Lemon Butter Fish Fillet Recipe FAQs
How fresh should the fish be for the best Lemon Butter Fish Fillet?
Freshness is key! Choose firm, mild-flavored white fish fillets like cod or tilapia that have a clean scent and moist texture. Avoid fillets with dark spots or a strong fishy odor, as these indicate they’re past their prime.
Can I store leftover Lemon Butter Fish Fillet, and how long will it keep?
Absolutely! Store leftovers in an airtight container in the fridge for up to 3 days. To keep the fillets from getting soggy, place a piece of parchment paper between the fish and the lid to absorb extra moisture—this little trick keeps your fillets tasting fresh and flaky.

When ready, thaw overnight in the fridge for the best texture. I recommend reheating gently in a skillet over low heat to keep the delicious buttery sauce intact.
What if my lemon butter sauce turns bitter or too tart?
This can happen if lemon juice is cooked too long over heat. To avoid that, add fresh lemon juice and zest off the heat at the very end. If bitterness occurs, balance it by stirring in a tiny bit more melted butter or a pinch of sugar to mellow out the sharpness.
