This elegant steelhead trout recipe transforms simple ingredients into a restaurant-worthy dinner. The combination of crispy-skinned fish, earthy mushrooms, tender new potatoes, and vibrant truffled pea sauce creates a perfect harmony of flavors that celebrate spring's bounty.

I first made this dish when trying to recreate a memorable restaurant experience at home. What started as an experiment has become my go-to impressive dinner when I want to treat myself or loved ones to something special without spending hours in the kitchen.

Ingredients

  • Fresh steelhead trout fillets: With skin crisp up beautifully and provide the perfect canvas for the vibrant sauce
  • Baby new potatoes: Provide hearty substance and their creamy texture balances the dish perfectly
  • Fresh or frozen peas: Form the base of a silky sauce that brings brightness to each bite
  • Truffle oil: Adds luxurious earthy notes that make this dish truly special look for good quality oil as a little goes a long way
  • Fresh herbs: Like tarragon or basil bring aromatic complexity choose based on what looks freshest at the market
  • Mushrooms: Add umami richness and meaty texture cremini work well but splurge on morels when in season

Step-by-Step Instructions

Prepare the potatoes:
Boil baby potatoes in generously salted water for 20-25 minutes until fork tender. The key is checking them regularly as different sizes cook at different rates. Once done, toss with butter, salt and pepper while still hot so they absorb the flavors.
Create the truffled pea sauce:
Blanch fresh peas for just 2 minutes until they float to maintain their vibrant color. Immediately shock in ice water to preserve the bright green hue. Blend with water, oils, lemon juice, garlic, herbs and seasonings until velvety smooth. The consistency should be pourable but not watery, adding a touch more water if needed.
Sauté the mushrooms:
Heat olive oil and butter in a skillet until the butter stops foaming. Add diced shallots first to soften, then add mushrooms. Cook over medium heat without stirring too frequently to allow proper browning and caramelization. This develops deeper flavor and takes about 5-7 minutes. Season at the end to prevent mushrooms from releasing too much water.
Cook the fish perfectly:
Pat fish dry and season generously on both sides. Heat oil in a skillet until shimmering but not smoking. Place fish skin side down and press gently with a spatula for the first 30 seconds to prevent curling. Allow to cook undisturbed for 3-4 minutes until skin is golden and crisp. Flip carefully and finish cooking just until fish is barely opaque in the center.
Plate with precision:
Warm the pea sauce gently over low heat, being careful not to boil which would dull its color. Ladle sauce onto warmed plates, arrange potatoes around the sauce, then place fish skin side up to maintain crispness. Top with sautéed mushrooms and finish with a few strategic drops of truffle oil and a small herb sprig for visual appeal.

Truffle oil is my secret weapon in this recipe. I discovered its transformative power years ago when a chef friend drizzled some over a simple vegetable dish. That first aromatic bite changed my cooking forever, and now I keep a small bottle for special dishes like this one where it truly shines without overwhelming.

Make-Ahead Strategies

The truffled pea sauce is the perfect component to prepare in advance. You can make it up to two days ahead and store it in an airtight container in the refrigerator. When ready to serve, gently reheat it over low heat, stirring occasionally. If it thickens too much in storage, whisk in a tablespoon of water to restore its silky consistency. Having this component ready makes the final assembly much quicker when you're ready to serve.

Perfect Pairings

This springtime dish calls for a crisp white wine with good acidity to complement the richness of the fish and cut through the creamy pea sauce. A Sauvignon Blanc or unoaked Chardonnay works beautifully. For a non-alcoholic option, sparkling water with a squeeze of lemon and a sprig of mint echoes the fresh flavors in the dish. Complete the meal with a simple green salad dressed with lemon vinaigrette to balance the richness of the main course.

Seasonal Adaptations

While this recipe shines with spring peas, you can adapt it throughout the year. In summer, substitute the pea sauce with a vibrant basil or mint pesto. Fall calls for a butternut squash puree with sage. Winter works beautifully with a celeriac or parsnip puree flavored with thyme. The technique remains the same, but these seasonal variations keep the dish relevant and exciting year-round while using ingredients at their peak flavor.
