Bright, herby, colorful, and delicious, pesto sauce is one of our favorites for good reason. Our slimmed-down version of this Italian classic relies on chicken broth—and just a touch of olive oil—for texture. And yes, taking the extra step of toasting the pine nuts really brings out their flavor and nicely complements all of the fresh basil, Parmesan cheese, and garlic. Otherwise, all you have to do is throw all the ingredients in a blender or food processor and blend until the sauce comes together. We prefer long pasta for pesto, but you can use it for everything from pizza sauce to sandwiches and breakfast.
