Ingredients:
Burger Sauce:
- 3 tablespoons mayonnaise
- 1.5 tablespoons ketchup
- 1 teaspoon Worcestershire sauce
- ½ teaspoon black pepper
- ¼ teaspoon garlic powder
- ¼ teaspoon kosher salt
Burger Patties:
- 1.5 pounds lean ground beef
- 1 teaspoon canola oil
- 1 large yellow onion, thinly sliced
- 1 large jalapeño chile, thinly sliced
- 1 ¼ teaspoons kosher salt, divided
- ¾ teaspoon black pepper, divided
- 4 slices American cheese
- 4 soft hamburger buns, split and toasted
Instructions:
1. Prepare the Burger Sauce:
In a small bowl, mix together mayonnaise, ketchup, Worcestershire sauce, black pepper, garlic powder, and kosher salt. Stir well, cover, and refrigerate until ready to use.
2. Caramelize the Onions and Jalapeños:
Heat a large cast-iron skillet over medium heat and add the canola oil. Add the sliced onions and jalapeños to the skillet, seasoning with ¼ teaspoon kosher salt and ¼ teaspoon black pepper. Cook, stirring occasionally, until the onions are caramelized and the jalapeños are softened, about 10-15 minutes. Transfer to a bowl and set aside.
3. Form the Burger Patties:
Divide the ground beef into 8 equal portions (approximately 3 ounces each). Gently form each portion into a loose ball, avoiding overworking the meat to maintain tenderness. Place the balls on a parchment-lined baking sheet and refrigerate until ready to cook.
4. Cook the Smash Burgers:
Wipe the skillet clean and return it to high heat until it begins to smoke slightly. Place a few beef balls into the hot skillet, ensuring not to overcrowd. Using a sturdy spatula or a burger press, firmly press down each ball to flatten it into a thin patty. Season the patties with a pinch of the remaining kosher salt and black pepper. Cook until the edges are crispy and the center is cooked through, about 2-3 minutes per side. During the last minute of cooking, place a slice of American cheese on each patty to melt.
5. Assemble the Burgers:
Spread a generous amount of the prepared burger sauce on the cut sides of the toasted hamburger buns. Place a cheese-topped patty on the bottom bun. Top with a spoonful of the caramelized onion and jalapeño mixture. Add any additional desired toppings, such as lettuce, tomato, or pickles. Cover with the top bun and serve immediately.
Serving Suggestions:
Pair these Jalapeño-Onion Smash Burgers with crispy fries, onion rings, or a fresh side salad. For an extra kick, serve with a spicy dipping sauce or jalapeño-infused aioli.
