Swai Fish is cooked in a lemon butter garlic sauce with fresh ginger and capers. It makes an excellent quick dinner entree as it only takes under 30 minutes from start to finish. It is highly versatile and quite affordable as well!

This is a budget-friendly recipe that is perfect for a light and quick dinner. Because the fish flavor is neutral, you can dress it up in your favorite sauce or marinade. To keep it healthy and filling, serve it with Air Fryer Roasted Asparagus or Sauteed Cabbage. This meal is such a time-saver, and it’s great since it pairs so well with many appetizers and dishes. Make sure to check our other fish recipes, there is plenty to choose something for every taste and budget.

Since the fish flavor is very mild and neutral, it reminds me of tilapia, you can play with the other ingredients to add more flavor. I enjoy my filets cook in a buttery sauce, that has been flavored with fresh lemon, fresh garlic, and ginger. Using fresh ingredients is key, as it enhances the flavors of the dish.

What we like about this type of fish is that it is not fishy at all. It is lean and holds up pretty well as you cook it. In addition, it absorbs the flavors in which it is cooked easily, so you can make numerous recipes with it. If you are looking for a quick, delicious, and budget-friendly dinner, then this swai fish recipe is the way to go!

The baked swai fillet is tender, buttery, filled with citrus flavor, and made in one pan for your convenience.

What is swai fish?

Sometimes called Basa or Pangasius, it has white flesh and strives in freshwater just like tilapia but with a milder flavor. The majority of the country’s supply comes from the Mekong Delta in Vietnam. It is a naturally neutral flavor which makes it an ideal dinner dish.

Also, it is quite inexpensive, considering that it hails all the way from Asia. With that said, you will mostly find it as frozen fillets and individually packed. Also, you can use it readily with almost zero preparation.

Ingredients needed:

  • Swai fish fillets
  • Salt and pepper
  • Vegetable oil

For the Garlic Butter Sauce:

  • Unsalted butter
  • Fresh garlic
  • Fresh ginger
  • Capers
  • Fresh lemon juice
  • Red pepper flakes
  • Fresh chopped parsley

How to cook swai fish?

There are many ways on how to cook, and some of our favorite ways are to pan-fry and bake it. The important thing is to be able to reach 145 degrees of internal temperature when cooking this swai dish. This is to kill any bacteria that it may have. Also, before cooking it, make sure to rinse the swai well under cold water, and after that dry it with paper towels.

  1. Prepare the fish fillets: First, rinse them under cold water, and after that place them on a plate lined with paper towels. Also, use some paper towels to pat them dry.
  2. Cook: Next, place a large skillet over medium-high heat and add the oil. Once the oil is hot start frying swai fish fillets for a few minutes on each side until lightly browned. Remove the pan-fried fillets and place them on a plate.
  3. Make the sauce: After that add to the pan the butter and melt it. Afterward add the garlic and ginger to the melted butter, cook for a few minutes. Next, add the capers, lemon juice, parsley, and red pepper flakes. Stir and bring the sauce to a light boil, remove from heat.
  4. Add back the fillets: Finally, add back the fillets into the pan and spoon the sauce on top of them.
  5. Serve: Now serve the dish immediately, with freshly chopped parsley, lemon wedges, and a side dish of your choice.

Recipe Variations:

  • Baked Sway fillets: Alternately, you can use the same set of ingredients but instead of frying it, you can bake it. To bake Swai fish, simply put the fillets in a casserole dish and bake them in the oven preheated at 400 degrees. Do not forget to spray some cooking spray first. Prepare the sauce the same way and pour over the fillets. Bake further until the flesh comes off easily. This should be done in about 20 minutes.
  • Crispy: Follow this Crispy Baked Tilapia recipe to make a crisp shell on it.
  • Change the sauce: Since this is such an easy swai recipe after you pan fry the Swai, we recommend trying to cook it into one of these Asian Sauces: Orange Sauce, General Tso Sauce, Sweet, and Sour Sauce, Szechuan Style Sauce.
  • Spicier: Also, make this dish spicier by adding more red pepper flakes and some hot sauce.
  • Citrus: Use lime or oranges instead of lemon.
  • Marinate: Actually, marinating is great because it gives some time for the flavors to properly absorb and reflect in the final dish. So if you have some extra time, feel free to marinate it, and just grill or cook it after. Let it sit in the marinade for about 30 minutes or more but not exceeding one whole day. Use a mix of olive oil, soy sauce, white wine, lemon juice, honey, and seasoning to make the marinade.
  • Grill: After marinating it, instead of baking or frying, grill the fillets and brush with the marinade occasionally. Once done, boil the remaining marinade for about a minute and serve as the sauce.

How to serve it:

How to store leftovers:

  • Store: If you have leftovers, first let them cool, and after that add them to an airtight container and store them in the fridge for up to 3 days.
  • Freeze: However, if you prefer to freeze this dish, let it cool first and wrap in plastic wrap, after that in foil and add it to a freezer-safe Ziploc bag. Freeze for up to 3 months.
  • Defrost: To thaw transfer it to the fridge and let it stand overnight. Reheat and serve.

Frequently Asked Questions:

Are swai fillets healthy?

It does not have high levels of omega-3 fat and protein, unlike many other species. But it does have high levels of niacin, vitamin B12, and selenium depending on how it was fed. Also, it is high in lean protein, making it a great option for a filling dinner.

Is it a clean fish?

While this white fish is an inexpensive and budget-friendly seafood option, many people believe that the meat is contaminated and dangerous to it. If grown in an environment contaminated with chemicals and injected with hormones, obviously the meat will absorb them and become toxic to consumers. Therefore, when choosing Swai, make sure it is from reliable farms, that utilize clean rivers and ponds.

Is it the same as Tilapia?

While when cooked both fish is white, tender, and flaky with a neutral taste, Tilapia tends to be fattier. Also, it may have some darker bits to the flesh.
Swai comes from Southeast Asia and gets shipped frozen to the States, whereas tilapia gets caught and raised all over the world. Actually, both make great options for fried fish cookouts.

Very good whole family loved it



I have never been big on eating fish. I had never used capers in anything, and didn't even know what they were but I love to cook and decided to try this recipe. I can tell you now, I am a big fish eater now & have made this 5 times in the last month. This recipe is AMAZING and you will crave this fish recipe if you try it. Thank you to whom ever came up with this recipe.



I baked my fish. It came out beautifully delicious.


Perfect! Thanks for your feedback!



The flavor of this recipe is great. It does taste really good; however, the baking time does not seem accurate. At 400° my fish was not even close to ready in 20 minutes. It took almost 45 minutes to finish completely. I would caution others to plan to bake for 35-40 min accordingly, so your fish is done on time for dinner. Maybe I'm the only one who tried to bake it, but that's how I make my fish typically!


Thanks! We usually bake at 20 minutes as fish quicks quickly and we don't want to overcook it. Generally, we never had any issues. But if you feel like more time is needed, then this is ok as well. Thanks for stopping by.



This looks so amazing and appetizing, really 5-star deserving recipe.



I’m a novice when it comes to cooking fish. Your recipe was easy to follow and it was delicious!!


Thank you Marti! Gad you liked it!

Oops! Between the cream cheese and sweet onion add your layer of thinly sliced fish (about 1/16″ vertical slice). I’ve smoked with all the fruit and nut woods and find pecan to be my favorite for fish. please visit:
