These juicy Hawaiian smash burgers are sure to be a hit at your next barbecue. They are quick and easy to make on a flattop grill or even a pan on the stove.
Cut out 8 squares of parchment paper (about 4x4-inches) and set aside. Prepare the optional toppings, as desired.
Heat a large flat-top grill pan or large cast iron pan to medium heat. When hot, brush lightly with canola (or other neutral flavored oil).
Prepare hamburger buns by buttering each side and toasting on the grill or flat top/cast iron pan. Set aside and keep warm (either on warming rack on grill or at 170 degrees F the oven).
Slice and prepare pineapple. Place on grill or flat top/cast iron pan and and cook for 4-5 minutes, flipping once.
Divide the beef into eight 4-ounce portions and roughly shape into round forms (it's actually better if you don't try to get them too perfect).
Place one 4-ounce beef portion at a time on the pan with the parchment square on top. Using a sturdy large spatula, immediately smash patty by pressing down with your hand on the spatula until patty is about ⅓-inch thick.
Remove parchment and sprinkle desired seasoning on top, to taste. Repeat with remaining burgers. Let cook until golden browned on bottom and edges, about 2 to 3 minutes. Flip burgers, season remaining side, and immediately top with cheese. Cook for an addition 1 minute or so.
Spread bbq sauce on prepared buns. Then place cooked burgers, grilled pineapple and desired toppings on top. Serve immediately.
Ground beef: I use 80-85% lean ground beef for burgers. The higher fat content makes for a juicy burger. You can go with leaner ground beef, but keep in mind it won't be as juicy in this recipe.
Burger or steak seasoning: If you want simple, coarse sea salt + freshly ground black pepper is perfect. We also sometimes use smoked Himalayan salt or Penzy's 4/s spicy special season salt. Some more favorites include Northwoods fire (from Penzeys), Chicago Steak (from Penzeys), or Spade L beef seasoning (from Amazon, aff. link)
Pineapple: I have only used fresh pineapple; you could experiment with canned. Pat dry and watch carefully on the grill (more fragile than fresh pineapple).
BBQ sauce: Sweet baby Ray's or KC Masterpiece are our favorite store bought varieties. But the best is this Homemade Barbecue Sauce.
Variations: You can make the portions slightly smaller if you like (like a slider size, just keep an eye on the cooking time). Thicker patties don't work well using this method, but you can stack two patties with cheese in the middle for a double stack!
