How to tell when fish is cooked properly?
A properly cooked fish will be opaque in color and flake apart easily with a fork when ready.
The internal temperature for properly cooked fish and seafood is 145-degrees Fahrenheit.
Another way I've found to tell when fish is cooked properly is when a milky white substance (called the albumin) appears on the surface of the cooked fish.
Albumin is thickened protein exuded by cooking fish and is perfectly safe to eat.
Should the skin be removed from the fish?
It's a personal choice.
I did not remove the skin from the rainbow trout.
In case you're wondering, the skin of a rainbow trout is also perfectly safe to eat.
Can other vegetables be used in this recipe?
Sure, use your favorites, and feel free to omit any that I have used that perhaps you're not particularly fond of.
When preparing, just make sure to keep them on the smaller side when chopping so they'll cook in the same amount of time as the fish and the other vegetables on the tray.
What other fish can be used for this recipe?
I would suggest a fish with the same thickness as rainbow trout so the cooking time is similar to what is written in the recipe.
Salmon or tilapia would be a nice choice.
However, a thicker fish will also work (cod or mahi-mahi, for example). But be aware that the cooking time will be longer than what is written in the recipe, so keep an eye on the veggies so they don't burn.
Prep made easy:
If you'd like to cut down on the preparation time for making this sheet pan seafood supper, feel free to cut and prep the veggies in advance.
The chopped vegetables can be stored in the refrigerator (covered) for up to two days.
Of course, you can also purchase your vegetables of choice already chopped for convenience in the produce department. There is no shame in that.
However, depending on their pre-chopped size, you may still need to cut them down additionally, but the bulk of the work will have already been done for you, saving you time and energy.
How to make sheet pan fish with vegetables:
- Preheat oven to 400-degrees.
- Assemble the ingredients and chop the vegetables into like-size pieces.
- Add the vegetables to a large bowl and drizzle with olive oil.
- Add salt and pepper to the veggies, and toss well to coat.
- Drizzle additional olive oil onto a baking sheet and use a pastry brush to cover the entire surface.
- Place the fish onto the baking sheet and surround it with the prepared vegetables.
- Season the fish with salt, pepper, and dill weed, and top with lemon slices.
- Roast in the oven for 30 minutes, or until the fish is opaque and flaky and the vegetables are tender.
- Serve and enjoy!
