I always buy salmon because I love this fish. Here in Canada, salmon is pretty popular. We can find it easily in absolutely every grocery store.
But the last time my husband went to the store by himself, he bought a rainbow trout fillet instead of salmon for my Spicy Salmon Sweet Potato Skillet.
I liked it because it’s always good to change things up a little bit. If you enjoy salmon like me, you will love this fish too since it tastes similar, although trout tends to be a little stronger in flavor.
Ingredients to make rainbow trout Recipe
I made this Rainbow Trout recipe last Sunday. I was really tired and wasn’t in a mood to cook a complicated meal and clean up all the mess later. For this reason, I decided to roast the trout in foil, making cleanup a breeze!
- Rainbow trout fillet — try to find a high quality trout. If buying fresh, check for shiny scales and firm flesh. For frozen fillets, check to make sure that there aren’t any dried out edges. You can also make this recipe with steelhead trout.
- Salt and fresh ground black pepper — to taste
- Butter — you can use ghee or olive oil if you are paleo or doing whole30. Be sure to use unsalted butter.
- Garlic — freshly minced. If you don’ have fresh garlic you can use garlic powder, though fresh is better.
- Dill — I like to use fresh dill. Swap for a different herb if you’re not a fan of dill.
- Lemon slices – when you fish is done, top with some lemon slices before serving. Or you can also fresh lemon juice on the top of it.

- First, preheat the oven to 375ºF.
- Second, cut a sheet of foil that is large enough to wrap the trout fillet very well.
- Then, cover the baking sheet with the aluminum foil, and place the trout fillet in the center. Fold up all 4 sides of the foil and making sure to not cover the fillet entirely at the moment.
- Now, place trout on prepared baking sheet and use paper towels to pat the fish dry. season the trout with any herbs you have on hand, such as parsley, dill, or oregano. And of course, let’s not forget salt, black pepper, some garlic, and red crushed pepper.
- For more flavour and to avoid the fish from becoming dry, melt some butter in the microwave or on the stove and drizzle it over the trout until evenly coated.
- Fold the sides of the foil over the trout and cover the trout completely. And then, bake for about 13 minutes. The cooking time will depend on the size of the trout fillet. Now, open the foil, and broil for 3 minutes. Done!
This dish is one of my favorites because it’s the easiest fish foil recipe you can make! And even though it requires only 4 ingredients, this rainbow trout Recipe is very flavorful.
On top of that, this recipe will be ready from start to finish in less than 30 mins. This is definitely the best meal when life is extremely busy. Enjoy!
How To Store Leftovers
- Storage – Transfer leftover trout to an airtight glass container and keep in the refrigerator for 3-4 days. Or, portion them out into meal prep containers to have for lunches throughout the week.
- Reheating – For best results, heat in a pan on the stove so the trout stays crispy or broil it for 1-2 minutes in the oven. You can also heat in the microwave along with some sides for a full meal at once.
Ways To Use This Trout
If you have leftover trout and want to change things up, here’s some ways to enjoy the salmon:
- trout tacos: shred the trout up and serve it in a taco
- trout pasta: roughly chop up the trout and add it to a pasta
- trout salad: break up the salmon and toss it in a leafy salad or greek salad or salmon/trout salad.
- trout fried rice: break up the trout and toss it in some fried cauliflower rice.
- You can make trout meal-prep for your lunch week since trout stays go in the fridge for up 4 days.
If trout is not an easy fish to find in your area, you can replace it for different types of fish like Cod, Mahi Mahi or Salmon.
