Can I substitute flank steak for flat iron steak in a recipe?
While flank steak and flat iron steak can be used in similar dishes, they have some differences that may affect the final result. Flank steak is a long, lean cut of beef that is often used in fajitas, stir-fries, and other high-temperature cooking methods. It has a lot of connective tissue, which can make it tougher and more chewy. On the other hand, flat iron steak is a more tender and flavorful cut of beef that is taken from the chuck area. It has a rich, beefy flavor and a velvety texture.
If you want to substitute flank steak with flat iron steak, keep in mind that the cooking time may be shorter due to the flat iron’s tenderness. You can still achieve the same level of doneness, but it will take less time. Additionally, you can reduce the cooking temperature if you’re looking for more even cooking and a less charred exterior. However, if you’re looking for a more traditional fajita-like texture and flavor, flank steak might still be the better choice.
There’s also another key difference: cooking methods. Since flank steak is often grilled or stir-fried, you can keep the method the same when using that cut. However, if you want to use flat iron steak for a specific dish, such as searing it in a pan or oven-roasting, you might want to adjust the cooking method according to how you intend to cook it. Keep in mind that the rich flavor and tender texture of flat iron steak will shine in more low-and-slow cooking methods or pan-searing, so these may be the best ways to showcase the meat’s potential.
Which cut of steak is more affordable, flank or flat iron?
When it comes to affordability, the choice between flank steak and flat iron steak often depends on various factors, including location, market prices, and grocery store selections. Generally speaking, flank steak tends to be a more budget-friendly option. This lean cut of beef is taken from the belly of the cow, near the hind leg. Its relatively lower price is due to a few factors: it’s a tougher cut, meaning it may require more cooking time and techniques to achieve tenderness, and there’s a relatively larger quantity cut out for this part of the meat typically being obtained.
On the other hand, the flat iron steak is a relatively new cut, named for its resemblance to the flat iron tool. It’s derived from the shoulder blade area and has gained popularity in recent years for its rich flavor, fine texture, and slightly firmer texture compared to traditional steak cuts. Due to its popularity, especially among chefs and steak aficionados, flat iron steak tends to come with a higher price tag. This can often lead to a roughly 20-30% increase in cost compared to its more budget-conscious counterpart, the flank steak.
However, it’s worth noting that, when cooked correctly, both steak options can be incredibly delicious. If a person has $15 to spend on a steak, they could opt for the flatter, more budget-friendly option.
What are the best cooking methods for flank steak and flat iron steak?
For flank steak, which is a lean cut, high heat and quick cooking methods are best to prevent it from becoming too tough. One of the most popular methods is grilling, where the steak is cooked over direct medium-high heat for 3-5 minutes per side, depending on the desired level of doneness. Another method is pan-searing, where the steak is cooked in a hot skillet with a small amount of oil, and then finished in the oven. This method allows for even cooking and a nice crust on the outside. It’s also common to use a broiler or a skillet with a piece of parchment paper to cook flank steak, depending on the desired texture and maillard reaction.
For flat iron steak, a beautifully marbled cut, lower to moderate heat methods are often preferred to bring out its rich flavor and tender texture. Pan-frying or sautéing is a great method for flat iron steak, where it’s cooked in a hot skillet with a moderate amount of oil to brown the surface and cook the interior. This method allows for even cooking and the ability to coat the steak with aromatics and spices during cooking. Oven broiling or grill roasting is another option for cooking flat iron steak, where it’s cooked at a moderate heat to prevent it from becoming too charred. A more unique method for flat iron steak is using a grill pan with a slight crust on each side, and then finishing it in the oven to complete cooking.
The choice of cooking method ultimately depends on the desired result and the tools available. Both flank steak and flat iron steak can be cooked using a variety of methods, but grilling and pan-searing tend to work well for flank steak, while pan-frying and oven roasting work well for flat iron steak.
Are flank steak and flat iron steak suitable for grilling?
Both flank steak and flat iron steak are suitable for grilling, but they do require some care to achieve the best results. Flank steak, in particular, needs to be marinated or seasoned heavily to balance its relatively tough texture. This cut is known for its robust flavor, and the acidity and spices in a marinade can help break down the fibers slightly, making it more tender and easier to chew when grilled. When cooking flank steak on a grill, it’s essential to cook it over high heat, with an internal temperature of at least 130-140°F (54-60°C) for medium-rare and then let it rest for a few minutes before slicing against the grain.
Flat iron steak, on the other hand, is typically considered a more tender cut than flank steak, and has a more delicate flavor. Due to its relatively lean nature, it can dry out quickly if overcooked, so it’s crucial to cook it over medium-high heat for a shorter amount of time. A 4- to 6-minute cooking time per side should be sufficient for a medium-rare finish, with an internal temperature of around 130-135°F (54-57°C). Additionally, as with flank steak, it’s best to slice flat iron steak against the grain after it’s rested, which helps to prevent it from tearing and makes it easier to chew.
Can I use flank steak or flat iron steak in a slow-cooked recipe?
Both flank steak and flat iron steak can be adapted for slow-cooked recipes, but they may behave slightly differently due to their unique characteristics. Flank steak, known for its rich, beefy flavor, has a leaner texture that can become tender and fall-apart when cooked slowly. However, its higher risk of drying out due to its tenderness makes it essential to keep the slow cooking liquid rich and moisture-rich to prevent it from becoming tough.
Flat iron steak, on the other hand, has a more even marbling compared to flank steak, which makes it less prone to drying out. Its tenderness and rich flavor make it suitable for slow-cooked dishes without excessive moisture additions, and it’s likely to retain its flavor and texture with less effort to moisten it over the long cooking process.
Overall, both options can be suitable for slow-cooked recipes. Choosing the one that suits your taste can be based on the level of moisture retention you’re aiming for in your recipe. If you’re aiming for a dish with plenty of flavorful liquid involved, use flank steak, while for a dish that’s dryer and richly flavored, an expertly seasoned flat iron cut is your best bet.
Are there any alternative names for flank steak and flat iron steak?
Yes, flank steak has several alternative names, which can be found depending on the region or country. Some of the common names for flank steak include skirt steak, fajita steak, or London broil. The name ‘skirt steak’ specifically refers to the diaphragm area of the cow, and it’s often known for its rich flavor and distinctive texture. Skirt steak is widely popular in Mexican cuisine and is often used in fajitas and other dishes.
Flat iron steak, also known as flat cut steak, has relatively fewer alternative names. However, it’s sometimes referred to as top blade steak in the United States, and top sirloin or top of the round steak in other countries.

How can I tell if flank steak or flat iron steak is cooked to the right doneness?
Both flank steak and flat iron steak can be challenging to cook to the right doneness due to their thickness and composition. One common method to check the doneness is by using a meat thermometer. Insert the thermometer into the thickest part of the steak, avoiding any fat pockets. For medium-rare, the internal temperature should be at least 130°F (54°C) for flank steak and 126-128°F (62-53.4°C) for flat iron steak. For medium, the internal temperature should be around 135-140°F (57-60°C) for flank steak and 132-136°F (56-57.8°C) for flat iron steak. For medium-well, the internal temperature should be around 140-145°F (60-63°C) for flank steak and 138-142°F (58.9-61.7°C) for flat iron steak.
Another method to check the doneness is by touch and visual inspection. For flank steak, medium-rare is often achieved when it is cooked for about 3-5 minutes per side. The color of the steak will be pink, and the surface should feel slightly firmer than medium-rare for flat iron steak. For medium, the steak should be cooked for about 5-7 minutes per side, with a slightly firmer surface and a hint of pink color. For medium-well, the steak should be cooked for about 7-10 minutes per side, with a fully browned surface and a hint of pink color.
For flat iron steak, it is recommended to cook it to medium-rare or medium to avoid overcooking. When cook flat iron steak to medium, the internal temperature should be about 132°F (57°C) to avoid overcooking the meat and making it dry. If you prefer your steak more well-done, it is better to choose other types of steak, as flat iron steak can become tough and dry when overcooked.
In any case, the best way to ensure that your steak is cooked to the right doneness is by using a combination of the thermometer, touch, and visual inspection methods. This way, you can get a more accurate idea of the steak’s doneness and avoid overcooking it.
Can I freeze flank steak or flat iron steak?

After thawing, cook the steak according to your preferred method, whether it’s grilling, pan-frying, or oven roasting.
Are there any specific dishes that flank steak or flat iron steak is best suited for?
Flank steak and flat iron steak are both lean cuts of beef, known for their bold flavors and chewy texture. They pair well with bold flavors and marinades, which help to tenderize the meat and bring out its natural flavors. Flank steak is a classic choice for fajitas, as its high acidity and spices complement the vibrant flavors of sautéed onions and bell peppers. Alternatively, its bold flavor profile makes it an excellent match for Asian-inspired dishes, such as a Korean-style BBQ with a sweet and spicy marinade.
Flat iron steak, while similar to flank steak, has a more tender texture and a milder flavor, making it suitable for more refined dishes. It’s an excellent choice for a grilled or pan-seared steak, served with a simple sauce like Béarnaise or Peppercorn. The milder flavor of flat iron steak also makes it a great accompaniment to delicate sides, such as roasted vegetables or a light salad. Additionally, its robust texture allows it to hold its own against rich, savory sauces, making it a popular choice for dishes like steak au poivre.
In terms of specific regional cuisines, flank steak and flat iron steak are both well-suited for traditional Tex-Mex and Latin American dishes, where bold flavors and spices are a hallmark. Flank steak is also a staple in Korean and Japanese cuisine, where it’s often marinated in a sweet and spicy sauce before being grilled or stir-fried. Flat iron steak, on the other hand, is more commonly found in upscale steakhouses and fine dining establishments, where its milder flavor and tender texture are showcased through elegant sauces and sides.
Do I need to let flank steak or flat iron steak rest after cooking?
Resting a steak, such as flank steak or flat iron steak, after cooking is an essential step in achieving optimal tenderness and juiciness. When you cook a steak, the heat causes the proteins to contract and tighten the fibers, which can make the meat harder and less appealing to eat. Resting the steak allows the proteins to relax, redistributing the juices and tenderizing the fibers. As a result, the steak becomes more tender and flavorful.
The resting time may vary depending on the thickness of the steak and the cooking method used. In general, it’s recommended to let the steak rest for 5-10 minutes after cooking. This allows the juices to redistribute and the meat to relax. During this time, you can cover the steak with a loose lid or a piece of foil to keep it warm and retain the heat. If you’re serving the steak immediately, you can also let it rest for 2-3 minutes, but at least some resting time is beneficial.
Resting the steak is especially important for cuts like flank steak or flat iron steak, which can be more prone to drying out due to their lean nature and lack of marbling. Allowing the steak to rest gives the juices a chance to redistribute, making the steak more tender and flavorful. So, always make sure to let your steak rest before serving, and you’ll be rewarded with a more enjoyable and satisfying dining experience.
How should I slice flank steak and flat iron steak?
When preparing flank steak and flat iron steak for grilling, slicing plays a crucial role in presentation and eating experience. For the flank steak, typically cut in a pinwheel or Against the grain pattern, cut the entire steak at once and slice it in a parallel direction to the lines, or what’s known as the ‘grain.’ A diagonal cut would be incorrect, as it makes the beef harder to chew. This will also provide a visually appealing presentation. Slice it in 1/16-inch thickness for ideal results.
On the other hand, flat iron steak is often more lenient when it comes to cutting. Because it’s taken from the chuck, it can have varying fibers and tenderness, from one part to the next. Therefore, the cut should be made, also at an angle but more delicately since it can have its own set fibers that can make it disjointed and harder to eat in some parts than others. Cutting it against the grain, and ensuring even distribution throughout, is recommended. Typically sliced at the thickness of 1/8 inch for the most favorable results.
It’s also worth noting that both flank steak and flat iron may benefit from being marinated. Cutting the thickness according to recommendation is often more worth it when accompanied by other recipes to elevate its taste, presenting optimal chewing and enjoyable flavors.
