Preheat your oven to 400F. Place the cod in a baking dish.
In a small bowl, mix the butter, olive oil, minced garlic, parsley, paprika, salt, and pepper.
Spread the mixture on top of each filet.
Lay the lemon slices both on top and under the cod filets.
Bake in the oven for 13-15 minutes, or until the cod is opaque and flakes easily with a fork. Do not overcook.
Before serving, spoon the juices from the baking dish over the cod.
Enjoy with orzo pasta drizzled with olive oil, lemon juice, and a touch of salt.
