Add 1 cup cottage cheese and 1/2 cup plain Greek yogurt to a blender or food processor. Blend until completely smooth, scraping down the sides as needed.
Add Seasoning
Add 2 tablespoons ranch seasoning mix and 1 tablespoon lemon juice to the blended mixture. Blend again until fully combined and creamy.
Adjust Consistency
If the dip dressing is too thick, blend in a splash of water at a time until it reaches your desired consistency (thicker for dip, thinner for dressing)
Taste and Season
Taste and add salt if needed or extra ranch seasoning for a stronger flavor.
Chill
Transfer to a jar or airtight container and refrigerate for at least 30 minutes before serving.
