Choosing the Right Cut
The quality of your steak is the foundation of a great meal. When shopping:

Olive oil | 1/4 cup |
Soy sauce | 1/4 cup |
Garlic (minced) | 3 cloves |

How to Grill Flap Steak on a Gas Grill
Setting Up the Gas Grill
Preparation is key to a successful grilling experience. Follow these steps to get started:
- Preheat the Grill: Set your gas grill to medium-high heat (about 400-450°F).
- Clean the Grates: Use a grill brush to remove any residue, ensuring your steak won’t stick.
- Oil the Grates: Dip a folded paper towel in vegetable oil, then use tongs to rub it over the grates for a non-stick surface.
Grilling Steps
- Prepare the Steak: Remove the steak from the marinade and pat it dry with paper towels. Season lightly with salt and pepper if needed.
- Searing:
- Place the steak on the grill’s hottest area.
- Sear for 2-3 minutes per side to develop a golden-brown crust.
- Indirect Heat:
- Move the steak to a cooler area of the grill.
- Cook until the internal temperature reaches your desired doneness:
- Rare: 120-125°F
- Medium-rare: 130-135°F
- Medium: 140-145°F
- Resting:
- Remove the steak from the grill and let it rest for 5-10 minutes.
- Resting allows the juices to redistribute, resulting in a tender and flavorful steak.

Slicing and Serving
- Use a sharp knife to slice the steak thinly against the grain.
- Serve with your favorite sides, such as roasted vegetables, mashed potatoes, or chimichurri sauce for an added burst of flavor.
Troubleshooting Common Issues
Even seasoned grillers can encounter challenges. Here are some tips to help you overcome common pitfalls:
- Overcooked Steak: Use a meat thermometer to avoid guessing doneness.
- Sticking to Grill: Ensure your grill grates are well-oiled and preheated before cooking.
- Tough Meat: Always slice against the grain to break down the muscle fibers and enhance tenderness.
