For Trout:

1.5 pounds of steelhead trout

3 tablespoons Dijon mustard

4 tablespoons everything bagel seasoning

For Service:

1/4 small red onion, sliced thin

1 small English cucumber 

1 cup cherry tomatoes, halved

1/2 cup fresh dill

1 lemon

3 tablespoons olive oil

Kosher salt and black pepper, to taste

1 cup tzatziki (homemade or store bought)

Sourdough toast


  1. Preheat oven to 350℉. Lay a sheet of foil over a baking pan. Dry the fish fillets with paper towels and place trout on foil.
  2. Brush Dijon mustard over the flesh side of the fish. Sprinkle liberally with bagel seasoning. Use a second sheet of foil to create an airtight packet, rolling the sides of the foil to close. Transfer the sheet pan with the foil packet to the oven and bake for about 12 minutes. 
  3. While fish is baking, slice cucumber, tomato and onion. Top with olive oil, juice of half of the lemon, and salt and pepper to taste.
  4. After 12 minutes, remove baking sheet of trout from the oven and carefully open the foil packet (watch out for steam!) Discard top piece of foil and return fish to oven for 6-8 minutes, or until trout reaches desired temperature (145℉ is well done). Remove from oven. The fish will be tender and juicy with a crunchy, slightly browned top. 
  5. To serve, spread half of your serving platter with tzatziki sauce. Scoop chunks of the trout onto the serving plate. Top with tomato salad and fresh dill. Serve with lemon slices and sourdough toast. 


Use Atlantic salmon, sockeye salmon or arctic char in place of steelhead trout, if you like. If using sockeye salmon, remember that it contains less fat and will cook more quickly, so reduce cooking time.

For this recipe, we serve the fish with a simple cucumber tomato salad, store-bought tzatziki and fresh dill. We toasted big slices of sourdough and built toasts with all the toppings. But this fish is equally delicious with Roasted Potatoes with Whipped Feta or served over Mediterranean Basmati rice.

This baked fish in foil is ideal for meal prepping. Easy to prepare and full of flavor, it's also versatile. Heat it gently and serve on toasts as in the recipe card, or with your favorite side dishes. It can also be served cold on salads, sandwiches, wraps or grain bowls.
