Seriously, I’m not sure how these flounder fillets made it into my freezer.  I never buy flounder. Maybe my hubby mistakes them for tilapia on one of the many foods runs I send him on. Oh well, they came in handy last night when I needed a quick dinner.

This lemon cajun flounder recipe is so basic. I hesitated to post it, but what the heck right? You never know who is out there in the blogosphere searching for ways to prepare flounder fillets. Well here’s how I did mine: lemon, cajun seasoning, old bay, and onion powder.  BAM! Yep, that’s it. Sounds too easy right? Now you see why I almost didn’t post this recipe.

These little flounder fillets pack a hot, spicy, lemony punch and pairs well with plain rice and steamed veggies. This recipe is pretty much fail-proof. I never measure the spices, just coat the fish well and it all seems to work out.  I think these lemon cajun flounder fillets would look beautiful and “Springy” placed on a platter and garnished with lemon slices and fresh green herbs. No one would ever believe how easy they were to make.
