Tilapia in coconut milk

I made this recipe up. It's the best preparation of tilapia I've had in a while.

Put 1 cup coconut milk into 9x13 dish. Set 4-6 tilapia fillets into the milk (1 - 1.5 lb), getting it onto both sides of the fish.
On top of the fish, sprinkle dried chopped onion, tarragon, salt, and pepper. Then I sprayed some olive oil pam on top of the fish to moisten the herbs. I'm not sure if that step was necessary.

Bake at 350 for 15 minutes. Or something. I didn't set the timer. I used 6 tilapia and they were all touching.
