Homemade cilantro lime ranch dressing is made with buttermilk, ranch seasoning, and easy roasted tomatillos. Drizzle this over a taco salad, use a creamy taco sauce, or serve it with spicy sweet potato chips for an appetizer.
Toss the chopped tomatillos with the olive oil in a small baking dish. Roast for 15 minutes and let cool completely before you add them to the dressing.
Prepare the Dressing:
Wash and dry the cilantro. Remove the stems and add the leaves to the bowl of a food processor.
Prepare the jalapeño by remove the top and slicing in half length-wise. Use a spoon to scoop out and discard the inside ribs and seeds. Roughly chop the pepper into large chunks and add to the food processor bowl.
Squeeze the juice of the lime into the food processor bowl. Add the minced garlic and ranch seasoning.
Add the cooled tomatillos to the food processor, place the lid on top and pulse the fresh herbs and veggies together until minced.
Add the buttermilk and the mayonnaise to the food processor. Pulse until smooth.
Store the ranch dressing an air-tight container in the fridge for up to 5 days.
