Yes — several ready-to-eat dips list dairy (e.g., 'Contains: Milk' or 'made with real milk and cream'). Dry seasoning mixes are typically meant to be mixed with sour cream, so they are usually used with dairy when prepared as directed.
Listings commonly emphasize rich, savory or bold onion flavor and a creamy, smooth texture. Typical phrases include 'rich and savory,' 'creamy, bold onion flavor,' and 'cool and creamy' to describe taste and mouthfeel.
Seasoning packets are usually mixed with sour cream (or water per instructions) to make a creamy dip. They can also be used as a seasoning for meats and vegetables as an alternative to dip preparation.
Listings repeatedly suggest serving with chips, crackers, and vegetables. Some also recommend toppings like crumbled bacon and fresh scallions as quick garnish ideas.
Single mix packets commonly weigh about 1.1–1.25 ounces. Case formats are also sold—for example, a case listing shows twelve 1.1 oz packets with a total net weight of 13.2 ounces.
