Argentine Smash Burger with Chimichurri and Crispy Provolone Step-by-step instructions

Before you start

Set everything out before the pan goes on the heat, because the cooking itself is fast. Roll the beef into two loose 4-ounce balls and leave them at room temperature for no more than thirty minutes while the equipment heats — any longer and they belong back in the refrigerator.

Cut the provolone into two thick rounds and pat the surfaces dry so the cheese crisps instead of steams. Chop the chimichurri ingredients and stir the sauce together, then split the roll. Once the griddle is hot, nothing stops again until the burger is built.

Instructions

Make the chimichurri

1. 1Chop the chimichurri base
   On a cutting board, finely chop the flat-leaf parsley, the garlic cloves, and the red chili, removing the seeds first if a milder sauce is preferred. Aim for a fine, even mince so every spoonful of chimichurri distributes flavor evenly rather than delivering bites of raw garlic. Scrape everything into a small mixing bowl as you go.
   Look for The parsley should be chopped fine enough to spoon, with no large stem pieces left behind.
   Tip A sharp chef's knife matters more than speed here; a dull blade bruises the parsley and turns it dark.
2. 2Stir the sauce together
   Stir the red wine vinegar into the chopped herbs, then pour in the extra-virgin olive oil and mix until the sauce looks glossy and emerald green. Let the chimichurri sit at room temperature while the griddle heats and the burgers cook, so the garlic mellows and the flavors marry.
   Look for The sauce should look vibrant green with a thin layer of oil rising to the surface.
   Tip If the sauce tastes sharp, let it rest a few extra minutes; the vinegar rounds as the garlic macerates.

The chimichurri should look intensely green and slightly glossy, with a thin film of oil on top and no large garlic chunks. Taste it on the tip of a spoon: it should be balanced enough to season a whole burger, with a clear vinegar snap and a slow chili warmth at the back of the throat. If it tastes flat, a few more minutes of maceration will mellow the garlic and round the vinegar. Set the bowl near the stove — the sauce only improves as the beef cooks, and it goes on at the very last second.

Smash the beef, crisp the cheese

3. 3Preheat the griddle hard
   Set a cast-iron griddle or heavy skillet over medium-high heat for a full five minutes, until a drop of water skitters and evaporates on contact. The target is around 470°F (243°C); without a thermometer, judge by a faint shimmer across the surface and the first light wisp of smoke. Do not add oil — the beef brings its own fat.
   Look for Water droplets should dance and vanish within a second rather than sitting and steaming.
   Tip Start heating the pan before chopping anything else; cast iron needs the longest head start of the whole recipe.
4. 4Smash and sear the patties
   Divide the ground beef into two loose 4-ounce balls and place them on the hot griddle. Press each one flat with a sturdy spatula to about 4 1/2 inches wide, then cook undisturbed for 90 seconds until the edges are deep brown and lacy. Flip, and cook about 1 minute more, until the interior reaches 160°F (71°C).
   Look for Listen for an aggressive sizzle the moment the beef hits the steel; silence means the griddle is not hot enough.
   Safe temperature 160°F (71°C) internal temperature (ground meat)
   Tip Press firmly for three seconds, once. Repeated pressing squeezes out the juices that keep the patties moist.
5. 5Crisp the provolone on the steel
   Slide the patties to a cooler edge of the griddle and set the provolone rounds directly on the hot steel in the open space. Let them fry undisturbed for 60 to 90 seconds, until the undersides are deeply golden and crusted, then lift them off with a thin spatula while they are still pliable enough to drape over the beef.
   Look for Look for a lacy, browned rim and bubbling centers; the cheese should lift in one clean piece.
   Tip Aged provolone crisps like frico; press the round lightly with the spatula to help it crust evenly.

The patties should have deep-brown, lacy edges and a crust that releases cleanly from the pan, and the thickest part of the beef should register at least 160°F (71°C) on an instant-read thermometer. The provolone rounds should be golden underneath with a crackling rim, lifting off the steel in one piece.

The kitchen should smell strongly of seared beef and toasted cheese at this point. If the cheese browns before the beef finishes, slide it onto a plate and continue — the crust is the goal, not the exact timing on the clock.

Toast, stack, and drench

6. 6Toast the roll on the griddle
   Split the crusty roll and set it cut-side down on the griddle for 30 to 45 seconds, just long enough to pick up color and a little rendered beef fat. A toasted interior stands up to the chimichurri without turning soggy, so do not rush this step or skip it entirely, even when the griddle looks crowded.
   Look for The cut sides should be golden with a few dark spots, not charred black.
   Tip If the griddle is crowded, toast the roll first, before the beef goes down, and hold it warm on a plate.
7. 7Stack patties and provolone
   Set the two smash patties on the bottom half of the roll, overlapping slightly, then lay the crispy provolone rounds on top so they drape over the beef. The residual heat softens the cheese just enough to hug the patties while the crusty edges stay snappy, which is exactly the contrast this burger is built on.
   Look for The provolone should sit flat and crackle faintly when pressed lightly with the spoon.
   Tip Work quickly while everything is hot; the contrast of crisp cheese and juicy beef fades within minutes.
8. 8Drench in chimichurri and serve
   Spoon the chimichurri generously over the provolone and patties, letting it run down the sides, then cap with the top of the roll. Serve immediately, with any extra sauce in a small bowl alongside for dipping. Bite in while the cheese is still crackling and the herb sauce is at its brightest and greenest.
   Look for The sauce should pool slightly at the edges of the patty, not flood the crumb of the roll.
   Tip Save a final spoonful of chimichurri to refresh the flavor if the burger sits for a minute or two.

The finished burger should sit tall and glossy, chimichurri running down the sides of the patties and pooling lightly on the plate. The roll's cut surfaces should be golden and dry to the touch, never steamed soft. Press the top gently: the provolone should crackle, and the beef should feel springy rather than hard. Serve at once — within a minute or two the cheese loses its snap and the sauce soaks into the crumb, and while that is still delicious, the first-minute texture is what this recipe is built entirely around.

Common mistakes

The most common failure is a crowded, cool griddle: beef placed before the pan is fully hot steams instead of searing and never develops lacy edges. The second is overworking the meat — compact balls and repeated pressing turn smash burgers into dense pucks.

Third, thin provolone: sandwich slices melt and slide off instead of crisping, so insist on a thick cut. Finally, salting the beef before it hits the pan draws moisture to the surface and slows browning; season the patties only after they are already on the steel, crust-side down.

How to tell it’s done

Ground beef is safely cooked at an internal temperature of 160°F (71°C), and with smash-thin patties that point arrives quickly, so start checking around the seventy-five-second mark after flipping. Visually, the patties should show deep-brown, lacy edges, a firm springy top, and no translucent raw patches in the center.

The provolone is done by color, not temperature: a golden, crackling underside and a lacy rim. The roll is ready when its cut faces are dry and golden. Everything goes onto the roll hot, in seconds, because the first-minute texture is the whole point of the recipe.
