Looking for a fish recipe

Probably 10-12 years ago, maybe a little more, me and a buddy of mine got into some trout in big lake. That night his dad cooked from a recipe I recall him saying he found in Louisiana sportsman. It was trout filets on a sheet pan and had heavy cream, butter, maybe red onions and lemon (at least). It was all put together on the sheet pan and baked. Served over baked potatoes and it was delicious. I’ve never been able to find the recipe and I’m wondering if anyone has any similar recipe or maybe happens to know what I’m talking about. Never occurred to me to ask the great Food and Drink board before now
