Can you make the pickle sauce ahead of time?
Yes, mix the mayonnaise, ketchup, and mustard up to 2 days in advance and store in the refrigerator. Add to the chips just before serving to keep them crispy.
How do you caramelize onions for this recipe?
Cook diced onions in butter over medium-low heat for 10–15 minutes, stirring occasionally, until golden brown and soft. This builds the sweet, rich flavor that defines the dish.
Can you substitute the American cheese?
Yes; cheddar, Monterey Jack, or provolone work well. American cheese melts smoothly, so other cheeses may require extra heat to fully melt.
What chips work best if you don't have kettle-cooked?
Use thick-cut or ridge-cut chips for durability. Thin chips will break under the weight of the toppings and won't hold up as well when eaten from the bag.
How long does this stay crispy after assembly?
Assemble and serve within 5–10 minutes. The chips will soften as they absorb moisture from the meat and sauce.
