There are certain dishes that, when you make them, just transport you. Julia Child’s Zucchini and Rice Gratin, or Tian de Courgettes au Riz as it’s known in French, is one of those culinary journeys. This isn’t your everyday zucchini casserole. It’s elegant, surprisingly hearty, and bursting with simple, fresh flavors.

Preparation and Cooking
The process of making this gratin is quite straightforward, but each step contributes to the final wonderful result. It’s about coaxing the best flavors out of each ingredient.
1. Preparing the Zucchini: Begin extract by washing your zucchini thoroughly. Trim off the ends. You’ll want to slice the zucchini into thin rounds, about 1/8 to 1/4 inch thick. The key here is consistency in slicing so they cook evenly. Some recipes call for salting and draining the zucchini to remove excess moisture, which is a good practice to prevent a watery gratin, especially if your zucchini are particularly watery. For this recipe, I find that simply slicing them thinly and ensuring they have a chance to dry slightly on paper towels before layering is usually sufficient. If you’re concerned about moisture, you can always spread the slices on a clean kitchen towel or paper towels for about 15-20 minutes.
2. Cooking the Rice and Aromatics: In a medium saucepan, cook the white rice according to package directions. While the rice is cooking, heat 2 tablespoons of the olive oil in a large skillet over medium heat. Add the minced onions and sauté them until they are softened and translucent, which should take about 5-7 minutes. Don’t rush this step; sweet, softened onions are crucial for flavor. Then, add the minced garlic to the skillet and cook for another minute until fragrant, being careful not to burn it. Once the rice is cooked and drained, stir it into the skillet with the onions and garlic. Season this mixture generously with salt and freshly ground black pepper. Set aside.
3. Creating the Sauce Base: In the same skillet (or a separate small saucepan if you prefer), melt the remaining 3 tablespoons of olive oil over medium heat. Sprinkle in the all-purpose flour and whisk it constantly for about a minute to cook out the raw flour taste. This is your roux. Gradually whisk in about 1/4 cup of milk, ensuring it’s smooth and lump-free. Continue to add the milk a little at a time, whisking continuously, until you have a smooth, thickened sauce. You might not need the entire 1/2 cup of milk; the consistency should be like a thin bécbeef hamel. Season this sauce with salt and pepper. Stir in half of the grated Parmesan cheese (about 1/3 cup), allowing it to melt into the sauce. This creates a lovely, cheesy base that will bind the gratin beautifully.
4. Assembling the Gratin: Preheat your oven to 375°F (190°C). Lightly grease a gratin dish or a similar-sized baking dish with a little olive oil or butter. Now, it’s time to assemble. You have a couple of options here: you can layer the zucchini and rice mixture, or you can gently mix them together before layering. I often find a gentle toss in a large bowl works well to distribute the rice and onion mixture evenly among the zucchini. Then, spread about half of the zucchini slices in an even layer in the prepared gratin dish. Spoon half of the rice and onion mixture over the zucchini. Drizzle about half of the cheese sauce over this layer. Repeat with the remaining zucchini, rice mixture, and cheese sauce. Ensure the top layer of zucchini is nicely arranged.
5. Baking to Perfection: Sprinkle the remaining 1/3 cup of grated Parmesan cheese evenly over the top of the gratin. Cover the gratin dish tightly with aluminum foil. Bake for 30 minutes. After 30 minutes, remove the foil and continue to bake for another 20-25 minutes, or until the top is golden brown and bubbly, and the zucchini is tender. You can test for doneness by gently piercing a slice of zucchini with a fork; it should yield easily. The aroma that fills your kitchen during this final baking stage is absolutely divine! Allow the gratin to rest for about 5-10 minutes before serving. This brief resting period allows the flavors to settle and makes it easier to serve. This Zucchini and Rice Gratin is a wonderful side dish to grilled meats, chicken, or fish, and it’s also satisfying enough to stand on its own as a light vegetarian main course. Enjoy this taste of Julia’s culinary magic!

Frequently Asked Questions:
Can I make this ahead of time?
Yes, you can assemble the gratin a day in advance. Cover it tightly with plastic wrap and refrigerate. When ready to bake, remove it from the refrigerator about 30 minutes before baking to allow it to come closer to room temperature, and you may need to add a few extra minutes to the baking time.
What kind of rice is best for this recipe?
While a medium-grain white rice works beautifully, you could also experiment with arborio rice for a creamier texture, or even a wild rice blend for added nuttiness and visual appeal. Ensure your rice is cooked al dente before assembling, as it will continue to cook in the oven.
My zucchini seems to be releasing a lot of water. What should I do?
This is a common occurrence with zucchini! To combat excess moisture, you can lightly salt the sliced zucchini and let it sit in a colander for about 30 minutes, then gently pat it dry with paper towels before layering it into the gratin. This helps draw out some of the water and will prevent your dish from becoming watery.
