This bright, herbaceous vinaigrette comes together in just five minutes with a simple whisk. Fresh lemon juice and basil create a sunbeam of flavor that will make you forget store-bought dressings exist. It's the perfect versatile dressing for salads, grain bowls, grilled proteins, and roasted vegetables.
For best results, use fresh lemon juice and fresh basil—bottled juice and dried basil will not yield the same bright flavor. Adding the oil too quickly is the most common mistake; a slow, steady stream while whisking ensures a stable emulsion. The dressing keeps in the refrigerator for up to 2 days, but the basil may darken over time, so it's best to add the basil just before serving for the prettiest presentation. For a creamy variation, whisk in 2 tablespoons of Greek yogurt or sour cream. For a spicy kick, add a pinch of red pepper flakes or a slice of fresh jalapeño with the basil.
