Cast-Iron Roasted Clams

This rustic roasted clams dish is a vibrant, dairy-free meal that brings the fresh flavours of the coast to your kitchen. By roasting small, hard-shelled clams on a bed of sweet red onions, tender potatoes, and blistered plum tomatoes, you create a natural sauce that is rich with garlic and a hint of chilli heat. The cast-iron method ensures a beautiful caramelisation on the vegetables while gently steaming the seafood to succulent perfection.

Perfect for a relaxed weekend lunch or a Mediterranean-style dinner, this one-pan recipe is as impressive as it is effortless. The combination of heart-healthy olive oil and mineral-rich shellfish makes it a nutritious choice for those seeking a lighter savoury meal. Serve the pan directly at the table with some crusty bread to soak up the delicious juices.

Ingredients for Cast-Iron Roasted Clams

  • 1.4kg medium (3- to 4-inch) red potatoes

  • 3 small red onions (350g total), quartered lengthwise, leaving root end intact

  • 120ml extra-virgin olive oil

  • 1 teaspoon salt

  • 1/2 teaspoons black pepper

  • 800g plum tomatoes (10 to 12), halved lengthwise

  • 40 small hard-shelled clams (1.8kg) such as littlenecks (less than 2 inches wide), scrubbed well

  • 1/2 teaspoons dried hot red pepper flakes

  • 1/4 cup chopped fresh parsley

  • a 14-inch cast-iron skillet with lid, or a 17- by 12-inch heavy roasting pan (preferably dark metal) and heavy-duty foil

How to make Cast-Iron Roasted Clams

Preheat oven to 260°C.

Cut potatoes into 1/2-inch-thick slices and toss with garlic, onions, oil, salt, and pepper in skillet (or roasting pan). Roast in middle of oven until potatoes begin to brown, about 15 minutes. Add tomatoes, tossing to combine, and roast until skins wrinkle and split, about 10 minutes. Add clams and red pepper flakes and roast, covered with lid (or tightly covered with foil), until clams are fully open, 6 to 10 minutes. (Discard any clams that have not opened after 10 minutes.) Sprinkle with parsley and serve in skillet.
