Are Sirloin Steaks Good Smoked?
Yes, with a caveat. Sirloin takes smoke flavor well and reverse searing gives you tight control over doneness, similar to a ribeye. The difference is that sirloin is leaner than ribeye, so while it’s more forgiving in some ways (less risk of flare-ups from rendering fat), it’s less forgiving of overcooking — there’s less fat to keep it juicy if you miss your target temperature. Treat it as a great smoking candidate, not a fattier cut’s equivalent.
Slow Smoked vs. Slow Cooked Sirloin
These are different techniques aimed at different results. Slow smoking, the method in this article, means bringing the steak up to temperature gently in a smoker, then finishing with a hot sear — the goal is a medium-rare steak with a crust. Slow cooking (braising in liquid over hours) is a different approach aimed at breaking down tough cuts like chuck roast into a fall-apart texture, and it’s a poor fit for sirloin since it’s tender enough to grill or smoke as a steak rather than needing to be braised. If you’re picturing a pot roast-style result, that’s not what this method produces — for that, you’d want a braising cut, not a sirloin steak.
What You Need
- Sirloin steak, 1-1.5 inches thick
- Kosher salt and black pepper, or a simple steak rub
- Instant-read thermometer
How to Slow Smoke a Sirloin Steak
Season and Rest
Season generously with salt and pepper (or a rub) and let the steak sit at room temperature for 20-30 minutes, or dry brine it uncovered in the fridge for a few hours beforehand for deeper seasoning.
Smoke at 225-250°F
Set your smoker to 225°F for a slower, more even smoke, or 250°F to shave some time off. Place the steak on the smoker and let it cook gently, checking internal temperature rather than going by time.
Sear to Finish
Once the sirloin reaches about 10-15°F below your target doneness, pull it and sear it hard on a very hot grill or cast-iron pan for 1-2 minutes per side to build a crust.
Rest Before Slicing
Rest for 5-10 minutes before slicing, so the juices redistribute instead of running out.
Timing on a Pellet Smoker
On a pellet smoker held at 250°F, a 1-1.5 inch sirloin typically takes about 45-75 minutes to reach pull temperature, depending on thickness and how consistently your smoker holds temperature — pellet smokers are generally steady, so this is a reasonably reliable range, but always confirm with a thermometer rather than trusting the clock alone.
Sirloin Doneness Temps
| Doneness | Pull Off Smoker | Final After Sear + Rest |
|---|---|---|
| Rare | 105-110°F | 120-125°F |
| Medium-Rare | 115-120°F | 130-135°F |
| Medium | 125-130°F | 140-145°F |
Because sirloin is leaner than ribeye or tenderloin, avoid pushing it past medium — it dries out noticeably faster once past that point. For a similarly lean, reverse-seared cut with more detail on timing by weight, see our smoked beef tenderloin guide.
FAQ
How long to smoke sirloin steak at 250 degrees? About 45-75 minutes for a 1-1.5 inch steak, depending on thickness — pull 10-15°F below your target and confirm with a thermometer.
Are sirloin steaks good smoked? Yes — it takes smoke flavor well and reverse searing gives good doneness control, though it’s leaner than ribeye so it’s less forgiving of overcooking.
Can you slow cook beef sirloin steak? Slow cooking (braising) is really meant for tougher, collagen-rich cuts and isn’t the right technique for a tender sirloin steak — slow smoking with a reverse sear is the better approach for this cut.
How long to cook a sirloin steak on a pellet smoker? Roughly 45-75 minutes at 250°F for a 1-1.5 inch steak to reach pull temperature, then a quick hot sear to finish.
