Two thick pieces of raw white fish fillet are placed side by side on a round white plate in the center. To the right of the plate, there are three small white square bowls arranged in a loose triangle, each holding a different seasoning: the top bowl contains a coarse brown and green spice mix, the bottom bowl has a light green and white mixture with fine texture, and the right bowl holds a small smooth ball of pale yellow butter.

Getting ready to make this Grilled Chilean Sea Bass with Mango Salsa Recipe means gathering a handful of essential ingredients that each bring their own magic to the dish. From the rich, flaky fish to the sweet and tangy salsa, every component works together to create a balanced, flavorful meal.

  • Chilean sea bass, 1 pound: Choose center-cut filets for even cooking and a luxurious texture.
  • Butter, 1 tablespoon (melted): Adds richness and helps the seasonings adhere to the fish perfectly.
  • Old Bay seasoning, 1 teaspoon: A classic blend that brings a subtle spice and warmth.
  • Garlic salt, 1 teaspoon: Gives a savory punch and complements the natural flavors of the fish.
  • Chopped chives: A fresh herb garnish that adds a mild onion flavor and vibrant green color.
  • Mango salsa: The star sidekick, offering a refreshing mix of sweetness and acidity that brightens the entire dish.

How to Make Grilled Chilean Sea Bass with Mango Salsa Recipe

Step 1: Preheat the Grill

Start by heating your grill to about 375 degrees Fahrenheit so that the grates are scorching hot. This heat level helps you get those perfect grill marks and a delicate crust on the Chilean sea bass while keeping the fish juicy inside.

Step 2: Prepare the Sea Bass

Brush all sides of your sea bass filets generously with melted butter. This step not only adds flavor but also helps the fish achieve a beautiful golden finish without sticking to the grill.

Step 3: Season Generously

Sprinkle Old Bay seasoning and garlic salt evenly over every side of the filets. Don’t be shy here—this seasoning blend complements the buttery fish and enhances those smoky grill flavors perfectly.

Step 4: Start Grilling

Place the filets on the hot grill grates and let them cook undisturbed for a few minutes. This is crucial for building that initial crust and making sure the fish doesn’t fall apart when you flip it.

Step 5: Add Basting Covers and Continue Cooking

Cover each filet with a basting cover to trap the heat and moisture. Cook the fish for between 3 to 5 minutes, allowing it to steam gently inside the cover for an even finish.

Step 6: Flip and Finish Grilling

Remove the basting covers, flip the filets carefully, then cover and cook again for an additional 3 to 5 minutes. Make sure the internal temperature reaches between 140 and 145 degrees F for flaky, perfectly cooked sea bass.

How to Serve Grilled Chilean Sea Bass with Mango Salsa Recipe

A thick, lightly seasoned grilled white fish piece sits centered on a bed of fluffy white rice scattered with small green chive pieces. On top of the fish is a colorful mix of small, diced red, yellow, and orange tomatoes, also sprinkled with chopped green chives. A few pieces of diced tomatoes and chives are placed around the rice on the edge of the white plate. The background shows a white marbled texture with blurred green onions and some more tomatoes in the distance. photo taken with an iphone --ar 4:5 --v 7

Garnishes

Fresh chopped chives are the ideal garnish here, lending a subtle burst of color and mild onion flavor that complements the sweetness of the mango salsa. A light sprinkle over the top just before serving adds a lovely finishing touch.

Side Dishes

For side dishes, think light and fresh. A crisp green salad or grilled seasonal vegetables pair beautifully, helping to balance the richness of the sea bass. Steamed jasmine rice or quinoa works wonderfully if you want something more hearty.

Creative Ways to Present

Try serving the sea bass directly on a banana leaf or a rustic wooden platter to bring a tropical vibe to the table. Spoon the mango salsa generously on top or on the side to keep flavors bright and fresh. A wedge of lime adds both color and a zesty twist waiting to be squeezed over each bite.

Make Ahead and Storage

Storing Leftovers

If you find yourself with leftovers of this Grilled Chilean Sea Bass with Mango Salsa Recipe, store them covered in an airtight container in the refrigerator. The fish will stay fresh for up to two days, maintaining most of its original flavor and texture.

Freezing

Freezing cooked sea bass isn’t ideal because it can alter the fish’s delicate texture, but if necessary, wrap each piece tightly in plastic wrap and then foil. Freeze for up to one month to preserve the best quality.

Reheating

To reheat, gently warm the fish in a low oven (around 275 degrees F) covered with foil to avoid drying out. Avoid microwaving if possible, as this often makes the sea bass tough and rubbery. Reheat the mango salsa separately and serve fresh.

FAQs

Can I use other types of fish for this recipe?

While Chilean sea bass is known for its tenderness and rich flavor, you can substitute with other thick, flaky white fish like halibut or cod. Keep in mind the cooking times may vary slightly.

How spicy is the Old Bay seasoning?

Old Bay offers a mild warmth with a mix of paprika, celery salt, and other herbs and spices. It adds complexity without making the dish overly spicy, making it perfect for all palates.

Can I prepare the mango salsa ahead of time?

Absolutely! Mango salsa can be made a few hours or even the day before. Letting it chill allows the flavors to meld beautifully, but be sure to store it in an airtight container in the fridge.

What if I don’t have a grill?

You can easily prepare this recipe using a grill pan on your stovetop or even broiling the sea bass in the oven. The key is high, direct heat to replicate the grilling effect.

What’s the best way to test if the sea bass is cooked?

Use a meat thermometer to check that the internal temperature reaches between 140 and 145 degrees F. The fish should flake easily with a fork but still feel moist and tender.

Final Thoughts

This Grilled Chilean Sea Bass with Mango Salsa Recipe is a true gem that brings together simple ingredients and straightforward techniques to create something truly special. Whether you’re cooking for a special occasion or just want to treat yourself to an unforgettable meal, this recipe delivers every time. Give it a try and enjoy the delightful blend of smoky, buttery fish topped with the bright sweetness of mango salsa—you won’t regret it!

Description

This Grilled Chilean Sea Bass recipe offers a deliciously tender and flavorful seafood dish, enhanced with melted butter, Old Bay seasoning, and garlic salt. Perfectly grilled to achieve a crispy crust and juicy interior, it is served with a fresh mango salsa and garnished with chopped chives, making a simple yet elegant meal ready in just 20 minutes.


Ingredients

Sea Bass

  • 1 pound center cut Chilean sea bass (453g, 16 ounces)
  • 1 Tablespoon butter (melted)
  • 1 teaspoon Old Bay seasoning
  • 1 teaspoon garlic salt

Garnish and Sauce

  • Chopped chives, for garnish
  • Mango salsa, for serving


Instructions

  1. Preheat Grill: Preheat your grill to 375°F (190°C) so that the grates get nice and hot, providing the perfect searing surface for the sea bass.
  2. Brush with Butter: Brush the sea bass filets thoroughly on all sides with the melted butter to add flavor and help them develop a crisp crust on the grill.
  3. Season Filets: Evenly season the filets on all sides with Old Bay seasoning and garlic salt, ensuring every bite has a balanced, savory taste.
  4. Initial Cooking: Place the filets on the hot grill and allow them to cook undisturbed for a couple of minutes to start forming a crust.
  5. Baste and Cook: Cover each filet with a basting cover to retain moisture and cook for 3-5 minutes, allowing the fish to cook gently and absorb the flavors.
  6. Flip and Finish Cooking: Remove the basting covers, flip the filets over carefully, cover again with the basting covers, and cook for an additional 3-5 minutes or until the internal temperature reaches 140-145°F (60-63°C), ensuring the fish is perfectly cooked and flaky.
  7. Serve: Remove the sea bass from the grill, garnish with chopped chives, and serve immediately with fresh mango salsa alongside for a sweet and spicy contrast.

Notes

  • Use a meat thermometer to check the internal temperature for perfect doneness.
  • If you don’t have a basting cover, you can use aluminum foil tented over the filets.
  • Mango salsa adds a refreshing, fruity element that complements the rich fish perfectly.
  • Adjust seasoning amounts to taste, especially if using salted butter.
  • Allow the fish to rest briefly after grilling to let juices redistribute.
