What is steelhead trout?
Steelhead trout is a type of coastal rainbow trout. Steelhead trout is a sea-run fish that returns to freshwater to spawn (deposit eggs into water) after living in the ocean for about 2 years. It's a species of salmonid, which means steelhead trout is related to salmon, char, and freshwater whitefish.
What seasonings go well with steelhead trout
Steelhead Trout is a delicate fish that does need strong spices. Here is how you can enhance the flavor of trout with these simple ingredients:
- Use basic seasonings, such as salt and pepper, minced garlic, and lemon slices.
- Italian seasoning or Herbs de Provence is always a great choice for any kind of trout.
- Dried and fresh herbs pair well with any fish. Thyme, dill, oregano, and parsley are my favorite. You can also add rosemary or marjoram.
- For bolder flavor, make your own dry rub for steelhead trout. Combine small amounts of smoked paprika, chili powder, garlic powder, onion powder, salt & pepper, and dried herbs (such as thyme, oregano, marjoram, and parsley).

I highly recommend that you try steelhead trout - it's tasty, easy to handle, and very healthy (at least, according to this website).

How to cook steelhead trout
Cooking the steelhead trout involves seasoning the fish → searing it on the stovetop → making the sauce → assembling the final dish! Follow along with these easy instructions!
Part 1. Season the trout
Season 1.5 lbs of steelhead trout fillets with 1 tablespoon of Italian herb seasoning and salt. Fish fillets usually will have skins on the bottom, so it's enough to season just the top side of the fish.
Part 2. Cook the steelhead trout on the stovetop
- Heat olive oil on medium heat in a large skillet. Adding 1 tablespoon of olive oil is enough as fish will release lots of its own oil (steelhead trout is a fatty kind of fish).
- Add steelhead trout fillets, skin side up, non-skin side down. Cook for about 2 minutes on medium heat, making sure the oil does not smoke. Turn the fillets over, skin side down. Cook for another 2 minutes on medium-low heat.
- Then, allow the trout to rest in the skillet. Remove the skillet from heat, close with the lid, and let the steelhead trout sit for 5-10 minutes until flaky and cooked through completely.
- Finally, separate trout flesh from the skin. After the fish is cooked through, using a spatula, carefully remove trout fillets to the plate, separating the fillet from the skin (skin will remain on the bottom of the pan).
- Carefully scrape the fish skin off the bottom of the pan, making sure to leave the fish oil in the pan. Note: You will use this same skillet to make garlic butter lemon caper sauce as described in the next section.
Part 3. How to make Lemon Caper Sauce
Lemon caper sauce with garlic and butter is what makes this steelhead trout so tasty!
- Add capers, minced garlic, and lemon juice to the same pan that you just used to cook steelhead trout. The pan will still have oil and juices remaining from cooking the fish.
- Heat up the sauce gently on medium-low heat for about 1 minute, until garlic softens a bit. Remove from heat.
- Add butter, off heat, to the caper sauce, stirring, until butter melts and forms a creamy mixture.
Part 4. Final Assembly
Add fish back to the pan, spoon sauce over the fish, and serve.
What to serve with steelhead trout
- Roasted or grilled vegetables, such as asparagus, broccoli, or zucchini. Sliced bell peppers, red onions, squash are also great choices.
- Rice. Jasmine rice is an excellent side for steelhead trout. For more flavor, serve wild rice or flavored rice. You can even serve cauliflower rice.
- Quinoa. Plain or flavored quinoa is an amazing grain that goes well with fish.
- Potatoes. Mashed sweet potatoes are a great side for trout. Potatoes roasted with herbs and garlic in olive oil are also a fantastic choice.
- Leafy Greens. Make a simple green salad by tossing together spinach, kale, or arugula with a small amount of your favorite salad dressing. Or make your own simple dressing by combining olive oil and a splash of balsamic vinegar. Top the salad with your favorite cheese (example: Parmesan, Goat Cheese, Feta) and a handful of nuts or seeds.

Made this last night for my husband, who is a very picky eater, and he thought it was fantastic. The capers gave it so much flavor.
This was really delicious! My whole family loved it!
My lady friend gave me this whole bottle of capers, being Spanish American; that I use continuously on anything I can think of. Later I caught these 4 hefty beautiful steelhead. Then I ran into your recipe which includes plenty of capers. A match made in heaven. TY much.
Easy, fast and delicious. My husband loved it and said he will "accidentally" buy the Steel Head Trout again so that he can have it cooked like this (he thought he was buying salmon)
This will be on our regular rotation
Thank you
So, I meant to buy salmon and realized after I got home that I purchased steelhead trout. So....I looked up a recipe and found yours. So many great reviews! My 4 older children (10, 8, 6 and 3) devoured this and gave it an A! (We like to rank new dishes we try.) I did not like seafood growing up and am learning to like it as an adult and both my husband and I enjoyed this dish VERY much! Thank you for sharing! I love how quickly it cooks, too. We will definitely have this again.
Excellent. So easy and so tasty.

Missed the fact that the recipe called for the 1.5 lbs. of trout to be divided up into 3 fillets. I had 1.8 lbs. divided into 2. I followed the directions but it did not fully cook through, I assume because of the larger pieces. I had to start over and do a second round of 1.5 minutes per side and then remove it from the heat and cover for another 5-10 minutes. In the end, it came out delicious, but I think I should have salted it a bit more. I served the trout over rice with a side of spinach.
Hi Mary! Glad you tried the recipe and liked it! Serving this with rice and spinach is delicious.
Used on steel head trout filets. They came out delicious .
Absolutely fabulous! I used rainbow trout. I was afraid there wouldn't be enough sauce, but it was the perfect amount. Thank you for sharing this recipe I can't wait to try your other recipes.
