Sheet Pan Baked Cod on Crispy Garlicky Potato Rafts

This sheet pan cod is baked on crispy and garlicky rafts of thinly sliced potatoes and topped with lemon, thyme, and capers. 

Sheet Pan Cod on Crispy Garlicky Potato Rafts

This recipe for the crispy and garlicky potatoes topped with cod is easy to assemble and bake in the oven.
All you need to do is thinly slice the potatoes, toss them in olive oil, garlic, salt, and pepper, and then arrange them on a baking sheet by overlapping the slices in shingled rows. 

Thinly sliced russet potatoes and garlic

I used this mandoline to thinly slice the potatoes. If you're really good at thinly slicing potatoes with a knife, you don't necessarily need a slicer, but this one made fast work of slicing the potatoes. I bought it a few years ago after seeing it recommended by Cook's Illustrated. 

Plus, I never met a kitchen gadget I didn't like. 

After you've sliced and arranged the potatoes on your sheet pan, you bake them all by themselves in a 425 degree F oven for 30 minutes. Next, you top them with the fish, butter, some lemon slices, thyme, and capers, and bake them for about 15 minutes more, until the potatoes are all crispy and the fish is just cooked through and flaky.

Once I pulled these cod and potato rafts from the oven, it was really hard for me not to pick away at the edges of the potatoes for extra tastes before serving them. They were kind of like crispy tender garlicky warm potato chips..... soooo good and exactly what I was craving. 

I loved, loved, loved these baked cod and potato rafts. I only used 4 ounces of cod per serving, but you could easily double that if you'd like more fish. You won't regret making this dish. 

You can also substitute sole, haddock, or halibut for the cod if you prefer. This recipe is super flexible. 

I never really associate fish with potatoes, with the exception of fish and chips. This dish kind of takes fish and chips to another level!

This is such an easy dish to make. Serve it with a salad and dinner rolls and you have an elegant and delicious dinner. It's scalable and perfect for dinner for two or four. Your guests will love you.
