Preheat oven tp 400℉
Lay the Cod Fillets on a baking sheet or low-rimmed baking dish. Season with Salt and Pepper. Lightly sprinkle with Paprika. Set aside.
Place the room temperature Butter and Dill in a small bowl. Using a spoon, smoosh the dill into the butter until mixed completely.
Add the Olive Oil and mix in to make the dill butter more spreadable.
Divide the Dill Butter Mixture between the two cod fillets.
Using your fingers or back of a spoon, spread the dill butter over the cod.
Cut several thin slices from the lemon and lay over the dill butter. Keep remaining portion of the lemon to squeeze over finished cod.
Pop into the oven and bake for 15-20 minutes - until fish is flakey. Time will vary based on the thickness of your fish fillets. If you feel the need to check, it will be done when the internal temperature is at 145℉
Remove from oven. Using a fish spatula, move fillets to plate. To serve, set lemon slices to side and spoon the pan sauce over the fish. Finish off with a squeeze of lemon. Enjoy.
