Begin by preheating the oven to 425 degrees Fahrenheit
Next, line a baking sheet with aluminum foil and place the trout filets on top, skin side down
Drizzle each filet with 1 tablespoon of olive oil. Using a pastry brush or spoon, spread the oil evenly over each filet
Next, sprinkle the fish with desired seasonings such as salt, black pepper, and garlic powder
Next, slice 1 lemon, placing 1-2 slices on each filet of fish
Place the fish in the oven and let it bake for about 12-15 minutes
Check for doneness by using a food thermometer. The internal temperature of the fish should be 145 degrees Fahrenheit
Once cooked, carefully remove the filets from the baking sheet with a fish spatula
Discard the lemon slices and serve
If desired, cut some additional lemon wedges for serving, enjoy!
