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.

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.

This Rainbow Trout recipe 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 trout recipe is very flavorful.

Ingredients to make rainbow trout Recipe

  • 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 slicesbefore serving. Or you can also fresh lemon juice on the top of it.

    can you freeze this trout prior to cooking


    • Olivia says

      Yes you can.


  2. Benjamin Higginbotham Perez says

    Awesome 😎


  3. Ann says

    Cooking fish at 375 for 13 minutes is far too long even if wrapped in foil! The fish was totally dried out and tasteless.


    • Olivia says

      The time will depend on the thickness of the fish you have.


    • Jennifer Jensen says

      Hm interesting. We cooked it for 15 and it had zero dryness at ALL. This was the perfect recipe for us!! Thanks!


  4. Roxanne Marchese says

    This dish was amazing! I was shocked at the small amount of ingredients that were used and how awesome it came out. Everyone loved it and I will be serving this again soon. My fillets were relatively thin, so I baked approximately 10 minutes. I tend to tweak recipes, but this certainly did not require that!!! Thanks.


    • Olivia says

      I’m thrilled to hear you loved the dish! It’s fantastic that it turned out so well with just a few ingredients. Your tip about adjusting the baking time for thinner fillets is helpful, and I appreciate you not needing to tweak the recipe. Thank you for sharing your positive experience, and I hope it becomes a regular favorite for you! 🌟 Happy cooking!
