Pan Seared Chilean Sea Bass

Craving a fish dinner with crisp edges, a buttery center, and plenty of lemon sauce? Pan Seared Chilean Sea Bass gives you all three in just 15 minutes. Alphafoodie

This simple dinner uses thick Chilean sea bass fillets seared in butter and olive oil, then finished with a warm lemon butter sauce. The fish stays tender and flaky beneath that golden surface.

With 5 minutes of prep and 10 minutes of cooking, it is especially handy when you want a fast seafood dinner without turning on the oven. Alphafoodie If quick seafood is your thing, Creamy Shrimp Fettuccine Alfredo is another comforting option for your dinner list.

I leave the fillets completely alone during those first few minutes in the skillet. Once the surface has properly seared, the fish releases much more easily instead of tearing when you flip it.

Spoon plenty of lemon butter over each portion and serve it with potatoes, rice, vegetables, or a crisp salad. A slice of Crusty No Knead Bread is also very good for catching the sauce left on the plate.

It works beautifully for a quick weeknight dinner, but the thick flaky fillets also make it feel special enough for date night or a relaxed dinner with friends.

Ingredients You’ll Need

You only need a short ingredient list for this rich, lemony fish dinner. Alphafoodie

• Chilean sea bass: 20 to 24 oz, or 4 fillets weighing 5 to 6 oz each, with skin on preferred.
• Butter or ghee: 1.5 tablespoons for searing the fish.
• Olive oil or avocado oil: 1.5 tablespoons helps the fillets brown in the skillet.
• Salt: ½ teaspoon, or to taste.
• Black pepper: ¼ teaspoon, or to taste.

Lemon Sauce

• Unsalted butter: 2 oz, or ¼ cup, creates the rich sauce.
• Lemon juice: 2 tablespoons, from about ½ large lemon.
• Salt: ½ teaspoon balances the buttery sauce.
• Black pepper: ¼ teaspoon adds a little savory bite.

Step by Step Instructions

1. Dry and season: Pat the sea bass thoroughly dry with paper towels, then season both sides with salt and black pepper. Removing surface moisture helps the fish brown instead of steam. Alphafoodie
2. Heat the skillet: Add 1.5 tablespoons butter and 1.5 tablespoons oil to a large skillet over medium high heat. Let the pan get properly hot before adding the fish.
3. Sear the fish: Place the fillets in the skillet with the skin side down and cook for 3 to 4 minutes per side. If a fillet sticks when you try to turn it, give it another 10 to 15 seconds before trying again. Alphafoodie
4. Check for doneness: Cook until the flesh flakes easily with a fork and the center reaches 140 to 145°F, or 60 to 63°C. Very thick fillets may need closer to 5 minutes per side. Alphafoodie
5. Make the sauce: Melt the ¼ cup unsalted butter in a small saucepan over medium low heat until lightly browned. Stir in the lemon juice, salt, and black pepper. Alphafoodie
6. Finish and serve: Transfer the fish to plates and spoon the warm lemon butter sauce generously over the top. Serve right away while the exterior is still golden.

Recipe Tips

• Dry it well: Moisture left on the fillets works against good browning, so take a moment to pat every surface dry.
• Preheat properly: Add the fish only once the butter and oil are hot enough to sear the surface immediately.
• Wait to flip: Do not force fish that is sticking to the skillet. A properly seared fillet should release much more easily. Alphafoodie
• Check the center: A thermometer is especially useful with thick fillets since their cooking time can vary considerably.

Variations and Customization Ideas

• Fish swap: Black cod is a particularly close substitute, while regular sea bass, haddock, or tilapia can also be used. Alphafoodie
• Garlic sauce: Add minced garlic to the lemon butter for another savory layer.
• Fresh herbs: Finish with chopped parsley for a fresh, colorful touch.
• Dairy swap: Use ghee instead of butter if that better suits your needs.
• Oil option: Avocado oil can take the place of olive oil for searing. Alphafoodie

Serving Suggestions

• Creamy potatoes: Mashed potatoes are excellent underneath the fish because they catch all that lemon butter.
• Simple grains: Rice or quinoa gives you a mild base that lets the sea bass stay front and center.
• Fresh greens: A crisp salad adds welcome freshness alongside such a rich fish.
• Green vegetables: Asparagus, green beans, spinach, or roasted Brussels sprouts all pair naturally with lemon and butter. Alphafoodie
• Easy alternative: Save One Pot Greek Chicken Orzo for another bright, lemony dinner when chicken sounds better than seafood.

How to Store and Reheat

Let leftover sea bass cool, then refrigerate it in an airtight container for up to 3 days. Do not leave cooked fish sitting at room temperature for more than 2 hours.

For longer storage, freeze the cooked fish without the sauce for up to 2 months and thaw it overnight in the refrigerator. Alphafoodie

Reheat gently on the stove over medium low heat with a small splash of water and a lid on the pan. Avoid high heat since it can dry out the delicate fish, and make sure leftovers are heated thoroughly before serving.

Recipe FAQ’s

How do I know when Chilean sea bass is cooked?

The flesh should look opaque and separate easily into moist flakes with a fork. The source recipe recommends an internal temperature of 140 to 145°F, or 60 to 63°C. Alphafoodie

Why is my sea bass sticking to the pan?

It may simply need more time to develop its seared surface. If it resists when you try to flip it, wait another 10 to 15 seconds and check again rather than forcing it loose. Alphafoodie

Can I cook frozen Chilean sea bass?

Yes, but thaw the fillets completely before cooking them. Pat them very dry before seasoning so excess moisture does not interfere with browning. Alphafoodie

Pan Seared Chilean Sea Bass keeps dinner wonderfully simple: tender flaky fish, a golden sear, and bright lemon butter, all ready in about 15 minutes.
