Part 1: Preparing to Cut Flank Steak
1. Introduction
Flank steak is a lean and flavorful cut of beef that requires special attention when slicing to make sure it remains tender. One of the most crucial factors in preparing flank steak is cutting it correctly, especially against the grain. This technique breaks down the muscle fibers, creating a more tender bite, and it’s essential whether you’re using the steak for fajitas, salads, or grilled dishes. Proper cutting plays a significant role in both flavor and texture, ensuring the best possible results.
Whether you’re grilling or broiling, knowing how to slice flank steak is just as important as cooking it properly.

The benefits of slicing correctly go beyond texture, allowing you to serve this versatile cut in a range of dishes.
2. Why Cutting Flank Steak Properly Matters
Cutting flank steak correctly is all about texture, and understanding how the muscle fibers in the meat affect your bite is key to getting the most out of this cut. The muscle fibers in flank steak run lengthwise, which means that if you cut with the grain, you’re leaving these long fibers intact. These fibers make the meat tough and chewy when cooked, so it’s important to break them up by cutting against the grain.
By slicing against the grain, or perpendicular to the muscle fibers, you create shorter fibers in each piece of steak, which makes the meat much easier to chew. Cutting this way transforms what could be a tough steak into something tender and enjoyable. In contrast, cutting with the grain keeps those fibers long and stringy, making each bite harder to chew.
Cutting methods also vary depending on the type of steak you’re working with. For example, cuts like ribeye or tenderloin have more fat marbling, which helps keep the steak tender, regardless of how you slice it. However, with a lean cut like flank steak, slicing against the grain is essential to achieving a tender result.
Improper slicing can turn a perfectly cooked steak into a tough meal, so always make sure to identify the grain and slice accordingly. Once you master this technique, you can confidently serve flank steak in any dish, knowing that the texture will be just right.
3. Tools You Need to Cut Flank Steak
Having the right tools is just as important as the cutting technique when it comes to preparing flank steak. The quality of your tools can make the difference between an easy, clean cut and a jagged, uneven slice. Here are the essential tools you’ll need to slice flank steak perfectly:
- Chef’s Knife or Carving Knife: A sharp, high-quality knife is the most important tool when slicing steak. A chef’s knife is versatile and commonly used in most kitchens, but a carving knife with a longer blade can be helpful when slicing larger cuts like flank steak. The long, thin blade of a carving knife allows you to make precise cuts without tearing the meat. Avoid using a serrated knife, as the jagged edges can shred the steak rather than slice it cleanly.
- Cutting Board: Choose a sturdy cutting board, preferably one with grooves to catch any juices that flow from the steak as you slice. This helps keep your workspace clean and prevents slipping while cutting. A larger cutting board gives you more room to work, which is important when handling a large cut like flank steak.
- Optional Tools:
- Meat Tenderizer: Although not always necessary, a meat tenderizer can help if your flank steak is particularly tough. Gently pounding the steak before cooking can help break down some of the muscle fibers, making it easier to slice and more tender to eat.
- Knife Sharpener: A dull knife is not only harder to use but can also tear the meat rather than slice through it cleanly. Make sure to sharpen your knife before cutting to get smooth, precise slices. A knife sharpener is a useful tool to keep your blades in top shape.
Using these tools will make the cutting process smoother, ensuring your slices are even and your flank steak retains its juices and texture.

4. Preparing the Flank Steak for Cutting
Before you even begin cutting flank steak, it’s important to properly prepare the meat to get the best results. A few key steps before cutting can guarantee that your steak slices cleanly and retains its flavor and tenderness.
Resting the Steak
After cooking, the first step is to let the steak rest for at least 10 minutes. This resting period is crucial because it allows the juices within the steak to redistribute throughout the meat. Cutting into the steak immediately after cooking can cause the juices to spill out, leaving the meat dry. By allowing the steak to rest, you make sure that it stays moist and flavorful when sliced.
- Tip: Cover the steak loosely with aluminum foil while it rests to keep it warm without trapping too much steam, which can affect the crust.
Trimming Excess Fat and Silver Skin
Once the steak has rested, inspect it for any excess fat or silver skin (a tough membrane on the outside of some cuts). Removing these elements can make the steak easier to slice and improve the final texture. While flank steak is generally lean, some pieces may have a layer of fat or silver skin that you’ll want to trim away.
Use a sharp knife to carefully trim off any large pieces of fat or silver skin. Be careful not to remove too much of the meat in the process, as this could reduce the size of your steak.
Drying the Steak
Finally, pat the steak dry with paper towels before cutting. This removes any excess moisture that could cause the knife to slip, leading to uneven cuts. Drying the steak also helps maintain a clean cutting surface and guarantees your slices are precise.
Preparing the steak properly sets the stage for clean, even slices that retain their flavor and tenderness. With these steps completed, you’re ready to begin cutting.
5. Cutting the Flank Steak Against the Grain
Now that the steak is prepped, it’s time to cut it against the grain, which is the most important step in slicing flank steak. Cutting against the grain means slicing perpendicular to the direction in which the muscle fibers run. These fibers are easy to see on a flank steak—they appear as long, visible lines running across the meat.
Step-by-Step Instructions for Cutting Against the Grain:
- Identify the Grain: Start by looking at the steak and identifying the direction of the muscle fibers. They will run parallel to each other across the width of the steak.
- Position the Steak: Place the steak on your cutting board so that the grain runs from left to right, perpendicular to where you’ll be cutting.
- Start Slicing: Using a sharp knife, make thin, even slices perpendicular to the grain. Aim for slices that are about 1/4 inch thick for most recipes. Thinner slices make the meat more tender.
- Cut at an Angle: To create wider slices, angle your knife slightly as you cut. This technique is especially useful when you need larger pieces, such as for sandwiches or fajitas.
Why Cutting Against the Grain is Crucial
When you cut against the grain, you break up the long muscle fibers, making each piece of steak easier to chew. If you were to cut with the grain, the fibers would remain long and intact, resulting in a tougher, chewier bite. The thinner the slice, the shorter the muscle fibers, and the more tender the steak will be.
Cutting against the grain also helps the steak hold up better in sauces and marinades, as the shorter fibers absorb liquid more easily. This method guarantees that the steak remains flavorful and tender, no matter how it’s served.

6. Alternative Cutting Techniques for Different Recipes
Depending on the dish you’re preparing, you may need to adjust your slicing technique. Different recipes call for different cuts, so knowing how to modify your approach can help you get the best results from your flank steak.
Thick Slices for Fajitas
For recipes like fajitas, where you want larger, more substantial pieces of steak, you’ll want to cut thicker slices. Aim for slices that are around 1/2 inch thick. These thicker cuts hold up well to marinades and can be grilled or seared without losing their shape.
- Tip: Even when cutting thicker slices, always make sure you’re slicing against the grain to maintain tenderness.
Thin Slices for Salads or Sandwiches
For salads or sandwiches, where the steak is served cold or at room temperature, thinner slices are usually preferred. Thinner cuts allow the steak to be easily layered or tossed with other ingredients, making the dish more cohesive. Aim for slices that are no more than 1/4 inch thick.
Cold steak is easier to slice thinly than hot steak, so if you’re preparing steak for a salad or sandwich, consider refrigerating it for a short time before slicing. This helps firm up the meat, making it easier to get clean, even slices.
Adjusting Technique for Hot vs Cold Steak
When slicing hot steak, you’ll need to be more careful, as the juices are still settling within the meat. Use slow, deliberate cuts to avoid pressing down on the steak too hard, which can cause it to lose moisture.
For cold steak, a firmer texture allows you to slice more quickly and evenly. If you’re working with leftovers or prepping for meal prep, cold steak slices beautifully when using a sharp knife.
Part 2: Cooking Tips, FAQs, and Expert Advice
7. Should You Cut Flank Steak Before or After Cooking?
One common question when preparing flank steak is whether to cut it before or after cooking. While both methods can work depending on the dish, most experts agree that slicing the steak after cooking leads to better results for most recipes.
Cutting Before Cooking
Cutting the steak before cooking can be beneficial for certain dishes, such as stir-fries, where you need the meat to cook quickly and evenly. When the steak is sliced thinly before it hits the pan, it cooks faster and absorbs more flavor from the marinade or sauce. However, pre-slicing also means that the steak may lose more moisture during cooking, which can make it less juicy.
Cutting After Cooking
For most recipes, especially grilling or broiling, cutting the steak after it has been cooked is the preferred method. Allowing the steak to cook whole helps retain its juices, and slicing it after it has rested guarantees that the meat stays moist. After resting, the steak can be sliced thinly against the grain to achieve the best texture and flavor.
Marination also plays a role in whether you should slice the steak before or after cooking. For whole cuts, marinating the entire steak allows the flavors to penetrate the surface. If you pre-slice the steak, it will absorb more of the marinade but may dry out faster during cooking.
8. Flank Steak Cutting Mistakes to Avoid
When cutting flank steak, there are a few common mistakes that can ruin the texture and flavor of the meat. Avoiding these errors will help make sure that your steak is tender and enjoyable to eat.
Mistake 1: Cutting with the Grain
As mentioned earlier, one of the most common mistakes is cutting with the grain instead of against it. Cutting with the grain leaves the muscle fibers long and intact, which makes the steak tough and chewy. Always take the time to identify the direction of the grain and slice perpendicular to it.
Mistake 2: Using a Dull or Serrated Knife
A dull knife can tear the meat rather than slice through it cleanly, which not only affects the appearance of the steak but also its texture. Similarly, using a serrated knife can leave jagged edges and shred the meat rather than giving you smooth, clean cuts. Always use a sharp, non-serrated knife for the best results.
Mistake 3: Not Letting the Steak Rest
Cutting into the steak too soon after cooking is another mistake that can cause the meat to lose its juices. If you don’t allow the steak to rest, the juices will spill out as soon as you cut into it, leaving the steak dry. Always let the steak rest for at least 10 minutes before slicing to retain its moisture and flavor.
By avoiding these common mistakes, you can make sure that your flank steak is perfectly sliced and full of flavor.
9. Recipes That Benefit from Proper Flank Steak Slicing
How you slice flank steak can greatly impact the final result of your dish. Here are a few recipes where proper slicing is essential for achieving the best texture and flavor:
Flank Steak Fajitas
Fajitas are one of the most popular dishes made with flank steak. For this dish, it’s important to slice the steak thinly against the grain to make sure that the meat is tender and easy to eat. The thin slices also allow the steak to soak up the flavors of the marinade and cook quickly on the grill or in a hot skillet.
- Tip: For fajitas, aim for slices that are about 1/4 inch thick. Thicker slices can make the fajitas harder to eat, while thinner slices may overcook too quickly.
Grilled Flank Steak with Chimichurri
For grilled flank steak with chimichurri, slicing the steak thinly after grilling helps it absorb the sauce and guarantees each bite is full of flavor. Because chimichurri is a bright, herbaceous sauce, it pairs well with the robust flavor of flank steak, and thin slices allow the sauce to coat the meat evenly.
- Tip: For this recipe, slice the steak as thin as possible without shredding it, and be sure to slice against the grain for maximum tenderness.
Flank Steak Stir-Fry
When making stir-fry, slicing the steak before cooking allows it to cook quickly and evenly in the hot pan. Thin, even slices guarantee that the steak doesn’t overcook and become tough. For stir-fry, you’ll want to slice the steak into thin strips, about 1/4 inch wide, to match the size of the vegetables and other ingredients.
- Tip: If you’re slicing the steak before cooking for stir-fry, make sure your knife is sharp, and slice the steak thinly against the grain to retain tenderness during the fast cooking process.
