This rainbow trout baked in foil is such a great recipe for any night of the week. It is quick to make and assemble and perfect if you’re after a very low-effort but high-impact meal. In fact, from start to finish, you really don’t need more than thirty minutes to complete this dish – and that is being generous!

One of the great things about this preparation of fish is that the majority of the cooking time is inactive, meaning that you can whip up a great side dish during that time – my sautéed kale and chard is a great choice, as are my roasted sweet potatoes!

So if you’re after a super simple dinner recipe, then this spiced rainbow trout is sure to be a huge hit!

How to Cook Trout Fillets in Foil

This is such a quick and easy recipe, it’s sure to be something that makes it into your regular dinner rotation. It also follows a very similar process as in my red snapper recipe!

The first step is to season the trout generously with salt and pepper. This is absolutely essential to ensuring you have a flavourful fish at the end. Then, transfer your fish to a large piece of aluminium foil.

Next, combine some smoked paprika and cumin in a small bowl. I really like the flavour combination between these two spices, but if you don’t have one or the other, don’t worry about it.

It will be great with just cumin or just smoked paprika. It will also be tasty if you have sweet paprika rather than smoked!

To the spices, grate in a clove of garlic and pour over a bit of extra virgin olive oil. Stir until it’s thoroughly combined.

Mixing the spices with the oil will ensure that their flavours bloom while the fish is cooking and results in a more robustly flavoured final result than if you just sprinkled the dry spices over the fish.

Then, evenly spread the spiced oil over the fish fillet, ensuring the entire fillet is covered with the mixture.

After covering the fish with the spice mixture, all you need to do is cover it with some lemon slices.

I like to ensure that the entire fish is covered with the lemon to make sure that everything gets evenly flavoured.

Next, simply crimp the foil tightly all around the trout fillet. Move the foil packet onto a baking sheet and then transfer to a preheated 180°C/350°F oven.

Cook the trout for about fifteen minutes, or until an instant-read thermometer registers 50°C/125°F when it’s inserted to the thickest part of the fish.

It is far better to gauge doneness by using a thermometer rather than time as fillets can vary in thickness, which impacts the cook time.

You can temp the fish my piercing right through the foil – no need to un-crimp it!

Once your trout is done, remove it from the oven and allow it to rest in the foil for about five minutes. Then un-crimp the foil and remove the lemon slices.

Serve the fish alongside any dish you choose, with a couple of lemon wedges to squeeze over it should you wish! This is also a quicker alternative to my baked salmon recipe, but no less delicious.

Notes

If possible, rely on the internal temperature of the fish rather than the cook time. As thicknesses of trout fillets can vary, so can cooking times, so the fifteen minutes listed in the recipe is merely a guideline.
