Why I Love Steelhead Trout for Blackening

Steelhead trout and salmon show up in my meal planning at least twice a month, sometimes more. When steelhead trout is available, I try to grab as many packs as I can because I love the lighter fish flavor. When I want my seasonings to shine, steelhead trout wins over salmon every time. And what better way to use it than with this easy blackened steelhead trout recipe? It’s bold, quick, and full of flavor, just how I like it. I mean, I am a spice girl. (tap on drum) Get it? Spice girl. You kind of had to be there in the late 90s. Singing “tell me what you want, what you really really want”; that’s about all I remember from the lyrics. Yep, telling my age here. Okay, back on track.

Ingredients for This Easy Blackened Steelhead Trout Recipe

This recipe uses pantry staples and a few fresh basics, but each one pulls its weight. The blend is spicy, earthy, and just a little sweet. Don’t be afraid to tweak it. I’ve added notes below in case you’re missing something or just want to play around a little.

For the Blackened Seasoning

  • 1 tablespoon regular paprika
    Adds body and that classic red-orange color. Use basic paprika here, not smoked, you’ll get smokiness from another ingredient.
  • ½ teaspoon smoked paprika
    Just enough to give the fish a little edge and depth without overpowering it.
  • 1½ teaspoons granulated garlic
    Granulated garlic gives better coverage than garlic powder and won’t clump as easily. If all you have is powder, it’ll still work just fine.
  • 1½ teaspoons granulated onion
    Same idea as the garlic, granulated works best for seasoning blends, but onion powder is okay in a pinch.
  • 1 teaspoon cayenne pepper
    This is where the heat comes in. You can totally customize it. If you’re not into spice, even ¼ teaspoon will give it just enough kick to wake things up without being too much.
  • ½ teaspoon dried thyme, crushed
    Crush it between your fingers or use a mortar and pestle. No thyme? Marjoram works great as a substitute.
  • ½ teaspoon dried oregano, crushed
    Go for Mediterranean oregano, Greek, or even Mexican oregano if that’s what you’ve got. Marjoram is also a good substitute here. They all bring something nice to the party.
  • ½ teaspoon black pepper
    Brings sharpness and heat.
  • ½ teaspoon white pepper
    Softer and a little more earthy than black pepper. If you don’t have any, it’s fine to just double the black pepper.
  • 2 to 2½ teaspoons salt (to taste)
    I like it bold, but if you’re not a salt lover, start with less. You can always add a pinch more after cooking.
  • ½ teaspoon brown sugar
    Just a touch of sweetness helps the fish brown better and balances out the spice. It also helps create that crust in the pan and is not optional.
  • ¼ to ½ teaspoon crushed fennel seeds
    Crush them as fine as you can. Fennel gives this seasoning a little something extra that sets it apart. It’s the same flavor you find in Italian sausage, but don’t worry, it won’t make your fish taste like sausage. Promise.

For the Fish

  • 4 steelhead trout fillets, skin-on (about 5 to 6 ounces each)
    Make sure they’re cleaned, patted dry, and ready to go. Dry fish sears better and helps the seasoning stick.
  • 1 to 2 tablespoons neutral oil (like avocado or light olive oil)
    I rub just a bit of oil on the fillets to help them crisp up. You can skip it if you want to press the seasoning in dry, but the oil does help everything stick and cook evenly.
  • Lemon wedges, for serving
    A little fresh lemon at the end brightens it up.
  • Fresh parsley or green onion, optional for garnish
    Totally optional, but it adds color and freshness if you want to dress things up.

How to Pan-Sear Blackened Steelhead Trout

1. Prep the Fish:
Pat the steelhead trout fillets dry with paper towels. Rub a thin layer of neutral oil like avocado or light olive oil on both sides. This helps the seasoning stick and gives a better crust.

2. Season Generously:
Sprinkle the blackened seasoning evenly over both sides of each fillet, including the skin. Press gently so the rub sticks well.

3. Heat the Pan:
Use a cast iron or heavy stainless steel skillet. Heat it over medium-high until very hot. Flick a drop of water in the pan. It should sizzle and evaporate immediately.

4. Sear Skin Side Down:
Add a small amount of oil to the pan to lightly coat the surface. Place the fillets skin-side down. Press lightly with a spatula to keep the fish flat and prevent curling. Cook undisturbed for 3 to 4 minutes until the edges turn opaque and the crust forms.

5. Flip and Finish Cooking:
Use a cast iron or heavy stainless steel skillet. Heat it over medium-high until very hot. Flick a drop of water in the pan. It should sizzle and evaporate immediately.

The Bold Origins of Blackening

Blackening got its start in Louisiana and became widely known thanks to Chef Paul Prudhomme back in the 1980s. He used this method to bring big, deep flavor to fish, especially redfish, and folks couldn’t get enough. The technique involves coating the meat or fish in a punchy spice mix, then cooking it quickly in a hot cast iron skillet. That high heat gives it a dark, flavorful crust that’s full of smoky, spicy goodness. It’s bold without being fussy, which is exactly why I love using it for steelhead trout.

Tips for the Best Blackened Steelhead Trout

Start by making sure the fish is patted completely dry. That’s the key to getting a good crust. Use a heavy skillet like cast iron or stainless steel so the heat stays even. When you season the fish, sprinkle the spice mix generously and press it in gently with your fingers so it really sticks. Don’t crowd the pan, give each piece space or cook in batches if you need to. Once it’s in the pan, let it cook without moving it around. That’s how the crust forms. And if things start to smoke too much or brown too fast, just lower the heat a touch. You want it hot enough to sear but not so hot that it scorches.
