How to Make Oven-Baked Steelhead Trout with Lemon-Dill and Horseradish Cream Recipe

Step 1: Preheat and Prepare

Start by heating your oven to 400°F. Lay out a baking sheet lined with parchment paper or foil—make sure it’s large enough so you can fold it over the fish to form a sealed packet. This helps lock in moisture and flavor while the trout bakes.

Step 2: Season the Trout

Gently pat the steelhead trout fillet dry with paper towels. Place it skin-side down on the prepared parchment or foil. Take a moment to use tweezers and remove any remaining pin bones; this step ensures a smooth eating experience. Sprinkle the salt and black pepper evenly over the fish to bring out its natural flavors.

Step 3: Add Butter, Oil, Garlic, Dill, and Lemon

Drizzle the melted butter and olive oil over the fillet, giving it luxurious moisture and helping to carry the herbs and garlic flavors. Scatter the finely minced garlic and freshly chopped dill on top. Finally, arrange thin lemon slices evenly over the fillet for that bright, sunny burst of citrus.

Step 4: Seal the Packet

Fold the parchment or foil over the trout and crimp the edges tightly to create a sealed packet, also known as “en papillote” style. Be careful not to press too tightly against the fish so it has room to steam and cook gently inside.

Step 5: Bake to Perfection

Place the packet on your baking sheet and slide it into the oven. Bake for about 18 to 22 minutes, depending on the thickness of your fillet. The trout is perfectly cooked when it flakes easily with a fork, turns opaque throughout, or reaches an internal temperature of 145°F. The result will be moist, tender, and infused with all those wonderful flavors.

Step 6: Whip Up the Horseradish Cream

While the fish cooks, mix the horseradish cream in a bowl by whisking together the sour cream, prepared horseradish, lemon juice, chopped dill, sugar, salt, and freshly ground black pepper. If you have time, chill the sauce for 10 to 15 minutes before serving to let the flavors really come together.

Step 7: Rest and Dress

When your fish is done, carefully open the packet to avoid the steam. Transfer the fillet to a serving platter and let it rest for about five minutes. Spoon some of the buttery cooking juices from the packet over the top to keep every bite juicy and delicious.

Step 8: Serve with Style

Garnish the trout with fresh dill sprigs and serve alongside lemon wedges and the cool, creamy horseradish sauce. This final touch makes the entire dish sing.

Creative Ways to Present

For a special occasion, present individual portions nestled on banana leaves or adorned with edible flowers to elevate the visual impact and surprise your guests.

Make Ahead and Storage

Storing Leftovers

If you have any leftovers, store the steelhead trout in an airtight container in the refrigerator for up to two days. Make sure the fish has cooled to room temperature before sealing to maintain the best texture and to avoid condensation.

Freezing

While the delicate texture of this oven-baked trout is best enjoyed fresh, you can freeze leftovers by wrapping them tightly in plastic wrap followed by aluminum foil to minimize freezer burn. Use within one month for optimal flavor and texture.

Reheating

To reheat, gently warm the trout in a low oven set to 275°F, covered loosely with foil to keep it moist. Heat just until warmed through to avoid drying out the tender fish. Reheat the horseradish cream separately at room temperature or chilled alongside your meal for the best experience.

FAQs

Can I use another type of fish for this recipe?

Absolutely! While steelhead trout is perfect because of its flavor and texture, you can substitute with salmon or Arctic char for similar results. Just keep an eye on the cooking time as thickness can vary.

What should I do if I don’t have fresh dill?

Dried dill can be used in a pinch, though fresh dill has a brighter flavor that really makes the dish pop. If using dried, reduce the amount to about one teaspoon, and add it earlier in the cooking process to help it rehydrate and release its aroma.

Is the horseradish cream sauce spicy?

The sauce has a gentle kick from the horseradish, adding lively heat without overwhelming the fish. You can adjust the amount of horseradish to your preference, starting with less and adding more if you like it spicier.

Can I prepare this recipe gluten-free?

Yes, this recipe is naturally gluten-free! Just double-check that the prepared horseradish you buy does not contain any gluten additives, and you’re good to go.

What is the best way to check if the trout is fully cooked?

Look for the fish to flake easily with a fork and become opaque inside. If you have a food thermometer, an internal temperature of 145°F confirms perfectly cooked trout that’s safe and delicious to eat.
