Ingredients You'll Need

These ingredients are simple, yet each one plays an essential role in building the perfect pan-seared flank steak. Together, they balance the flavors and textures beautifully without overwhelming the beef’s natural richness.

• Flank steak (1½ pounds): This lean cut is full of flavor and perfect for quick searing.
• Kosher salt: Essential for seasoning and bringing out the steak’s natural juices.
• Freshly ground black pepper: Adds a spicy punch and depth to the flavor.
• Dry mustard: A subtle kick that enhances the meat’s savoriness without overpowering.
• Softened butter (3 tbsp, divided): Adds richness and helps create a luscious crust.

Directions

Step 1: Take your flank steak out of the fridge at least 30 minutes before cooking to let it come to room temperature. This helps the steak cook evenly. While you wait, trim off any tough connective tissue to ensure tender bites.

Step 2: Using a sharp knife, score the steak with shallow cuts about 1 inch apart and roughly ⅛ inch deep. Make these cuts on one side, then flip the steak and repeat on the other side, making sure the cuts remain parallel. This technique helps the seasonings penetrate deeply and encourages even cooking.

Step 3: Pat the steak dry with paper towels to get rid of any moisture, which is key for a good sear. Rub kosher salt, freshly ground black pepper, and dry mustard over both sides in generous but even layers. Then take about a tablespoon of softened butter and work it into the scored cuts—this adds incredible flavor where the heat will hit most directly.

Step 4: Heat a heavy skillet, like cast iron, over high heat until it’s very hot. Place the steak in the pan and let it cook without moving for 4 to 5 minutes. Flip it carefully and cook the other side for 3 to 5 minutes more. You’re aiming for a beautiful browned crust and an internal temperature of about 125°F for medium rare—the thickest part of the steak should reach this temperature.

Step 5: Remove the steak from the heat and immediately top it with the remaining softened butter. Let it rest for 10 minutes; this step is crucial as it allows the juices to redistribute, guaranteeing juicy, tender slices.

Step 6: Slice the steak thinly against the grain. This cutting method breaks down the fibers for maximum tenderness. Don’t forget to spoon any juices left on the cutting board over the slices for extra moisture and flavor.

Servings and Timing

This Pan-Seared Flank Steak Recipe serves 4 generously, making it perfect for family dinners or small gatherings. The prep time is about 10 minutes, with the steak resting for 30 minutes total (including coming to room temperature and resting after cooking). The cook time is roughly 8 to 10 minutes, so the total time you’ll need is about 40 minutes from start to finish. The short cooking time and minimal active preparation make it a super efficient meal without compromising on flavor.

How to Serve This Pan-Seared Flank Steak Recipe

I love serving this pan-seared flank steak with simple, fresh sides that complement its rich flavor. Roasted vegetables, like asparagus or Brussels sprouts, are a natural pairing. Crispy potatoes—whether mashed, roasted, or even a creamy gratin—add a comforting touch that balances the steak perfectly. For a lighter option, a crisp arugula and cherry tomato salad with a lemon vinaigrette adds brightness and contrast.

Presentation makes all the difference when you’re serving guests or wanting to turn an ordinary dinner into something special. I usually arrange the sliced steak fanned out on a warm platter and spoon the flavorful pan juices over the top. A sprinkle of flaky sea salt or fresh herbs like rosemary or thyme can elevate the look and flavor. It’s a simple way to make the meal feel more celebratory.

As for drinks, I’m a fan of pairing this with a full-bodied red wine such as Malbec or Cabernet Sauvignon, which can stand up to the steak’s bold flavors. If you prefer cocktails, a classic Old Fashioned or a smoky mezcal-based drink works beautifully. For non-alcoholic options, a sparkling water with a splash of lime or a robust iced tea provides a refreshing balance.

Variations

If you want to experiment with this Pan-Seared Flank Steak Recipe, there are plenty of ways to make it your own. For example, swapping dry mustard with smoked paprika introduces a warm, smoky tone that pairs beautifully with the seared crust. You could also try adding garlic powder or fresh chopped herbs to the seasoning for more aromatic layers.

For those following specialized diets, flank steak is naturally gluten-free and low-carb, which is wonderful. To make this vegan or vegetarian, though, you might want to explore plant-based steak alternatives and similar seasoning techniques to capture a comparable flavor profile. Another great swap is using ghee or a high-heat oil instead of butter if you need a dairy-free version.

If you’re short on time, grilling the steak instead of pan-searing brings out a smoky, charred flavor with less fuss. Conversely, slow-cooking flank steak with marinade can give you an ultra-tender, fall-apart result, but you lose that signature quick sear crust. My personal favorite remains this pan-seared method for its perfect balance of speed and flavor.

Storage and Reheating

Storing Leftovers

When storing leftover pan-seared flank steak, I recommend placing the slices in an airtight container to preserve moisture and flavor. Keep it refrigerated and try to consume within 3 to 4 days for the best taste and texture. Avoid stacking slices too thickly to prevent them from becoming soggy.

Freezing

You can freeze leftover flank steak if you want to keep it longer. I slice the steak first, then arrange the slices in a single layer on a parchment-lined tray and freeze until firm. After that, I transfer them to a freezer-safe bag or container to prevent freezer burn. Properly stored, frozen steak will keep well for up to 2 months. When ready to use, thaw in the refrigerator overnight.

Reheating

The key to reheating this steak is to do it gently to avoid drying it out. I prefer reheating slices in a skillet over low heat, adding a splash of broth or water and covering the pan briefly to steam and re-moisten the meat. Microwaving can work in a pinch, but be sure to keep it brief and use a lower power setting. Avoid reheating to the point the steak is piping hot throughout as it can become tough. Just warm enough to enjoy as if freshly cooked.

FAQs

What is the best way to get a perfect crust on flank steak?

The best way is to dry the steak thoroughly before seasoning and cook it in a very hot pan without moving it too soon. This allows a caramelized crust to form naturally. Using a heavy skillet like cast iron traps and distributes heat evenly, which is key to that beautiful sear.

How do I know when flank steak is cooked to medium rare?

Using a meat thermometer is your best bet. For medium rare, aim for an internal temperature of 125°F. The steak will continue to cook slightly while resting, so taking it off the heat a few degrees earlier is perfect for juicy, tender results.

Why do you score the flank steak before cooking?

Scoring the steak helps the seasoning penetrate deeper into the meat, enhancing flavor. It also encourages even cooking and helps the butter and other seasonings absorb into the crevices, resulting in richer taste and texture.

Can I use other cuts of beef for this recipe?

You can, but flank steak’s thin, fibrous texture and distinctive flavor lend themselves best to this recipe and cooking method. Skirt steak and hanger steak are good alternatives, but thicker cuts like ribeye or strip steak require different cooking times and techniques.

Is it necessary to let the steak rest after cooking?

Absolutely. Resting lets the juices redistribute throughout the meat, making every slice juicy and tender rather than dry. Ten minutes is ideal—long enough to soak in the butter and finish cooking gently off the heat.

Conclusion

I hope you’ll give this Pan-Seared Flank Steak Recipe a try soon. It’s one of those dishes that feels special without being complicated, and each bite reminds me why I keep coming back to it. Whether it’s a weeknight dinner or a weekend feast, this steak delivers bold flavor, beautiful texture, and a satisfying experience you’ll want to share with loved ones.
