I'm really happy to be sharing this rainbow trout recipe with you. One of the most popular recipes on this blog is this baked rainbow trout dish. Just like that rainbow trout dinner, this one is also quick and easy to make, gluten-free, healthy, low-carb and really delicious!

I'm always looking for different ways I can serve rainbow trout. One-pan meals that can be prepared and cooked in 30 minutes are great for weeknights and super busy weekends and this sheet pan trout doesn't disappoint.

Are Salmon and Rainbow Trout the Same?

The pink flesh of rainbow trout can easily be mistaken for salmon, and though trout and salmon do belong to the same fish family, rainbow trout can vary in colour from ivory to pink.

Rainbow trout is milder in flavor than salmon, but if you prefer salmon you can easily use it in place of rainbow trout in most recipes.

Rainbow trout is high in protein and low in calories which makes it an ideal fish when looking for a quick and healthy meal. I like the convenience of rainbow trout fillets. Purchasing them already filleted and depined (deboned) saves time and makes it easier and safer when serving it to children. 

How to Bake Trout Fillets in the Oven?

Baking rainbow trout fillets in the oven is easy. If you are worried about keeping the fish moist you could wrap it in foil or parchment paper, but as long as you don't forget to check on the fish there is no need for wrapping it.

I always set the oven timer on for 10 minutes, this way I don't forget to check the fillets. Ten minutes is often enough time, especially if the fillets are on the thinner side.

To ensure the fish is cooked thoroughly, just use a fork to flake the thickest part of it. If it flakes easily it's cooked, if not, return it to the oven and bake for 2 to 3 minutes longer before checking again.

How to Make Fish and Broccoli

Preparing this trout fillets recipe with broccoli couldn't be easier. Here is an overview of the ingredients you'll need to make this baked trout dish. You can find the full recipe in the recipe card at the end of this post.

Using Frozen Fillets

If you are using frozen trout fillets to make this recipe you will need to thaw them overnight in the refrigerator before cooking them.

You could cook the fish from frozen but it will take longer to do so and I have not tried it to see if the timing works with the broccoli cooking along side it. if you do give it a try, let me know in the comments below!

Ingredients Overview

For the Roasted Broccoli:

• Broccoli florets
• Olive oil
• Salt and pepper to taste

For the Rainbow Trout Fillets:

• Two rainbow trout fillets (approx 250g. each)
• Olive oil
• Salt and black pepper
• Chili pepper flakes (optional)
• Fresh parsley (optional)

Steps Overview

The seasoning for this rainbow trout recipe is simple. A little bit of olive oil, salt and pepper is all that's needed really. If you're not serving the fish with the tahini sauce then you could rub a bit of garlic (crushed into a paste) on the fillets.

1. Pat the trout fillets dry with paper towels and rub the flesh with olive oil, add a sprinkle of salt and freshly ground pepper. Set aside.
2. To prepare the broccoli, rinse it and drain it from water. Onto the baking sheet add the broccoli, olive oil, salt and freshly ground pepper. Toss the broccoli with the oil and the seasonings and spread out on baking sheet. 
3. Bake for 10 minutes, stir the broccoli and push it to one side of the pan. Add the seasoned trout fillets and top with a few fresh lemon slices and parsley sprigs (or thyme) next to the broccoli.
4. Cook until the trout fillets flakes easily with a fork, this will take approximately 10 minutes, depending on the thickness of the fillets. The broccoli and fish should be ready at the same time.

Pan Frying Trout

If you prefer to pan fry the trout, you can take a look at this Pan Fried Rainbow Trout recipe to see how you can do so. If you enjoy crispier skin on fish, pan frying the trout with its skin on will make it crispy.

How to Make Tahini Sauce

I like to serve this fish and broccoli dish with tahini sauce. But you can simply serve it with fresh lemon wedges.

If you didn't already know, tahini is a paste made from ground sesame seeds used in Middle Eastern cuisine. Tahini sauce can be served alongside a variety of dishes such as shawarma, falafel, roasted vegetables and fish. You should be able to find jars of tahini (which is naturally gluten-free) in most large grocery stores.

While the fish is in the oven you can prepare the tahini sauce. All it takes are a few simple ingredients:

• tahini paste
• garlic cloves
• freshly squeezed lemon juice
• salt
• water

To make this in your blender, simply add the all of the ingredients together to the jar and blend to get a silky tahini sauce. If mixing by hand, you'll need to smash the garlic into a paste, then add the garlic and the remaining ingredients into a bowl and whisk to combine.

This recipe makes a lot of tahini sauce. You can cut the ingredient amounts in half if you prefer smaller amounts. I like to make extra because it can also be used as a dressing on salads.

What to Serve with Trout?

One of the reasons I like rainbow trout so much is that its mild-tasting nature makes it perfect for pairing with a variety of vegetables, herbs, spices and sauces. Some of my favorite vegetables to serve with rainbow trout are broccoli, cauliflower, asparagus and zucchini.

These Roasted Grape Tomatoes take no more than five minutes to prepare and can be baked at the same time as the trout. You can also serve rainbow trout with a delicious side salad such as this Tabbouleh, Fattoush or this Mediterranean Pasta Salad.

Storage Instructions

Leftover cooked trout can be stored in an airtight container in the refrigerator for up to a maximum of four days. You can also freeze leftover trout for up to three months. Make sure to wrap it well with plastic wrap of aluminum foil and place it in a food storage freezer bag to protect it from freezer burn.

I hope you give this fish and broccoli a try, it's a favorite of mine and I hope you'll enjoy it as well!
