What is Flank Steak?
Flank steak is a cut of beef taken from the belly area of a cow. It might not be the most tender cut, but its rich, beefy flavor more than makes up for it. When cooked right, flank steak can be incredibly tender, especially when marinated and sliced against the grain. It’s perfect for grilling or broiling and is a fantastic option for barbecues or quick meals.
Originally popularized for its affordability, flank steak has become a beloved choice for many barbecue enthusiasts. And why not? It’s versatile and quick to cook. After all, life is too short for tough steak, right?
Why This Recipe Works
After years of flipping steaks on the grill, I’ve honed this flank steak recipe into something truly special. Here are four reasons why this recipe is a must-try:
1. Flavor Explosion
The marinade is packed with garlic, Dijon mustard, and fresh herbs, creating a flavor profile that elevates the meat. Each ingredient plays its part in enhancing the steak’s natural taste, ensuring every bite is bursting with deliciousness.
2. Perfectly Tender
Cooking flank steak to medium-rare ensures it remains juicy and tender. The key lies in not overcooking, which can turn this flavorful cut into leather. Trust me, no one wants to chew on that!

Prep time is minimal, and cooking takes just a few minutes on the grill. It’s easy to whip up for weeknight dinners or unexpected guests.
4. Versatile Pairing Options
You can serve flank steak with a variety of sides—stuffed potatoes, fresh salads, or even a zesty Italian pasta salad. The choices are endless, making this dish a true star at any table.
Ingredients You’ll Need To Make This Flank Steak
To create this mouthwatering flank steak, gather the following ingredients:
- 1 ½ pounds of flank steak, trimmed
- 3 tablespoons unsalted butter, softened (more if desired)
- 1 teaspoon fresh rosemary, finely chopped
- 2 cloves garlic, finely minced
- Freshly cracked black pepper
- Sea salt, to taste
- 2 teaspoons Dijon mustard

How To Make This Flank Steak
Now let’s get started on this culinary creation! The steps are simple and straightforward.
Step 1: Marinate the Flank Steak
In a large bowl, combine minced garlic, Dijon mustard, rosemary, and softened butter. Mix them until you have a somewhat smooth paste. Rub this mixture all over the flank steak, making sure to cover every inch. Season generously with sea salt and freshly cracked black pepper. This is where the magic begins!
Step 2: Let It Rest
Cover the steak in plastic wrap and refrigerate. Let it marinate for at least one hour. For even more flavor, consider letting it rest overnight. This is a great time to sip a glass of your favorite wine and dream about the delicious meal ahead.
Step 3: Preheat the Grill
Get your grill fired up! Preheat it to medium-high heat. You want that grill to be hot, sizzling, and ready to impress.
Step 4: Grill the Steak
Once the grill is ready, place the flank steak on the grates. Close the lid. Grill for about 4-6 minutes on each side, depending on your ideal doneness. Keep an eye on it. You want a nice caramelized crust on the outside while keeping the inside juicy.
Step 5: Let It Rest Again
Once cooked, remove the steak from the grill. Let it rest for about 10 minutes. This step is crucial. It allows the juices to redistribute, ensuring you enjoy a tender slice every time.
Step 6: Slice and Serve
After resting, slice the steak thinly, against the grain. Serve it with your favorite sides, and enjoy!
Tips for the Perfect Flank Steak
Here are five helpful tips to ensure your flank steak comes out perfect every time:
- Choose the Right Cut: Look for flank steaks that are bright red with minimal visible fat. This indicates freshness and quality.
- Marinate Wisely: Do not skip the marination step. If time allows, longer marination leads to deeper flavors.
- Temperature Check: Use a meat thermometer to check for doneness. Medium-rare is between 130°F to 135°F.
- Resting Is Key: Always let the steak rest before slicing. This is not a step you want to rush.
- Cut Like a Pro: Slice against the grain to ensure tenderness in every bite.

How to Store The Leftovers
If you’re lucky enough to have leftovers, allow the steak to cool completely. Wrap it tightly in plastic wrap or aluminum foil and store it in the refrigerator. It should keep for up to 4 days. For longer storage, consider freezing slices in an airtight container. They can last for up to 3 months. Just let them thaw overnight in the refrigerator before using.
Recommended Side Dishes for Flank Steak
When serving flank steak, sides can make a significant difference. Here are four favorites:
1. Grilled Vegetables
A mix of zucchini, bell peppers, and asparagus drizzled with olive oil and grilled until tender. The smoky flavor pairs perfectly with steak.
2. Creamy Potato Salad
Creamy, tangy, and topped with crunchy bits of celery and onion—this classic is a crowd-pleaser. Each scoop complements beef nicely.
3. Zesty Italian Pasta Salad
Tossed with bursts of colorful veggies and a homemade dressing, this pasta salad adds brightness to your plate. It’s refreshing alongside hearty meat.
4. Garlic Mashed Potatoes
Whipped until velvety smooth and loaded with garlic, these potatoes soak up any juices from the steak. Can’t go wrong here!
Substitute Options for Ingredients
Not all ingredients might be at your fingertips. Here are viable substitutes for the marinade if you’re missing something:
1. Flank Steak Substitute
If you can’t find flank steak, consider using skirt steak or sirloin. Both cuts offer a similar flavor profile.
2. Dijon Mustard Alternatives
In a pinch, yellow mustard or honey mustard can replace Dijon. Just note that they will slightly alter the flavor.
3. Fresh Rosemary Option
If rosemary isn’t handy, thyme or oregano can offer great alternatives. Fresh herbs work best, but dried will work too.
4. Butter Substitution
Coconut oil or olive oil can replace butter, especially if you’re looking for a dairy-free option. The flavors will differ a bit, but it’ll still taste delightful.

Conclusion
Flank steak is a versatile, flavorful cut that can elevate any meal. With a few simple ingredients and some handy tips, you can create a delicious main course that delights everyone at the table. Plus, the ability to pair it with a variety of sides only adds to its charm. So, fire up that grill, invite some friends over, and enjoy a delightful culinary experience. Happy grilling!
