Blend the base: Add cottage cheese, lemon juice, and Greek yogurt (if using) to a blender or food processor. Blend until smooth and creamy, about 20–30 seconds.
Add the ranch flavors: Sprinkle in dill, parsley, chives, garlic powder, onion powder, salt, and pepper.
Pulse a few times to combine. Taste and adjust seasoning.
Adjust the texture: For a thinner dip or dressing, blend in 1–2 tablespoons milk or water until it reaches your preferred consistency.
Rest for flavor: Let it sit for 10–15 minutes in the fridge. This helps the herbs bloom and the flavors meld.
Serve: Pair with carrots, cucumbers, bell peppers, cherry tomatoes, celery, crackers, or use as a sandwich spread.
