How to Make Whole Roasted Fish with Rosemary Potatoes – Step by Step

Preparing the Potatoes

Step 1: Preheat your oven to 425°F (220°C). This high temperature will help create perfectly crispy rosemary roasted potatoes and ensure the fish cooks quickly without drying out.

Step 2: Place the potato cubes in a large roasting pan. Drizzle with 1-2 tablespoons of olive oil, sprinkle with salt, pepper, crushed red pepper (if using), and add the garlic and rosemary sprigs designated for the potatoes.

Step 3: Toss everything together to coat the potatoes evenly, then spread them out in a single layer for even cooking.

Step 4: Roast the potatoes for 15 minutes until they begin to turn golden but aren’t completely cooked through.

Preparing the Fish

Step 5: While the potatoes are roasting, prepare your fish. Rinse each fish under cold water and pat dry thoroughly with paper towels—this helps ensure crispy skin when roasted.

Step 6: Using a sharp knife, make 2-3 diagonal slashes on each side of the fish, cutting about ¼-inch deep. This allows the flavors to penetrate and helps the fish cook evenly.

Step 7: Season the cavity of each fish generously with salt and pepper. Stuff each cavity with garlic, rosemary sprigs, and 2-3 lemon slices.

Roasting Together

Step 8: Remove the potatoes from the oven and create spaces for the fish. Place the prepared fish on top of or alongside the partially roasted potatoes.

Step 9: Drizzle the fish with the remaining olive oil and season the outside with salt and pepper.

Step 10: Return the pan to the oven and roast for 12-15 minutes, or until the fish is opaque and flakes easily with a fork and the potatoes are golden and crispy.
