Ingredients may vary by restaurant and homemade recipe, but queso blanco dip always starts with white American cheese, some sort of milk or cream, and jalapenos. Our recipe also includes Monterey Jack cheese because it melts down so nicely and has a bolder flavor than American. Grated onion adds flavor and a little texture, and cilantro brings the Mexican flair. Finally, a dollop of fresh pico in the center brightens the whole dish!
