What is Flank Steak?

marinated steak is a cut of beef that comes from the lower abdominal muscles of the cow, specifically the flank area, just below the loin. Known for its long, flat shape and bold flavor, marinated steak is a lean and versatile cut that can be used in a variety of dishes. Unlike more marbled cuts like ribeye or strip steak, marinated steak has less fat, which gives it a robust, meaty taste but also requires careful preparation to ensure tenderness.

Key Characteristics of Flank Steak

Texture: marinated steak is a lean cut with visible muscle fibers running lengthwise. This gives it a firm texture, which is why it’s essential to cut it against the grain to avoid chewiness.
Flavor: marinated steak is known for its deep, beefy flavor. While it doesn’t have the buttery richness of fattier cuts, it absorbs marinades exceptionally well, making it a favorite for dishes that require bold seasoning.
Size and Shape: marinated steak is typically rectangular and flat, with an average weight ranging from 1 to 2 pounds. Its thin profile makes it ideal for quick cooking methods like grilling and pan-searing.

Where Does Flank Steak Come From?

marinated steak is sourced from the underside of the cow, in a section that sees a lot of movement. This is why the cut has a strong, fibrous structure—it’s a working muscle. Unlike cuts from the rib or loin areas, which are naturally tender due to less activity, marinated steak benefits from techniques like marinating and proper slicing to enhance its tenderness.

The Popularity of Flank Steak

Flank steak has grown in popularity because it strikes a balance between affordability and flavor. While it’s slightly tougher than premium cuts, its rich taste and versatility make it a go-to choice for a range of cuisines. From Latin-inspired fajitas to Korean-style BBQ, flank steak can be adapted to suit countless recipes. It’s also relatively easy to prepare, requiring minimal trimming and straightforward cooking techniques.

The Nutritional Profile of Flank Steak

Flank steak is a lean source of protein, making it an excellent choice for health-conscious individuals. It contains essential nutrients such as iron, zinc, and B vitamins while being lower in fat compared to more marbled cuts. A typical 3-ounce serving of grilled flank steak provides about 23 grams of protein and only 6 grams of fat, making it a healthy option for those looking to build muscle or maintain a balanced diet.

Understanding the basics of marinated steak is the first step in mastering this versatile cut. From its origins to its flavor profile, it’s a cut that offers tremendous value and versatility in the kitchen.

Flank Steak vs Other Cuts

grilled flank steak is a unique and versatile cut of beef, but it often gets compared to other similar cuts like skirt steak and hanger steak. Understanding the differences between these cuts is essential for choosing the right one for your recipe and ensuring the best cooking results. Each cut has its own texture, flavor profile, and ideal preparation methods, making them suited to different dishes and preferences.

Flank Steak vs Skirt Steak

Flank steak and skirt steak are frequently mistaken for one another due to their similar long and flat shapes. However, they come from different parts of the cow and have distinct characteristics:

Location: grilled flank steak is cut from the lower abdominal muscles, while skirt steak comes from the diaphragm area.
Texture: Skirt steak is even more fibrous and has a looser grain than grilled flank, which makes it slightly more tender when cooked properly.
Flavor: Skirt steak tends to have a more intense beefy flavor, while flank steak is milder and pairs well with a broader range of marinades and seasonings.
Cooking Methods: Both cuts work well with quick, high-heat cooking methods, but skirt steak’s thinner profile makes it ideal for ultra-fast searing or grilling.
Best Uses: Skirt steak is a classic choice for fajitas and tacos, while flank steak is more versatile, working beautifully in stir-fries, salads, and wraps.

Flank Steak vs Hanger Steak

Hanger steak, often referred to as the “butcher’s steak,” is another alternative to grilled flank steak, but it is rarer and slightly more tender. Here’s how they compare:

Location: Hanger steak is taken from the plate section, near the diaphragm, and is a single cut from each cow. grilled flank, by contrast, is more abundant.
Texture: Hanger steak is known for its tenderness, with finer marbling than flank steak, giving it a more delicate texture when cooked properly.
Flavor: Both cuts are flavorful, but hanger steak has a richer, almost liver-like taste that some people adore. grilled flank, on the other hand, has a cleaner, beefier flavor that pairs well with marinades.
Cooking Methods: Hanger steak is best cooked to medium rare for maximum tenderness, while flank steak can handle a slightly wider range of doneness levels if prepared properly.
Best Uses: Hanger steak is ideal for dishes like steak frites or served simply with a sauce, while flank steak excels in recipes with bold marinades and high-heat cooking methods.

Flank Steak vs Sirloin or Ribeye

Unlike flank steak, which is lean and relatively inexpensive, sirloin and ribeye are premium cuts with more fat and tenderness. Here’s how they differ:

Fat Content: Ribeye and sirloin are well-marbled, providing a buttery texture and richer flavor. Flank steak, being lean, has a firmer texture and a slightly more intense beefy taste.
Price Point: Flank steak is generally more affordable than ribeye or sirloin, making it a budget-friendly option for families and large gatherings.
Cooking Methods: While ribeye and sirloin are often best suited for grilling or pan-searing without much seasoning, flank steak benefits from marinades and slicing techniques to enhance its flavor and tenderness.

When to Choose Flank Steak Over Other Cuts

Flank steak is the perfect choice when you want a lean, flavorful cut that can handle bold marinades and high-heat cooking methods. Its affordability and versatility make it ideal for weeknight meals, meal prepping, and crowd-pleasing dishes like fajitas, stir-fries, and steak wraps.

If tenderness is a priority and budget is less of a concern, cuts like ribeye or hanger steak might be a better fit. However, for recipes that rely on a lean and flavorful protein base, flank steak remains unmatched.

By understanding these differences, you can make informed choices at the butcher counter and select the right cut for your recipe every time.

Buying the Best Flank Steak

Choosing the right flank steak at the butcher or grocery store is key to achieving the best flavor and texture in your dishes. While this cut of beef is widely available, paying attention to quality and freshness can make all the difference. Here are some tips for selecting the perfect cut.

What to Look For in Flank Steak

When shopping for flank steak, focus on the following factors to ensure you’re getting a high-quality piece of meat:

Color: Look for a deep red color, indicating freshness. Avoid steak with brown or gray spots, as these may be signs of oxidation or aging past its prime.
Texture: Flank steak has visible muscle fibers, but it should still feel relatively firm and smooth to the touch. Avoid cuts that feel overly tough or dry.
Marbling: While this cut of beef is naturally lean, some small streaks of fat (called marbling) can enhance the flavor. Choose a cut with minimal but evenly distributed marbling for the best results.
Thickness: A good flank steak will have a consistent thickness throughout, ideally about ½ to 1 inch thick. Uneven cuts may cook inconsistently, leaving some parts undercooked and others overdone.

Grass-Fed vs. Grain-Fed Flank Steak

One important consideration when buying flank steak is whether to choose grass-fed or grain-fed beef. Each has its unique qualities:

Grass-Fed Flank Steak: This type of beef comes from cows raised on pasture and fed a natural diet of grass. It tends to be leaner and has a slightly earthier flavor. Grass-fed beef is also higher in omega-3 fatty acids and certain vitamins, making it a healthier choice for many consumers.
Grain-Fed Flank Steak: Cows that are grain-fed typically produce beef with more marbling and a richer, buttery flavor. While it may not be as lean as grass-fed beef, grain-fed flank steak is often more tender and has a flavor profile that appeals to a wider audience.

Choose based on your flavor preferences, dietary needs, and budget, as grass-fed beef can be slightly more expensive than grain-fed options.

When buying flank steak, understanding the labels can help you make an informed decision:

USDA Grades: In the United States, beef is graded as Prime, Choice, or Select based on its quality. Prime flank steak will have the best flavor and tenderness but may be harder to find and more expensive. Choice is a great middle-ground option, offering good quality without breaking the bank. Select is leaner and more affordable but may require extra effort to tenderize.
Certified Organic: Organic beef ensures that the cows were raised without antibiotics or hormones and were fed organic feed. This can be a good option if you prioritize natural farming practices.
Dry-Aged or Wet-Aged: Some butchers offer aged flank steak, which can have a more concentrated flavor. Wet-aged beef is stored in vacuum-sealed packaging, while dry-aged beef is exposed to air in a controlled environment to intensify flavor. Both options can elevate the taste of flank steak but come at a premium price.

Shopping at a Butcher vs. Grocery Store

While grocery stores offer convenience, purchasing flank steak from a local butcher can provide higher quality and fresher options. Butchers can also help you select the perfect cut, offer cooking advice, and even trim the steak for you if needed. However, if you’re shopping at a supermarket, check the packaging for signs of freshness, like a tight vacuum seal and no excess liquid.

Pro Tips for Buying Flank Steak

Check the Expiration Date: Always verify the sell-by or expiration date to ensure the meat is fresh.
Ask Questions: Don’t hesitate to ask your butcher about the origin of the beef, the feeding practices, or recommendations for preparation.
Buy in Bulk: Flank steak freezes well, so consider buying in bulk during sales and storing extra cuts in the freezer for future use.

Flank Steak Pricing

Flank steak is one of the more affordable cuts of beef, typically costing less than premium cuts like ribeye or filet mignon. Prices can vary depending on the grade (Prime vs. Choice), whether it’s grass-fed or grain-fed, and where you purchase it. Expect to pay anywhere from $10 to $20 per pound, depending on these factors.

Investing in a high-quality flank steak ensures a better cooking experience and superior flavor. With these tips in mind, you’ll be well-prepared to choose the perfect cut for your next meal.

Preparing Flank Steak for Cooking

Flank steak’s lean structure and pronounced muscle fibers make preparation critical for achieving the best texture and flavor. With the right techniques, you can transform this affordable cut into a tender, flavorful centerpiece for your dish. Here’s how to properly prepare flank steak before cooking.

Trimming Flank Steak

Flank steak typically comes trimmed, but some cuts may still have a silver skin or excess fat on the surface. Removing these parts ensures better cooking and presentation:

Silver Skin Removal: The silver skin is a tough, shiny membrane that won’t break down during cooking. Use a sharp knife to gently lift and slice it away, being careful not to remove too much of the meat.
Excess Fat: While flank steak is naturally lean, some cuts may have small patches of fat. Trim these for a cleaner, more consistent bite.

Why Tenderizing is Essential

Flank steak is known for its firm texture, so tenderizing helps break down the tough fibers for a softer chew. Here are two common tenderizing techniques:

Mechanical Tenderizing: Use a meat mallet or a fork to lightly pound or pierce the steak. This breaks up the muscle fibers and makes the steak more tender. Be sure not to overdo it, as pounding too hard can result in uneven thickness.
Marinade Tenderizing: Acidic ingredients in marinades, such as citrus juice, vinegar, or yogurt, help break down proteins, resulting in a more tender texture. Marinades also infuse the meat with flavor, making this method a double win.

Marinating Flank Steak for Maximum Flavor

Marinating is a crucial step for flank steak because it not only tenderizes but also enhances the flavor. A good marinade includes three essential components:

Acid: This could be lemon juice, lime juice, balsamic vinegar, or even wine. Acid breaks down tough fibers in the steak.
Oil: Olive oil or other neutral oils help the marinade coat the meat evenly and prevent drying during cooking.
Seasoning: Garlic, herbs, soy sauce, honey, and spices like cumin or paprika can add depth and boldness to the flavor profile.

How to Marinate Flank Steak:

Place the steak in a resealable plastic bag or shallow dish.
Pour the marinade over the steak, ensuring it’s fully coated.
Seal the bag or cover the dish with plastic wrap and refrigerate. Let the steak marinate for at least 2 hours, but ideally 6-8 hours for maximum flavor. Avoid marinating for more than 24 hours, as the acid can begin to break down the meat too much.

Bringing the Steak to Room Temperature

Before cooking, remove the marinated flank steak from the fridge and allow it to come to room temperature for 20-30 minutes. Cooking cold steak can lead to uneven doneness, with the exterior cooking too quickly while the interior remains underdone.

Seasoning Flank Steak

While marinades are excellent for flavor, seasoning the steak just before cooking enhances its surface taste. Lightly pat the steak dry with paper towels to remove excess marinade, then sprinkle it generously with salt and freshly cracked pepper. You can also add additional spices like smoked paprika, garlic powder, or chili flakes for extra flavor.

Pro Tip: Scoring the Surface

Scoring the surface of the flank steak can help the marinade penetrate deeper and also prevent the meat from curling during cooking. Use a sharp knife to make shallow cuts in a crisscross pattern across the steak, ensuring the cuts don’t go too deep.

Optional Pre-Cooking Step: Sous-Vide for Tenderness

For those who want guaranteed tenderness, sous-vide cooking is an excellent option before searing or grilling. Vacuum-seal the flank steak and cook it in a water bath at 130°F (54°C) for 1-2 hours. Afterward, sear it quickly on high heat to develop a crust. This method locks in juices and creates perfectly tender steak every time.

Key Mistakes to Avoid During Preparation

Skipping the Marinade: Flank steak’s lean structure benefits greatly from marinating. Skipping this step may result in a tougher texture.
Not Drying the Steak: Excess marinade can cause the steak to steam rather than sear during cooking, preventing that delicious crust from forming.
Using the Wrong Knife: When trimming or scoring flank steak, always use a sharp knife to avoid tearing the meat.

Preparing flank steak properly sets the stage for flawless cooking. With these techniques, you’ll ensure your steak is tender, flavorful, and ready to shine in any recipe.

What is the best way to cook flank steak?

Flank steak is best cooked with high-heat methods like grilling, broiling, or pan-searing. These methods help achieve a flavorful crust while keeping the inside tender and juicy. Always slice it thinly against the grain to enhance tenderness.

How should I store cooked flank steak?

To store cooked flank steak, let it cool to room temperature before placing it in an airtight container or tightly wrapping it in aluminum foil. It can be stored in the refrigerator for up to 3–4 days or in the freezer for up to 3 months. Label your container to keep track of the storage time.

Can flank steak be reheated without becoming tough?

Yes, flank steak can be reheated without becoming tough if done correctly. Avoid high heat, which can overcook the steak. Instead, use methods like reheating in a skillet with a little broth or water, or placing it in the oven at a low temperature while covered with foil to retain moisture.

Is flank steak the same as skirt steak?

While flank steak and skirt steak are similar, they come from different parts of the cow. Flank steak comes from the abdominal muscles, while skirt steak is from the diaphragm. Both are lean and flavorful, but flank steak is slightly thicker and more versatile for various recipes.

What marinades work best with flank steak?

Marinades with acidic ingredients like citrus juice, vinegar, or yogurt are excellent for tenderizing flank steak. Adding oil, garlic, herbs, and spices complements the steak’s bold flavor. Allow the steak to marinate for at least 2 hours or overnight for maximum flavor absorption.

How do I know when my flank steak is done?

Use a meat thermometer to determine doneness:

Rare: 125°F (51°C)
Medium-rare: 135°F (57°C)
Medium: 145°F (63°C)
Avoid overcooking, as flank steak is lean and can dry out easily. Let the steak rest for 5–10 minutes before slicing to preserve its juices.
