Even though I love to cook and would be happy to spend all day in the kitchen, the reality is life's too busy for that. I need delicious and healthy meal options that can be prepared in just about 30 minutes. Seafood is a great option for getting nutritious meals on the table quickly.

Best Rainbow Trout Recipe

This Baked Rainbow Trout Fillet with a side of veggies is an easy recipe that can be baked in the oven. This dish is healthy, light, flavourful and simple to make.

What's even better about this meal is that you can cook the fish and a side of vegetables all on the same baking sheet in the oven. It's perfect for those days when you don't have much time to cook.

How to Cook Rainbow Trout Fillet and for How Long?

Cooking rainbow trout fillets in the oven is easy. 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 foil or parchment paper.

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.

What to Serve with Rainbow Trout Fillet?

In this recipe, I use asparagus, cherry tomatoes and zucchini to bake with the rainbow trout fillet. 

The asparagus actually takes about 5 minutes longer to cook than the trout does, so when getting your meal ready start with the asparagus. Choosing pencil-thin asparagus will ensure they cook more quickly. 

Prepare the asparagus and bake them in the oven for 5 minutes before adding the rest of the vegetables and rainbow fish to the baking tray. Put the tray back in the oven and in just about 10 minutes you will have perfectly cooked trout and veggies!

More Side Options

Additional options for sides 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 small side of orzo tossed in a pre-made pesto. 

My favorite make ahead side dishes to serve with this rainbow trout are this Mediterranean Pasta Salad and this Southwestern Quinoa Salad.

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

Enjoy!

  • Return the baking sheet to the oven and cook for another 10 minutes or until the fish flakes easily with a fork.

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.
