These easy oven baked trout fillets are the perfect weeknight dinner. If you’re not sure how to cook melt-in-your-mouth trout, this is the answer! With Dijon mustard, dried herbs and garlic, this will quickly become a favourite.

I spend a lot of time thinking about what to cook for dinner. I think most people do. Once 3pm hits, you’d hear “What are you going to make for dinner?” ring through the office. It’s a daily struggle.

Enter seafood; salmon, trout or shrimp. Three super delicious ingredients that cook extremely fast. In the summer I like to grill salmon in foil, on extra busy nights I make a quick shrimp stir fry, and when the weather starts to cool down, I bake some trout or salmon fillets.

Enter this trout recipe. It’s the perfect weeknight meal to have in your back pocket–I’ve also used this marinade on salmon with much success.

Not only do we want something that tastes delicious, we also want something that’s easy. These two things don’t always go hand in hand. But that’s my mission, to create recipes that are worthy of a social media share and a Monday night.

I typically cook with more salmon than I do trout, but since we’re eating at home so often these days, I’ve been trying to find ways to change things up.

The best trout marinade

Not only do fish fillets cook really quickly, they also don’t need a long marinate time. The general rule when it comes to marinating seafood is 30 minutes max. For this marinade, I do a simple combination of olive oil, Dijon mustard, garlic, dried oregano, salt and chili flakes.

I typically brush the trout with the marinade before I start prepping my side dishes. I like to serve this with a kale salad along with roasted vegetables.

Serving the fillets with lemon wedges is the perfect way to finish the dish. I find that sprinkling the lemon juice on after the fish has cooked brightens up the dish with a hit of acidity–that’s why I’ve left lemon out of the marinade.

How long should you bake trout in the oven?

It depends if you’re cooking a whole trout, full fillets, or portioned fillets like in this recipe. Sometimes I like to cut mine into fillets before roasting because it make serving a little bit simpler.

For this recipe I’m using two rainbow trout fillets which are about 250g each which I’ve cut in half. They take about 10-12 minutes to cook at 400F.

    Having bought trout fillets for the first time, I was a bit stumped as I usually only cook whole rainbow trout. I found this recipe tonight and gave it a shot. These were the most delightful pieces of fish I’ve had in a while so I had to come back to thank you. Both my husband and I enjoyed them so much! Will be doing this again soon I’m sure!

    Made this for the first time this evening. It's nice, but as there's a lot going on there - mustard, chili, oregano etc - I felt it had too many flavours for a richly flavoured fish like trout. I intend to do it again, but with a meaty white fish such as halibut or monkfish. It would overpower something like sole, I feel My wife, however, thought it was fabulous and would give it the full five stars.

    Joined WW for the first time and have been cooking a lot of new recipes. Found this, and absolutely the best fish recipe I've done. The marinade was fantastic. My husband cooked this one, I would have used less salt (only add the bare minimum) and less oil to bring my points down. We will definitely be doing this one again ... and again!

    First time making Trout. This recipe was delicious. Smelled like I was cooking Italian food. So much great flavor. I will definitely make again and again. I may use 1/2 tsp less Dijon mustard since I’m not a huge fan. Dijon mustard is a must though. Thank you !!!
