Preparation
Step 1
Preheat oven to 400°F. 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.
Step 2
Arrange 1/3 of potato rounds, overlapping slightly, in prepared pie dish. Sprinkle 1/3 of poblano strips over, then 1/3 of corn and 1/3 of cheese. 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.
Step 3
Whisk half and half, flour, 3/4 teaspoon salt, and 1/2 teaspoon freshly ground black pepper in small bowl. Pour over potato mixture in pie dish; press potatoes to submerge. 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.
