Last night I did a solid frozen prime sirloin from Costco.
Hockey puck solid. It was about 1.25 - 1.5 “ thick. I put the sirloin 100% frozen on the TRAEGER for about 90 minutes at 200 degrees. Zero seasoning, zero thawing and zero oil on the steak. It still had the white ice coat on it. I had Lumberjack Oak in the hopper and pellet tube.
I pulled the steak at 115 degrees internal temperature and THEN SEASONED it with a little olive oil, SPG and O (salt pepper garlic onion) I mix my own. I said 90 minutes above however , I NEVER cook by time but I always keep track of time. I split whatever my salt portion/ content/ % equally with Diamond Crystal Kosher and Lawreys season salt. 16 mesh black pepper.
I let that sit on the steak until I heat my pan up.
PRO TIP # 1 ALWAYS heat your cast iron pan up FIRST for about 10-15 minutes THEN add oil/ butter/ both. It prevents scorching the butter or oil.
PRO TIP # 2. If you add a little oil such as high heat olive oil to your butter it will increase the smoke point of your butter. Or add a little butter to your olive oil for another layer of flavor…. The oil will prevent the butter from smoking within a reasonable temp setting on your stovetop.
I finished it in a cast iron pan with olive oil, a little butter, fresh garlic and onions.
Conduction cooktop for me. Your approx time to temp will vary. I never cook by time. I always keep track of time but I never use it as my guide. I use my Thermapen One to monitor. Could use a Meater here but I chose not to.
Flipped after about 5 minutes on med low heat. About another 5 on the other side until internal temp read 128. Rested under oil for 15 minutes.
My conduction cooktop goes from 1-9 and I pan sear my steak on the 4 setting for a reference.
RESULTS
I will NEVER THAW my steaks again. I might actually freeze my steaks prior to cooking them as long as they are Prime Grade I believe the frozen steak slows the cook down to where the fat could FULLY RENDER. Not sure how a Select or Choice Grade would work.
Heck, the frozen steak might be a Traeger Sous Vide
