minutes to avoid breaking down the creamy base later.
Step 3: Mix the Creamy Base
In a bowl, combine 1 cup sour cream and 1 cup mayonnaise. Stir in 1/2 teaspoon garlic powder, 1/4 teaspoon ground white pepper, and the remaining 1/2 teaspoon of kosher salt. This mixture forms the luscious foundation that blends smoothly with the rich onions.
Step 4: Combine Onions and Creamy Mixture
Once the onions have cooled, gently fold them into the creamy base. Stir until all parts are well combined, making sure those golden caramelized onions are evenly distributed. This step locks in every bit of flavor and texture that makes the dip unforgettable.
How to Serve Homemade French Onion Dip from Scratch Recipe

Garnishes
Elevate your dip with thoughtfully chosen garnishes. A sprinkle of freshly chopped chives or finely diced green onions not only adds a burst of color but also a fresh bite that complements the caramelized onions. If you want a bit of extra indulgence, a tiny drizzle of browned butter over the top can send this dip to gourmet-level flavor.
Side Dishes
This dip pairs brilliantly with classic potato chips, pita chips, or fresh vegetable sticks like crisp celery, carrots, and bell peppers. The creamy dip provides a satisfying contrast to crunchy sides, making it perfect for casual snacking or as part of a larger appetizer spread.
Creative Ways to Present
Instead of just serving in a bowl, consider hollowing out a small bread bowl to fill your dip for a rustic, inviting presentation. Or create individual servings in small ramekins topped with a sprinkle of smoked paprika or fresh herbs for a charming party appetizer. The dip’s rich texture means it also works great as a spread on sandwiches or wraps for an onion-flavored boost.
Make Ahead and Storage
Storing Leftovers
This dip holds up wonderfully when stored properly. Transfer it to an airtight container and keep it refrigerated for up to 3 days. The flavors actually marry even more beautifully after some time, making it perfect to prepare ahead for gatherings.
Freezing
While freezing helps preserve foods long term, this particular Homemade French Onion Dip from Scratch Recipe is best enjoyed fresh or refrigerated. Freezing can alter the texture of the sour cream and mayonnaise, causing separation, so it’s not recommended for this recipe.
Reheating
This dip is generally served cold or at room temperature, so reheating isn’t typically needed. If you do prefer it slightly warmed, gently heat it in a microwave-safe dish in short bursts, stirring frequently to avoid breaking the creamy texture.
FAQs
Can I use yellow onions instead of the regular chopped onions?
Absolutely! Yellow onions caramelize well and are slightly sweeter, which enhances the flavor profile of the dip beautifully. Just make sure to cook them slowly to bring out their sweetness fully.
Is there a way to make this dip vegan?
Yes, you can swap sour cream and mayonnaise with plant-based alternatives such as vegan sour cream and vegan mayo. Caramelized onions remain the star, so the dip will still taste fantastic with those adjustments.
How long does it take to caramelize the onions properly?
To get that deep golden brown color and rich flavor, plan on cooking onions for about 20 minutes over medium heat. Patience is key here for the best-tasting dip.
Can I prepare the onions ahead of time?
Definitely! You can caramelize the onions up to a day in advance and refrigerate them in a sealed container, making the final assembly quick and easy before serving.
What can I use if I don’t have garlic powder?
A small amount of finely minced fresh garlic works as an alternative, but add it in the last few minutes of caramelization to avoid burning and bitterness.
