Chef's Tips

Choose Fresh Trout

Look for firm flesh, clear eyes (if whole), and a clean, fresh aroma.

Dry Before Roasting

Patting the trout dry helps it roast evenly and develop a lightly crisp surface.

Fresh Herbs Make a Difference

Fresh herbs provide brighter flavor and aroma than dried herbs.

Avoid Overcooking

Trout cooks quickly. Remove it from the oven as soon as it flakes easily to keep it moist.

Baste Before Serving

Spoon the flavorful pan juices over the fish just before serving for extra moisture and flavor.
