Flank steak. The name itself evokes images of sizzling grills and summertime barbecues. It’s a popular cut of beef, prized for its robust flavor and relative affordability. But a common question plagues aspiring grill masters: Should flank steak be cooked rare? The answer, as with many culinary queries, isn’t a simple yes or no. It depends on a variety of factors, from understanding the muscle structure of the flank steak itself to mastering the art of cooking and slicing it properly. Let’s explore the nuances of cooking flank steak rare and unlock the secrets to a tender, flavorful result.
Understanding Flank Steak: The Muscle Matters
Before delving into cooking techniques, it’s crucial to understand the nature of flank steak. This cut comes from the abdominal muscles of the cow, specifically the lower chest or abdominal area. This location gives it a distinct characteristic: long, prominent muscle fibers.
These fibers run the length of the steak, making it naturally tougher than cuts like filet mignon or ribeye, which have shorter, less dense muscle fibers. The more a muscle is used, the tougher it becomes, and the flank muscle works hard. This inherent toughness is why the question of cooking it rare is so pertinent.
Cooking flank steak rare essentially means heating it to a lower internal temperature than medium or well-done. This lower temperature can help preserve moisture, but it also means the muscle fibers have less time to break down and become tender. Therefore, careful consideration must be given to maximizing tenderness when aiming for a rare flank steak.
The Case for Rare: Flavor and Moisture Retention
The primary argument for cooking flank steak rare lies in its ability to retain moisture and deliver a richer, more intense flavor. Overcooking flank steak can quickly lead to a dry, chewy, and ultimately disappointing experience. Rare flank steak, when properly prepared, can be incredibly juicy and flavorful.
The Maillard reaction, responsible for the delicious browning and flavor development on meat, still occurs even when cooking to rare. This searing process provides the crusty exterior that complements the tender interior.
Furthermore, some argue that a rare cook allows the natural beefy flavors to shine through without being masked by the dryness and toughness associated with overcooked flank steak. The key, however, is ensuring that the steak is tender enough to enjoy despite the minimal cooking time.
The Challenges of Rare: Tenderness and Texture
The biggest hurdle in cooking flank steak rare is achieving acceptable tenderness. As mentioned earlier, the long muscle fibers of the flank steak are naturally tougher than those in other cuts. Cooking it rare means these fibers have less time to break down through heat denaturation.
If cooked improperly, rare flank steak can be unpleasantly chewy and difficult to cut. This is why many cooks opt for medium-rare or medium, believing that the slightly longer cooking time improves tenderness.
Another potential challenge is the texture. Some people may find the texture of rare flank steak too “raw” or “bloody” for their liking, even if it’s technically safe to eat. This is largely a matter of personal preference.
Essential Techniques for Cooking Rare Flank Steak: A Guide to Success
To successfully cook a tender and delicious rare flank steak, you need to employ specific techniques that compensate for the cut’s inherent toughness. Here are some crucial steps:
Marinating for Tenderness and Flavor
Marinating is arguably the most important step in preparing flank steak, especially when aiming for rare. A good marinade serves two main purposes: to tenderize the meat and to infuse it with flavor.
Marinades typically contain acidic ingredients like vinegar, citrus juice, or yogurt, which help to break down the muscle fibers. They also often include oil, herbs, and spices to add flavor complexity.
The length of marinating time is also critical. Ideally, flank steak should marinate for at least 2 hours, but no more than 24 hours. Over-marinating can result in a mushy texture.
Some popular marinade ingredients include:
- Soy sauce: Adds umami and saltiness.
- Worcestershire sauce: Enhances savory flavors.
- Olive oil: Helps distribute the marinade and retain moisture.
- Garlic and ginger: Provide aromatic complexity.
- Citrus juice (lime, lemon): Tenderizes the meat with acidity.
- Herbs (rosemary, thyme): Add fragrant notes.
High Heat Searing: Achieving the Perfect Crust
Once marinated, it’s time to sear the flank steak. High heat is essential for achieving a good crust while keeping the interior rare. This can be done on a grill, in a cast-iron skillet, or even under a broiler.
Before searing, pat the steak dry with paper towels. This helps to remove excess moisture, which can inhibit browning.
Preheat your cooking surface to high heat. You should see visible smoke emanating from the grill or skillet.
Sear the flank steak for 2-3 minutes per side, depending on the thickness of the steak and the desired level of doneness. Use a meat thermometer to ensure the internal temperature reaches the desired rare level (approximately 125-130°F).
Resting: Allowing the Juices to Redistribute
Resting the flank steak after cooking is just as important as marinating and searing. Allow the steak to rest for at least 10 minutes before slicing.
During cooking, the muscle fibers contract, squeezing out moisture. Resting allows these fibers to relax and reabsorb some of the juices, resulting in a more tender and flavorful steak.
Cover the steak loosely with foil while it rests to keep it warm.
Slicing Against the Grain: The Key to Tenderness
Slicing flank steak against the grain is absolutely crucial for maximizing tenderness. As mentioned earlier, the long muscle fibers of flank steak can make it chewy if sliced incorrectly.
“Against the grain” means slicing perpendicular to the direction of the muscle fibers. This shortens the fibers, making them easier to chew.
Identify the direction of the muscle fibers before slicing. They will be visible as long lines running across the steak.
Use a sharp knife to slice the steak thinly, at a 45-degree angle against the grain. This will further shorten the muscle fibers and enhance tenderness.
Internal Temperatures for Rare Flank Steak: A Guide
Achieving the perfect level of rare involves monitoring the internal temperature of the steak. Here’s a general guide:
- Rare: 125-130°F (52-54°C)
- Medium Rare: 130-140°F (54-60°C)
- Medium: 140-150°F (60-66°C)
Use a reliable meat thermometer to check the internal temperature. Insert the thermometer into the thickest part of the steak, avoiding bone or fat.
Remember that the internal temperature will continue to rise slightly during the resting period, so remove the steak from the heat when it’s a few degrees below your target temperature.
Beyond the Grill: Alternative Cooking Methods for Rare Flank Steak
While grilling is a popular method for cooking flank steak, other cooking methods can also yield excellent results.
Pan-Searing
Pan-searing in a cast-iron skillet is an effective way to achieve a good crust and even cooking. Use a high-heat oil like canola or grapeseed oil.
Broiling
Broiling is another option for achieving a quick sear. Place the flank steak on a broiler pan and broil for 2-3 minutes per side, keeping a close eye on it to prevent burning.
Sous Vide
Sous vide cooking involves immersing the flank steak in a temperature-controlled water bath. This method ensures even cooking and precise temperature control, resulting in a very tender and juicy steak. After the sous vide process, a quick sear in a hot pan or on the grill is still recommended to achieve a desirable crust.

FAQ: Is it safe to eat flank steak rare?
Eating flank steak rare can be safe, but it depends on a few factors. First, ensure the steak is from a reputable source and has been handled and stored properly. The primary risk with undercooked beef is bacterial contamination, such as E. coli. If you’re confident in the meat’s quality and preparation, the risk is significantly reduced, but never entirely eliminated.
Consider searing the outside of the flank steak thoroughly, even if you prefer the inside rare. This kills surface bacteria, which are the most common source of contamination. Ultimately, whether you choose to eat it rare is a personal decision based on your risk tolerance and preference for flavor and texture.
FAQ: What’s the ideal internal temperature for rare flank steak?
The generally accepted internal temperature for rare flank steak is between 125-130°F (52-54°C). Use a reliable meat thermometer to accurately measure the temperature at the thickest part of the steak. Keep in mind that the internal temperature will continue to rise slightly after you remove the steak from the heat, a process known as carryover cooking.
Allowing for carryover cooking, removing the flank steak from the heat when it reaches about 120-125°F (49-52°C) will typically result in a final internal temperature within the rare range after it rests. Resting the steak is crucial, as it allows the juices to redistribute, resulting in a more tender and flavorful final product.
FAQ: How does cooking flank steak rare affect its tenderness?
Cooking flank steak rare generally enhances its tenderness, provided it’s properly cut and prepared. Flank steak is a relatively lean cut with long muscle fibers. Cooking it rare to medium-rare keeps these fibers relatively relaxed, preventing them from becoming tough and chewy.
Overcooking flank steak, especially beyond medium, will cause the muscle fibers to tighten and expel moisture, resulting in a dry and tough steak. Therefore, keeping it rare helps maintain the moisture and allows for a more tender bite, especially when cut against the grain after cooking.
FAQ: What marinades pair well with rare-cooked flank steak?
Marinades with acidic components like citrus juice, vinegar, or wine work very well with rare-cooked flank steak. The acid helps to tenderize the meat by breaking down some of the muscle fibers, allowing for better absorption of flavor and a more pleasant texture, even when cooked rare.
Consider marinades with savory elements such as soy sauce, garlic, ginger, and herbs. These ingredients complement the beefy flavor of flank steak and enhance the overall dining experience. Marinating for at least 30 minutes, or up to several hours in the refrigerator, is recommended for optimal flavor penetration.
FAQ: What’s the best way to sear flank steak for rare cooking?
The best way to sear flank steak for rare cooking is to use high heat and a relatively short cooking time. This creates a flavorful crust on the outside while keeping the inside rare and tender. A cast-iron skillet or grill pan preheated to a high temperature works exceptionally well.
Before searing, pat the flank steak dry with paper towels to ensure proper browning. Add a high-smoke-point oil to the pan, such as avocado or grapeseed oil, and sear the steak for about 2-3 minutes per side, depending on its thickness. This creates a beautiful crust without overcooking the inside.
FAQ: Can you sous vide flank steak for a rare finish?
Yes, sous vide is an excellent method for achieving a perfectly rare flank steak. Sous vide allows for precise temperature control, ensuring that the entire steak is cooked evenly to the desired level of doneness. You can set the water bath to the desired rare temperature, such as 125-130°F (52-54°C), and cook the steak for 1-3 hours, depending on its thickness.
After the sous vide process, the flank steak will need to be seared to develop a flavorful crust. Pat the steak dry and sear it in a hot pan with oil for a minute or two per side. This combination of sous vide and searing results in a consistently rare and tender flank steak with a beautiful outer crust.
FAQ: What’s the best way to slice flank steak cooked rare?
The most crucial aspect of slicing flank steak, especially when cooked rare, is to cut against the grain. The grain refers to the direction of the muscle fibers. Cutting against the grain shortens these fibers, making the steak significantly more tender and easier to chew.
Before slicing, let the steak rest for at least 5-10 minutes to allow the juices to redistribute. Identify the direction of the grain, and then use a sharp knife to slice the steak thinly, perpendicular to the grain. This technique is essential for enjoying the full potential of a rare-cooked flank steak.
