Flank steak, a lean and flavorful cut of beef, is a popular choice for grilling, broiling, and pan-searing. Its relatively thin profile makes it quick to cook, but mastering the cooking time is crucial for achieving a tender and juicy result. This comprehensive guide explores the factors influencing flank steak cooking times, providing detailed instructions and tips to help you cook it perfectly every time.
Understanding Flank Steak
Before diving into cooking times, it’s essential to understand what flank steak is and what makes it unique. Flank steak comes from the abdominal muscles of the cow, specifically the lower chest or abdominal area. This location means it’s a hardworking muscle, resulting in a relatively tough cut with prominent muscle fibers.
The key to enjoying flank steak lies in proper preparation and cooking. Marinades are often used to tenderize the meat and infuse it with flavor. Cooking to the correct internal temperature and slicing against the grain are also vital for optimal tenderness.
Factors Influencing Cooking Time
Several factors can influence how long it takes to cook flank steak. Understanding these variables will help you adjust your cooking time accordingly.
Thickness of the Steak
The thickness of the flank steak is the most significant determinant of cooking time. A thicker steak will naturally take longer to cook than a thinner one. Flank steak is typically about 1/2 to 1 inch thick.
Cooking Method
The cooking method you choose will also affect the cooking time. Grilling, broiling, and pan-searing all involve different levels of heat and proximity to the heat source, resulting in varying cooking times.
Desired Doneness
Your preferred level of doneness will significantly impact the cooking time. Rare, medium-rare, medium, and well-done all require different internal temperatures, and thus, different cooking times.
Starting Temperature of the Steak
The starting temperature of the steak can also affect the cooking time. If the steak is cold straight from the refrigerator, it will take longer to reach the desired internal temperature than a steak that has been allowed to come to room temperature for about 30 minutes.
Cooking Time Guidelines by Method
Here’s a breakdown of cooking time guidelines for different methods, keeping in mind the factors discussed earlier. These times are estimates and should be adjusted based on the specific characteristics of your steak.
Grilling Flank Steak
Grilling is a popular method for cooking flank steak, imparting a smoky flavor and beautiful sear.
-
High Heat (450-550°F): For a 1/2-inch thick steak, grill for 3-5 minutes per side for medium-rare. For a 1-inch thick steak, grill for 5-7 minutes per side for medium-rare.
-
Medium Heat (350-450°F): For a 1/2-inch thick steak, grill for 5-7 minutes per side for medium-rare. For a 1-inch thick steak, grill for 7-9 minutes per side for medium-rare.
Note: Always use a meat thermometer to ensure accurate doneness.
Broiling Flank Steak
Broiling offers a quick and easy way to cook flank steak indoors.
-
Place the steak on a broiler pan about 4-6 inches from the heat source.
-
Broil for 4-6 minutes per side for medium-rare, depending on the thickness of the steak.
-
Watch carefully to avoid burning, as broiling can cook the steak quickly.
Pan-Searing Flank Steak
Pan-searing provides a flavorful crust and even cooking.
-
Heat a heavy-bottomed skillet (cast iron is ideal) over medium-high heat until very hot.
-
Add oil with a high smoke point, such as canola or avocado oil.
-
Sear the steak for 3-5 minutes per side for medium-rare, depending on the thickness.
-
Reduce heat if the steak is browning too quickly.
Internal Temperature and Doneness
Using a meat thermometer is the most accurate way to determine when your flank steak is cooked to your desired level of doneness. Insert the thermometer into the thickest part of the steak, avoiding bone or fat.
Here’s a guide to internal temperatures for different levels of doneness:
-
Rare: 125-130°F
-
Medium-Rare: 130-135°F
-
Medium: 135-145°F
-
Medium-Well: 145-155°F
-
Well-Done: 155°F and above
Remember that the internal temperature will continue to rise slightly after the steak is removed from the heat, a process known as carryover cooking. Therefore, it’s best to remove the steak from the heat when it’s a few degrees below your target temperature.
Marinades and Tenderness
Marinades play a crucial role in tenderizing flank steak. They contain acidic ingredients like vinegar or citrus juice, which help to break down the muscle fibers. They also add flavor to the steak.
A good marinade should include:
-
Acid: Vinegar, lemon juice, lime juice, or wine.
-
Oil: Olive oil or vegetable oil.
-
Flavorings: Herbs, spices, garlic, onions, soy sauce, Worcestershire sauce.
Marinate the flank steak for at least 30 minutes, and up to 24 hours, in the refrigerator. The longer you marinate, the more tender and flavorful the steak will be.
Tips for Perfectly Cooked Flank Steak
Here are some additional tips to help you cook flank steak perfectly:
-
Bring the steak to room temperature: Take the steak out of the refrigerator about 30 minutes before cooking to ensure even cooking.
-
Pat the steak dry: Pat the steak dry with paper towels before cooking to promote browning.
-
Use high heat: Flank steak cooks best over high heat, which helps to create a flavorful crust.
-
Don’t overcrowd the pan or grill: Cook the steak in batches if necessary to ensure proper searing.
-
Let the steak rest: After cooking, let the steak rest for 5-10 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful steak.
-
Slice against the grain: This is the most important step for tenderness. Identify the direction of the muscle fibers and slice the steak perpendicular to them. This shortens the fibers, making the steak easier to chew.
Serving Suggestions
Flank steak is a versatile cut of beef that can be served in various ways.
-
Grilled Flank Steak Tacos: Slice the steak thinly and serve it in warm tortillas with your favorite toppings.
-
Flank Steak Salad: Top a bed of greens with sliced flank steak, vegetables, and a vinaigrette dressing.
-

What is the ideal internal temperature for flank steak, and why does it matter?
The ideal internal temperature for flank steak, cooked to medium-rare, is 130-135°F (54-57°C). For medium, aim for 135-145°F (57-63°C). Using a reliable meat thermometer is essential to ensure accuracy. Avoid cooking it beyond medium, as it becomes tough and dry because it’s a lean cut with tightly packed muscle fibers.
Achieving the correct internal temperature is crucial for both safety and quality. Undercooked flank steak poses a risk of foodborne illness, while overcooked flank steak becomes chewier and less palatable. Accurate temperature control guarantees a tender, flavorful, and safe eating experience.
How long should I marinate flank steak for the best results?
Marinating flank steak enhances its flavor and tenderizes the meat. The ideal marinating time is between 2 to 12 hours. A longer marinade time, up to 24 hours, is acceptable, but avoid exceeding this limit. Excessive marinating can cause the steak to become mushy, particularly if the marinade contains acidic ingredients like citrus juice or vinegar.
The duration allows the marinade to penetrate the meat fibers, breaking them down and infusing the steak with flavor. However, prolonged exposure to acidic marinades will denature the proteins excessively, leading to undesirable texture changes. Monitor the steak’s condition and adhere to the recommended marinating window.
What are the best cooking methods for flank steak?
Flank steak thrives when cooked using high-heat methods that promote a flavorful crust and maintain a tender interior. Grilling and pan-searing are excellent choices. Broiling is another option, but requires careful monitoring to prevent burning. The key is to cook it quickly over intense heat.
Regardless of the chosen method, proper preparation is crucial. Ensure the steak is patted dry before cooking to encourage browning. Using a cast-iron skillet or a hot grill helps achieve a perfect sear. Adjust cooking times based on your desired level of doneness and the thickness of the steak.
How do I properly slice flank steak after cooking?
Slicing flank steak correctly is crucial for achieving maximum tenderness. Always slice the steak against the grain. The grain refers to the direction of the muscle fibers, which are visible as lines running along the surface of the steak.
Slicing against the grain shortens these muscle fibers, making the steak easier to chew. If you slice with the grain, you’ll be left with long, stringy fibers that are difficult to cut and more likely to be tough. Observe the grain carefully before slicing and adjust your knife angle accordingly.
Can I cook flank steak from frozen?
While it’s generally recommended to thaw meat before cooking, it’s technically possible to cook flank steak from frozen, but it’s not ideal. The primary challenge is achieving even cooking; the exterior may cook quickly while the interior remains frozen, making temperature control difficult.
If you must cook from frozen, use a low oven (around 275°F or 135°C) to thaw the steak gently. Once partially thawed, you can sear it briefly on high heat to develop a crust. Be prepared for a longer cooking time and monitor the internal temperature closely. However, the texture and flavor are generally superior when cooked from thawed.
What are some good side dishes to serve with flank steak?
Flank steak pairs well with a variety of side dishes that complement its rich flavor. Roasted vegetables, such as asparagus, Brussels sprouts, or bell peppers, are excellent choices. Their natural sweetness balances the savory flavor of the steak. A simple salad with a vinaigrette dressing also provides a refreshing contrast.
Other suitable options include mashed potatoes, rice pilaf, or grilled corn on the cob. A chimichurri sauce or salsa verde can add brightness and acidity to the dish. The versatility of flank steak allows for a wide range of pairings, so choose side dishes that suit your personal preferences.
How can I tell if my flank steak is cooked to the desired doneness without a thermometer?
While a meat thermometer is the most accurate way to gauge doneness, you can use visual and tactile cues as indicators. Press the center of the steak gently with your finger. If it feels very soft and yielding, it’s likely rare. If it feels slightly firmer but still has some give, it’s probably medium-rare.
The firmer the steak feels, the more well-done it is. A well-done steak will feel very firm with minimal give. These methods require experience and may not be completely accurate, but they can serve as a guide. Slicing into the steak slightly to check the color can also offer a glimpse of the doneness. Remember, a thermometer is always the most reliable tool.
