What is steelhead trout?
Steelhead trout is a type of coastal rainbow trout. Steelhead trout is a sea-run fish that returns to fresh water 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.
As I was cooking this beautiful steehead trout, 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. It’s a pretty fatty fish, it doesn’t stick to the pan and cooks fast and easy thanks to its rich fat content! 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
- First, season the fish. Season the tops of trout fillets with Italian herb seasoning and salt (generously). Fish fillets will have skins on the bottom.
- Next, cook the trout on stove-top. In a large skillet, heat olive oil on medium heat. 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 trout fillets, skin side up, non-skin side down. Cook for about 1.5 minutes on medium heat, making sure the oil does not smoke.
- Turn the fillets over, skin side down. Cook for another 1.5 minutes on medium-low heat.
- Then, allow the trout to sit in the skillet. Remove the skillet from heat, close the pan 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 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. You will make garlic butter lemon caper sauce in the same pan as described in the next section.
How to make Lemon Caper Sauce
Lemon caper sauce with garlic and butter is what makes this steelhead trout so tasty! Add capers, diced garlic, and lemon juice to the skillet.
