This incredibly easy 3-Ingredient French Onion Dip is the ultimate crowd-pleasing party appetizer! Rich sour cream and velvety mayonnaise are combined with savory onion soup mix for a chilled, restaurant-quality snack that takes seconds to prepare.
Mix the Base: In a medium mixing bowl, combine the sour cream and mayonnaise. Whisk them together thoroughly until the mixture is completely smooth, creamy, and well blended.
Add the Flavor: Pour the packet of dry onion soup mix directly into the dairy base. Stir the mixture vigorously until the dehydrated onions and spices are fully evenly distributed throughout the bowl.
Chill and Hydrate: Cover the bowl tightly with plastic wrap or a fitted lid. Refrigerate the dip for at least 30 minutes to allow the dehydrated onions to soften and the flavors to fully develop.
Serve: Remove the bowl from the refrigerator and give the dip one final, gentle stir. Serve chilled alongside your favorite sturdy potato chips, crackers, or a platter of fresh vegetables!
Notes
Pro-Tip: For the absolute best flavor development, try to use a full-fat sour cream and a high-quality, real egg mayonnaise! Low-fat or fat-free dairy alternatives contain high amounts of water that can make your final dip feel thin, soupy, and lacking in that signature richness.
