Rainbow trout is a popular freshwater fish that is low in fat and high in protein and omega-3 fatty acids. Not only is it healthy to eat, but it is also quite versatile and can be prepared in many delicious ways. Here are some tried and true methods for cooking rainbow trout fillets.

1. How to Cook Rainbow Trout Fillets in Oven


  • 2 rainbow trout fillets (5-6 oz each)
  • 2 tbsp lemon juice
  • 1 tsp fresh dill
  • 1/4 tsp salt
  • 1/4 tsp pepper
  • 2 lemon slices


Preheat oven to 400°F.

Cut two 12-inch pieces of foil and place a fillet in the center of each. Sprinkle fillets with lemon juice, dill, salt, and pepper.

Top each with a lemon slice. Fold foil around fillets and crimp edges to seal well.

Place packets on a baking sheet and bake for 15-18 minutes until fillets flake easily with a fork.

Serve with the packets open.

2. How To Cook Whole Rainbow Trout Fillets on Grill


  • 2 rainbow trout fillets
  • 2 tablespoons olive oil
  • 2 cloves garlic, minced
  • 1 tablespoon fresh lemon juice
  • Salt and pepper to taste
  • Fresh herbs (such as dill, parsley, or thyme) for garnish
  • Lemon wedges for serving


Preheat your grill to medium-high heat.

Rinse the rainbow trout fillets under cold water and pat them dry with paper towels.

In a small bowl, whisk together the olive oil, minced garlic, lemon juice, salt, and pepper. This will be your marinade.

Place the rainbow trout fillets in a shallow dish or a resealable plastic bag. Pour the marinade over the fillets, making sure they are evenly coated. Allow the fish to marinate for about 15-30 minutes at room temperature.

Once the grill is preheated, lightly oil the grates to prevent the fish from sticking. You can use a brush or a folded paper towel dipped in oil for this.

Remove the rainbow trout fillets from the marinade, allowing any excess marinade to drip off. Place the fillets directly on the preheated grill, skin side down.

Grill the trout fillets for about 4-5 minutes per side, depending on the thickness of the fillets. Avoid overcooking, as trout can become dry.

While grilling, you can brush the fillets with the remaining marinade to enhance the flavor and keep them moist.

Once the trout is cooked through and flakes easily with a fork, remove it from the grill. Be careful not to break the fillets while handling.

Garnish the grilled rainbow trout with fresh herbs, such as dill, parsley, or thyme. Serve with lemon wedges on the side for squeezing over the fish.

Enjoy your grilled rainbow trout as a main dish, alongside a fresh salad or your favorite side dishes!

Note: Grilling times may vary depending on the thickness of the trout fillets, so it’s always a good idea to keep an eye on them while cooking.

3. How To Cook Rainbow Trout Fillets On Stove


  • 2 rainbow trout fillets (5-6 oz each), skin on
  • Salt and pepper to taste
  • 2 tbsp olive oil


First, generously season the skin side of the fillets with salt and pepper then heat a non-stick skillet over medium-high and add 2 tbsp olive oil

Gently lay the fillets skin side down in the hot pan. Resist the urge to move them for 4-5 minutes, allowing the skin to brown and crisp.

Once browned, use a spatula to carefully flip the fillets. Cook the second side for only 2-3 minutes until the flesh becomes opaque and flakes easily.

The skin side should be a deep golden brown. Transfer cooked fillets to a platter and enjoy while still hot and crispy. Any pan drippings pair well with new potatoes or risotto.

4. How To Cook Rainbow Trout fillets in Air Fryer


  • 2 rainbow trout fillets (5-6 oz each)
  • 2 tsp olive oil
  • Salt and pepper to taste
  • 1 tsp fresh dill
  • Lemon wedges


Pat fillets dry and brush or spray both sides lightly with oil. Generously season fillets all over with salt, pepper, and fresh dill.

Place the fillets in the air fryer basket in a single layer. No need to overcrowd them.

Set the temperature to 375°F and set the timer for 8-10 minutes. Halfway through cooking, open the fryer and flip each fillet over for even cooking.

The fillets are done when they turn opaque and flakes apart with gentle pressure. Serve immediately with lemon wedges or a creamy sauce or vegetable.

Air frying creates a crispy exterior without using excess oil. It’s a healthy way to enjoy rainbow trout anytime.

In summary, rainbow trout can be prepared in many ways that highlight its delicate flavor, from simple baked fillets to pan-seared or grilled whole fish. Whether using the oven, stovetop, grill or air fryer, these recipes provide tasty options for cooking this versatile freshwater fish.
