PIN marinated grilled flank steak to try it later!

I first made Marinated Grilled Flank Steak years ago when a teacher at my school asked for beef recipes on the blog! Since then I’ve made this flank steak recipe many times, changing the marinade ingredients slightly each time.

Now it’s summer grilling season and the recipe was in need of better photos! So I’ve updated with new photos and also a switch to the easier marinade that’s now my favorite for steak. (If anyone was a fan of the original version, you can still see that recipe here.)

Flank steak is best when it’s cooked medium-rare or less. So if you like your beef well-done this may not be the recipe for you. But for anyone who enjoys a medium-rare steak, this grilled steak is a treat. And if you want to make the meal you see in these new photos, we ate grilled flank steak with simple Cucumbers Caesar on the side!

What is Flank Steak?

Although some people confuse flank steak with Skirt Steak, they are not the same thing. Flank Steak comes from the back abdominal area of the beef, while skirt steak is found closer to the front. Flank steak is a grainy and relatively relatively lean cut of beef that’s best when it’s been marinated, and it’s preferred rare or medium rare.

Does grilled flank steak have to be marinated?

Flank steak that’s going to be grilled with greatly benefit from a long marinating time. We marinated the meat in these pictures over night and cooked it mid-day for about 14 hours total marinating time.

More tips for cooking and serving flank steak:

• If you like your meat well-done, this might not be the recipe for you. Flank steak tastes best and is most tender when it’s cooked rare or medium-rare.
• Cook flank steak quickly at high or medium-high heat.
• Use an Instant Read Meat Thermometer (affiliate link) and remove meat from the grill when it reaches about 130F/55C for medium rare.
• Put cooked steak on a plate and cover with foil and let it “rest” for 5-10 minutes.
• Use a sharp serrated or chef’s knife to cut the flank steak into thin slices, cut it on a downward angle.
• Serve the steak hot and enjoy!

How to make Marinated Grilled Flank Steak without an Outdoor Grill:

If it’s not quite grilling weather or you don’t have an outdoor grill, you can also cook flank steak on a Stovetop Grill Pan (affiliate link) or a George Foreman Grill (affiliate link) with good results. Remember the George Foreman Grill cooks both sides at once, so don’t overcook the meat!

Two sauces to serve with the Flank Steak:

This grilled steak would be amazing with Chimichurri Sauce or Olive Sauce for Steak!

How to Make Marinated Grilled Flank Steak:

(This is only a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

1. The first photo shows the flank steak I bought for $8.99 a pound at my local Kroger store.
2. I used the recipe for Easy Steak Marinade I got from my former neighbor Carol. Stir together balsamic vinegar, fresh lime juice, Worcestershire sauce (or Gluten-Free Worcestershire Sauce), garlic powder, coarse-ground black pepper, salt, and olive oil.
3. Trim fat if, or if you prefer to keep some fat make small slits in the fat on the edges.
4. Rub meat on both sides with Szeged Steak Rub, Sugar-Free Montreal Steak Seasoning, or other steak rub.
5. Put meat in Ziploc bag, add the marinade, and marinate in refrigerator for at least 8 hours.
6. When you want to cook, drain the meat in a colander, catching the marinade in a bowl if you don’t want it to go down the sink.
7. Let flank steak come to room temperature while you preheat grill to high heat, about 450-500F or 230-260C.
8. Criss-cross grill marks are not going to show when you cut the flank, but I can’t resist them.
9. Lay the steak on an angle across the grates, and turn heat down to medium-high.
10. Cook steak 3 minutes or until you see grill marks; then rotate and cook about 3 minutes at the opposite angle.
11. Turn steak and cook about 4-5 minutes on the second side, or until meat reaches 130F/55C (for medium rare) on an instant read meat thermometer.
12. If you don’t have a meat thermometer, use the finger test. 
13. When meat reaches the temperature you want, take off the grill and place on a plate, cover with foil, and let rest 5-10 minutes.
14. Then put steak on a cutting board and use a large serrated knive or chef’s knife to cut thin slices, cutting on a diagonal against the grain.
15. Serve hot and enjoy!

Marinated Grilled Flank Steak would taste great with one of these low-carb side dishes:

Total Time 46 minutes

This Marinated and Grilled Flank Steak dinner is a low-carb meal that will please any beef lover.

Ingredients

• 1 1/2 lbs. flank steak (see notes)
• 1-2 T Steak Rub (see notes)
• 2 T balsamic vinegar
• 2 T fresh-squeezed juice (see notes)
• 1 T Worcestershire sauce (gluten-free if needed)
• 1 tsp. garlic powder
• 1/4 tsp. fresh ground black pepper
• 1/4 tsp. salt
• 2 T olive oil
• more salt and fresh-ground black pepper to season cooked steak

Instructions

1. We bought a piece of flank steak that was just over 1 1/2 lbs. for this recipe, but you can use a slightly bigger piece if you prefer.
2. For the marinade combine balsamic vinegar, fresh lime juice, Worcestershire sauce or Gluten-Free Worcestershire Sauce, garlic powder, coarse-ground black pepper, salt, and olive oil.
3. Trim fat on the edges of the flank steak if needed, or if you prefer to keep some fat make small slits in the fat pieces so the edges don’t curl up on the grill.
4. Rub meat on both sides with Szeged Steak Rub, Sugar-Free Montreal Steak Seasoning, or other steak rub of your choice.
5. Put meat in Ziploc bag, add the marinade, and marinate in refrigerator for at least 8 hours. (I sometimes put it in the fridge at night before I go to bed, then cook for dinner the next day.)
6. When you’re ready to cook drain the meat in a colander, catching the marinade in a bowl if you don’t want it to go down the sink.
7. Let flank steak come to room temperature while you preheat the grill to high heat, about 450-500F or 230-260C.
8. If you want grill marks, lay the steak on an angle across the grill grates, and turn heat down to medium-high if you can adjust it.
9. Cook steak about 3 minutes or until you see grill marks when you lift the edge; then rotate and cook about 3 minutes at the opposite angle.
10. Turn steak over and cook about 4-5 minutes on the second side, or until the meat reaches 130F/55C for medium rare when you test with an instant read meat thermometer. If you don’t have a meat thermometer, use the finger test. (The meat will continue to cook while it rests so if you want it quite rare, take it off the grill a bit sooner.
11. When meat reaches the temperature you want, take it off the grill and place on a plate, cover with foil, and let rest 5-10 minutes
12. Then put the steak on a cutting board and use a large serrated knife or chef’s knife to cut thin slices, cutting on a diagonal against the grain.
13. Serve hot. the Marianted Grilled Flank Steak would be great served with Chimichurri Sauce or olive sauce for steak.

Notes

You can use Szeged Steak Rub (affiliate link), Sugar-Free Montreal Steak Seasoning, or other steak rub of your choice.

I used my fresh-frozen lime juice.

This recipe was updated with Easy Steak Marinade to marinate the flank steak, which is the one I have preferred for many years now.
