Notes
This recipe makes approximately 10 fluid ounces. A serving is 2 tablespoons.
For a spicy version, add some ground chipotle powder.
Like your ranch more tangy? Add extra lemon juice, lemon zest, or a splash of apple cider vinegar.
Feel free to double up on the herbs and spices, or use fresh herbs instead of dried.
Make it thicker or thinner by adjusting the amount of water.
Add avocado for an even creamier dressing.
Store the dressing in a glass container in the refrigerator for up to a week. It will thicken over time, so you may need to add a little water and shake well before using.
