Total time is about 50 minutes (25 min prep + 25 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.
How do I store leftover Lime-Marinated Trout with Andean Potato Mash?
Refrigerate in a covered airtight container for up to 3–4 days (FDA FoodKeeper guideline for cooked fish).
