Courgette Rice Gratin

This Mediterranean-inspired courgette rice gratin is a wonderful way to celebrate seasonal produce. By roasting the courgettes and plum tomatoes before assembly, the vegetables develop a concentrated sweetness that pairs beautifully with fragrant thyme and salty Parmigiano-Reggiano. The rice adds a satisfying structure, creating a dish that sits somewhere between a savoury cake and a classic French vegetable tian.

As a versatile vegetarian main or a substantial side dish for roasted meats, this bake is both nutritious and comforting. The combination of slow-cooked onions and a golden cheese crust makes it a popular choice for light summer lunches or a healthy mid-week supper. Serve it warm from the oven with a crisp green salad to balance the rich, savoury flavours of the roasted vegetables.

How to make Courgette Rice Gratin

Preheat oven to 232°C with racks in upper and lower thirds.

Cook rice according to package instructions.

While rice cooks, toss courgette with 1 tablespoon oil and 1/2 teaspoons salt in a shallow baking pan. Toss tomatoes with 1/2 tablespoons oil and 1/4 teaspoons salt in another baking pan.

Roast courgette in upper third of oven and tomatoes in lower third, turning vegetables once halfway through roasting, until tender and light golden, about 10 minutes for tomatoes; 20 minutes for courgette. Leave oven on.

Meanwhile, cook onion and garlic with 1/2 teaspoons salt in 2 tablespoons oil in a large heavy skillet, covered, over low heat, stirring occasionally, until very tender, 15 to 20 minutes.

Stir together onion mixture, cooked rice, eggs, thyme, 60ml cheese, 1 tablespoon oil, 1/4 teaspoons salt, and 1/2 teaspoons pepper. Spread half of rice mixture in a shallow 2-quart baking dish, then top with half of courgette. Spread remaining rice mixture over courgette, then top with remaining courgette. Top with tomatoes and drizzle with remaining 2 tablespoons oil, then sprinkle with remaining 30g cheese.

Bake in upper third of oven until set and golden brown, about 20 minutes.
