• Salt – Use kosher salt for optimal seasoning, but cut back if you’re using table salt.
• Black Pepper – Adds just the right amount of mild heat; adjust based on your spice preference.

Step‑by‑Step Instructions for Butter-Baked Haddock
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This temperature is perfect for baking the haddock, ensuring a tender and flaky texture. While the oven heats, gather your baking dish and other ingredients to prepare for an effortless cooking experience.
Step 2: Prepare the Fish
Pat the haddock fillets dry using paper towels, which helps to ensure a nice sear and enhances the buttery flavor. Next, place the fillets in a single layer in a lightly greased baking dish, ensuring they have enough space for even cooking and check for any lingering bones.
Step 3: Add the Butter
Now, pour the melted butter evenly over the haddock fillets. The richness of the melted butter is key to the Butter-Baked Haddock’s flavor and moisture. Make sure to cover each piece thoroughly for optimal taste, allowing the butter to soak in as it bakes.
Step 4: Squeeze Lemon Juice
Squeeze fresh lemon juice over the fish, aiming for about ½ teaspoon per fillet. This zesty splash adds a lovely brightness to your Butter-Baked Haddock. If you’re using bottled lemon juice, adjust to your preference, ensuring the fish is evenly coated for that refreshing zing.
Step 5: Season the Fillets
Sprinkle the haddock with salt, black pepper, paprika, and dried parsley evenly across the top. These seasonings enhance the natural flavor of the fish, adding depth and a pop of color. Make sure to coat each fillet thoroughly to ensure every bite is flavorful.
Step 6: Bake the Haddock
Carefully place the baking dish in the preheated oven and bake your Butter-Baked Haddock for 10 to 20 minutes. Every 5 minutes, baste the fillets with the pan butter to keep them moist and flavorful. The haddock is ready when it reaches an internal temperature of 145°F and flakes easily with a fork.
Step 7: Serve and Enjoy
Once cooked, remove the dish from the oven and immediately serve the Butter-Baked Haddock, drizzling the pan butter over each fillet for added richness. This simple yet delicious dish pairs beautifully with steamed vegetables or a fresh salad, making it a perfect weeknight meal.
