Baked Cod and Potatoes is a simple, delicious dish featuring cod fillets roasted on top of buttery, crispy, well-seasoned potato slices.
- 2 large russet potatoes (about 1 pound) or 3 medium
- ¼ medium yellow onion thinly sliced
- 2 Tablespoons butter melted
- 2 Tablespoons extra virgin olive oil
- salt and pepper to generously season potatoes
- garlic powder to generously season potatoes
- paprika to generously season potatoes
- ¾ pound cod fillets (3 fillets) approx. 1" thick and 4 oz. each
- fresh thyme leaves (chopped) to lightly season fish
- additional salt (optional) to lightly season fish
-
Preheat oven to 400℉. Grease or spray bottom of a 9" square baking dish.
-
Wash and peel potatoes. Slice potatoes into 1/8" thick rounds using a knife or mandoline. Place potato slices in a bowl.
-
Combine melted butter and olive oil in a separate bowl. Remove 1 Tablespoon of mixture; set aside (to drizzle on fish later). Pour remaining butter/oil mixture on potatoes; toss well until potatoes are coated. Spread potatoes in prepared dish, in a single layer. Season generously with salt, pepper, garlic powder and paprika.
-
Bake the potatoes at 400°F. for 35-40 minutes until softened and light golden brown in color. Flip slices over halfway through baking time, then re-spread them in the dish; continue baking. TIP: Check on potatoes 2-3 times while they bake so they don't get too crispy.
-
Remove potatoes from oven. Turn on the BROILER: move oven rack to 6" below broiler heat source. Place cod fillets on top of potatoes. Drizzle reserved butter/oil mixture over the fish. Lightly sprinkle fish with additional salt (if desired), then sprinkle with fresh thyme leaves.
-
Put baking dish under broiler (6" away from heat source). Broil 7-10 minutes OR until fish is cooked through (flakes easily with a fork), and potatoes are crispy/browned. Time may vary depending on thickness of fish. TIP: Keep an eye on everything as it broils. If potatoes begin to burn, move baking dish further away from the broiler!
-
Remove from oven; serve immediately. Serve fish on top of the potatoes or with potatoes on the side. Enjoy!
