I’ve cooked countless delicate white fish fillets and this hybrid cast-iron method is HANDS DOWN the best way to guarantee a crispy skin without the stress of flipping. This sea bass recipe also uses basil oil for a brighter & lighter flavour. So good! If you want to pair this sea bass fillet recipe with a quick side, make sure to try my Roasted Tenderstem Broccoli.

For a great appetiser to serve before dinner, you should make Smoked Mackerel Pâté, Crostini Bruschetta Bites, and Garlic Prawns.

There are so many great sea bass recipes you can build from this base:

Step 1: Preheat grill to 200°C/400°F. Pat the sea bass fillets with a paper towel to remove any excess moisture, and season both sides with salt and pepper.

Step 2: To a food processor, add olive oil, fresh basil, the juice of half a lemon, garlic, and salt and pepper.

Step 3: Heat olive oil in a cast-iron pan. Place the sea bass skin-side down and leave to fry until crispy. Remove from the pan, add olive oil, and add the courgettes and the cherry tomatoes into the pan.

Step 4: Fry for 3 minutes, then rotate the courgettes and stir the tomatoes in the pan. Season generously with salt and pepper.

Step 5: Add the sea bass back into the pan, skin facing down. Brush with basil oil, then add the olives. Pop under the grill for 10-15 minutes.

Step 6: Finish with the remaining basil oil, lemon wedges, black pepper and optional chilli flakes. Dig in!

The basil oil in this sea bass recipe is honestly one of the best sea bass sauce options I’ve come across. It’s worth spooning over grains like Creamy Rice with Garlic & Parmesan, or crusty bread to soak up every last bit. Some great side options for these would be Air Fryer Green Beans, Skillet Roasted Corn, and these Honey-Roasted Carrots & Parsnips. They’re also great served as a starter-sized portion if you’re cooking dishes like Beef Minestrone Soup and Chicken Bolognese for a crowd and want something that looks impressive without much effort.
Refrigerator: Put the completely cooled fish, courgettes, and tomatoes in an airtight container and keep in the fridge for up to 3 days.
Freezer: Freezing this sea bass recipe isn’t recommended.
Reheat: Warm gently in a skillet over medium-low heat with a small splash of water or stock to stop the fish from drying out.
The flesh is done when the thickest part turns opaque and flakes easily with a fork. If you want to be precise, an instant-read thermometer should read 140°F to 145°F (60°C to 63°C).
Yep, skinless works fine, though you’ll miss out on the crispy skin which is honestly what makes this the best sea bass recipe. If you’re going skinless, just sear the bottom for 2 minutes before transferring the pan to the grill.
Black cod, halibut, or thick cuts of regular cod are all great alternatives. They share a similar firm & flaky texture, and hold up really well in a cast-iron pan.
When learning how to cook seabass at home, please pat the fish completely dry and make sure the pan and oil are properly hot before the fish touches them. Moisture & a cold pan are the two things that will ruin your sear every time, and that’s true of any sea bass fillets recipes you try.
