Pan-Seared Swai Fish Recipe
Swai is a mild, soft-textured freshwater fish that cooks fast and can turn mushy if handled the wrong way, so a hot pan, a dry-patted fillet, and a light dredge in flour give it a crisp exterior that holds together while the inside stays flaky. A quick pan sauce made from the same skillet picks up the browned bits for real flavor without extra dishes.

Instructions
- 1Pat the swai fillets completely dry with paper towels on both sides, this is what lets them brown instead of steam.
- 2Season both sides with salt and pepper, then dredge each fillet lightly in the flour, shaking off any excess.
- 3Heat the olive oil and 2 tablespoons of the butter in a large skillet over medium-high heat until the butter stops foaming.
- 4Lay the fillets in the skillet without crowding them and cook undisturbed for 3-4 minutes, until the underside is golden brown.
- 5Flip carefully with a thin fish spatula and cook another 2-3 minutes, until the fish flakes easily with a fork and reaches 145°F (63°C) at the thickest part. Transfer to a plate.
- 6Lower the heat to medium, add the garlic to the same skillet, and cook for 30 seconds until fragrant.
- 7Pour in the broth and lemon juice, scraping up the browned bits from the bottom of the pan with a wooden spoon.
- 8Simmer for 1-2 minutes until slightly reduced, then swirl in the remaining 2 tablespoons of butter until the sauce turns glossy.
- 9Stir in the parsley, spoon the sauce over the fillets, and serve immediately.
Tips & variations
- Buy swai fillets that are firm and moist-looking with no strong fishy smell; a sour or ammonia-like odor means it's past its prime.
- Swap the lemon butter sauce for a Cajun spice rub before dredging in flour for a spicier version.
- If the fillets are very thin, reduce the cook time per side by about a minute to avoid overcooking; swai dries out quickly past 145°F.
- A nonstick or well-seasoned cast iron skillet makes flipping the delicate fillets much easier than a stainless steel pan.
Storage & reheating
Store leftover swai in an airtight container in the refrigerator for up to 2 days. Reheat gently in a covered skillet over low heat with a splash of broth or water to keep it from drying out; microwaving tends to make the texture rubbery. Swai does not freeze well once cooked, since the flesh turns watery on thawing.
Tips from the Tulo kitchen
- Swai fillets vary a lot in thickness even within the same package, so check the thickest one with a fork or thermometer rather than timing all fillets the same.
- A splash of white wine in place of some of the broth adds extra depth to the pan sauce if it's on hand.
FAQ
What does swai fish taste like?
Swai has a very mild, slightly sweet flavor and a soft, delicate texture similar to tilapia or catfish, which is why it takes well to bold sauces and seasonings.
Is swai the same as catfish or tilapia?
No. Swai is a type of Southeast Asian catfish from the Pangasius family, farmed mostly in Vietnam, and while its texture is similar to American catfish and tilapia, it's a distinct species usually sold as thin, boneless fillets.
How do I know when swai is fully cooked?
The fillet should flake easily with a fork and turn opaque white throughout, with an internal temperature of 145°F (63°C) at the thickest part.
Can this recipe be made in the oven instead of a skillet?
Yes. Bake seasoned, floured fillets on a greased sheet pan at 400°F (200°C) for 10-12 minutes, then make the pan sauce separately in a small saucepan since there won't be browned bits in the oven.
