Blend the base: Add cottage cheese, buttermilk, lemon juice, vinegar (if using), ranch seasoning or homemade mix, and Dijon to a blender or food processor. Blend on high until very smooth and fluffy, 30–60 seconds.
Scrape down the sides if needed.
Adjust texture: If it’s too thick, add another splash of buttermilk or water. You’re aiming for a creamy dip—not a runny dressing.
Finish with herbs and oil: Pulse in the fresh herbs. Stream in olive oil for extra silkiness if you like.
Taste and adjust salt, pepper, or lemon.
Portion into cups: Spoon the dip into small containers, filling each about halfway to two-thirds full.
Add dippers: Tuck veggie sticks or crackers into separate compartments if your containers have them. If not, store dippers in small baggies to keep them crisp.
Chill to set: Seal and refrigerate at least 30 minutes. The flavors meld and the dip thickens slightly as it chills.
Serve: Enjoy straight from the cup or transfer to a bowl for sharing.
Garnish with extra dill or a crack of pepper for a fresh finish.
