Lemon-Garlic Half Chicken with Asparagus & Gold Potatoes

Score: 7/10

A conceptually strong, appealing spring sheet-pan meal with a major technical flaw: placing fresh minced garlic and mustard on the chicken skin will cause them to burn at 425°F.

Strengths

Smart use of a single sheet pan to minimize cleanup.
Correctly stages the vegetables by adding the quick-cooking asparagus later in the process.
Excellent flavor profile featuring a classic and appealing combination of lemon, garlic, and Dijon.
Appropriate use of finishing acid (lemon juice) and fresh herbs to brighten the final dish.

Issues

high / flavor: Minced garlic rubbed directly on the chicken skin and exposed potatoes will burn and turn extremely bitter during a 40-45 minute roast at 425°F.
medium / cookability: Dijon mustard rubbed on the outside of the chicken skin can inhibit proper crisping and is also prone to burning at high heat over a long duration.
medium / timing: Roasting asparagus for 10-15 minutes at 425°F will likely overcook it unless the spears are unusually thick.
low / nutrition: A 1.75 to 2 lb half chicken is an exceptionally large portion for a single-serving lunch.

Suggested fixes

Instruct the cook to rub the minced garlic and Dijon mustard *under* the chicken skin. This protects them from burning, flavors the meat better, and allows the skin to crisp.
Omit the fresh minced garlic on the potatoes, swap for garlic powder, or add the fresh garlic to the potatoes in the last 10 minutes of roasting.
Reduce the asparagus roasting time to 7-10 minutes.
Consider framing the recipe as a serving for two, or note that it provides planned leftovers.
