Sirloin Steak – What You Should Know
Sirloin steaks are a lean and quality meat with a thick fat cap. Some might consider the sirloin less flavorful than a rib-eye and not as tender as a filet mignon.

Why You’ll Love Cooking Sirloin Steak on a Traeger
I think this one of my favorite ways to cook steak. You get a light smoky flavor but still get the hallmarks of a traditionally grilled steak with it grill marks and char. Plus you don’t have to flip your steak if you don’t want to as the steak are cooking with indirect heat. If you want to flip your steak you can though.
I also love cooking sirloin on my Traeger because its easy to monitor the internal temperature with the built-in probes.


How Are We Cooking the Sirloin in the Traeger?
Grilling with high and direct heat produced from the wooden pellets of course!

The Benefits of Grilling a Sirloin Steak on a Traeger

- Helps to renders the fat content down without drying out the piece of steak.

What Temperature to Cook Beef Sirloin on a Traeger?

How Long to Cook Beef Sirloin on a Traeger?
At 300°F a 1-inch thick medium steak will take around 15 minutes.
Note: Read further for the exact internal temperatures for level of doneness.

What Internal Temperature Does Sirloin Steak Need to Be?
Below are the internal temperatures for each level of doneness.
I suggest you cook a sirloin steak to an even medium.
This way the fat has had enough time to render but the lean muscle won’t dry out!
Internal Temperatures for the Level of Doness
Rare – 125°F on a meat thermomoeter.
Medium – 135°F on a meat thermometer.
Well done – 155°F on a meat thermometer

How to Accurately Monitor the Internal Temp
A calibrated meat probe will surely be in your cooking arsenal now!
Plate up any meal easily while knowing your food is safe.
Have a calibrated and reliable meat thermometer in the thickest part of your steak.
Monitor until cooked to perfection!

Choosing the Right Wood Pellets for the Sirloin
We are cooking the sirloin for a short amount of time and on high heat.
So the type of wood for flavor isn’t required as much as it would be a brisket or turkey.

Maple burns hot and has a nice mild flavor.
Perfect to cook and enhance the sirloin steak taste.

What if I Don’t Have a Traeger Pellet Smoker?
A traditional charcoal grill will work well for maximum flavor.
A cast-iron skillet is another alternative, with plenty of butter and garlic!

Do I Need to Rest the Sirloin Steak?
You should always rest your meat no matter what!
A thin piece of beef won’t need long but it makes all the difference.
Allowing the juices to be reabsorbed back into the meat proteins.

– Wrap in aluminum foil for 10 minutes.
– Monitor the internal temp to make sure it doesn’t go over your required doneness.
