Butter Fish Recipe

I always love finding a quick dinner idea that feels genuinely special, especially when it involves a flavorful fish fillet.

This pan-seared butter fish recipe delivers exactly that, transforming flaky, rich fillets into a restaurant-quality meal with minimal fuss.

The secret is a velvety roasted red pepper cream sauce that comes together while the fish sears. The combination of perfectly seared butter fish and rich sauce makes this a truly easy dinner idea for a weeknight when you want something impressive without spending hours in the kitchen.

This butter fish recipe focuses on maximizing flavor without complicated techniques, making it a new favorite for family dinners.

Ingredients

• 4 butter fish fillets (150-180g / 5-6 oz each), skin on or off: Pat the fish completely dry with paper towels before seasoning; this ensures a crisp sear. Butter fish (also known as sablefish or black cod) is ideal for its high oil content, which keeps it tender and moist.
• 2 large red bell peppers (approx. 400g / 14 oz), halved and deseeded: The peppers form the sweet and vibrant base of the cream sauce. Choose firm, bright red peppers without blemishes for the best flavor.
• 1 small yellow onion (approx. 100g / 3.5 oz), finely chopped: This creates the savory aromatic foundation for the sauce. Finely chop to ensure it blends smoothly later without leaving fibrous pieces.
• 2 cloves garlic (approx. 10g / 0.35 oz), minced: Fresh garlic adds essential depth and aroma to the sautéed base. Avoid pre-minced garlic for the freshest flavor in the sauce.
• 120 mL (1/2 cup) vegetable broth: Used to thin the sauce base before adding cream and to aid in blending. A low-sodium broth allows you to control the final seasoning better.
• 120 mL (1/2 cup) heavy cream: Essential for achieving the rich, creamy, and velvety texture of the sauce. For a lighter version, try half-and-half, but be aware it won’t be as thick.
• 5 mL (1 teaspoon) smoked paprika: This gives the sauce its signature smoky flavor and enhances the red color. Use smoked paprika, not sweet paprika, for the intended flavor profile.
• 30 mL (2 tablespoons) olive oil, divided: Used for both sautéing the vegetables for the sauce and searing the fish fillets. A good quality extra virgin olive oil works for the sauce; use a neutral oil for searing if a higher smoke point is preferred.
• 5 mL (1 teaspoon) sea salt, divided: Used for seasoning both the fish and the sauce to balance flavors. Use half for the sauce and half for seasoning the fish.
• 2.5 mL (1/2 teaspoon) black pepper, divided: Used for seasoning both the fish and the sauce. Freshly cracked pepper provides a better aroma and flavor than pre-ground pepper.
• 15 mL (1 tablespoon) fresh parsley, finely chopped, for garnish: Adds a pop of contrasting color and freshness to the final dish. Sprinkle generously just before serving for visual appeal and a fresh note.

Instructions

Here’s how to create this simple yet elegant butter fish recipe from scratch, maximizing flavor while minimizing active time in the kitchen.

1. Roast the Red Peppers

   Preheat the oven to 200°C (400°F). Place the halved red bell peppers, cut-side down, on a baking sheet.

   Roast for 20-25 minutes, or until their skins are softened and lightly charred. Transfer the peppers to a heatproof bowl, cover tightly with plastic wrap, and let them steam for 10 minutes; this helps loosen the skins for easy peeling.

   Once cooled enough to handle, peel off and discard the skins, leaving just the soft, roasted flesh for the sauce base.

2. Sauté Aromatics for the Sauce

   While the peppers roast, heat 15 mL (1 tablespoon) olive oil in a medium saucepan over medium heat.

   Add the finely chopped onion and sauté for 5-7 minutes until softened and translucent, stirring frequently. Add the minced garlic and cook for another 1 minute until fragrant; be careful not to brown the garlic, as it can become bitter.

3. Blend the Cream Sauce Base

   Transfer the peeled roasted red peppers and the sautéed onion/garlic mixture into a blender.

   Add the vegetable broth and smoked paprika to the blender. Blend until the mixture is completely smooth and uniform in color, ensuring no large chunks remain. I often find blending while the fish rests helps streamline the cooking process, letting me get everything ready at once.

4. Finish and Simmer the Sauce

   Pour the blended sauce base back into the medium saucepan over medium-low heat.

   Stir in the heavy cream, 2.5 mL (1/2 teaspoon) salt, and 1.25 mL (1/4 teaspoon) pepper. Bring to a gentle simmer for 5-7 minutes, stirring occasionally, until the sauce slightly thickens to a pourable consistency; taste and adjust seasoning as needed. Keep warm.

5. Prepare and Season the Fish Fillets

   Pat the butter fish fillets thoroughly dry with paper towels; removing excess moisture is critical for achieving crispy skin.

   Season both sides of the fillets with the remaining 2.5 mL (1/2 teaspoon) salt and 1.25 mL (1/4 teaspoon) pepper. Ensure your large non-stick skillet is clean and dry before adding oil.

6. Pan-Sear the Butter Fish

   Heat the remaining 15 mL (1 tablespoon) olive oil in the large non-stick skillet over medium-high heat until shimmering hot.

   Carefully place the fish fillets, skin-side down (if applicable), into the hot skillet. Cook for 3-5 minutes, allowing a golden-brown, crispy skin to form, then flip and cook for another 2-4 minutes until opaque and flaky throughout.

7. Plate and Garnish

   To plate, ladle a generous pool of the warm Roasted Red Pepper & Smoked Paprika Cream Sauce onto the center of a clean plate.

   Carefully place one seared butter fish fillet on top of the sauce. Garnish generously with freshly chopped parsley, adding a vibrant green contrast to the rich red sauce and white fish. This plating technique creates a beautiful presentation for a simple butter fish recipe.

What to Serve with Pan-Seared Butter Fish and Cream Sauce

Garlic Herb Roasted Potatoes

These potatoes are easy to prepare and pair perfectly with the rich sauce. Roast them alongside the peppers to save time and cleanup. I like to toss mine with a little rosemary and thyme for extra flavor. They provide a sturdy base for a hearty family dinner.

Creamy Parmesan Risotto

A rich and comforting side dish that complements the sauce beautifully. Stir in some fresh asparagus or peas at the end for added color and texture. The risotto soaks up extra sauce for a luxurious bite, making this a truly memorable meal.

Simple Steamed Green Beans or Asparagus

A light, crisp side dish to balance the richness of the cream sauce. Squeeze fresh lemon juice over the vegetables to enhance their natural flavor. This option keeps the meal feeling fresh and healthy, cutting through the richness of the butter fish recipe sauce.

Tips for Perfect Pan-Seared Butter Fish Every Time

Patting the Fish Dry

This is the most important step for achieving crispy skin on a pan-seared fillet. Remove as much moisture as possible from the surface of the fish before seasoning. This creates a barrier against steam and promotes a quick, hard sear.

Don’t Overcrowd the Pan

Cook the fish in batches if necessary to prevent the temperature from dropping too low. Overcrowding leads to steaming instead of searing, resulting in soggy skin. A good rule for this butter fish recipe is to ensure there is space between the fillets.

The Doneness Test

The fish is done when it easily flakes apart with a fork at its thickest point. A good rule of thumb is 10 minutes of total cooking time per inch of thickness. For a perfectly cooked butter fish fillet, it should be opaque throughout but still incredibly tender.

FAQs

What is butter fish (sablefish)?

Butter fish (also known as sablefish or black cod) is highly valued for its high fat content and delicate, buttery flavor. Its texture becomes flaky and soft when cooked, and its high oil content makes it difficult to overcook. This makes it a great choice for this healthy eating recipe.

How do I keep my fish from sticking to the pan when searing?

Ensure your pan and oil are fully heated before adding the fish. Pat the fish completely dry and place it carefully in the pan; do not move it for several minutes until a crust forms. Using a non-stick pan or a well-seasoned cast-iron skillet helps a lot.

Can I use other types of fish with this sauce?

Yes, this sauce pairs well with any white, flaky fish like cod, halibut, or even salmon. A firm white fish like cod or halibut will hold up well to the rich sauce. This butter fish recipe technique works for most firm fillets, though I prefer sablefish for its buttery texture.

Can I make the roasted red pepper sauce ahead of time?

Yes, the sauce can be made completely ahead and stored in an airtight container for up to 3 days in the refrigerator. Reheat gently on the stovetop over low heat, stirring frequently; add a splash of broth or cream if it seems too thick. This makes meal prep a breeze and simplifies weeknight dinners.

What can I use instead of heavy cream for the sauce?

For a dairy-free alternative, you can try full-fat coconut milk for a similar richness (though it adds a slight coconut flavor). For a lighter sauce, use half-and-half, but be aware it won’t be as thick or creamy. I’ve found that a small amount of blended cashews also works well for a high-protein option.
