3-Step Execution Protocol

1
Preheat & Prep

Preheat oven to 400°F (204°C). Arrange salmon fillets & green beans (one-pan dinner) (4 × 6 oz center-cut salmon fillets and 1 lb trimmed green beans in a single layer on a half-sheet pan, no crowding) on a parchment-lined sheet pan in a single layer. Spray lightly with high-smoke-point oil.

2
Cook

Cook for 12–14 mins. Do not flip; allow surface to develop undisturbed.

3
Check & Rest

Salmon flakes cleanly with a fork and the white albumin has just started to bead on the surface; green beans are blistered where they touch the pan, still with a bit of snap. Confirm internal temperature reaches 145°F (63°C) at the thickest part of the fillet. Rest for 3 minutes before serving.

Verification Basis & Testing Rig

USDA FSIS Safe Minimum Internal Temperatures chart lists 145°F for fin fish. The 12–14 minute window at 400°F is standard center-cut-fillet convection roasting practice for a 1–1.25 inch fillet; thinner tail pieces will finish 2–3 minutes sooner and should be pulled early rather than averaged.

Pro Tip: Roast the beans alone for the first 4–5 minutes, then slide the salmon on. Salmon and green beans look like they should cook in the same window, but the beans are naked vegetable and the salmon is a dense protein — starting the beans first is how you get char on the beans instead of grey, limp beans huddled around perfect fish.
