At Sweet C’s, I add lots of tips in all of my recipes – because I am a home cook without any formal training, and I find I am more confident making dishes when I understand why it works, and what each ingredient means to the flavor of a recipe – my goal is for even the most beginner home cook to feel empowered in the kitchen.
I want each reader to walk away with a solid knowledge of each recipe, with all of the tips I’ve gathered from extensive testing of each recipe. I also answer questions my friends and family have asked about my recipes, to help everyone better understand the processes we use – and why!
Table of contents
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.

That’s the Best recipe!!
Thank You!! ?
I don’t usually write reviews, but this was fantastic. So easy, healthy and yummy! Will def make again.
Loved it with sole fillets, fire-roasted tomatoes seasoned with dried oregano & basil, enhanced with fresh basil leaves (torn). Because the fish was boneless and under one pound, cooked for only about 10 minutes, checking after 8. Delicious and healthy.
This time, I added a small can of baby artichokes. Yum!
I am going to try this one tonight!
This is so easy. I’ve made it a few times. Also doctoring it up a bit as I go. I like to add white wine sometimes, possibly some cream or brown butter the sauce and serve over angel hair or polenta. Nonetheless, tomatoes, fish and capers are about as versatile as you can get
i loved this so much the first time I made it a few weeks ago, I had to make it again tonight.
I can’t say that I bake fish enough – but after seeing this post you definitely have motivated me to do so. This one pot tuscan baked fish looks divine and I can imagine how rich and flavoursome it is!
