# What You Need:

→ Smashburger Patties

01 - 1 pound ground beef (80/20 blend)
02 - 1 teaspoon kosher salt
03 - 0.5 teaspoon freshly ground black pepper
04 - 1 teaspoon garlic powder

→ Quesadillas

05 - 4 large flour tortillas (8-10 inches each)
06 - 8 slices sharp cheddar cheese
07 - 4 slices American cheese
08 - 1 small yellow onion, thinly sliced
09 - 2 tablespoons vegetable oil, divided
10 - 2 tablespoons unsalted butter, melted

→ Sauce

11 - 2 tablespoons mayonnaise
12 - 1 tablespoon Dijon mustard
13 - 1 teaspoon Worcestershire sauce

→ Optional Garnishes

14 - Sliced pickles
15 - Chopped fresh cilantro
16 - Salsa
17 - Sour cream

# How To Make:

01 - In a medium bowl, gently combine ground beef with salt, pepper, and garlic powder until just incorporated, taking care not to overwork the meat.
02 - Preheat a flat griddle or heavy skillet over medium-high heat. Add 1 tablespoon vegetable oil and spread to coat the surface evenly.
03 - Place sliced onion on one side of the griddle and cook, stirring occasionally, until golden and softened, approximately 5 minutes. Transfer to a plate.
04 - Divide beef mixture into 8 equal portions and roll each into a loose ball. Place 4 balls onto the hot griddle with even spacing.
05 - Immediately press each beef ball flat using a heavy spatula or burger press to create thin patties approximately 4 inches across. Cook without disturbing until edges are deeply browned and juices bubble up, about 2 minutes.
06 - Season patty tops with salt and pepper. Flip patties, then immediately top each with 1 slice cheddar and 1 slice American cheese. Cook until cheese melts and edges crisp, about 1 minute. Transfer to a plate.
07 - Wipe griddle clean and reduce heat to medium. Brush both sides of each tortilla lightly with melted butter.
08 - Whisk together mayonnaise, Dijon mustard, and Worcestershire sauce until combined.
09 - Place a buttered tortilla on the griddle. Layer 2 cheesy patties side by side, sprinkle with cooked onions, and drizzle with prepared sauce. Top with a second buttered tortilla.
10 - Cook until bottom tortilla is golden and crisp, about 2 minutes, pressing gently with a spatula. Flip and cook opposite side until golden, about 2 minutes more.
11 - Transfer quesadilla to a cutting board and rest for 1 minute. Slice into wedges using a sharp knife or pizza cutter.
12 - Repeat assembly and cooking process with remaining ingredients to prepare 2 large quesadillas total. Serve hot with desired garnishes.

# Cooking Tips:

01 -
  • You get all the crispy-edged joy of a smashburger without needing buns or a grill.
  • The double cheese layer creates pockets of gooey, salty richness that soak into every bite.
  • It cooks fast enough for a weeknight but feels indulgent enough to impress someone.
  • Leftovers reheat beautifully in a skillet, which almost never happens with quesadillas.
02 -
  • The smash technique only works if you press hard and fast the moment the beef hits the griddle, otherwise the crust won't form properly.
  • If your tortillas are tearing when you flip, your heat is too high or you didn't butter them evenly.
  • Let the quesadilla rest for a full minute or the cheese will slide out when you cut it, trust me on this one.
03 -
  • Press the spatula down hard when you smash the beef, you want to hear it sizzle and see the edges start to brown almost immediately.
  • Brush butter on both sides of the tortilla, not just one, or you'll end up with one crispy side and one sad, floppy side.
  • If you're making multiple quesadillas back to back, wipe the griddle clean between batches so burnt bits don't stick to the tortillas.
