A quick and easy smash burger recipe cooked on a Blackstone griddle, featuring crispy edges, juicy centers, and sweet caramelized onions. Perfect for weeknight dinners or impromptu cravings.

Ingredients

Scale
  • 1 pound (450g) ground beef (80/20 blend)
  • 2 medium yellow onions, thinly sliced
  • Salt and pepper to taste
  • 4 slices cheese (American or cheddar, optional)
  • 4 soft burger buns (preferably brioche or potato)
  • 2 tablespoons vegetable oil or butter
  • Pickles, lettuce, tomato (optional toppings)

Instructions

  1. Heat 1 tablespoon of butter or oil on the griddle over medium heat. Add the thinly sliced onions and a pinch of salt. Stir occasionally, letting them soften and slowly brown until deep golden and sweet, about 15-20 minutes. Lower heat if onions start burning.
  2. In a mixing bowl, gently combine the ground beef with salt and pepper. Avoid overmixing. Divide into four equal portions and loosely shape into balls.
  3. Increase the griddle heat to medium-high. Add a drizzle of oil to prevent sticking. The surface should be hot enough to make the beef sizzle instantly.
  4. Place each ball on the griddle and press down firmly with a spatula or burger press until the patty is about 1/4-inch (0.6 cm) thick. Hold for about 10 seconds to set the shape.
  5. Cook the patties undisturbed for 2-3 minutes per side until edges are crispy and brown. Flip carefully. If using cheese, add a slice immediately after flipping to melt.
  6. While burgers cook, spread butter on the cut sides of the buns and toast them face down on a cooler spot of the griddle for 1-2 minutes until golden and crispy.
  7. Assemble the burgers by placing patties on toasted buns, topping generously with caramelized onions and optional toppings like pickles or lettuce.
  8. Serve immediately while hot and crispy.

Notes

Keep the griddle hot to prevent sticking and achieve a crispy crust. Pat beef dry before seasoning. Do not press patties after the initial smash to retain juices. Caramelize onions low and slow for best flavor. Cheese is optional. For gluten-free, use gluten-free buns or lettuce wraps.
