I know I'm too late to help you this time around, but just in case you want to keep this on hand for future Bluefish feasts, one of my favorite ways of cooking them is a "Greek-style" recipe my mom always makes.
Just place the filets, skin-side down, on an oiled baking sheet & top with very thinly sliced tomato, generous sprinklings of dried oregano, some fresh ground black pepper, sliced rings of red onion, & a generous amount of crumbled feta cheese. Finish with a drizzle of olive oil & some fresh lemon juice. Bake at 450 until fish flakes/is cooked through.
Serve with a nice big Greek salad & your favorite rice dish.
(Any leftover bluefish makes a wonderful salad the next day mixed with a little mayonnaise to bind.)
