Instructions

  1. 1

    Flip fillets and repeat with remaining lemon juice, pepper, and oregano.

  4. 4

    Heat a large skillet over medium heat and lightly spray with oil.

Tips

Tip 1

Pat the fish completely dry after thawing to ensure proper browning and prevent sticking in the pan.

Tip 2

Don't flip the fish more than once; keeping it undisturbed allows the exterior to develop better contact with the pan.

Good to Know

Storage

Keep leftover cooked fish in an airtight container in the refrigerator for up to 2 days. The tomato mixture may soften the fish texture upon reheating.

Make Ahead

Season the fish and chop vegetables up to 4 hours in advance. Store separately. Do not cook the fish ahead; best served fresh.

Serve With

Plate the fish with the tomato-jalapeno mixture spooned over top. Serve immediately with steamed rice, pasta, or crusty bread to soak up juices.

Common Mistakes

Watch

Do not skip patting the fish dry to avoid sticking and ensure browning.

Watch

Do not cook at high heat to avoid the exterior burning before the fish cooks through.

Watch

Do not overcrowd the skillet to avoid steaming instead of searing.

FAQ

Can I use frozen basa without thawing?

No. Thaw completely in the refrigerator overnight or under cold running water. Frozen fish releases excess moisture that prevents proper searing and overcooks the exterior before the center is done.

What if I don't have fresh jalapenos?

Substitute with canned diced jalapenos or skip entirely for a milder dish. Dried red pepper flakes at 0.25 teaspoon offer heat without fresh pepper texture.

How long can I keep leftovers?

Refrigerate in an airtight container for up to 2 days. Basa becomes dry when reheated; gently warm in a low oven or eat chilled over salad instead.
