IMHO totally worth doing. I always reverse sear now. We could never cook steaks before, always had issues with doneness and flavor. Once I got a pellet grill and reverse seared, been no looking back. We did some 1.5"+ thick NY steaks Sat, simply awesome. I might be able to do just high heat sear till done now that I have cooked more steaks. But the slow smoking definitely makes a difference in tenderness and flavor for us, plus the smoke ring as mentioned by DK.
If you do not think you are noticing a difference here is an experiment for you. Put the steaks in your oven at the same temp you smoke at and cook just as if smoking, then do your searing as usual and see what you think. Ultimate true taste test would be to do half smoked, half baked and then have a side by side taste test. Some people just do not pickup the subtle smoke flavor, others do.
You can also try using different woods, and use a 100% pure single flavor wood, 100% hickory, 100% mesquite, etc which can make a more distinct flavor than blends do.
Here is what I do when I reverse sear:
I know some people say you should never flip more than once, I have always flipped numerous times to let the high heat work both sides evenly thru the cook. The times here are what usually work for us, the temp of your grill will have a significant affect on sear time. The last 2 min often gets cut short on my cooks, I am watching temp closely to hit desired temp for my guests. Some like 140, some like more done. The set this weekend spiked in last 2 min and went into upper 150's. They had just a faint glimmer of pink left so overdone a bit by most standards, but very juicey still and super tender.
Pull steaks out of fridge and coat with rub of choice,
Let the steaks sit out with while I set my rectec to 180* xtreme smoke and let it come to temp.
Then on they go and stay in smoke until they reach ~100*IT, I use a tappeque to monitor.
Pull them off, cover with foil while Rectec climbs to max temp.
I have grill grates for searing and On they go for:
- 2min
- then flip
- 2min
- flip and rotate 45-90* to get crossed sear marks.
- 2min
- flip and rotate 45-90* again.
- 2min
DONE! We have tried letting them sit and not. We all prefer them super hot fresh off the grill in my house so they only sit long enough for people to dish up whatever else they are planning to have with dinner.
