This baked haddock is perfectly flaky and delicious and cooked in the oven to perfection! Ready in less than 20 minutes, it’s perfect for a quick and healthy dinner.
When it comes to quick and healthy dinner recipes, I have a few favorites up my sleeve. I like making a chicken parmesan and of course, nothing beats some low calorie pizza. However, when I find fresh haddock at the grocery store, I love to whip up a simple baked haddock.
Why this baked haddock recipe will be a seafood favorite in your household-
- Ready in less than 20 minutes. From prep to plate, this entire recipe takes less than 20 minutes. No meal prepping needed.
- Healthy and low calorie. White fish, like haddock, is super low in calories but high in protein, making it a healthy and wholesome dinner idea.
- Made in just one dish! Skip multiple pans and bowls- everything is cooked up in one baking dish.
- No marinating required. Unlike other seafood or meat, there is no marination required beforehand.
What I love about this dish is just how simple and delicious it is. Haddock has an unfair stigma that it is a hard fish to cook, but this recipe proves otherwise. A secret tip guarantees perfectly flaky and tender fish every single time.
How to bake haddock?
- Haddock filets– Skinless filets that are all around the same size and weight, approximately 6 ounces/170 grams.
- Salt and pepper– To sprinkle over the fish before baking it.
- Olive oil– Flavorful and rich tasting, perfect for a simple baked fish.
- Cherry tomatoes– Also known as grape tomatoes. For a fun twist, use a mix of yellow, orange, and red ones.
- Lemon– Thinly sliced with their peel intact.
- Garlic– Sliced, not minced.
- Thyme– Several sprigs baked with the fish, to bring out the flavors.
Start by patting dry the fish filets, then season them with salt and pepper. Next, add all the remaining ingredients, except for the thyme, into a mixing bowl and mix until combined.
Now, add the tomato mixture into a 9 x 13-inch baking dish. Place the haddock filets on top and bake for 15-17 minutes, or until the fish is cooked and flaky. Remove them from the oven and serve immediately.
What temperature should haddock be cooked at?
Haddock, and/or any kinds of white fish, should always be cooked at 200C/400F in the oven. The higher than average heat allows the exterior to cook faster, which then filtrates throughout the rest of the fish, giving it the gorgeous, flaky texture.
Cooking haddock at a lower temperature risks the fish drying out and becoming slightly rubbery.
Tips to make the best recipe
- Push the tomato, lemon and garlic mixture to sit around the fish before baking, not under it.
- Do not add oil to the fish itself, as this can crisp up the sides too quickly.
- If you choose to use skin-on haddock filets, bake them skin side down.
Storing, freezing and reheating instructions
- To store: Leftovers can be stored in the refrigerator, covered. They should be eaten within three days.
- To freeze: Place the cooked and cooled fish in an airtight container and store it in the freezer for up to two months.
- Reheating: Microwave the fish for 30-40 seconds or reheat in a preheated oven.
