Ranch dressing originated in the United States, specifically in California in the 1950s. It was created by a man named Steve Henson, who owned a dude ranch and began serving the dressing to his guests. The popularity of ranch dressing grew over time and it is now one of the most popular salad dressings in the United States.

Ranch dressing is typically made from a base of buttermilk, mayonnaise and/or sour cream, and various herbs and spices such as parsley, dill, garlic powder, and onion powder. Some recipes also call for additional ingredients like vinegar or lemon juice to add tanginess. The ingredients are usually mixed together until smooth and creamy. Ranch dressing can be used as a dip for vegetables or served over salads or other dishes as a dressing. There are many variations of ranch dressing, with different brands and homemade recipes offering their own unique twists on the classic flavor.

Ranch dressing has become a staple condiment in many households and restaurants across the United States due to its versatility and delicious flavor.
