To grill flank steak on a gas grill, preheat your grill to high (450-500°F), then sear each side for 2-3 minutes before reducing heat to medium-low and cooking to your desired internal temperature, typically 125-135°F for medium-rare.
Always rest the steak for 5-10 minutes off the heat, tented with foil, allowing juices to redistribute before slicing thinly against the grain for maximum tenderness.
TL;DR: Grilling Flank Steak on a Gas Grill Made Easy
- Choose a good flank steak, then marinate for at least 30 minutes, or up to 12 hours.
- Preheat your gas grill to a scorching 450-500°F for that perfect sear.
- Sear each side for 2-3 minutes, then cook indirectly or over lower heat to your preferred doneness.
- Use a meat thermometer to ensure accuracy – 125-135°F for delicious medium-rare.
- Rest your steak well before slicing it thinly against the grain for peak tenderness.
How To Grill Flank Steak Gas Grill?
Grilling flank steak on a gas grill is simple when you know the steps. You’ll want to aim for a high heat sear followed by careful cooking to reach your perfect doneness.
Picking Your Perfect Flank Steak
The journey to a great grilled flank steak begins at the butcher. Look for a steak with a deep red color and minimal connective tissue.
Many experts say to choose a piece that is about 1 to 1.5 inches thick for the best grilling results.
A good flank steak will cook evenly and absorb marinades wonderfully. Don’t shy away from asking your butcher for help.
Why Marinate Flank Steak?
Flank steak can be a bit lean, which means it benefits greatly from a marinade. A marinade adds flavor and can help tenderize the meat. Think of it as giving your steak a spa treatment!
We found that marinades containing acidic ingredients, like vinegar or citrus juice, help break down muscle fibers slightly. This process makes for a more tender bite (USDA Food Safety and Inspection Service).
Essential Marinade Ingredients
What goes into a great marinade? You’ll want a mix of acid, oil, and seasonings. Here’s a simple combination to get you started:
- Soy sauce (for umami and salt)
- Olive oil (to carry flavors and prevent sticking)
- Minced garlic (always a flavor booster)
- Fresh lime juice or red wine vinegar (for tenderizing)
- A touch of brown sugar or honey (for caramelization)
- Black pepper and other herbs you enjoy
Combine these in a bag with your flank steak. Allow it to marinate in the refrigerator for at least 30 minutes. You can even go up to 12 hours for deeper flavor.
Prepping Your Gas Grill for Flank Steak
Getting your grill ready is half the battle. You want a clean, hot surface for that beautiful sear.
First, scrape off any old food bits from the grates. Then, preheat your grill with all burners on high. Aim for a grill temperature of 450-500°F.
A hot grill ensures a quick crust forms, locking in juices. This is a critical step for a juicy, flavorful steak.
Grilling Flank Steak: The Technique
Now for the main event! Grilling flank steak is about direct heat and careful timing. It cooks quickly.
Searing the Steak
Place your marinated flank steak directly over the high heat. Close the lid for better heat retention.
Sear the first side for 2-3 minutes until you see a nice brown crust. Flip it over and sear the second side for another 2-3 minutes. This creates a fantastic texture and flavor on the outside.
Finishing to Perfection
After searing, reduce the heat to medium-low, or move the steak to a cooler part of the grill. You’ll cook it here until it reaches your desired internal temperature.
Many grill enthusiasts aim for medium-rare, which is around 125-135°F. Remember, the steak will continue to cook a bit after you remove it from the grill (carryover cooking).
Using a reliable instant-read meat thermometer is your best friend here. Don’t guess!
| Doneness | Internal Temp (°F) | Approx. Total Grill Time (1-1.5″ thick) |
|---|---|---|
| Rare | 120-125°F | 8-10 minutes |
| Medium-Rare | 125-135°F | 10-12 minutes |
| Medium | 135-140°F | 12-14 minutes |
| Medium-Well | 140-145°F | 14-16 minutes |
These times are approximate; always rely on your thermometer for accuracy.
The All-Important Rest
This step is non-negotiable! Once your flank steak hits the target temperature, remove it from the grill.
Place it on a cutting board and tent it loosely with foil. Let it rest for 5-10 minutes. Why? This allows the juices, which have gathered at the center, to redistribute throughout the meat.
Cutting too soon would cause all those delicious juices to run out. You would end up with a drier steak. Resting ensures a tender and juicy outcome.
Slicing Against the Grain
Once rested, it’s time to slice. Flank steak has a very visible grain running through it. This refers to the direction of the muscle fibers.
Always slice against the grain, meaning perpendicular to the direction of those fibers. Slicing with the grain will give you tough, chewy pieces.
Thin slices, cut against the grain, are key to maximizing tenderness. This makes it much easier to chew and enjoy.
Quick Checklist for Grilling Flank Steak
Before you fire up the grill, here’s a quick mental run-through:
- Flank steak purchased and ready?
- Marinade made and steak soaking?
- Gas grill clean and preheating?
- Instant-read thermometer at hand?
- Cutting board and foil ready for resting?
- Sharp knife for slicing?
Conclusion
Grilling flank steak on a gas grill is a fantastic way to enjoy a flavorful, versatile cut of meat. By following these straightforward steps—from choosing your steak and marinating it properly, to achieving the perfect sear and crucial resting period—you’ll consistently produce a delicious meal.
Remember, attention to detail, especially with temperature and slicing, transforms a good steak into a truly great one. Go ahead, fire up that grill and enjoy your culinary success!
Frequently Asked Questions About Grilling Flank Steak
Can I grill flank steak without marinating it?
Yes, you can grill flank steak without a marinade. However, many find that a marinade significantly improves its tenderness and adds a lot of flavor. If you skip the marinade, consider seasoning generously with salt and pepper right before grilling.
How do I prevent flank steak from drying out on the grill?
To prevent drying, avoid overcooking the steak. Use an instant-read thermometer to pull it off the grill when it reaches your desired internal temperature, typically 5-10 degrees below its final resting temperature. Also, always rest the steak after grilling.
What temperature should my gas grill be for flank steak?
For flank steak, you should preheat your gas grill to a high temperature, around 450-500°F, for searing. After searing each side, reduce the heat or move the steak to a cooler zone to finish cooking.
How do I know when my flank steak is medium-rare?
The most reliable way is to use an instant-read meat thermometer. For medium-rare, aim to remove the flank steak from the grill when it reaches 125-135°F. It will rise a few degrees as it rests.
Is flank steak tough if not sliced correctly?
Absolutely. Flank steak has long muscle fibers, and if you slice it with the grain (parallel to the fibers), it will be very chewy. Always slice it thinly against the grain to break up those fibers, making each bite tender and easy to enjoy.
