Flank Steak With Garlic Butter: A Chef’s Simple Indulgence

The first time I tasted flank steak with garlic butter, I was a young line cook, overwhelmed by the sheer volume of orders flooding the kitchen. Our head chef, a gruff but secretly kind soul named Marco, noticed my frazzled state and quietly slid a small plate across the counter. On it were a few beautifully sliced pieces of flank steak, glistening with a rich, fragrant garlic butter. The simplicity of the dish, the tender meat, and the explosively flavorful sauce were a revelation. It was a moment of pure culinary comfort that cut through the chaos, a reminder that sometimes the most satisfying flavors are the simplest to achieve. I’ve been making it ever since, adapting it in my own kitchens, but always returning to the essence of Marco’s comforting classic.

Recipe Overview

Prep Time: 5 minutes
Cook Time: 8-10 minutes
Total Time: 13-15 minutes
Servings: 4
Dietary Type: Gluten-Free (naturally)

Ingredients

1 1/2 lbs flank steak
1/2 teaspoon salt
1/4 teaspoon ground black pepper

For the Sauce:

4 tablespoons (1/2 stick) butter
2 garlic cloves, minced
1 pinch ground black pepper
1/2 teaspoon Worcestershire sauce

Equipment Needed

Broiler
Small saucepan

Instructions

Preheat your broiler. Position an oven rack so the top of the flank steak will be about 6 inches from the heating element.
Season the flank steak generously on both sides with salt and ground black pepper. Don’t be shy with the seasoning – this is crucial for developing a flavorful crust.
Place the seasoned steak on a broiler-safe pan (a sheet pan lined with foil for easier cleanup works well).
Broil the flank steak for approximately 8 to 10 minutes, flipping it halfway through. The exact cooking time will depend on the thickness of your steak and your desired level of doneness. For medium-rare, aim for an internal temperature of 130-135°F (54-57°C) when checked with a meat thermometer. Remember to flip the steak once halfway through the cooking process to ensure even cooking on both sides.
While the steak is broiling, prepare the garlic butter sauce. In a small saucepan over medium heat, melt the butter.
Once the butter is melted, add the minced garlic, a pinch of ground black pepper, and the Worcestershire sauce to the saucepan. Stir constantly and cook for about 1 minute, or until the garlic is fragrant but not browned. Burnt garlic will make the sauce bitter.
Remove the steak from the broiler and let it rest for 5-10 minutes before slicing. This allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful steak.
While the steak is resting, if there are any accumulated steak juices on the pan, carefully pour them into the garlic butter sauce. These juices add an extra layer of savory flavor to the sauce.
To serve, slice the flank steak thinly against the grain. This is crucial for maximizing tenderness, as the long muscle fibers of the flank steak can be tough if cut the wrong way. Cutting against the grain shortens these fibers, making the steak much easier to chew.
Drizzle the garlic butter sauce generously over the sliced steak. Serve immediately.

Expert Tips & Tricks

Reverse Sear: For an even more tender and flavorful steak, consider the reverse sear method. Cook the steak in a low oven (around 250°F/120°C) until it reaches your desired internal temperature, then sear it in a hot pan or under the broiler for a beautiful crust.
Marinating: While this recipe is delicious in its simplicity, you can also marinate the flank steak for added flavor. A simple marinade of olive oil, balsamic vinegar, garlic, and herbs works wonderfully. Marinate for at least 30 minutes, or up to overnight in the refrigerator.
Don’t Overcook: Flank steak is best served medium-rare to medium. Overcooking will make it tough and dry. Use a meat thermometer to ensure accurate doneness.
Garlic Intensity: Adjust the amount of garlic to your preference. For a milder garlic flavor, use just one clove or add it later in the cooking process. For a bolder flavor, use more garlic and cook it for a shorter amount of time.

Serving & Storage Suggestions

Serve the sliced flank steak with garlic butter immediately while it’s hot and the sauce is glistening. It pairs beautifully with a variety of sides, such as roasted vegetables (asparagus, broccoli, or Brussels sprouts are excellent choices), mashed potatoes, a simple green salad, or even grilled corn on the cob.

Leftover flank steak can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over low heat or in a microwave. The garlic butter sauce may solidify in the refrigerator; simply reheat it gently in a saucepan or microwave until melted. Sliced flank steak can also be frozen for up to 2 months. Wrap it tightly in plastic wrap and then place it in a freezer-safe bag or container. Thaw overnight in the refrigerator before reheating.

Variations & Substitutions

Spicy Kick: Add a pinch of red pepper flakes to the garlic butter sauce for a touch of heat.
Herbaceous Twist: Stir in some fresh chopped herbs, such as parsley, thyme, or rosemary, to the garlic butter sauce for added flavor and freshness.
Lemon Zest: A little lemon zest brightens up the sauce beautifully. Add it at the very end for the best flavor.
Balsamic Glaze: Drizzle a balsamic glaze over the sliced steak for a touch of sweetness and acidity.
Wine Reduction: Deglaze the pan with a splash of red wine after cooking the garlic and reduce slightly before adding the Worcestershire sauce and steak juices for a deeper, richer sauce.

FAQs (Frequently Asked Questions)

Q: How do I know when the flank steak is cooked to medium-rare?
A: The best way is to use a meat thermometer. Insert it into the thickest part of the steak; medium-rare is 130-135°F (54-57°C).

Q: Can I use a different cut of steak for this recipe?
A: While flank steak is ideal, skirt steak or hanger steak can also be used as alternatives. Cooking times may vary slightly.

Q: What if I don’t have Worcestershire sauce?
A: A small amount of soy sauce or even a dash of balsamic vinegar can be used as a substitute, though the flavor won’t be exactly the same.

Q: Can I make the garlic butter sauce ahead of time?
A: Yes, you can. Prepare the sauce and store it in an airtight container in the refrigerator for up to 3 days. Reheat gently before serving.

Q: Why is it important to slice the steak against the grain?
A: Flank steak has long muscle fibers. Slicing against the grain shortens these fibers, making the steak much more tender and easier to chew.
