Reheating:
Reheat gently in the oven at 300°F (150°C) for 8–10 minutes, or in a skillet over low heat until warmed through. Avoid overcooking to preserve the fish’s tenderness.

FAQs
Can I use trout fillets instead of whole trout?
Yes, fillets can be used and will cook slightly faster—check for doneness after 8–10 minutes.
How do I know when the trout is fully cooked?
The flesh should be opaque and flake easily with a fork. An internal temperature of 145°F (63°C) is ideal.
Is the skin edible?
Yes, rainbow trout skin is thin and can be enjoyed when crisped on the grill or in the oven.
Can I prepare this recipe ahead of time?
You can prepare the marinade and fish up to 4 hours in advance and refrigerate until ready to cook.
What sides pair well with this dish?
Try roasted vegetables, quinoa, couscous, or a fresh green salad for a balanced meal.
Can I cook this recipe in foil?
Yes, wrapping the trout in foil will steam the fish and make cleanup easier, though you’ll lose a bit of crispness.
Is this recipe gluten-free?
Yes, all ingredients are naturally gluten-free.
What type of trout should I use?
Rainbow trout is ideal, but any fresh whole trout will work.
Do I need to scale the trout?
If it hasn’t been pre-cleaned, yes—ask your fishmonger or use a fish scaler before cooking.
Can I add vegetables to cook with the fish?
Yes, thinly sliced onions, fennel, or cherry tomatoes can be added to the baking dish for added flavor.
