What is Flank Steak
Flank steak is delicious for fajitas, stir fry, homemade cheesesteak, or just sliced on it’s own with some fresh vegetables.
Flank steak is meaty, rich, juicy and delicious – and is a leaner cut of steak with less marbling.
Flank steak is well known as a cut that can turn tough quickly – and needs to be cut a specific way when serving (against the grain) since it is made out of long, thick muscle strands.
How To Cook Flank Steak
Flank steak gets a bit of a bad rap for being tough – which certainly can be the case if not cooked properly - flank steak needs to cook hot and fast.
If you remember nothing from this recipe, the number one tip I can give for perfect cooked flank steak that isn't tough is to cook it HOT and FAST.
Flank steak is absolutely heavenly when sent to soak in a marinade – but, unlike other tougher cuts of steak, is also quite beautiful under a broiler or on he grill - anywhere with high heat so it can cook quickly.
Is a Flank Steak the Same as a Skirt Steak
Flank steak and skirt steak are both cut near the belly of the cow, in the “short plate” area - and in this recipe, they can be used interchangeably - just plan for a little longer cooking time for the slightly fattier and larger skirt steak.
The flank steak is lower, leaner, and has less fat marbling than skirt steak.
Can You Use Skirt Steak
Skirt steak is from a similar part of the cow as the flank steak, but has a little bit more fat and connective tissue in it (skirt steak is a little more marbled than flank steak), so it needs to break down a little more.
Luckily, skirt steak is great roasted in the oven, if you take just a couple extra steps!
If you’re having a hard time finding flank steak and grab skirt steak instead, don’t skip the skirt steak marinade (preferably overnight) and give it a quick pound with a meat tenderizer before popping it on the grill.
How To Cut Flank Steak
Since we’re using tougher cuts of beef with long, lean fibers, it is critical to cut your skirt steak or flank steak properly for tender juicy steak.
If you look at your grilled flank steak or skirt steak, you will see long lines running down the steak – you will want to cut against the grains to make them short – which makes them much softer and easier to chew since you’re breaking down the fibers holding the meat together.
Slice the grilled steak as thin as possible for the most tender and easy to chew flank steak – and be sure to wait for the steak to rest fully before slicing to help preserve the steak’s natural juices and flavor!
Steak on a Budget
If you’re throwing a dinner party or feeding a crowd, flank steak is one of the best steaks you can serve on a budget, since it is a typically inexpensive and tougher cut of beef.
Typically, skirt steak and flank steak (and other steaks well-suited to carne asada recipes) run $6-$8 per pound, making them some of the most affordable cuts of beef at the market.
To really cut the cost, look for flank and skirt steak in your grocer’s bulk case – you can often find bundles of flank steak for dollars less.
Buy in bulk to freeze for future dinners - or cook up a big batch, and portion out in different meals throughout the week!
How To Cook Flank Steak in the Oven
These tips will help you keep your flank or skirt steak from becoming too tough, chewy, or flavorless – and are so easy to do in your oven!
- Remove silver skin.
- The tough slivery skin often still on flank steak and skirt steak should be removed as much as possible – to remove it, you might need a knife point to get some of the skin loose enough to get a good grip on it and simply tear it off.
- Removing silver skin from steak is very important since it becomes tough, chewy, and offers no flavor to the grilled steak.
- Cook fast at very high heat.
- Since flank steak has very little fat and connective tissues, it can become tough when cooked too long at low temperatures.
- For perfect tender juicy flank steak you need to cook it hot and fast – broiled at high heat.
- Fully preheat oven to 500-450 degrees before adding steak (go as high and hot as you can using your oven's broiler BEFORE your steak is anywhere near the oven.)
- Marinate flank steak before grilling.
- Again, because flank steak has little fat marbling, it really benefits from a good soak in a marinade to soften the meat and help lock in tons of juicy flavor.
- Marinades are also a delicious way to add flavor to the steak – add in different herbs and spices to find a blend you love the best!
- This recipe is a very very basic marinade intentionally so you can add in other herbs you love. Some great ideas to try:
- Chinese Five Spice for a slightly sweet kick thanks to the cinnamon in the spice blend.
- Teriyaki Sauce or soy sauce for an Asian Flank Steak twist.
- Blackening spices for a cajun kick.
- Montreal Steak Spices for a zesty steak (don’t add salt if using Montreal Steak Herb mix since its already quite salty.)
- Don’t overflip.
- Part of the intense flavor from grilled steak comes from the bit of char the steak gets under the broiler – which needs time to form!
- Resist the urge to flip your flank steak too often, so your steak can get a delicious, crunchy sear on the outside.
- If making for meal prep to be reheated later, consider cooking slightly less.
- If you’re making this steak with the intention of reheating it again another day, consider cooking it a level lower than your ideal doneness so you can reheat it without making it too tough or dry from overcooking.
- This is especially important if you are microwaving to reheat! I personally love flank steak cold on taco salads though.
