Step-by-Step Instructions

Here’s how to make Jalapeño-Onion Smash Burgers:

Prepare the Ingredients:

1. Chop the Jalapeños and Onions: Finely dice the jalapeños and onions so they blend seamlessly into the burger patties.
2. Form the Beef Balls: Divide the ground beef into four equal portions and roll them into loose balls. Avoid packing the meat too tightly to keep the burgers tender.

Cook the Smash Burgers:

3. Heat the Cooking Surface: Heat a large cast-iron skillet or griddle over medium-high heat. Add vegetable oil and let it shimmer.
4. Smash the Patties: Place a beef ball onto the hot skillet. Immediately top with a spoonful of chopped jalapeños and onions. Using a heavy spatula or burger press, firmly smash the patty down until it’s about ¼-inch thick. Repeat with the remaining patties.
5. Season and Sear: Sprinkle salt, black pepper, and garlic powder over each patty. Let them cook undisturbed for about 2-3 minutes until the edges are crispy and deeply browned.
6. Flip and Add Cheese: Flip each patty and immediately place a slice of cheese on top. Cook for another 1-2 minutes until the cheese melts and the burger is cooked through.

Toast the Buns and Assemble:

7. Toast the Buns: While the burgers cook, melt butter in a separate pan and toast the buns until golden brown.
8. Assemble the Burgers: Place each patty on a toasted bun. Add your favorite toppings, such as lettuce, tomato, pickled jalapeños, or spicy mayo.
9. Serve Immediately: Serve hot with fries, onion rings, or a side of coleslaw.

• With a Side Salad: A simple side salad with a tangy vinaigrette complements the richness of the burger.
• With a Spicy Kick: Add extra jalapeños or a drizzle of hot sauce for an even bolder flavor.
