Herb-Butter Coho with Crispy Red Potatoes

Score: 8/10

A highly practical and appealing weeknight sheet pan meal. The staged cooking logic is spot on. A few minor adjustments to the salmon cooking time and plating instructions will elevate this recipe and prevent the lean fish from overcooking.

Strengths

Excellent use of the sheet-pan technique with properly staged cooking times for potatoes versus the quicker-cooking fish and broccoli.
Flavor combinations (dill, dijon, butter, garlic, salmon) are classic and highly appealing.
Cost and timing estimates are very realistic for a home cook.

Issues

medium / timing: Baking lean Coho salmon at 425°F for 10-14 minutes is likely to overcook it. While 145°F is the FDA recommendation, it often yields dry fish, especially for leaner species like Coho.
low / presentation: The instruction to plate with a 'swoosh of melted herb butter from the pan' is unrealistic. The pan drippings will be a murky mixture of butter, fish albumen, and vegetable juices, which will not look or perform like a clean butter sauce.
low / flavor: Lemon is listed as an 'optional' ingredient, but the dish is very rich with butter, roasted salmon, and potatoes. Acid is necessary for flavor balance.

Suggested fixes

Reduce the salmon cooking time to 8-12 minutes and suggest checking the thickest part early to prevent the lean Coho from drying out.
Make the lemon wedges a mandatory ingredient, instructing the cook to squeeze fresh lemon juice over the finished dish.
Change the plating instructions to simply drizzle the finished dish with pan juices rather than attempting a restaurant-style 'swoosh' with mixed drippings.
