This vibrant corn and tomato gratin is a wonderful way to celebrate the produce of late summer. Combining juicy, thick-sliced tomatoes with sweet corn kernels simmered in a rich cream sauce, this vegetarian dish offers a beautiful contrast of textures. The addition of fresh basil and a golden parmesan breadcrumb topping provides a savoury, aromatic finish that elevates the natural sweetness of the vegetables.
Serve this comforting gratin as a substantial side dish for a Sunday roast or as a light main course alongside a crisp green salad.

It is an excellent choice for alfresco dining or a family gathering, providing a sophisticated yet simple homemade meal that everyone will enjoy.

How to make Corn and Tomato Gratin
Arrange tomato slices in 1 layer on a rack set in a shallow baking pan and sprinkle on both sides with 1 teaspoon salt and 1/2 teaspoons pepper. Let drain 30 minutes.
While tomatoes drain, bring corn, milk, cream, and 1/4 teaspoons salt to a simmer in a 2- to 3-quart heavy saucepan over high heat, then reduce heat and simmer, partially covered, until corn is tender, about 5 minutes. Cool slightly, uncovered.
Put oven rack in upper third of oven and preheat oven to 191°C. Butter a shallow 2-quart baking dish.
Toss together bread crumbs, basil, cheese, and remaining 3/4 teaspoons salt and 1/2 teaspoons pepper in another bowl.
Arrange one third of tomato slices in baking dish, then cover evenly with one third of bread-crumb mixture and dot with one third of butter. Spoon half of corn mixture over crumbs, then repeat layering with half of remaining tomatoes, crumbs, and butter, and all of corn. Arrange remaining tomatoes over corn, then top with remaining bread crumbs and dot with remaining butter.
Bake, uncovered, until top is golden and gratin is bubbling all over, 40 to 45 minutes. Cool slightly on a rack, about 15 minutes, before serving.
