Cod with Potatoes and Onions

Step 1

Preheat oven to 400°F. Slice 1.5 lb potatoes into 1/4-inch rounds and 2 onions into thin half-moons.

Step 2

In a large oven-safe skillet, heat 2 tbsp olive oil over medium. Add potatoes and onions, season with 1/2 tsp salt and 1/4 tsp pepper, and cook, stirring occasionally, until onions are soft and potatoes are slightly tender, about 10 minutes.

Step 3

Nestle 1.5 lb cod fillets among the potatoes and onions. Drizzle with remaining 2 tbsp olive oil and sprinkle with 1/2 tsp salt and 1/4 tsp pepper.

Step 4

Transfer skillet to oven and bake until cod is opaque and flakes easily with a fork, and potatoes are fork-tender, about 15-20 minutes.

Step 5

Scatter 1/2 cup black olives over the top and return to oven for 2 minutes to warm through.

Step 6

Remove from oven and sprinkle with 1/4 cup chopped parsley. Serve hot directly from the skillet.
