Well, I grew up with a trout stream under our driveway bridge but it was all little native brownies that averaged about ten inches but would sometimes get up to 15 or 16 inches so we seldom filleted them. I can't stand fish with the skin or the head on either so our standard recipe was to skin 'em, sprinkle with Lawry's Season Salt and fry them in butter until they'd get a little crispy. Dang were they ever good!
In later years, I've gotten a little more advanced with my cooking... Actually, those little trout were the first thing I ever learned to cook for myself because Mom didn't like messing with them. I still love them cooked that way but frying unbreaded fish until it gets crispy is about like frying bacon... it shrinks a bunch! My latest fish cooking "discovery" came about by accident but you might like it.
We were going to fry up some Tilapia about a year ago. Normally for it, we'd sprinkle with lemon pepper and dust in flour with some seasoning in it then leave sit for a few minutes and dip again then fry in a cast iron pan with about 1/4" of cooking oil on medium heat. Add a side of home made fries or something like a rice dish and maybe asparagus and it's a pretty good yet easy feed. This particular day, I got the fish all thawed, sprinkled on the lemon pepper and opened the cupboard only to find we were slap out of flour. Well heck I thought, there must be something I can bread it with... I started going through the cupboards and happened upon a box of the Gerber baby rice cereal. You know, the stuff that looks like little shiny flakes that are almost a clear whitish color and you mix it with a little milk or put in the baby's formula.
I thought hey, that might work! I poured some out on a plate and dredged the fillets through it dry a couple times and threw them in the pan. Well, I'll tell ya what! It's a pretty darned good breading. About as light and delicate as you could ask for yet it seals the fish and keeps it from shrinking about the same as regular breading and gives a nice crispy coating without drying up the fish like when you fry it naked till crispy.
Try doing your trout with a sprinkle of Lawry's season salt and then roll them in the baby rice cereal stuff and fry them up. Cajun spice or creole seasonings like the Tony Cachere's stuff would be real good too. It don't get much simpler than that and it's good too.
