Run Sheet · No. 3 · Date Night · Smoke, Then Sear
Reverse-seared filet mignon: low smoke on the Deck Boss, then a ripping charcoal sear on the Weber kettle. Two steaks, two targets โ hers medium (filet is her favorite; she outranks everyone), his medium-rare โ and the whole trick is that reverse sear makes cooking two doneness levels easier, not harder: same smoker, two pull temps, one sear. Thermometer runs this cook; the clock just watches.
Both filets from smoker-on to the plate โ about 70 minutes. Crimson is hers (medium), steel is his (med-rare). His comes off the smoker first and waits โ that's not a bug, it's the method: a reverse-seared steak can sit 15 minutes with zero penalty, because the sear re-fires the surface right before serving. Hover for time and temp.
Times count down to dinner (T–0). Total active window is about 90 minutes, but the only precision moments are the two pulls and the sear โ everything else is forgiving.
Dry brine โ salt now, thank yourself later
Pit on 225°F
Filets on, straight from the fridge
Light a full chimney on the Weber
His comes off at 115° โ and waits
Dump the chimney, grate on, let it roar
Hers comes off at 125°
The sear โ 60–90 s per side, both at once
No rest. Plate and serve immediately.
The teach-me-something section. Three pieces of physics, one payoff.
Sear-first blasts the outside while the center catches up, leaving a ring of overcooked gray meat under the crust. Low-and-slow first brings the whole interior up evenly โ then the sear only has to build crust, not cook meat. Result: edge-to-edge pink, crust like a steakhouse.
The Maillard reaction (browning) can't start until surface water boils off โ and searing wet meat wastes your hottest seconds steaming. An hour in the smoker's dry airflow desiccates the surface, so the crust forms in 60 seconds instead of 4 minutes โ which is also why the gray band stays thin.
At 225°F the steak's core climbs about 2° per minute โ you have a 5-minute window to nail a pull temp. Over direct coals it climbs 10°+ per minute; the same window is 30 seconds. Reverse sear moves all the precision to the slow phase, where precision is easy.
Ranked by how much they'd hurt on a cut this expensive.
Will bite you
Under ~1¼ inches there's no thermal "inside" to protect โ the sear cooks the whole thing through. Ask the butcher for center-cut filets, 1½ to 2 inches tall (6–8 oz each). Tall and narrow beats wide and flat.
Charcoal that isn't fully ashed over vents acrid, sooty smoke โ and filet has no fat cap to hide it. Every coal gray before you dump. Light earlier than feels necessary; ready-too-soon coals just wait patiently.
The entire method is a ±5° game. Probe dead-center, and spot-check with the instant-read at the pull and during the sear โ a probe resting near the edge of a small filet reads 10° hot and turns her medium into medium-well.
Butter burns at 350°; the coals are pushing 700°. The sequence is: dry surface → sear → then butter. (The reverse of the glaze rule from the chicken cook โ same principle, different fat.)
Good to know
Tenderloin is the most tender and least fatty cut โ flavor rides on the smoke, the crust, the salt, and a finishing fat. A compound butter (garlic, thyme, cracked pepper) made ahead is the cheapest upgrade in steak.
~2–3° of drift after the smoker pull, ~3–5° after the sear. The pull numbers on this sheet already account for both โ that's why "off at 115" becomes med-rare at 130–135 on the plate.
Party trick with real physics: set a small grate directly on top of the lit chimney and sear there โ the chimney is a jet engine (~1,000°F at the throat), one steak at a time, ~45 s/side. For two filets the kettle pile is more practical, but now you know.
His filet sits at ~113° for ten minutes while hers finishes โ internally it's pasteurized-warm and perfectly happy. The sear reheats the surface and the plate arrives hot. This slack is exactly why reverse sear laughs at scheduling stress.
He just joined her at medium โ or, salvage: shorten his sear to 30–40 s/side and he lands ~135, high med-rare. The lesson for next time is probe placement, not pit temp.
Pull the filets at temp and let them sit loose on a plate โ 15 minutes costs nothing (see: his wait). Never leave them on the smoker "to hold"; that's how 115 becomes 135.
The smoke phase still happens under the Deck Boss lid โ then sear inside in a screaming cast-iron skillet, 60–90 s/side with a butter baste. Different crust, same science, dry pants.
Back on the kettle's cooler edge, 60–90 seconds a side off the direct pile, instant-read to 150. No shame โ the method makes corrections cheap.
