how to cook flank steak

To cook flank steak so it’s tender, juicy, and flavorful, you mainly need three things: a good marinade or seasoning, very hot and fast cooking, and slicing against the grain when serving.

Quick Scoop (What You Actually Do)

Marinate or season the steak.
Let it come closer to room temperature.
Cook it hot and fast (grill, pan, or broiler).
Rest it.
Slice thinly against the grain.

Step-by-step: Basic Method

1. Prep and season

Pat the flank steak dry with paper towels for better browning.

Rub lightly with oil, then season generously with salt and pepper (you can add garlic powder, paprika, or a steak rub if you like).

Let it sit at room temperature for about 20–30 minutes so it cooks more evenly.

2. Optional: Marinade for extra flavor

Flank steak loves marinades because it’s lean and a bit tough. A classic flavor combo (approximate, adjust to taste):

Soy sauce (salt + umami)
Acid: lime juice, vinegar, or cooking sherry
A little brown sugar or honey
Garlic and ginger
A bit of oil

Basic approach:

Score lightly (shallow diagonal cuts) across the surface to help the marinade penetrate.

Put steak and marinade in a zip bag, press out air, and refrigerate for at least 30 minutes and up to overnight (3–8 hours is a nice sweet spot).

Take it out of the fridge 30 minutes before cooking and pat it dry so it will sear properly.

How to Cook: Grill, Pan, or Broiler

A. Grilled flank steak

Preheat grill for direct high heat (medium-high to high) and oil the grates lightly.

Place steak on the hot grill. Cook about 4–6 minutes per side depending on thickness for medium-rare to medium.

For doneness, use a meat thermometer: about 120°F for rare, 130°F for medium-rare, 135°F for medium.

Pull the meat off the grill about 5°F before your target; it will rise a bit as it rests.

B. Pan-seared flank steak (stovetop)

Heat a heavy skillet (cast iron is ideal) over medium-high until very hot.

Add a thin film of high-heat oil.
Lay the steak in the pan and leave it alone for 3–4 minutes to get a good sear.

Flip and cook another 3–4 minutes, checking temperature toward the end for your preferred doneness (again, around 130°F for medium-rare).

If your steak is thick, you can lower the heat a bit after searing or finish it in a 375°F oven for a few minutes.

C. Broiled flank steak (in the oven)

Position oven rack so the steak will be a few inches under the broiler.
Preheat broiler on high and line a sheet pan with foil.
Place steak on the pan and broil about 5 minutes per side for medium-rare, adjusting for thickness and checking internal temperature (aim ~130°F for medium-rare).

Rest before slicing.

Resting and Slicing (The Tenderness Secret)

Flank steak can taste tough if you skip this part.

Rest the cooked steak on a cutting board for at least 5–10 minutes so juices redistribute.
Look at the lines of the meat fibers (the “grain”)—on flank steak they usually run lengthwise.

Turn the steak so you slice across those lines, not along them.
Slice thin (about 0.5–1 cm thick) at a slight angle. This shortens the fibers and makes each bite much more tender.

Simple Serving Ideas

Classic plate: Sliced steak with roasted potatoes and a green vegetable.
Fajitas/tacos: Slice, toss with lime and cilantro, serve in tortillas with onions and peppers.
Steak salad: Chilled slices over greens with a vinaigrette.
With sauce: Chimichurri or a chili-herb butter on top is very popular and gives a fresh, bright contrast.

HTML Table: Doneness & Times

Here’s a quick reference you can glance at while cooking (always trust your thermometer over time, since steaks vary):

[5][1] [5][1] [7][5][1] [3][5] [3][1] [3] [3] [3]

Doneness	Internal Temp (°F)	Approx. Time per Side*	Notes
Rare	120–125°F	3–4 minutes	Very red center, very soft.
Medium-rare	130°F	4–5 minutes	Best balance of tenderness and juiciness.
Medium	135–140°F	5–6 minutes	Pink center, slightly firmer but still good.
Well done	150°F+ (not recommended for flank)	6–7+ minutes	Can get dry and chewy.

*Times assume a grill or pan over medium-high heat for an average-thickness flank steak; always confirm with a thermometer.

Little Story-style Tip

Imagine you’re cooking for a group where one friend loves very pink steak and another swears they only eat it well done. A nice trick with flank steak is that the ends naturally cook more, while the center stays closer to medium- rare.

When you slice it, you’ll see some pieces more done and some less—almost like a built-in tasting flight—so everyone can grab what they like.
