Homemade French Onion Dip Recipe

I absolutely love this recipe because the sweet, caramelized onions create a depth of flavor that makes this dip completely irresistible. Plus, the combination of sour cream and mayo creates the perfect creamy base that’s a total crowd-pleaser at any gathering!

I adore preparing the ultimate snack without giving up on taste, and my Homemade French Onion Dip accomplishes that perfectly. It contains the richness of unsalted butter; the sweetness of finely chopped yellow onions, which have been caramelized to perfection with a hint of sugar; and a blend of sour cream and mayonnaise that is nothing short of divine.

The Worcestershire sauce and the pinch of garlic and onion powder in this dip make it a real umami bomb, while the fresh chives add a nice, herby note to finish.

Ingredients

Yellow onions have a wealth of antioxidants; they also have a wealth of sweetness and deepness.

Butter (Unsalted): Contributes to creaminess and allows for control over the amount of salt.

Tanginess and a smooth texture come from sour cream.

Mayonnaise: Enriches dip’s consistency and mouthfeel.

Worcestershire Sauce: Contributes umami and layered flavors.

Powdered garlic: imparts a mild, savory flavor of garlic.

Onion powder strengthens the flavor of onions but doesn’t let it take over.

Pepper Black: Provides a slight punch and associates flavors.

Substitutions and Variations

2 tablespoons unsalted butter: For a different flavor, substitute olive oil or ghee.
1 cup sour cream: Substitute with Greek yogurt or crème fraîche. Both provide a similarly creamy texture but have a different flavor profile.
1/2 cup mayonnaise: Use plain unsweetened yogurt or a vegan mayonnaise for a lighter option to make this a healthier alternative.
1/4 teaspoon sugar: Swap in honey or agave syrup for a natural, sweet alternative.
Finely chopped fresh chives: If you do not have fresh chives, finely chop some green onion. If you do not want to use onion of any kind, leave this out.

Pro Tips

1. Caramelization Tip For deeply caramelized onions, be patient and stir frequently. If the onions are browning too quickly, reduce the heat and add a splash of water to prevent burning and sticking.

2. Ingredient Quality Use high-quality mayonnaise and sour cream for the best flavor. Full-fat options generally provide the best texture and richness for the dip.

3. Flavor Depth Enhance the depth of flavor by adding a splash of balsamic vinegar or a pinch of smoked paprika to the onions during the last few minutes of caramelization.

4. Cooling Technique To speed up the cooling of caramelized onions, spread them thinly on a baking sheet. This will disperse the heat more quickly, allowing you to mix your dip sooner.

5. Flavor Enhancement For a bolder onion flavor, consider adding a tablespoon of finely chopped fresh onions or shallots along with the caramelized onions. This adds a fresh kick to the dip.
