Ingredients You’ll Need

You don’t need much to make this dish shine, just fresh haddock, a few citrus notes, and a handful of everyday herbs and butter. Here’s everything you’ll need to bring this light, flavorful meal together:

For the Sous Vide Haddock

• 2 haddock fillets (about 6 ounces each) – Choose fresh, boneless fillets with a clean, ocean-fresh scent.
• Salt and freshly ground black pepper – Enhances the natural sweetness of haddock.
• 1 tablespoon olive oil – Helps keep the fillets moist in the sous vide bag.
• 2 lemon slices – Optional, but they infuse a gentle aroma while cooking.

For the Citrus Herb Sauce

• 2 tablespoons unsalted butter – Adds richness and silkiness to the sauce.
• 1 tablespoon olive oil – Keeps the butter from browning too quickly and balances the flavor.
• 2 cloves garlic, minced – Provides a subtle savory base.
• Zest and juice of 1 lemon – Bright and tangy, this forms the heart of the sauce.
• Zest of ½ orange – Adds a soft sweetness that pairs perfectly with white fish.
• 2 tablespoons finely chopped fresh parsley – Brings freshness and color to the dish.
• 1 teaspoon Dijon mustard – Helps emulsify the sauce and adds a mild tang.
• Salt and pepper, to taste – Adjust to your preference for balance and depth.

Optional Garnish

• Lemon wedges – For a final squeeze of brightness.
• Fresh dill or extra parsley sprigs – To finish with a touch of green and aroma.

Pro Tip: If you can, use freshly grated zest instead of bottled juice, it makes all the difference in capturing that clean, sunlit flavor.

Step-by-Step Instructions

Here’s how to make Sous Vide Haddock with Citrus Herb Sauce from start to finish, calm, simple, and absolutely delicious.

Step 1: Preheat the Sous Vide Water Bath

Fill your sous vide container or a large pot with water and set the temperature to 130°F (54°C).
This is the sweet spot for haddock, it keeps the fish tender, flaky, and moist without falling apart. While the water heats, prepare your fish.

Step 2: Season the Haddock

Pat the haddock fillets dry with paper towels to remove any excess moisture.
Season both sides generously with salt and freshly ground black pepper, then drizzle lightly with olive oil.
If you like a hint of citrus in every bite, tuck a thin lemon slice beside each fillet before sealing.

Step 3: Seal the Fish

Transfer each seasoned haddock fillet into a vacuum-seal bag or a heavy-duty zip-top bag.

If working with a zip-top bag, employ the water displacement method: gradually submerge the open bag into the water bath to release trapped air, then secure the seal just before the top reaches the waterline. This guarantees even cooking and prevents floating.

Step 4: Cook the Haddock

Once the water reaches 130°F, gently lower the sealed bags into the water bath.
Cook for 35 to 40 minutes, long enough to let the fish cook through but stay buttery and tender.
During this time, the haddock will absorb gentle heat evenly from edge to center, locking in moisture beautifully.

Step 5: Prepare the Citrus Herb Sauce

About 10 minutes before the haddock is done, melt 2 tablespoons of butter with 1 tablespoon olive oil in a small saucepan over medium heat.
Add the minced garlic and cook just until fragrant, about 30 seconds.
Whisk in the lemon juice, lemon zest, orange zest, Dijon mustard, and parsley.
Season with salt and pepper to taste. Keep the sauce warm on the lowest heat setting while the haddock finishes.

Step 6: Finish and Serve

Carefully remove the bags from the water bath and open them gently, the fish will be very tender.
Transfer each fillet to a plate and pat dry lightly with paper towels.
Spoon the warm citrus herb sauce generously over the top.
Garnish with a sprinkle of fresh parsley or dill and a squeeze of lemon.

Did you know? Sous vide means “under vacuum” in French, a method that gives you the same silky texture top chefs achieve, without needing a restaurant kitchen.

Chef’s Tips

A few small tweaks can turn this Sous Vide Haddock with Citrus Herb Sauce from good to unforgettable. Here’s how to make every bite shine:

• Mind the Temperature – Keep your sous vide bath steady at 130°F (54°C) for flaky, tender results. Going higher can make the fish dry and chalky.
• Use Fresh Citrus – Bottled juice just can’t compete with the brightness of fresh lemon and orange zest. Always zest before juicing, it’s easier and captures more of the essential oils.
• Season Lightly Before Cooking – Since sous vide locks in flavor, a little salt goes a long way. You can always finish with a sprinkle of flaky sea salt at the end for texture.
• Sauce Balance – If your sauce tastes too tart, stir in an extra teaspoon of butter to round out the acidity. Too mild? Add a small pinch of lemon zest for a fresh kick.
• Don’t Skip the Rest – Let the haddock rest for 1–2 minutes after removing it from the bag. This helps redistribute moisture and gives a more consistent texture.

Fast Fact: Haddock is naturally rich in B vitamins and omega-3s, great for heart health and energy without weighing you down.
