Ingredients

You don’t need fancy stuff — just these basics!

3 tablespoons mayonnaise
1 1/2 tablespoons ketchup
1 teaspoon Worcestershire sauce
1/2 teaspoon black pepper
1/4 teaspoon garlic powder
1/4 teaspoon kosher salt
1 1/2 pounds high-quality 80% lean ground beef
1 teaspoon canola oil
1 large yellow onion, very thinly sliced (about 2 cups)
1 large jalapeño chile, very thinly sliced (about 1/2 cup)
1 1/4 teaspoons kosher salt, divided
3/4 teaspoon black pepper, divided
4 American cheese slices
4 soft hamburger buns, split and toasted

Directions

Make the Burger Sauce: Stir together mayonnaise, ketchup, Worcestershire sauce, 1/2 teaspoon black pepper, garlic powder, and 1/4 teaspoon kosher salt in a small bowl. Cover and chill until ready to use.
Prep the Patties: Divide the beef into 8 (3-ounce) portions, shape each into a loose ball, and chill on a plate.
Get the Grill Ready: Cut a 3-inch square of parchment paper and set aside. Preheat your grill to high (450°F to 500°F) and place a large cast-iron skillet or griddle on to preheat.
Cook the Onions and Jalapeños: Drizzle the skillet with oil. In batches if needed, arrange onion slices into 8 mounds on the skillet, top with jalapeño slices, and sprinkle with 1/2 teaspoon salt and 1/4 teaspoon pepper. Cook, undisturbed, until the onions brown, about 30 seconds to 1 minute.
Smash Those Patties: Place a beef ball on each onion mound. Top with the parchment square and press firmly to flatten into a 4-inch-wide patty. Sprinkle with the remaining salt and pepper and cook without moving for 2–3 minutes.
Flip and Cheese It Up: Flip the patties so the onion-jalapeño side is up. Top with a slice of cheese on 4 patties. Continue cooking until browned and melted, about 1 minute and 30 seconds to 2 minutes.
Assemble Your Burgers: Top each cheesy patty with a plain patty to create double stacks. Place on the bottom buns and spread about 1 tablespoon of burger sauce on each top bun. Place on top and serve immediately!
