Pan-Seared Chilean Sea Bass with Garlic Ghee
There’s a point in late autumn when the heavy braises and roasted roots start to feel like too much — you want something that still feels like a proper dinner, but lighter, cleaner, with a little elegance on a Tuesday. The fish counter starts looking more appealing. Chilean sea bass keeps catching your eye. But it has a reputation for being a restaurant-only fish, the kind that costs $40 a plate and feels risky to attempt at home.
This recipe breaks that myth completely. You get a thick fillet with a properly golden crust, flesh that pulls apart in glossy white flakes, and a garlic ghee pan sauce that comes together in the same skillet — all in under 30 minutes, with five core ingredients. No special equipment, no culinary school required.
Pro Tip
The most common mistake with sea bass — and with most thick white fish — is pressing the fillet down into the pan right after placing it. The flesh contracts from the heat and curls up, breaking the skin contact and killing any chance of an even sear. Instead, let the fillet sit untouched for the first 90 seconds. The muscle fibers relax back down on their own, and the skin makes full contact with the pan again. From that point, don’t touch it until the crust releases naturally — usually around the 4-minute mark.
Chilean sea bass (also sold as Patagonian toothfish) is available at most fishmongers and well-stocked supermarket fish counters. Ask for skin-on fillets around 6 oz (170 g) each — the skin crisps up and helps the fillet hold together during the flip. If unavailable, thick-cut cod or halibut work well here. Ghee is sold in most grocery stores near the oils or in the international aisle; clarified butter is a direct swap.

minutesIngredients
2 Chilean sea bass fillets, skin-on, about 6 oz / 170 g each
1/2 tsp fine sea salt
1/4 tsp freshly ground black pepper
3 tbsp ghee (or clarified butter), divided
3 garlic cloves, thinly sliced
1/2 lemon, cut into thin rounds
1 tbsp fresh flat-leaf parsley, roughly chopped
Directions
- Pat dry. Press paper towels firmly against both sides of each fillet until the surface feels almost chalky — any moisture left on the fish will steam instead of sear. This single step is the difference between a golden crust and a grey, steamed fillet.
- Season. Sprinkle salt and pepper evenly over the flesh side only — seasoning the skin side at this stage draws out moisture and softens it before it hits the pan. Season from about 8 inches (20 cm) above the fish for even coverage.
- Heat the pan. Place a heavy skillet — cast iron or stainless steel — over medium-high heat for 2 full minutes before adding anything. The pan is ready when a drop of water evaporates in under a second with a sharp hiss. A non-stick pan won’t get hot enough to build a real crust on this fish.
- Add 1½ tbsp ghee and place fillets skin-side down. Let them sit untouched for 90 seconds, then press gently with a spatula if the edges are still curling. Sear for 4 to 5 minutes total until the skin is deep amber and releases cleanly from the pan. You’ll hear a steady, aggressive sizzle — if it quiets down, your pan has lost heat; turn it up slightly.
- Flip once. Sear the flesh side for 3 minutes. The fish is approaching done when the opaque white colour has crept about two-thirds of the way up the sides of the fillet. Use a fish spatula — its thin edge slides under the crust without tearing it.
- Build the sauce. Flip back to skin-side down, reduce heat to medium, and add the remaining 1½ tbsp ghee and the sliced garlic. Once the garlic turns pale gold and smells nutty — about 60 seconds — spoon the foaming ghee continuously over the fillets. Basting with a spoon rather than tilting the pan gives you more control over where the heat goes.
- Add lemon and finish. Lay the lemon rounds in the pan and cook for a further 2 minutes. The internal temperature should reach 145°F (63°C) — the flesh will flake easily when pressed with a fork and look opaque and glossy white throughout. Pull the fish off the heat at 143°F (62°C); carryover cooking will take it the rest of the way.
- Plate immediately. Spoon all the garlic ghee from the pan over each fillet and scatter with parsley. Don’t let the fish rest in the pan — it will keep cooking and dry out.
Variations
For a bolder, herb-forward version, swap the parsley for fresh tarragon and add a teaspoon of capers to the ghee sauce just before basting — the brine cuts through the richness of the fish beautifully. If you’re cooking for someone who avoids dairy entirely, refined coconut oil holds up to the same high heat and gives the crust an almost identical colour and crunch.
Serving Suggestions
A simple celery root and apple mash soaks up the garlic ghee sauce without competing with the fish. Steamed broccolini with a squeeze of the pan lemon keeps things light and lets the sea bass stay the focus. For a more substantial plate, a warm farro salad with shaved fennel and lemon zest works well with the buttery richness of the fish.
FAQ
Can I use frozen sea bass fillets?
Yes — I’ve tested this recipe with frozen fillets several times and the results hold up well. The key is a full overnight thaw in the fridge, followed by an extended pat-dry session; frozen fish releases significantly more water than fresh, so you may need to go through two or three rounds of paper towels before the surface feels truly dry.
My fillet keeps sticking to the pan — what am I doing wrong?
Almost always, it’s a pan that wasn’t hot enough before the fish went in, or the fish was moved too early. A properly seared fillet releases on its own when the crust has formed — if you have to force the spatula under it, give it another 60 seconds and try again. In my kitchen, patience at this stage has saved more fillets than any technique.
Can I make this with a different white fish?
Thick-cut halibut and black cod (sablefish) both work extremely well with this exact method and timing. Thinner fillets like tilapia or sole will overcook quickly — you’d need to cut the searing time roughly in half. It makes you wonder how the same garlic ghee sauce would change with a fish that has a smokier, more pronounced flavour — like wild-caught black cod.
