Is the Krabby Patty supposed to be crab?
In the show it is generally depicted as a burger, and for this recipe we are going full classic: beef. If you want a seafood version, you can swap in a crab cake style patty, but the flavors here are built for a smash burger.
What is “secret sauce” made of?
My go-to: mayo, ketchup, mustard, sweet pickle relish, and a splash of pickle brine, plus garlic powder and paprika. It tastes like a diner sauce with better balance.
Do I have to do double patties?
No, but it is the most smash-burger-ish way to do it. Two thin patties mean more crust and a burger that actually fits the bun. This recipe is written for double patties (8 small smashes) so nothing turns into a 7-inch dinner plate situation.
Can I make these without a cast iron skillet?
Yes. Use the heaviest skillet you have, ideally stainless steel. A nonstick pan works, but keep the heat at medium-high, not nuclear, since nonstick coatings do not love extreme heat. The key is a hot pan and a firm press.
How do I know when they are done?
Smash burgers cook fast. You are looking for a deeply browned crust and no raw spots. For food safety, ground beef is considered done at 160°F. If you are not using a thermometer, cook until the center is no longer pink.
How do I keep the patty from sticking when I smash?
Two tricks: lightly oil the pan and use parchment between the spatula and meat. Also do not move the patty until it naturally releases. If it is fighting you, it is not ready yet.
