Oil the bottom of a porcelain baking dish with a little olive oil to prevent sticking. Place fillet in baking dish and pour over a thick mixture of olive oil, lemon juice, minced garlic. Sprig of dill on top and cover fish with very thin slices of lemon.
Bake with dish loosely covered in aluminum foil for 15-18 min. [approx time for a 1 1/4" fillet] @ 400-425 deg. Check doneness - med rare pink inside is GOOD! Sometimes taking the foil off for last few minutes is a good idea. Basting with dish juices about halfway through is also good idea.
Use WILD fish - farm raised are junk.
Thanks.
