Barramundi Recipe

Introduction

Did you know a 6-ounce barramundi fillet has about 35 grams of protein and almost no carbs? Many people think fish is hard to cook or boring to eat. This barramundi recipe proves them wrong. In about 25 minutes, you get crispy skin, flaky white meat, and a garlic lemon butter sauce.

Barramundi, also called Asian sea bass, has a mild, buttery taste. It is a great choice if you don’t like “fishy” fish. If you want a simple barramundi fish recipe for a keto or low-carb diet, you are in the right place. I make this barramundi recipe at least twice a month, and it never fails.

Ingredients for This Barramundi Recipe

• 4 barramundi fillets (6 oz each), skin on
• 1 tablespoon avocado oil
• 3 tablespoons butter
• 4 garlic cloves, minced
• 1 lemon (juice and zest)
• 1 teaspoon sea salt
• ½ teaspoon black pepper
• ½ teaspoon paprika
• 2 tablespoons fresh parsley, chopped

Easy substitutions:

• No barramundi fillet? Use sea bass, cod, or halibut.
• Dairy-free? Swap butter for ghee or olive oil.
• No fresh lemon? Use 2 tablespoons of bottled lemon juice.

The paprika gives the skin a warm, smoky color. The garlic and butter make the kitchen smell amazing.

Timing

This barramundi recipe is faster than most oven-baked fish dinners, which often take 30 to 40 minutes. It is perfect for busy weeknights.

Step-by-Step Instructions

Step 1: Dry the Fish

Take the fillets out of the fridge 15 minutes before cooking. Pat them very dry with paper towels. Dry skin is the secret to a crispy sear.

Step 2: Season Both Sides

Sprinkle salt, pepper, and paprika on both sides of each barramundi fillet. Press the spices in gently with your fingers.

Step 3: Heat the Pan

Add the avocado oil to a large skillet over medium-high heat. Wait until the oil shimmers. A cast-iron pan works best.

Step 4: Sear Skin-Side Down

Place the fillets in the pan, skin side down. Press each one with a spatula for 10 seconds so the skin stays flat. Cook for 5 to 6 minutes without moving it. You will see the flesh turn white from the bottom up.

Step 5: Flip and Baste

Flip the fish and add the butter and garlic to the pan. Tilt the pan and spoon the melted butter over the fish for 2 to 3 minutes. The fish is done when it flakes easily with a fork. The USDA recommends an internal temperature of 145°F for fish, so use a thermometer if you want to be sure.

Step 6: Finish with Lemon

Turn off the heat. Squeeze in the lemon juice, add the zest, and sprinkle on the parsley. Spoon the sauce over the fish and serve right away. That is the whole barramundi recipe.

Common Mistakes to Avoid

Most problems with a barramundi recipe come from a few small errors:

1. Wet fish. Moisture steams the skin instead of crisping it. Always pat it dry.
2. A cold pan. The oil must be hot before the fish goes in.
3. Moving the fish too soon. Let it release naturally from the pan.
4. Overcooking. Barramundi goes from perfect to dry in just 1 to 2 minutes. Use a thermometer if you can.
5. Crowding the pan. Cook in two batches if needed.

Storing Tips for the Recipe

Leftovers from this barramundi recipe keep well:

• Fridge: Store in an airtight container for up to 2 days.
• Reheating: Warm gently in a skillet over low heat or in a 275°F oven for 8 to 10 minutes. Avoid the microwave, which can dry out the fish.
• Freezer: Freeze the uncooked, seasoned fillets for up to 2 months.
• Meal prep: Mix the garlic, lemon zest, and spices ahead of time and keep them in the fridge for 1 day.
