I love how simple and tasty this baked haddock recipe is. It’s one of those dishes that feels special but doesn’t take forever to make. I think you’ll enjoy how the flavors come together with just a few ingredients.
Most of the ingredients for this recipe are easy to find in your kitchen or local store. If you don’t usually keep paprika or garlic powder around, those are the only spices you might want to pick up. Fresh lemon is also important because it adds a bright, fresh flavor that really makes the fish pop.

Ingredients For Baked Haddock Recipe
Haddock fillets: The main ingredient, haddock is a mild white fish that flakes nicely when cooked.
Olive oil: Adds moisture and helps the spices stick to the fish.
Garlic powder: Gives a gentle garlic flavor without the sharpness of fresh garlic.
Paprika: Adds a smoky, slightly sweet taste and a nice color.
Salt: Enhances all the other flavors.
Black pepper: Adds a little bit of heat and depth.
Lemon: Fresh lemon slices add brightness and a bit of tang to the dish.
Technique Tip for This Recipe
One of the most helpful moves in this Baked Haddock Recipe is how you sprinkle the seasonings over the fish. It might seem simple, but doing it right makes a big difference in how tasty and evenly flavored your fish turns out. Here’s a quick way to do it:
- Hold your hand a little higher above the fillets—about 6 to 8 inches up. This helps spread the spices more evenly instead of clumping in one spot.
- Sprinkle a little at a time, moving your hand back and forth across the fish.
- Try to cover every part of the fillet with the garlic powder, paprika, salt, and black pepper so each bite has flavor.
- If you miss a spot, just add a tiny pinch more there.
Doing this makes sure the haddock cooks with a balanced taste all over, not just in some bites. It also helps the olive oil stick better to the fish and the lemon slices on top, which adds a fresh zing.
When I first tried this recipe, I used to sprinkle the spices too close to the fish, and the flavor was patchy. Now, I like to imagine I’m gently dusting the fillets like a light snow, and it turns out much better. Plus, it’s kind of fun! If you’re in a hurry, you can mix all the spices together in a small bowl first, then sprinkle the mix all at once—that saves a bit of time and still tastes great.

How to Store or Freeze This Dish
Allow the haddock to cool completely at room temperature before storing. This prevents condensation, which can make the fish soggy.
For short-term storage, place the baked haddock in an airtight container. If you have multiple fillets, layer them with parchment paper to avoid sticking.
Store the container in the refrigerator. The haddock will remain fresh for up to 3 days, retaining its delightful flavors and texture.
For longer storage, consider freezing. Wrap each haddock fillet individually in plastic wrap or aluminum foil to protect against freezer burn.
Place the wrapped fillets in a freezer-safe bag or container. Label with the date to keep track of freshness.
The baked haddock can be frozen for up to 3 months. When ready to enjoy, thaw overnight in the refrigerator for the best texture.
To reheat, preheat your oven to 350°f (175°c). Place the haddock on a baking sheet and cover with foil to retain moisture. Heat for about 10-15 minutes or until warmed through.
For a quick reheat, use the microwave. Place the haddock on a microwave-safe plate, cover with a damp paper towel, and heat in 30-second intervals until hot.

How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover baked haddock in an oven-safe dish. Cover it loosely with aluminum foil to prevent it from drying out. Heat for about 10-15 minutes or until warmed through. This method helps maintain the fish's moisture and flavor.

If you have an air fryer, preheat it to 320°F (160°C). Place the haddock fillets in the basket, ensuring they don't overlap. Heat for about 4-5 minutes. This method can help retain a bit of crispiness on the outside while keeping the inside tender.
For a stovetop method, heat a non-stick skillet over medium heat. Add a small amount of olive oil or butter. Place the haddock fillets in the skillet and cover with a lid. Heat for 3-4 minutes, flipping halfway through. This method can enhance the flavors with a slight sear.
