-3/4-ounce package dry onion soup mix

Dry onion soup mix is a dehydrated seasoning blend composed primarily of minced or powdered dried onions combined with salt, spices, and sometimes beef or vegetable bouillon powder. Originating in the mid-20th century as a convenience product, this blend was developed to simplify the preparation of French onion soup and other savory dishes. The mixture typically contains dried onion pieces (the predominant ingredient), salt, corn starch, sugar, beef stock powder, and spices such as thyme, bay leaf, parsley, and sometimes garlic powder. The flavor profile is distinctly savory and umami-forward, with a pronounced onion essence that intensifies when hydrated.

Dry onion soup mix is primarily used to prepare onion soup quickly by reconstituting the blend in hot water or broth. Beyond soups, it serves as a seasoning base for pot roasts, beef stews, and braised dishes, where its concentrated flavor enhances cooking liquids. The mix is also used as a dry rub for meats, incorporated into dips (mixed with sour cream or cream cheese), sprinkled over roasted vegetables, or stirred into ground meat for burgers and meatballs. Home cooks and food service operations value it for its convenience and consistent flavor, though some preparations call for modifying the salt content depending on other ingredients used.
