Baked Haddock with roasted tomatoes, fennel and shallots- a simple, easy, healthy one-pot meal that can be made in 35 minutes! Gluten-free, Paleo, keto!
Here’s an easy delicious recipe for Baked Haddock with Roasted Tomatoes and Fennel. It’s a healthy “one-pot” meal that can be made with any white fish really ( cod, halibut, seabass, sablefish) and the roasted fennel with summer tomatoes, garlic, lemon and thyme is one of my favorite combinations.
Haddock, if unfamiliar is a popular whitefish on the East Coast, known for its flaky clean texture, and low oil content, very similar to Atlantic cod. A family owned seafood company, Mazzetta Company sent me some of their Haddock to try, and it was fun experimenting with it, never having it before. Typically on the East Coast, it’s served “New England Style” with a breading of sorts, but I thought I put more of a Northwest spin on it this time.
The tomatoes and fennel become meltingly delicious in the oven, then the fish is nestled in them, and baked.
In this recipe, I cut the haddock into smaller pieces, and marinated it in a mixture of olive oil, garlic, lemon and thyme.
While the fish is marinated, begin layering the onion, thinly sliced fennel and tomatoes.
Drizzle with olive oil, salt and pepper and roast in the oven until the fennel is tender, about 30 minutes.
Put it out of the oven and nestle the fish in the roasted tomatoes fennel mix, and place back into the oven for 7-9 minutes, or until the fish is cooked to your liking.
When it comes out of the oven, squeeze with lemon and serve.

Thanks Jesse!
Saw this recipe and went to the grocery store right away. Cooked this tonight and it’s my new favorite dish that I cook! I used cod filets and added jalapeños to the veggie mixture because I enjoy some heat. Also added slices of butter when I added the fish in to make it more keto friendly. Absolutely the best baked fish I’ve had! Thanks so much for sharing!
