Baked Cod with Mushroom and Cracker Crust

Tips
Crush crackers finely in sealed bag to avoid mess and ensure even coverage on fish.
Don't skip the intermediate butter layer between fish and crackers - it prevents drying and adds richness.
Check doneness by piercing thickest piece with fork; flesh should flake easily without translucent spots.
Good to Know
Refrigerate in airtight container up to 2 days. Do not freeze - texture degrades from moisture in mushrooms and cracker topping.
Prepare components separately: crush crackers, slice mushrooms, portion cod up to 4 hours ahead. Assemble and bake immediately before serving.
Serve hot directly from baking dish. Pair with steamed green beans, roasted asparagus, or simple lemon rice to balance richness.
Common Mistakes
Don't skip butter between fish and crackers to avoid dry fish.
Don't overbake past 15 minutes or cod becomes tough and flakes excessively.
Don't use fresh basil only - dried concentrates flavor better in baked applications.

FAQ
Can I prepare this ahead and bake later?
Prepare components separately up to 4 hours ahead, but assemble and bake fresh. Pre-assembled dish may absorb moisture and lose cracker crispness.
What if my cod fillet is thicker than average?
Extend baking to 18-20 minutes. Check at 15 minutes by piercing thickest section - flesh should flake easily without translucent center.
How long will leftovers keep?
Refrigerate covered up to 2 days. Reheat gently at 325 degrees F for 8-10 minutes to avoid further drying. Do not freeze.
