I made this with cod fillets.

450 degree oven

6 fish fillets (any kind) in a non-aluminum shallow dish

Whisk this marinade in a small bowl:
1/4 cup fresh lemon juice
2 tbsp melted butter or olive oil
2 tbsp Dijon mustard
2 tbs chopped fresh dill or 1 tsp dried dill
1/2 tsp salt
Freshly ground black pepper to taste

Pour 1/2 the marinade over the fish, cover with plastic wrap, and let it sit for 10 minutes

Transfer the fish to a baking sheet and bake till done - 6 to 9 minutes

Drizzle remaining marinade over fish to serve.


I even liked it as warmed up leftovers!

That sounds delicious. Mustard is great with fish. Sometimes I just brush the filets with Dijon mustard and broil them, with a squeeze of lime when they are done and a sprinkle of chopped coriander.
