5-Minute Pan-Seared Flank Steak For Two (or a Crowd)

How to Pan-Sear Flank Steak Like a Pro (No Restaurant Required)

Beef is a favorite in our house, though we eat it less often these days. When we do, it comes from Bruno, our local butcher in Northern Italy who sources everything sustainably from Italian farmers. The meat tastes like meat should, and supporting Bruno feels right.

Because we eat it less, the cooking has to be right, especially for the pricier cuts. Below are the tips I rely on for a proper sear at home.

Use a heavy-bottomed skillet

Cast iron, carbon steel, or 7-ply stainless (like All-Clad) hold heat evenly and give you that even, golden crust. Thin, lightweight pans create hot spots and inconsistent browning.

Dry the steak completely

Wet steak steams instead of sears. You'll end up with grey meat and no crust. Pat dry with paper towels right before seasoning. For ribeye, strip, filet, or T-bone, take it further: rest the steak uncovered on a plate in the fridge overnight to dry the surface even more.

Salt generously, but only at the last minute

Good beef needs salt and freshly cracked black pepper. That's it (use Lawry's or Montreal seasoning if that's your thing-your steak, your call). I use Diamond Crystal kosher salt because the larger crystals make it easy to see how much I've used.

Salt the steaks just before they hit the pan. Salting earlier draws moisture to the surface and you're back to a wet steak. If it ends up under-seasoned, finish with a pinch of Maldon flake salt for a little crunch.

Use a high-smoke-point oil (not olive oil)

Vegetable, grapeseed, or another neutral oil with a smoke point of 400-450°F (204-232°C) is what you want. Skip the extra-virgin olive oil here. EVOO smokes around 350°F (176°C), which means it burns before the steak sears, fills your kitchen with smoke, and loses the antioxidants that make it worth using in the first place. Save it for finishing.

Get the pan screaming hot

Wait for the oil to just start smoking, then add the steaks. The contact should sound like applause-a sharp, sustained sizzle. If it's a quiet hiss, the pan isn't ready and you've already lost your crust.

Don't move the steak (mostly)

For thinner cuts (flank, skirt, hanger, iron): place them down and leave them alone. Constant pan contact is what builds the crust. After about 2 minutes, lift one corner with tongs to check the underside. Flank and skirt sometimes curl in the middle-press down with a spatula or weight to keep the center in contact with the pan.

For thick bone-in cuts (ribeye, porterhouse, T-bone, bistecca alla Fiorentina): periodic flipping actually helps these cook evenly and develop a uniform crust. Flip every 1-2 minutes once you're past the initial sear.

Add butter and aromatics late

Butter, garlic, rosemary, and thyme will burn if added too early. Wait until you've flipped the steak (roughly halfway through cooking), then drop them in and baste constantly, tilting the pan and spooning the foaming butter over the top.

Skip butter for thinner cuts-they don't need it. Or add a pat of compound butter on top while the steak rests off the heat. That works beautifully too.

Use a timer (and a thermometer if you want one)

A timer takes the guesswork out of when to flip and when to pull the steak. It's not foolproof-thickness, bone-in vs. boneless, your stove, your skillet all change the math-but it's a useful anchor while you're prepping sides.

I don't usually reach for a thermometer when pan-searing, but plenty of cooks rely on one and that's smart, especially for dinner parties or expensive cuts. Practice teaches you the most. A good instant-read thermometer just speeds up the learning curve.

Flank Steak vs. Skirt Steak: Which Should You Use?

Both cuts come from the underside of the cow, both are lean and fibrous, and both reward a hard sear or a good marinade. They're the workhorses behind carne asada, fajitas, tacos, and stir-fries. But they aren't interchangeable, and knowing the difference will help you pick the right one.

	Flank Steak	Skirt Steak
Where it's from	Lean belly muscle near the hind legs	Diaphragm muscle between chest and abdomen
Look	Thinner, slightly shorter, grain runs straight	Thicker (up to 2x), slightly longer, grain runs diagonal
Fat & flavor	Very lean, intense beefy flavor	More marbling, richer flavor (fat = flavor)
Texture	Lean and slightly chewy, holds shape when cooked	Slightly chewy, shrinks a bit more as fat renders
Best for	Stir-fry, roulade, bibimbap, grilled steak	Fajitas, carne asada, braising

Flank Steak

Flank is the leaner of the two, with no real marbling and a straight, parallel grain. It's intensely beefy and holds its shape because there's not much fat to render off. It rewards a quick, hot cook (pan-sear or grill) to medium-rare, then a hard rest before slicing thin across the grain-that's non-negotiable, or you'll end up chewing the same bite for ten minutes.

A few hours in a marinade does double duty: adds flavor and breaks down the muscle fibers. This is one of my go-to "steak fix" cuts when I don't want to spend ribeye money.

Skirt Steak

Skirt comes from the diaphragm-a hardworking muscle that delivers more fat and a bigger flavor payoff. The grain runs on a diagonal, the cut is thicker, and it shrinks a little more than flank as the fat renders. Same rules apply: hot pan or hot grill, cook quickly to rare or medium, slice thin across the grain.

Skirt is the classic fajita cut, and it's what you'll find in the best carne asada. It also takes beautifully to a long, slow braise if you'd rather go that route-several hours of low heat breaks the fibers down completely and turns it tender.

Which one should you buy?

If you want a leaner, beefier steak to slice and serve, go flank. If you want richer flavor and you're making fajitas, tacos, or carne asada, go skirt. Either way, marinate, sear hard, slice thin across the grain.
