Grilling flank steak not only enhances its natural flavor but also allows for a beautiful char that elevates your dish. In this guide, we will break down everything you need to know—from selecting the right steak to grilling techniques and tips that will guarantee mouthwatering results.
While grilling may seem daunting to some, this step-by-step approach will help you gain confidence in your grilling skills. Let’s dive in!
Selecting the Perfect Flank Steak
Choosing the right flank steak is crucial for achieving the best flavor. Flank steak is a lean cut from the abdominal muscles of the cow, making it flavorful but also requiring some attention when cooking.
Look for flank steak that has a bright red color and a decent amount of marbling. Marbling refers to the small streaks of fat within the meat, which enhances flavor and juiciness when cooked. Avoid any cuts with a greyish hue or excessive drainage.
Meat is graded based on several quality factors, including age, tenderness, and flavor. The three primary grades in the U.S. are Prime, Choice, and Select. For grilling flank steak, Choice offers a good balance between flavor and price, making it a popular choice among home cooks.
Preparation is key to a delicious flank steak experience. Aside from marinating, which significantly boosts flavor, keep in mind the following steps.
While some fat is essential for flavor, too much can lead to flare-ups and an unpleasant chew. Trim off any excess fat, but don’t remove it all; a little bit adds to the juiciness.
To ensure the flank steak is as tender as possible, consider knife techniques such as scoring the meat. Make shallow cuts across the grain, which will help break down connective tissue. This makes the steak easier to chew and enhances flavor absorption from any marinades.
Marinating your flank steak brings it to life. Use an acid like vinegar or citrus to tenderize, combined with oil and spices for flavor. Popular marinades include teriyaki, chimichurri, and classic garlic and herbs. For best results, marinate for at least 2 hours, and up to 24 hours if time allows.
Getting your gas grill ready is essential for cooking the perfect flank steak. A well-prepared grill ensures even cooking and prevents sticking.
Before cooking, always clean the grill grates. Use a grill brush to scrub away any residue from previous meals. This will enhance flavor and prevent sticking, allowing for those beautiful grill marks we all love.
Set your gas grill to high heat and preheat for about 10 to 15 minutes. The goal is to attain a temperature of around 450°F to 500°F. An adequately preheated grill will create a nice sear on the outside while keeping the inside juicy.
To prevent sticking, add a bit of oil to the grates. Rub a paper towel soaked in oil across the grill grates using grill tongs. This helps create a non-stick surface and also adds a bit of flavor.
Now that you’ve selected, prepared, and set up your grill, it’s time to cook!
Place the marinated flank steak diagonally across the grates. This will give you those appealing crosshatched grill marks. Close the lid to capture the heat.
Cook the steak for approximately 4 to 6 minutes on the first side. Don’t flip too soon; allow a good sear to form. After flipping, cook for an additional 3 to 5 minutes on the other side for medium-rare, aiming for an internal temperature of about 130°F.
Use a meat thermometer to check the internal temperature. Keep in mind the following temperatures for preference:
| Doneness | Internal Temperature |
|—————|———————|
| Rare | 125°F |
| Medium-Rare | 130°F |
| Medium | 140°F |
| Medium-Well | 150°F |
| Well-Done | 160°F |
For flank steak, medium-rare is often recommended for the best flavor and tenderness.
Once the desired doneness is reached, remove the steak from the grill. It’s crucial to let it rest for at least 5 to 10 minutes before cutting. This allows the juices to redistribute throughout the meat, ensuring a juicy result.
Slicing the flank steak correctly can make all the difference. Flank steak has long muscle fibers that can lead to a tough experience if cut improperly.
To avoid toughness, always slice against the grain. This means cutting perpendicular to the direction of the fibers, which shortens them and makes each bite more tender. Aim for slices around 1/4 inch thick for optimal eating.
Flank steak is delicious on its own, but it pairs excellently with various sides. You can serve it in salads, tacos, or alongside roasted veggies. Consider garnishing with fresh herbs or a squeeze of lime for added flavor and vibrancy.
– Try Different Marinades: Experiment with various marinades to discover your favorite flavor profile.

– Use a Meat Thermometer: This ensures accurate cooking and personal preference for doneness.
– Rest Before Slicing: A critical step to maintaining juiciness and flavor, don’t skip this!
