One Pot 5 Ingredient Tuscan Baked Fish - a super simple and crazy delicious baked fish recipe that is bursting with flavor and perfect for picky eaters!

We love to eat fish in our house- but we don't really eat enough fish to come up with a bunch of delicious, easy, go-to dishes that our whole family loves.
We usually do an easy lemon/garlic baked fish dish that is pretty easy to throw together, or blackened fish tacos- but we've been trying to start adding to more of our go-to's as we try to incorporate more lean proteins into our diet.
While my husband and I like a wide variety of fish preparations, my kids most certainly do not.
They are pretty picky and don't like "fishy" flavors or smells.
This 5 Ingredient Tuscan Baked Fish is a delicious, quick and easy meal that our whole family loves - and we bake it so you don't need to worry about fishy smells, this is one dish even picky eaters love!
We hope you love this recipe as much as we do.

Easy Tuscan-Style Sauce
This dish, while being one-pot, is actually two different methods.
You're first going to make a sauce and soften the onions, and then pop the whole thing in the oven with the fish.
Don't rush the sauce - let onions soften and lightly brown to draw out as much flavor as possible without adding tons of other ingredients.
What Pan To Bake Fish In
Because we're finishing the dish in the oven, it is imperative that you use an oven-proof pan, and please be careful when removing the pan from the oven.
I can't tell you how many times my husband and I space that the pan is in the oven and go to grab it without a pot holder- its such a stupid thing to do, but we've sadly done it more than once!
How Long To Bake Fish
One important note- the cooking times listed for baking the fish in here might be way off, depending on the size and shape of your fish filets.
This application is great for so many types of fish- but that means it might take longer or shorter time in the oven to cook.

When is Fish Cooked
Check your fish by pulling at the largest end with a fork- if it looks white and flaky inside, it is done.
If it is still a bit purple/translucent, it has a bit longer to be cooked through.
Some people prefer undercooked fish- but as I'm in a thoroughly landlocked state and make this dish with cheaper frozen filets, I prefer to take mine all the way.
What to Serve With Tuscan Baked Fish
This baked fish is great paired alongside easy roasted vegetables, including our whole roasted cauliflower, 10 minute broccolini, sauteed zucchini and squash, and Air fryer french fries.

Hey Thomas, I'm so sorry - sometimes my spam filter catches comments that aren't spam, I bet that might have happened!
