The Origins and Keto Benefits of Grilled Chilean Seabass with Herb Butter

The Keto Grilled Chilean Seabass with Herb Butter is a dish that has its roots in gourmet kitchens but has been adapted for the keto lifestyle. The high-fat content of the seabass aligns perfectly with the macronutrient requirements of a ketogenic diet, ensuring you remain in a state of ketosis. The fish itself is a powerhouse of omega-3 fatty acids, which are essential for heart health and cognitive function.

**Herb butter**, a key component of this dish, is not only flavorful but also a great source of healthy fats from butter, which is a staple in the keto diet. Fresh herbs like parsley, chives, and thyme add a burst of flavor without adding carbs, making them ideal for enhancing dishes without compromising your carb limit. The combination of these ingredients results in a meal that is as nutritious as it is delicious.

When selecting ingredients for a keto-friendly meal, it’s essential to consider both the carb content and the nutritional value. This recipe does just that, focusing on high-quality, low-carb ingredients that provide a balance of protein and fats. The seabass, with its high protein content, helps with satiety, while the herb butter, rich in fats, fuels the body’s need for energy on a keto diet.

Herb Butter Preparation

Mastering the Method: Tips for Perfectly Grilled Seabass

Grilling Chilean Seabass to perfection requires attention to detail and a few chef’s secrets. Preheating the grill to the right temperature is crucial for achieving that desirable sear without overcooking the delicate fish. A medium-high heat ensures the seabass cooks through while retaining its moisture.

When it comes to seasoning, simplicity is key. A generous brushing of olive oil followed by salt and freshly ground black pepper enhances the natural flavors of the fish. The real magic happens when you allow the seabass to cook undisturbed, creating a beautifully crisp exterior.

The herb butter should be prepared with softened butter to ensure it melds seamlessly with the finely chopped herbs and garlic. This aromatic mixture should be at room temperature when dolloped onto the freshly grilled seabass, allowing it to melt and infuse the fish with its herby goodness. Remember, the butter not only adds flavor but also contributes to the dish’s fat content, making it a perfect keto condiment.

Variations to Spice Up Your Seabass

Lemon Caper Topping

For a tangy twist, try a lemon caper topping. Combine capers, lemon zest, and a splash of lemon juice with the herb butter for a zesty flavor that cuts through the richness of the fish.

Spicy Herb Butter

Add a kick to your dish with some heat. Incorporate a pinch of cayenne pepper or diced jalapeño into the herb butter for a spicy version that tantalizes the taste buds.

Mediterranean Salsa

Create a fresh Mediterranean salsa with diced tomatoes, olives, cucumbers, and a hint of red onion. Drizzle with olive oil and lemon juice for a refreshing accompaniment to the grilled seabass.

Substitutions for a Tailored Keto Experience

While Chilean Seabass is a fantastic choice for this recipe, you can substitute it with other fatty fish like salmon or halibut. These options are equally rich in omega-3s and maintain the keto-friendly fat profile.

If you’re dairy-sensitive, replace the traditional butter with ghee or coconut oil. These alternatives still provide the necessary fats for keto and offer a slightly different, but equally delicious, flavor profile.

For those who don’t consume garlic, try using garlic-infused olive oil in the herb butter for a subtle garlic flavor without the actual cloves.

For the Seabass

  • 4 Chilean seabass fillets 6 ounces each (170 grams each)
  • 2 tbsp olive oil 30 ml
  • Salt and freshly ground black pepper to taste

  • 1 tbsp fresh chives finely chopped (3.8 grams)
  • 1 tsp fresh thyme leaves 0.8 grams
  • 1 clove garlic minced

  • Preheat your grill to a medium-high heat, approximately 400°F (204°C).
  • Pat the seabass fillets dry with paper towels and brush both sides with olive oil. Season generously with salt and black pepper.
  • In a small bowl, combine the softened butter, chopped parsley, chives, thyme, and minced garlic. Season with salt and pepper to taste, and mix until well combined. Set aside at room temperature.
  • Place the seabass fillets on the grill, skin side down, and cook for about 5 minutes without moving them. This will help to create a nice sear and prevent sticking.
  • Carefully flip the fillets and continue to cook for an additional 4-5 minutes, or until the fish flakes easily with a fork.
  • Remove the seabass from the grill and immediately top each fillet with a generous dollop of the prepared herb butter.
  • Garnish with lemon slices and chopped parsley before serving.


Ensure your grill is clean and oiled before cooking to prevent the fish from sticking.
The fish is done when it reaches an internal temperature of 145°F (63°C).
If you do not have a grill, you can also cook the seabass in a grill pan over medium-high heat on the stove.
The herb butter can be made in advance and stored in the refrigerator. Bring to room temperature before using to ensure it melts beautifully over the warm fish.
For an even lower carb count, you can reduce the amount of herb butter used per serving.
