At its core, a slopper is a hamburger smothered in green chili sauce, topped with shredded cheese, and served open-faced on a soft hamburger bun. Often, it's accompanied by a side of French fries, which many diners prefer to pile right on top, letting the fries soak up all that chili goodness. It’s messy, it’s hearty, and it’s incredibly satisfying.

The green chili—typically a spicy, pork-laden stew made with roasted Pueblo green chilies—is what sets the slopper apart. This sauce is ladled generously over the burger, turning it into a fork-and-knife affair. Some versions include onions and additional toppings, but the basic elements remain consistent: burger, bun, green chili, and cheese.
