Run Sheet · No. 3 · Date Night · Smoke, Then Sear

Two Filets,
Two Fires

Reverse-seared filet mignon: low smoke on the Deck Boss, then a ripping charcoal sear on the Weber kettle. Two steaks, two targets — hers medium (filet is her favorite; she outranks everyone), his medium-rare — 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.

Smoke at 225°F ~45–60 min

Hers off pit 125° → medium after sear

His off pit 115° → med-rare after sear

Sear 60–90 s per side, full chimney

Rest after None already rested — serve hot

Thickness 1½–2″ thinner can't reverse-sear

The Shape of the Cook

Both filets from smoker-on to the plate — about 70 minutes. Crimson is hers (medium), steel is his (med-rare). His comes off the smoker first and waits — 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.

Hers — medium His — med-rare Temps rule, clocks advise. Probes decide everything.

Timeline

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 — everything else is forgiving.

Morning of or at least 1 hr ahead

MorningT–8 hr ish

Dry brine — salt now, thank yourself later

Pat dry, salt generously on all sides (¾ tsp kosher per pound), onto a rack in the fridge, uncovered.
Two jobs at once: the salt dissolves and seasons deep, and the fridge air dries the surface — and a dry surface is what sears. Even 1 hour helps; morning-of is ideal.
No pepper yet — it scorches over charcoal. It goes on after the smoke.

Cook dinner at T–0

T–1:30

Pit on 225°F

Start the Deck Boss at 225°F. Low = maximum smoke flavor and a slow, controllable climb (~2°/min inside the steak — you cannot be ambushed).
Set the Weber up now so it's grab-and-go later: bottom vent wide open, chimney loaded but unlit, grate off to the side.

T–1:15

Filets on, straight from the fridge

Cold meat takes smoke better — skip the "come to room temp" ritual; it does nothing here.
One probe per filet, into the dead center — on a 2-inch filet, center placement is the whole ballgame. A few inches of air between steaks.
Lid closed. Nothing to do for half an hour but set vent-side snacks.

T–0:55~95° internal

Light a full chimney on the Weber

When the probes read ~95°, light a completely full chimney. It needs 15–20 minutes to go fully gray — timed to peak exactly when the steaks need it.
Fully lit means every coal ashed over. Half-lit charcoal makes acrid smoke — the one way to ruin a $60 pair of filets in 90 seconds.

T–0:45his: 115°

His comes off at 115° — and waits

Loose on a plate, no foil (steam softens the surface you just spent an hour drying).
This is the stagger that gets two doneness levels off one fire: he's parked, she keeps climbing.

T–0:38

Dump the chimney, grate on, let it roar

Coals in a tight pile on one side of the kettle — you want a concentrated inferno, not an even bed. Grate on, lid off, five minutes to get the grate screaming hot.
Pepper both filets now, and brush the faintest film of high-smoke-point oil (avocado) on the meat, not the grate.

T–0:35hers: 125°

Hers comes off at 125°

Straight from the smoker to the sear station — her timing and the coals' timing converge here by design.

T–0:30

The sear — 60–90 s per side, both at once

Both filets directly over the pile. 60–90 seconds, flip, 60–90 more — or flip every 30 seconds with a quarter-turn for a full crust. Edges too: tongs, 20 seconds rolling the sides.
Optional but excellent: last 30 seconds, a pat of butter on top of each as they finish.
Instant-read is the referee: his off at 130–133°, hers off at 140–143°. Flare-ups: slide, don't fight — move the steak, not the fire.

T–0:25

No rest. Plate and serve immediately.

The counterintuitive part: reverse-seared steaks don't need a rest — the slow smoke phase already relaxed the muscle and evened the juices. Resting now only softens the crust you just built.
Compound butter on top, sharp knife, and the crust should still be crackling when it hits the table.

Why Reverse Sear Works

The teach-me-something section. Three pieces of physics, one payoff.

1 — No gray band

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 — then the sear only has to build crust, not cook meat. Result: edge-to-edge pink, crust like a steakhouse.

2 — Dry surface, instant crust

The Maillard reaction (browning) can't start until surface water boils off — 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 — which is also why the gray band stays thin.

3 — A huge margin for error

At 225°F the steak's core climbs about 2° per minute — 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.

Gotchas

Ranked by how much they'd hurt on a cut this expensive.

Will bite you

Thin filets can't do this

Under ~1¼ inches there's no thermal "inside" to protect — 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.

Half-lit charcoal ruins everything

Charcoal that isn't fully ashed over vents acrid, sooty smoke — 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.

Trust probes, verify with the instant-read

The entire method is a ±5° game. Probe dead-center, and spot-check with the instant-read at the pull and during the sear — a probe resting near the edge of a small filet reads 10° hot and turns her medium into medium-well.

Don't sauce, oil, or butter before the sear

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 — same principle, different fat.)

Good to know

Filet needs the butter

Tenderloin is the most tender and least fatty cut — 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.

Carryover happens twice

~2–3° of drift after the smoker pull, ~3–5° after the sear. The pull numbers on this sheet already account for both — that's why "off at 115" becomes med-rare at 130–135 on the plate.

The afterburner option

Party trick with real physics: set a small grate directly on top of the lit chimney and sear there — 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 wait costs nothing

His filet sits at ~113° for ten minutes while hers finishes — 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.

If the Plan Slips

Overshot on the smoker his reads 125 already

He just joined her at medium — 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.

Coals aren't ready, steaks are no problem

Pull the filets at temp and let them sit loose on a plate — 15 minutes costs nothing (see: his wait). Never leave them on the smoker "to hold"; that's how 115 becomes 135.

Rain moved in indoor fallback

The smoke phase still happens under the Deck Boss lid — then sear inside in a screaming cast-iron skillet, 60–90 s/side with a butter baste. Different crust, same science, dry pants.

She says "a little more done" at the table easy

Back on the kettle's cooler edge, 60–90 seconds a side off the direct pile, instant-read to 150. No shame — the method makes corrections cheap.
