Lemon-Thyme Cod with Autumn Vegetables

A well-paced, flavorful sheet-pan cod dinner that needs minor fixes to prep sequencing, doneness temperature, cost estimation, and the Brussels sprouts salt level.

Score: 7/10

Suggested fixes

Move vegetable cutting, herb stripping, garlic mincing, lemon prep, and fish seasoning to the beginning of the instructions before putting the potatoes in the oven.
In Step 6, roast the cod for 8–10 minutes until it flakes easily and reaches 135–140°F at its thickest point.
Reduce the salt on the Brussels sprouts in Step 3 from 1/2 teaspoon to 3/8 teaspoon (or a generous 1/4 teaspoon) fine sea salt, and update the total salt in the ingredient list to 1 1/2 to 1 5/8 teaspoons.
Update estimated_cost_dollars to 20 (or around 18 if prorating bulk garlic and thyme) to reflect the listed item prices.

Issues

medium / clarity: Prep work is split across active roasting steps instead of starting with full mise en place before active cooking begins.
medium / flavor: Step 6 cooks the cod to 145°F plus a 2-minute rest, which tends to make lean white fish chalky and dry; pulling lean white fish at 135–140°F preserves a moist, flaky texture.
low / flavor: Using 1/2 teaspoon fine sea salt (about 3 grams) on 8 ounces (227 grams) of Brussels sprouts is roughly 1.3% salinity, which is slightly heavy for roasted sprouts that lose moisture in the oven; 3/8 teaspoon (or a generous 1/4 teaspoon) is closer to the 1% vegetable target.
low / cost: The priced ingredients alone total $19.84, so estimated_cost_dollars: 13 understates the actual checkout cost (or miscalculates even a prorated cost).

Strengths

Staggered roasting times for potatoes, Brussels sprouts, and cod ensure everything finishes cooking at the same time.
Ingredient amounts in the steps match the master ingredient list exactly, with proper use of bulleted lists for 4+ ingredient mixtures.
Seasoning on the cod (3/4 teaspoon fine sea salt for 12 ounces) and potatoes (1/2 teaspoon fine sea salt for 12 ounces) is spot on.
