Light and lemony baked basa fillets are delicious and pretty with this quick and easy recipe, which is ready in 25 minutes.

This healthy recipe works well with many types of white fish, including mahi mahi, swai, and tilapia. It even works on baked lemon pepper chicken. But it is spectacular on basa!
I pick this fish up at my local supermarket—it's not exotic or hard to find. It has a moist, lightly firm texture and a very mild fish flavor, which is why it's so popular. It easily soaks up the lemon, butter, and spices in this recipe.
I partnered with Darlene Hardister-Heumann, author of The Southern Sass Cookbook: It's All in the Sass!, and offered it at our meal assembly stores. It was a hit!
It's such a tried-and-true combination that I have yet to find a fish it doesn't pair well with. Be sure to check out our baked corvina recipe and lemon pepper tilapia, which share the same ingredients.

Ingredient Notes
Here's what you'll need to make this easy baked basa fillet recipe:

Of special note:
- Basa fish fillets - Other mild white fish with a taste and texture similar to basa are catfish, flounder, or haddock.
- Lemon-pepper seasoning gives basa fish a zesty lemon flavor. If you enjoy this flavor profile, you won't regret keeping this spice blend on hand. Use it to quickly brighten the flavor of everything from zucchini to shrimp.
- Herbs and lemon - This dish's fresh feel is owed to chopped green onions, parsley, and, of course, freshly squeezed lemon. Leave them off in a pinch, and add extra as garnish when company is coming.
If you're in the mood for something with a little heat, you might also love cajun catfish. This fish happens to be a cousin to basa!

Directions with Pictures
Here's how to cook basa fillets in the oven:

Step 1
Pat fish fillets dry and place them in a baking dish coated with cooking spray or a rimmed sheet pan.

Step 2
Pour lemon juice and melted butter over the fish. Next, sprinkle garlic powder, lemon pepper seasoning, paprika, chopped parsley, and green onion over the fish.

Step 3
Bake uncovered at 425°F for 10-12 minutes or until the basa flakes with a fork. The exact timing will vary based on the thickness of the fillets.
Top Tips
- For better control, use your fingers to sprinkle the seasoning. This method allows you to spread the seasoning more uniformly over the fish's surface.
- Cook fish to an internal temperature of 145°F. The flesh will be opaque and separate easily with a fork. Use a food thermometer to check the internal temperature at the thickest part of the fish.

What to Serve with Basa Fillets
I like to pair lemony baked basa with simple sides, such as Southern vinegar coleslaw and mashed cauliflower from frozen. These sides take minutes to make and keep the meal low-carb.
Recipe FAQs
When cooking basa fish from frozen, you generally need to add about 5-10 minutes to the usual cooking time compared to when it's fresh. So, if you're baking the fish at 425°F and it usually takes 10-12 minutes from fresh, you should aim for about 15-20 minutes from frozen.
Basa fish can become mushy if it is overcooked or thawed improperly, such as on the counter or under running water. Cook basa to an internal temperature of 145°F and defrost in the refrigerator or cook from frozen. Quick cooking methods, such as broiling or grilling, also help maintain the firm texture.
Store leftover basa in an airtight container. Refrigerate it for up to 3 days or freeze it for up to 2 months. To reheat, use a gentle method like microwaving on low power or warming in the oven at 275°F until heated through to preserve its texture.

This was delicious. A few cracks of black pepper really brings the flavour out and accents the lemon nicely.

This recipe looks just right for me. I'm having a dinner party in a couple of days. I'm wondering about how to deal with frozen basa fillets. They are stuck together a bit. I've usually cooked frozen fish without thawing first. I'm thinking to just thaw these enough to get them separated. I'll just toss a crushed garlic clove into the butter as I melt it as I don't have powdered garlic. Do you think that would work?
Marjory says
Yes! Sounds like a good plan. 🙂
Lisa says
The fish didn't cook. I had it on 425 degrees for the recommended time - centre was still raw. I kept putting it on an additional 5 minutes at a time - 15 minutes later, still raw in the centre. I ended up wrapping it in foil and finishing it that way. No idea why this didn't work for me, but it was awful.
Marjory says
It's really hard to tell exactly what might have been the problem as the size of the fish, acutal oven temperature, etc. vary so much. I'm so sorry it didin't work out. 🙁
Lori Porter says
Mine aswell. I ended up putting it in for an additional 12 mins and then it wasn't slimy and nothing but delicious!!!
Kirk says
I don't mean to degrade any comments but make sure you preheat ovens before cooking anything. I found it to be best at 425 for 20 mins.
