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).
Easily adaptable recipe
As I was cooking this, I couldn't help thinking that this recipe would work great with salmon as well! Steelhead trout is an incredibly easy fish to cook. And it's very closely related to salmon.

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.

What an amazing dish! Really fabulous. I let mine sit in the pan covered longer than 10 minutes as I was waiting for my rice to cook an husband to get home. I forgot to add the butter at the end, but it was amazing. Definitely will make this again!
I don't really care for capers but I found they added just the right amount of saltiness to the fish. I will make this again. Served this over egg pappardelle.
So glad you gave this recipe a try and enjoyed it! Capers are perfect for adding saltiness to some recipes!
Made this with salmon the other day it was delicious.
So glad you liked it! Thanks for the comment!
I have made the recipe several times over the last few months and each time I love it more. It’s quick and delicious. I leave it in the pan off heat at least 10 minutes but would even go up a couple depending on thickness of the fish. Don’t skip letting it sit. This is a delicate fish and needs to finish off heat. Also, I LOVE the caper sauce. Would leave it out. Costco has huge jars of capers that are a great bargain! And I admit, I cheat and use jarred minced garlic and lemon juice from a squeeze bottle. I’ve tried it both ways and honestly, I don’t find much of a difference. Both ways it was a delicious result.
Carol Ann, your comment made my day! So glad you've been enjoying this recipe! Thank you for your feedback and the 5-star review. I really appreciate it!! 🙂
Thanks for sharing this amazing recipe - my family loved it! I will be sharing this recipe with my friends - hope they will like it!
Glad you liked it! Thanks for stopping by and for the 5-star review!
I have to admit, I was in a rush and didn’t make the sauce….I had pan fried my beautiful fish in olive oil and simply added a teaspoon of ghee as I turned the fish. Served alongside a mix of fresh pan sauteed Brussels sprouts, creamer potatoes and red onion. The potatoes were leftovers I halved and tossed in olive oil and garlic along with the sprouts. All great! Dinner in 20 minutes.
Note, I often end up buying too much fish for the two of us. Tonight I had .85 pounds (~14 oz), so used a knife and scissors for the tough skin to cut portions before cooking. The thin filet ends cooked fast and left the skillet early to be served alongside parmesan scrambled eggs the next morning….very decadent!
Lauren, I am so glad you enjoyed this recipe. Your side dishes are perfect: love the Brussels sprouts and potatoes in olive oil. Thank you so much for stopping by and sharing such positive feedback - I really appreciate it!!

I hope you like this recipe - let me know if you give it a try!
I would cook longer but other wise delicious. Used thyme instead of Italian seasoning and a dash of whipping cream after the final butter. Got rave reviews. Especially the caper sauce.
