Flank Steak Medium Temp | Juicy Slices Every Time

Medium flank steak finishes at 140°F to 145°F, with a warm pink center and a firmer bite than medium-rare.

Flank steak rewards precision. This cut is lean, loose-grained, and thin enough to race past the sweet spot before you know it. If you want medium, the target after resting is 140°F to 145°F. Pull it from the heat at 135°F to 140°F, then let carryover heat finish the job.

That pull window matters because flank steak has less fat to cushion overcooking. Leave it on too long and the bite gets dry and stringy. Hit the temp, rest it, then slice thin across the grain and you get a steak that still feels juicy, beefy, and easy to chew.

What Medium Feels Like On The Plate

Medium flank steak should have a pink center, not a red one. The outside should be browned with a good crust, while the middle stays warm and lightly springy. When you press a slice with the tip of a fork, it should give a little, not fight back.

For this cut, medium sits near the upper edge of the pleasant zone. Ribeye can stay forgiving because fat keeps basting the meat as it cooks. Flank steak does not have that buffer. A few extra degrees can change it from juicy to chewy in one short stretch.

If you already know you like a softer bite, medium-rare is often the safer stop. If you want less red in the center, medium works well, but only when the steak is pulled on time and sliced the right way.

Flank Steak Medium Temp And Pull Temperature

The number you pull at is not the same as the number you serve at. Once the steak leaves the grill or skillet, the heat parked near the surface keeps moving inward. That rise is called carryover cooking, and flank steak usually climbs around 5°F while it rests.

Pull Temp Vs Final Temp

If your goal is medium, start checking early. Pull at 135°F to 140°F. After a 5 to 10 minute rest, the steak should settle in the 140°F to 145°F range. Wait until it reaches 145°F on the grate, and you may end up closer to medium-well by the time the knife comes out.

That’s also why a timer alone can mislead you. A thinner flank steak, a hotter grill, or a steak that came closer to room temperature can all shave minutes off the cook.

Where To Place The Thermometer

Slide an instant-read thermometer into the thickest part from the side. That angle gives a cleaner read in a flat cut. Try not to touch the grill grate, the skillet, or a thick seam of fat, since that can throw the number off.

Thickness Changes The Window

A thin supermarket flank steak can move through the medium range in a flash. A thicker butcher-cut piece gives you a little more room. That is why two steaks with the same weight can cook at different speeds.

If the steak is under 3/4 inch thick, pull closer to 135°F. If it is near 1 inch or a bit more, 138°F to 140°F is a better bet for a true medium finish. The thicker the cut, the more carryover heat you usually get.

For food safety, whole cuts of beef are handled a little differently from steakhouse doneness charts. FoodSafety.gov’s safe minimum temperature chart says steaks, roasts, and chops should reach 145°F and then rest for 3 minutes. The FDA safe food handling chart gives the same target for steaks.

So if you want medium flank steak and also want to line up with federal safety guidance, aim for the top end of medium. Pull near 140°F, rest it, and let the steak finish at 145°F. USDA’s cooking temperature note pairs whole cuts of beef with that 3-minute rest too.

How To Hit Medium On A Grill Or Pan

Start with a dry surface. Pat the steak well with paper towels before seasoning. Water slows browning, and slow browning steals time from the narrow medium window.

Then get the cooking surface properly hot before the meat goes on. Flank steak does best with hard heat at the start. You want color fast, not a slow gray climb.

On The Grill

Use direct heat first. Cook the steak until the underside browns well, then flip. On a hot grill, many flank steaks around 1 inch thick hit medium in about 8 to 12 minutes total. Flip every minute or two near the end so one side does not outrun the other.

In A Skillet Or Under A Broiler

A cast-iron skillet works much the same way. Preheat it well, add a thin film of oil, and sear fast. Under a broiler, keep the rack close enough to brown the surface without letting the center run too hot too soon. In both cases, start checking the temperature early instead of trusting the clock.

Why Resting And Slicing Matter So Much

Resting is part of the cook, not dead time. It gives the heat a chance to even out and keeps more juice in the meat instead of on the board. Five minutes is a solid floor. Ten minutes fits a thicker piece better.

Then comes the part many people rush: slicing across the grain. Flank steak has long, easy-to-see muscle fibers. Cut with those lines and every bite stays long and ropey. Cut across them and the meat feels far more tender, even at a medium temp.

What Across The Grain Means

Set the steak on the board and find the lines running through the meat. Turn your knife so it cuts across those lines, not along them. A slight angle helps too, since wider slices feel softer than thick upright chunks.

Common Misses That Dry It Out

• Waiting too long to temp it: Start checking before you think it is ready.
• Pulling at the final number: Carryover heat keeps climbing after the steak leaves the fire.
• Skipping the rest: Slice too soon and more juice runs out.
• Cutting with the grain: Even a well-cooked flank steak will feel tougher that way.
• Using low heat for too long: The center creeps upward while the surface still struggles to brown.

If you overshoot medium, all is not lost. Slice the steak thin and pair it with something moist, like chimichurri, pan juices, or a spoon of garlic butter. It also works well in tacos, salads, grain bowls, and sandwiches where thinner slices soften the chew.

Medium Flank Steak Checklist

• Target a final temperature of 140°F to 145°F for medium.
• Pull from the heat at 135°F to 140°F.
• Rest 5 to 10 minutes before slicing.
• Use an instant-read thermometer from the side in the thickest spot.
• Slice thin across the grain.
• If you want USDA minimum doneness for whole beef cuts, finish at 145°F and rest 3 minutes.

Done well, medium flank steak gives you a browned crust, a pink center, and slices that stay pleasant bite after bite. Stay close to the thermometer, trust the rest, and let the grain tell you where to cut.
