Melt butter, sauté onion until clear.

Meanwhile, mix cheese, bread crumbs, and parsley in a small bowl.

Set aside ¼ cup of this mixture.

Then add vermouth to sautéed onions and butter; pour half of the mixture into the larger quantity of bread crumb mixture; stir lightly with fork.

Stuff fish with mixture.

Brush fish with remaining butter mixture.

Sprinkle reserved bread crumbs over fish.

Drizzle with any remaining butter over this and bake 20-25 minutes at 350º in a flat open pan.

Fish should flake easily when done.

Paprika can be used over top of fish to aid in browning.

Growing up my family enjoyed this quite often, as we had two great trout streams that ran through the ranch.
