Rainbow trout is such a tasty fish with a wonderful yet mild flavor – it doesn’t need much enhancing at all, which makes it a very easy fish to cook.  To bring out the best flavor out of trout, I used very basic ingredients: olive oil, salt and pepper, minced garlic, and fresh lemon slices. That’s it! That’s all you really need to make the best rainbow trout!

The fish is baked on a sheet pan together with asparagus. This recipe makes a complete meal: you get the dinner (trout) and the side dish (asparagus) done at the same time.

What spices to use for cooking rainbow trout

There are lots of ways that you can enhance the flavor of trout with simple ingredients:

• Use basic ingredients, such as salt and pepper, minced garlic, and lemon slices.
• Dried and fresh herbs go great with rainbow trout. Use thyme, oregano, rosemary, parsley, or dill.
• Use dry rubs for fish. You can buy excellent dry rubs made specifically for fish in various stores, or you can make your own.

How to cook rainbow trout fillets in the oven

Rainbow trout fillets are usually quite large in size, which makes them well-suited for baking on a sheet pan in the oven!  Here is how to make baked rainbow trout:

1. Preheat oven to 400 F.
2. Line a rimmed small baking sheet (I used half sheet) with parchment paper.
3. Place trout fillet skin side down in center of the baking sheet. Brush 1.5 tablespoons of olive oil over the top of the trout.
4. Sprinkle salt and cracked black pepper over the trout.
5. Spread minced garlic over the trout fillet.
6. Top trout with lemon slices.
7. Bake for about 15 minutes at 400 F in the preheated oven until the trout fillet is cooked through.

Step-by-step photos for cooking the rainbow trout:

Place the trout fillet skin side down and asparagus on a parchment paper lined sheet pan:

Spread olive oil over the trout and the asparagus.  Sprinkle the fish and the vegetables with salt and black pepper. Add minced fresh garlic on top.

Add thinly sliced lemon.

Bake in the preheated oven at 400 F for about 15 minutes.

Remove lemon slices before serving, if you like.

What to serve with rainbow trout:

• Oven-roasted vegetables, such as asparagus, sliced bell peppers, red onions.
• Grilled vegetables, such as squash, zucchini, red onions, asparagus, or bell peppers.
• Potatoes. Serve mashed potatoes or oven-baked potatoes roasted with herbs and garlic in olive oil.
• Fresh green salad. Make a simple green salad by tossing together spinach, or arugula, or mixed salad greens with a small amount of olive oil and a splash of balsamic vinegar. Top the salad with shredded Parmesan cheese and a handful of nuts, such as cashew nuts, pine nuts, or toasted slivered almonds.
• Rice.  Jasmine rice is an excellent side dish choice for trout fish.  For more flavor, serve wild rice or flavored rice.
