Poblano, Potato, and Corn Gratin

This vibrant poblano, potato and corn gratin is a sophisticated vegetarian takes on a classic comforting side dish. The mild, smoky heat of the poblano chillies provides a wonderful contrast to the natural sweetness of the corn kernels and the buttery finish of the potatoes. It is a hearty bake that brings a touch of Mexican-inspired flavour to the table, making it a brilliant alternative to a traditional potato dauphinoise or cauliflower cheese.

Perfect as a substantial side for a Sunday roast or as a standalone vegetarian main served with a crisp green salad, this dish is wonderfully versatile. Using single cream and a touch of flour creates a silky, savoury sauce that binds the layers together beautifully without being overly heavy. It is an excellent choice for a family dinner or a weekend gathering when you want something homemade and deeply satisfying.

Ingredients for Poblano, Potato, and Corn Gratin

  • 3 teaspoons olive oil, divided

  • 2 large fresh poblano chillies,* stemmed, seeded, cut into 2 x 1/4-inch strips

  • 575g Yukon Gold potatoes, peeled, cut into 1/8-inch-thick rounds

  • 240ml coarsely grated Oaxaca cheese or whole-milk mozzarella cheese, divided

  • 350ml half cream

  • 2 tablespoons plain flour

  • 3/4 teaspoons salt

  • 1/2 teaspoons freshly ground black pepper

Preheat oven to 204°C. Rub 9 1/2-inch-diameter deep-dish glass pie dish or cast-iron skillet with 2 teaspoons oil. Heat remaining 1 teaspoon oil in large nonstick skillet over medium-high heat. Add poblano strips and sauté until tender, about 5 minutes. Remove from heat.

Repeat with 1/3 of potatoes, 1/3 of poblanos, 1/3 of corn, and 1/3 of cheese. Top with remaining potatoes, poblanos, and corn, reserving remaining 1/3 of cheese. Place pie dish on rimmed baking sheet.

Cover dish tightly with foil. Bake 30 minutes. Remove foil; sprinkle remaining cheese over gratin. Continue to bake gratin until potatoes are tender and cheese is golden brown, about 25 minutes longer. Let stand 10 minutes before serving.
