• 1 teaspoon salt

• 1 teaspoon freshly ground black pepper

Directions

1. Caramelize the Onions: Heat olive oil over medium-low heat. Add the sliced onions and sauté until golden, about 20 minutes. Add sugar halfway to speed up caramelization. Stir in jalapeños and cook for 2-3 minutes.

2. Prepare the Smash Burgers: Divide ground beef into 4 portions. Heat olive oil in a skillet over medium-high heat, then smash the beef into thin patties. Season with salt and pepper. Cook for about 2 minutes until golden-brown, then flip and add cheese to melt.

3. Toast the Buns: Toast the buns in a skillet until golden and slightly crispy, about 2 minutes.

4. Assemble the Burgers: Spread mayonnaise (and mustard, if desired) on the buns. Place the burger patty on the bottom bun, top with the caramelized onions and jalapeños. Add pickled jalapeños for extra spice if desired. Place the top bun and gently press.
