Prepare the ingredients: Pat the fish filets dry with paper towels. Squeeze the lemon juice, cut a half a lemon into wedges and drain the artichokes if you are using canned. Preheat the oven to 350 degrees f.
Melt the butter in a heavy skillet (cast iron works best) over medium heat. Once melted, add the garlic and lemon juice; add the fish filets and flip them around in the garlic butter mixture to coat them with the sauce.
Scatter the artichokes and lemon wedges around the fish in the pan. Bake until the fish reaches an internal temperature of 145 degrees - about 20 minutes.
Notes
TIPS:
Use room temperature fish– Let the fillets sit out at room temperature about 10 to 15 minutes before cooking to ensure even cooking.
Use a meat thermometer -To avoid overcooking the cod, insert it into the thickest part of the fish. Remove the fish from the oven once it reaches 145 degrees.
