Easy Grilled Sirloin Steak on Weber Gas Grills

There’s something undeniably satisfying about a simply seasoned, perfectly grilled piece of beef. In this recipe we’ll walk through how to make a quick, flavorful steak using a Weber gas grill and a handful of straightforward ingredients. The method is approachable for weeknights but impressive enough for weekend cookouts. Expect a caramelized crust, a juicy interior, and a bright, slightly sweet-salty sauce that ties it all together.

Why this recipe works

This recipe is built around a thick 1 lb sirloin steak, roughly 2 inches in thickness. That size and thickness make it ideal for high heat searing on a gas grill while still allowing the center to reach a perfect medium-rare to medium doneness without overcooking. A simple 2 teaspoon BBQ rub layers in smokiness and savory notes, while a small teriyaki-based sauce, a touch of sesame oil, and fresh cilantro and ginger add balance and brightness. The sesame seeds are optional but give a pleasant nutty crunch and an attractive finish.

Equipment

• Weber gas grill (or any reliable gas grill)

Taste profile and variations

The BBQ rub gives depth and a hint of smoke; the teriyaki-style sauce contributes sweet-salty balance; sesame or avocado oil brings a smooth mouthfeel and helps the surface crisp; fresh ginger and cilantro brighten the finished steak.

Step-by-step instructions

Follow these clear, sequential steps to get the best result from your skillet of flavors and Weber gas grill. The directions have been rewritten for clarity while preserving all ingredient quantities and the original order of preparation elements.

1. Bring the steak to room temperature. Remove the 1LB sirloin steak about 2” thick from refrigeration and let it sit on the counter for about 20–30 minutes. This helps the steak cook more evenly on the Weber gas grill.
2. Prepare the sauce. In a small bowl, combine ½ cup teriyaki sauce substitute soy sauce + 1 tbsp brown sugar for sweetness, 2 tbs oil sesame or avocado preferred, and 1 tsp ginger fresh chopped. Stir until the sugar dissolves and the ingredients are well combined. Set this sauce aside for basting and finishing.
3. Season the steak. Pat the steak dry with paper towels. Evenly rub the surface of the steak with 2 tsp bbq rub, pressing the rub into both sides so it adheres. Be sure to coat the edges lightly as well.
4. Preheat the Weber gas grill. Turn on your Weber gas grill and set it to high heat. Allow the grill to preheat for about 10–12 minutes with the lid closed until the grates are very hot. A well-heated grill gives you a better sear.
5. Oil the grates or the steak. Lightly brush the grill grates with oil or brush the steak with the remaining oil from the sauce if needed. This helps prevent sticking and encourages a golden crust.
6. Sear the steak. Place the steak directly over the hottest part of the grill. Sear for 3–4 minutes without moving it, so a deep crust forms. Use tongs to flip the steak and sear the opposite side for another 3–4 minutes. The exact time depends on your grill and desired doneness.
7. Check the internal temperature. Insert a meat thermometer into the thickest part of the steak. For medium-rare aim for 125–130°F, for medium 135–140°F. If the steak needs more time after searing, move it to a cooler part of the grill and close the lid, monitoring the temperature until it reaches your target.
8. Baste and finish. In the last 1–2 minutes of cooking, brush the top of the steak with a few spoonfuls of the prepared sauce to add glaze and extra flavor. If you like a stronger char, let it glaze briefly over direct heat; for a gentler finish, glaze while the steak rests.
9. Rest the steak. Transfer the steak to a cutting board and tent loosely with foil. Rest for 5–10 minutes to allow juices to redistribute. This step is essential for a tender, juicy slice.
10. Slice and garnish. Slice the steak against the grain into even pieces. Sprinkle 1 tbsp sesame seeds optional and 1 tbsp cilantro fresh chopped over the top as a finishing touch. Serve with any remaining sauce on the side.

Serving suggestions

This steak pairs beautifully with simple side dishes that won’t overpower the flavors. Think grilled asparagus or green beans, a crisp cabbage slaw, steamed jasmine rice, or roasted baby potatoes. A quick cucumber salad with rice vinegar and a pinch of sugar also offers a refreshing counterpoint to the savory meat.

Timing and doneness guide

• Preheat grill: 10–12 minutes
• Sear both sides: 6–8 minutes total
• Rest: 5–10 minutes

Use a meat thermometer for accuracy. For a 2” thick sirloin: 125–130°F for medium-rare, 135–140°F for medium. Remember that carryover cooking can raise the temperature by a few degrees while the steak rests.

Tips for success on a Weber gas grill

• Always preheat the grill with the lid closed to build consistent high heat.
• Keep a clean, well-oiled grate to prevent sticking and to help achieve a clear sear pattern.
• Resist the urge to flip constantly; allow one solid sear per side first for the best crust.
• Use a thermometer instead of guessing—the visual cues can vary by grill and steak thickness.
• If flare-ups occur from dripping sauce or fat, move the steak to a cooler zone until flames subside, then finish the cooking.

Make-ahead and storage

You can prepare the sauce up to a day ahead and refrigerate it in an airtight container. Cooked steak will keep in the refrigerator for 3–4 days; reheat gently in a low oven or slice thinly and heat in a skillet with a splash of oil to keep it tender. Leftover steak is fantastic in salads, sandwiches, or sliced over rice bowls.

Notes on ingredients and substitutions

• If you don’t have teriyaki sauce, use ½ cup soy sauce plus 1 tbsp brown sugar as the recipe suggests; mix until the sugar dissolves. If you’d like a less salty option, use a reduced-sodium soy sauce and taste before glazing.
• Sesame oil gives a subtle toasted note; use avocado oil if you prefer a neutral flavor for searing and reserve sesame oil for finishing if desired.
• The 2 tsp bbq rub called for here can be any blend you enjoy. If it contains ingredients you’d rather avoid, swap with your preferred commercial rub or a simple mix of smoked paprika, garlic powder, salt, and black pepper in the same amount.
• Ginger fresh chopped adds bright rooty spice. If fresh isn’t available, 1/4 tsp ground ginger can be used but fresh is recommended for a crisp flavor.
