Bring the steak to room temperature.
Remove the flank steak from the refrigerator 30 minutes before cooking. Pat it completely dry with paper towels. This ensures a deep, even sear.
TIPDon't skip the resting period — pulling a cold steak from the fridge contracts the muscle fibers and leads to uneven cooking. - prep · ~5 min
Make the chimichurri sauce.
1.In a mixing bowl, combine finely chopped parsley, fresh oregano, minced garlic, red wine vinegar, olive oil, red chili flakes, and a pinch of salt.2.Whisk vigorously until the oil and vinegar emulsify slightly.3.Let the chimichurri rest at room temperature for at least 15 minutes to meld the flavors. - grill · ~3 min
Season and preheat the grill.
1.Preheat a cast-iron grill pan or outdoor grill over high heat until smoking hot.2.Brush both sides of the steak lightly with olive oil.3.Season generously with a pinch of salt and freshly cracked black pepper right before it hits the heat.TIPHigh heat is non-negotiable. You need to hear an immediate sizzle when the meat touches the metal to form a crust. - grill · ~10 min
Grill the flank steak to medium-rare.
1.Place the steak on the hot grill at a 45-degree angle.2.Sear undisturbed for 4-5 minutes until a deep brown crust forms.3.Flip and cook the second side for another 4-5 minutes.4.Check with a meat thermometer—medium-rare registers 130-135°F (54-57°C).TIPFlank steak is lean and thin. Avoid the temptation to move it around; letting it sit still is the secret to that charred, crusty exterior. - rest · ~10 min
Rest the meat.
Transfer the steak to a cutting board and tent loosely with foil. Rest for exactly 10 minutes. This lets the juices redistribute so they don't spill out when you slice.
TIPCutting into a steak immediately is the quickest way to lose all its moisture. Patience here is key. - prep · ~2 min
Slice against the grain.
Look for the long parallel muscle fibers running through the steak. Cut thin slices perpendicular to those fibers, holding your knife at a slight angle. This shortens the tough fibers and makes every bite tender.
TIPSlice thinly (about 1/4 inch) and against the grain only—this is non-negotiable with flank steak. - assemble · ~1 min
Plate and drizzle with chimichurri.
Fan the sliced steak on a warm platter. Spoon the fresh chimichurri generously over the top, letting it run into the crevices. Serve immediately with any remaining sauce on the side.
What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Pat the steak completely dry before searing to ensure a deep, crusty brown exterior.
- 2Let the chimichurri rest for at least 15 minutes so the garlic and herbs meld together.
- 3Use a high-smoke-point oil like avocado oil if grilling on extremely high heat.
- 4Always slice flank steak against the grain at a 45-degree angle for maximum tenderness.
- 5Rest the steak for a full 10 minutes to keep juices from spilling onto the cutting board.

Adapt it for your goals.
Cilantro-lime chimichurri
Swap half the parsley for fresh cilantro and replace the red wine vinegar with lime juice. This gives the sauce a brighter, more citrusy kick that pairs well with grilled chicken or fish.
smoky chipotle steakSmoky chipotle steak
Add 1-2 minced chipotle peppers in adobo to the chimichurri for a smoky, spicy depth. Great for those who love a bolder, Southwestern-style heat.
low oil versionLow-oil version
Reduce the olive oil in the chimichurri to 2 tablespoons and add 2 tablespoons of water or vegetable broth to loosen the sauce. This cuts calories while keeping the herb flavor intact.
