How to Cook Rainbow Trout Fillet and for How Long?

Cooking rainbow trout fillets in the oven is easy. Rainbow trout has a mild flavor so all you'll need to make this delicious dish are a few simple ingredients.

Here's an overview of the ingredients you'll need to make this light meal. Amounts are in the recipe card at the end of this post.

Ingredients Overview:

  • Rainbow trout fillet
  • Asparagus: Choosing pencil thin asparagus will ensure they cook quickly.
  • Zucchini 
  • Cherry or grape tomatoes
  • Lemon slices
  • Extra-virgin olive oil
  • Fresh herbs such as thyme and oregano: Dry can be substituted if fresh isn't available
  • Salt and freshly ground black pepper

Steps Overview:

Start by preheating your oven to 425°F.

If you are cooking the trout on its own, you can wrap it in foil or parchment paper to keep it moist. When cooking it with vegetables simply line the baking tray with aluminum foil or parchment paper.

The asparagus actually takes about 5 minutes longer to cook than the trout does, so when getting your meal ready start with the asparagus.

Prepare and bake the asparagus in the oven for 5 minutes before adding the rest of the vegetables and rainbow trout, placed skin side down on paper, to the baking sheet. Put the tray back in the oven and in just about 10 minutes you will have perfectly cooked trout and veggies!

To make sure I don't overcook the trout fillets, I like to check on them after 10 minutes of cooking time, especially if the fillets are thinner and on the small side.

You can tell if the trout is properly cooked when the fish flakes easily at the thickest part (use a fork or knife to check). If the trout doesn't flake easily, return it to the oven and bake for a few more minutes before checking again.

Serving Suggestions

Options for side dishes that cook or can be prepared quickly include whole-wheat couscous, which actually takes less than ten minutes to cook. I like to sprinkle some chopped pistachios onto the couscous just before serving.

You can also serve it with a simple rice dish or a side of orzo tossed in a pre-made pesto.

My favorite salads to serve with this rainbow trout are:

And if you're watching your carb intake you can simply serve it with a veggie salad or steamed vegetables.

Storage Instructions

Store any trout dinner leftovers in an airtight container and refrigerate for up to 4 days.

Enjoy!

My parchment paper box says that it is not safe to use parchment paper in oven over 425

Hello Dan,

The recipe suggests baking the fish at 425F so you should be fine with parchment paper but if this worries you, simply line the baking sheet with aluminum foil or rub a little bit of oil on your sheet so the fish doesn't stick.
