How I Cook Fresh Rainbow Trout Filets On Top of the Stove
We were having company Sunday night, so my wife and I picked up some fresh trout filets at the farmer's market in the morning after taking our dog Bailey for a hike.
I know one of the fishmongers at the market, and Andy always takes excellent care of me by letting me know what's fresh and a good buy. That day, he recommended the rainbow trout and picked out some beautiful fillets for us.
A Little Bit About Rainbow Trout
Rainbow trout is a species of freshwater fish native to cold-water tributaries of the Pacific Ocean in Asia and North America but has been widely introduced for sport fishing and aquaculture. They are prized for their bright, distinctive coloration and their fighting spirit when caught.
How Big Do They Get?
The size and weight of rainbow trout can vary greatly depending on various factors such as age, habitat, and genetics. In the wild, rainbow trout typically grow to lengths of 8-12 inches (20-30 cm) and weigh between 1-4 pounds (0.5-2 kg). However, larger specimens can be caught, especially in specific habitats.
In aquaculture, rainbow trout are often selectively bred to reach larger sizes, with some farmed fish reaching weights of up to 13 pounds (6 kg) or more. The size and weight of rainbow trout can also be influenced by the availability of food and the length of the growing season in their habitat.
Is It A Healthy Fish?
Yes, rainbow trout is considered a healthy fish to eat. It is a good source of protein, omega-3 fatty acids, and vitamins such as B12 and D.
It also contains minerals like phosphorus, selenium, and potassium. However, as with any food, it is essential to consider factors such as preparation method and portion size when evaluating its overall nutritional impact on a diet.
Ways to Cook Rainbow Trout
Rainbow trout can be cooked in a variety of ways, including:
- Grilled: Season with salt, pepper, and lemon, wrap in foil, and grill over high heat for 8-10 minutes on each side.
- Pan-Fried: Dredge the trout in seasoned flour and fry in a hot, oiled pan for 3-4 minutes on each side until golden and crispy.
- Poached: Place trout in a pot of simmering liquid (such as white wine, water, or court bouillon) and cook until the fish is just cooked through, about 8-10 minutes.
- Baked: Season the trout, place on a baking sheet, and bake at 200°C (400°F) for 10-12 minutes.
- Broiled: Season the trout, place it under the broiler, and cook for 6-8 minutes on each side until the skin is crispy and the flesh is opaque.
- Smoked: Smoke the trout over low heat for 30-45 minutes, depending on the desired level of smokiness.
These are some of the most common cooking methods for rainbow trout, but the fish can also be used in various recipes including soups, stews, and curries.
What Temperature Should You Cook It To?
Rainbow trout should be cooked to an internal temperature of 63°C (145°F). This temperature is high enough to ensure that any harmful bacteria in the fish have been destroyed but not so high that the meat becomes dry and tough.
To check the internal temperature, insert a meat thermometer into the thickest part of the fish, away from bones and cartilage. When cooking rainbow trout, it is essential to avoid overcooking as this can lead to dry, tough meat.
Best Places to Buy Rainbow Trout
Rainbow trout can be purchased from a variety of sources, including:
- Grocery stores: Rainbow trout are often sold fresh or frozen in the seafood section of large grocery stores.
- Fish markets: Independent fish markets specialize in selling various fresh and saltwater fish, including rainbow trout.
- Online retailers: Online retailers specializing in seafood offer rainbow trout for delivery to your door.
- Aquaculture farms: Some fish farms raise rainbow trout and sell it to consumers.
The availability of rainbow trout may vary depending on where you live and the time of year, so it may be a good idea to call ahead to ensure the store or market has it in stock.

Pan Fried Rainbow Trout with Tarragon
As mentioned above, there are many ways to cook fresh fish filets and season them to alter their flavor. The way I'm describing here is very basic and easy to do at home, especially if you are uncomfortable with pan-frying fish.
I have a few tips that are helpful and encourage you to give this method a try.
I used only salt, pepper, and some finely minced tarragon for this dish. When my youngest daughter grabbed the bunch of fresh tarragon from the refrigerator, I asked her to pull off a leave, crumble it up in her fingers, give it a smell, and then take a taste.
She liked the smell but wanted to be more thrilled with the taste. Said it tasted like licorice - which it does. When cooked, the flavor mellows and is excellent with most seafood, chicken, and vegetables. It is an essential ingredient when making Bearnaise sauce.
- Remove the fish from the refrigerator at least 15 minutes before cooking. It is much easier, and you'll get better results if the trout are not cooked directly from the fridge.
- Depending on the size and thickness of the rainbow trout, most recipes will tell you to cook for approximately 3 minutes per side. Good advice, but if you look at a filet of Rainbow trout, you'll notice one end is much thicker than the other. I want to place the thicker ends on the same side of the pan and then place the pan over the heat so the thicker section is directly over the heat. This way, the pan gets hotter under the thickest part of the fish.
- You can start with the skin side down and be sure the pan and oil are nice and hot before adding the trout so the skin crisps up nicely.
- Rather than timing the fish 3 minutes per side, I like to watch it as it cooks. You can see it change color on the sides as it is cooking. When it looks like it is between halfway and three-quarters cooked, flip it over and cook for another couple of minutes until done. It takes a little practice to get the timing right, so start with 3 minutes per side and watch it cook. You can try that method when you get more comfortable with watching and getting a feel for when it is perfectly cooked.
- Don't crowd the pan! I pan-fried six trout fillets, two at a time. When I finished cooking the first two fillets, I removed them to a plate, loosely covered them with tin foil, and let the pan get hot again for a minute before adding the following 2 pieces of trout.
- Don't use dried tarragon. Find some fresh tarragon in your market for this recipe.
- Read my post on How to Prevent Fish From Sticking to the Pan. I think you'll enjoy it.
We served the Rainbow trout with fresh local seasonal corn and a delicious Arugula Salad with Peaches. I'll work on posting the recipe for the arugula salad soon.
How To Cook Rainbow Trout Filets
- 6 filets trout
- salt & pepper to taste
- 6 tablespoons olive oil
- 2 tablespoons fresh tarragon minced
- Prep the ingredients by washing and drying the fresh tarragon leaves and removing the leaves from the stems. Discard the stems. Finely mince the fresh tarragon.
- Rinse and dry the rainbow trout.
- Heat up a large frying pan over medium heat, one that will hold at least 2 of the trout fillets. How hot? This is important because you must be careful when adding oil or any fat to a heated pan.
- While the pan is heating, season the skin side of the trout with salt and pepper.
- When the pan is hot enough, add a tablespoon or two of oil to the pan and move the pan around so the oil coats the bottom. When the oil gets hot but not smoking, add the trout fillets skin side down.
- While the trout is cooking, season the non-skin side with salt, pepper and some of the tarragon. Depending on the thickness of the fillets, cook for approximately 3 - 4 minutes until the skin is crispy.
- Flip the trout fillets over and cook for 2 - 3 minutes or until the fish is perfectly cooked through. Transfer the cooked trout to a plate, loosely cover with foil to keep warm while you cook the remaining fillets.I like to bring the pan back to the stove, add a little oil if needed and let the pan and oil get hot again before adding the next pair of trout fillets. If the pan isn't hot, the skin will not crisp up as nicely as the first batch.
- When all the rainbow trout fillets are pan fried, plate with your side dishes and serve.
