My neighbor had mentioned making a BLT salad and I wanted to make something similar for a dinner party I was bringing a salad to. After reading a ton of recipes I decided this dressing recipe by Ina Garten would taste the best. I served it with crumbled bacon and cherry tomatoes on whole romaine lettuce leaves. This tastes like ranch dressing but is more lemony, which I really like.
1/2 cup chopped fresh basil leaves, lightly packed
2 tablespoons freshly squeezed lemon juice
11/2 tablespoons Dijon mustard
1 tablespoon good olive oil
2 garlic cloves, chopped
2 1/2 teaspoons kosher salt
1 teaspoon freshly ground black pepper
1 cup good mayonnaise
1/2 cup Greek-style yogurt
1/2 cup buttermilk, shaken
Place the scallions, basil, lemon juice, mustard, olive oil, garlic, salt, and pepper in the bowl of a food processor fitted with the steel blade. Puree for 15 to 20 seconds to make a smooth mixture. Add the mayonnaise, yogurt, and buttermilk and blend until smooth. Transfer the dressing to a container, cover, and refrigerate for 1 hour for the flavors to develop.
