Parmesan Pesto Steelhead and Roasted Potatoes
All cooked on a single sheet pan for maximum flavor and minimum mess. Flaky, tender, delicious fish that is oh so flavorful, this is sure to be your favorite meal, along with tender potatoes baked to perfection in a basil pesto and parmesan. Delicious. Steelhead is a trout that looks and tastes like salmon. They are in the same family, but steelhead has a stronger, richer flavor! You are going to love it.
Steelhead is something I grew up eating. And to this day, one of my favorite fish to prepare. It holds significant family memories and a special place in my heart. This Parmesan Pesto Steelhead and Roasted Potatoes is a recipe I am so excited to share because it makes me think of my family. Of my Grandpa, and my own dad.
My Family
One of my fondest memories from growing up was spending summers in a little town in Idaho on the Salmon river. My grandparents lived there, and my dad grew up there, and it is the kind of place that holds magic. Despite having traveled much of the world, this tiny town with a population of 3000 people, holds a huge piece of my heart.
My grandpa was the small town doctor, and the whole community loved him. I was blessed genetically to strongly resemble my dad’s side of the family, so never fail when I would visit, people from the town would recognize me as a relative of Doc Simmons. As a small child this always made me feel like a celebrity.

Grandpa Simmons
Doc Simmons, or Grandpa Simmons, as I knew him, was quite the outdoors man. He worked hard. Very hard, with long clinic hours and hospital hours, and middle of the night calls to deliver babies, or help the sick or injured. But one thing he was always good at was playing hard too. He knew just how to enjoy life, and spent a good part of it on the river. He had this great raft, and we would raft. And fish.
This is a photo of him with my dad and uncle, enjoying the river! It always brings a smile to my face, and a tiny tear to my eyes. You guys, when it comes to my Grandpa I am a sentimental fool.
Just look at the smile on his face! Anyway, he enjoyed taking us fishing. This was a man with endless patience. I never could understand how to just sit still and wait for the fish to bite. But I loved spending time with my grandpa. So I fished. And one of the neat things about this river is that you can catch salmon in it, but you can also catch steelhead
So today, I wanted to share this amazing, mouthwateringly delicious Parmesan Pesto Steelhead and Roasted Potatoes recipe, share a little about my family, and my family history.
Parmesan Pesto Steelhead and Roasted Potatoes
This recipe for Parmesan Pesto Steelhead and Roasted Potatoes is inspired by my experiencing growing up, the beautiful town my grandparents lived in, and the fact that my parents now live in the same town, on the same river. And I am carrying on the tradition of taking my kids to the Salmon River during the warmer months. And floating the river, and fishing it, and hiking, and playing.
This Parmesan Pesto Steelhead and Roasted Potatoes recipe is the easiest recipe you will ever make! It is like 3 ingredients, but tastes like something you would get in a fancy restaurant. It is amazing. The potatoes are flavorful and delicious with a basil pesto sauce and parmesan cheese, and the fish is flaky, tender, not super fishy, and the pesto and parmesan are the ideal flavor compliment. Yum!
Steelhead Recipe Need to Know:
- Where to get Steelhead: Pick up Steelhead at Costco or your local seafood counter.
- Substitutions: Feel free to replace with Salmon filet if you can’t find Steelhead. It is similar and both are delicious. Steelhead is a trout, but it is part of the same fish family as Salmon, resembles it but has a richer flavor and color.
- Cooking Perfectly: Baking time should be adjusted for the thickness of the filet, and preferred doneness. If it flakes easily, it is done.
- Ease: This is a one sheet pan meal, which means easy clean up! Enjoy the lack of mess to clean up by spending time having fun conversation with your family. I love my Nordicware sheet pans because they are big, heat evenly, and are made of aluminum so they will never rust.
- Tips: I used a premade basil pesto that I picked up at Costco when I bought the Steelhead, and it was excellent. You could do the same, or make your own.
Anyway, I hope you enjoy this Parmesan Pesto Steelhead and Roasted Potatoes recipe as much as we do. My 4 year old loves it, like loves it. And my oldest asked if I could teach him how to cook Steelhead, so he made dinner on Sunday, and cooked a beautiful filet. We are already making our plans for going Steelhead fishing, which happens to take place during the cold winter months. Check out this fun picture of my Uncle with his Steelhead catch!
Enjoy!

Baking this right now. Can’t wait to eat it. It smells so good. Love the memories of Grandpa Simmons. It brought tears to my eyes and happiness to my heart.

James Simmons says
The ice broke loose and a channel formed in the river again, with about 8 to 10 foot walls down to the river. Captain Kirk and I figured out a way to get him down into the river. He quickly caught to big steelhead, and we cooked them up using this recipe. Wow, that tasted amazing! It was magical being able to catch the first fish out of the river since the ice cleared! Just like when grandpa was here! Love Dad!
P.S. Ladies, the good looking guy holding the steelhead is my brother, Rachael’s uncle. If you like to fish, you’ll love him, and he is available too:)

Looks delicious, could you replace the trout with chicken?
