Smash Burger
These ultra-crispy smash burgers deliver restaurant-quality results at home in under 20 minutes. By pressing seasoned ground beef balls onto a scorching hot griddle, you create irresistible caramelized edges through the Maillard reaction — turning simple 80/20 ground beef into something extraordinary with juicy centers and deeply browned, crispy crusts.
Equipment
- Cast iron skillet or griddle Heavy-bottomed for even heat retention
- Metal spatula Sturdy and flat for smashing patties
- Parchment paper Makes smashing easier and cleaner
- Kitchen scale (optional) For consistent 4-oz portions
- Tongs For handling hot patties safely
Ingredients
For the Patties
- 1.5 lbs ground beef 680g, 80/20 blend recommended
- coarse kosher salt or sea salt to taste, applied generously
- black pepper freshly ground, to taste
For Assembling
- 4 hamburger buns brioche or potato buns work great
- 4 slices American cheese deli-style for best melt
Toppings (as desired)
- lettuce
- tomato sliced
- onion sliced
- pickles
- special sauce or condiments mayo, mustard, or burger sauce
Instructions
- Divide ground beef into 4-ounce portions and loosely roll each into a ball, handling the meat as little as possible. Season generously with salt and pepper on all sides, then let rest at room temperature for 10–15 minutes.
- Place your cast iron skillet or griddle over high heat and preheat for at least 5 minutes until smoking hot — a drop of water should instantly sizzle and evaporate. Do not add oil; the beef's natural fat is sufficient.
- Place a beef ball on the hot surface, cover with a sheet of parchment paper, and press down firmly with a sturdy spatula for 3–5 seconds to smash the patty as thin as possible (about ¼ inch). Remove the parchment paper.
- Cook the patty undisturbed for 2–3 minutes until the edges are deeply browned and crispy and the patty releases naturally from the pan. Do not move or press it again during this time.
- Slide your spatula under the patty and flip in one smooth motion, then immediately place a slice of American cheese on top. Cook for 1–2 minutes until the cheese is fully melted.
- While burgers finish cooking, place buns cut-side down on the griddle and toast for 30–60 seconds until golden brown, taking advantage of the residual beef fat on the surface. Watch carefully to avoid burning.
- Spread sauce on the bottom bun, layer cold toppings, then place the hot cheesy patty on top and finish with remaining toppings and the top bun. Serve immediately.
Notes
- Use high heat: The cooking surface must be smoking hot before adding beef — this is the key to crispy edges.
- Don't overwork the meat: Handle ground beef minimally when forming balls; overworking creates tough, dense patties.
- Smash only once: You get one opportunity to press for maximum surface contact — do not re-smash after the initial press.
- 80/20 is non-negotiable: Leaner beef will result in dry, less flavorful patties; the fat is essential for thin smash burgers.
- Time your flip: Wait until edges are deeply browned and the patty releases on its own before flipping.
- Double smash burger: Stack two thin patties for an extra indulgent double burger.
- Oklahoma style: Press thin-sliced onions into the ball before smashing for a caramelized onion-infused patty.
- Storage: Refrigerate cooked patties in an airtight container for up to 3 days, or freeze individually wrapped for up to 2 months.
- Reheating: Reheat patties in a hot skillet for 1–2 minutes per side; avoid the microwave as it makes the crispy edges soggy.
- Make-ahead tip: Portion burger balls up to 4 hours ahead and refrigerate; season just before cooking to prevent salt from drawing out moisture.
