x 1⅜-ounce envelope onion soup mix

Onion soup mix is a dehydrated seasoning blend consisting primarily of dried minced onions, salt, corn starch, hydrolyzed vegetable protein, beef or chicken broth powder, and various spices including garlic, turmeric, and bay leaf. This commercially produced mixture is designed to reconstitute quickly into an instant soup or serve as a multi-purpose seasoning base. The standard 1⅜-ounce envelope typically contains ingredients proportioned to create one serving of soup when combined with boiling water, or to flavor casseroles, sauces, and other dishes. The blend emerged as a convenience product in mid-20th century American kitchens, becoming a staple ingredient in both everyday cooking and vintage recipe collections.

Onion soup mix functions as both a quick soup base and a versatile seasoning ingredient in American home cooking. Mixed with boiling water and sour cream or beef broth, it produces instant French onion soup or a creamy onion dip. The mix is frequently incorporated into casseroles, pot roasts, meatloaves, and gravy bases to add savory depth. It is commonly used to season beef stews, chicken dishes, and vegetable preparations. The ingredient reduces preparation time substantially by eliminating the need to caramelize fresh onions, making it particularly valuable in quick weeknight cooking and as a flavor enhancer in slow-cooker recipes.
