Cooking Instructions:
Preparing the Zucchini
The first step in creating this wonderful gratin is to prepare our star ingredient: the zucchini. You’ll want to wash your zucchini thoroughly and then trim off the ends. The key here is how you cut them. We want thin, uniform slices, about 1/8-inch thick. This can be achieved with a sharp knife and a steady hand, or if you have one, a mandoline slicer is your best friend for achieving that perfect consistency. Uniformity is important because it ensures that the zucchini will cook evenly throughout the gratin, preventing some pieces from becoming mushy while others remain slightly undercooked. As you slice them, you’ll notice a bit of moisture. You can lightly salt the zucchini slices and let them sit in a colander for about 15-20 minutes to draw out some of that excess water. This step is not strictly necessary, but it can help prevent the gratin from becoming too watery. Gently pat them dry with paper towels before proceeding.
Cooking the Rice and Aromatics
Next, we turn our attention to the rice and the flavor base. In a medium saucepan, combine the 1/2 cup of uncooked white rice with 1 cup of water and a pinch of salt. Bring it to a boil, then reduce the heat to low, cover, and simmer for about 15 minutes, or until the water is absorbed and the rice is just tender. We don’t want the rice to be fully cooked, as it will continue to cook in the oven. Once cooked, fluff the rice with a fork and set it aside. While the rice is cooking, let’s build our flavor foundation. In a large skillet, heat 3 tablespoons of the olive oil over medium heat. Add the minced onions and sauté them until they are softened and translucent, which should take about 5-7 minutes. You want them to be sweet and tender, not browned. Stir in the minced garlic and cook for another minute until fragrant, being careful not to burn it.
Creating the Creamy Sauce
Now, we’ll create a simple yet elegant sauce to bind everything together. To the skillet with the softened onions and garlic, sprinkle in the 2 tablespoons of all-purpose flour. Whisk it well with the onions and oil, cooking for about 1 to 2 minutes to toast the flour slightly. This process, known as making a roux, will help thicken our sauce and prevent a raw flour taste. Gradually whisk in the 1/2 cup of milk. Keep whisking constantly to avoid lumps. Continue to cook, stirring, until the sauce thickens to a smooth, creamy consistency. You may need to add a little more milk, a tablespoon at a time, if the sauce becomes too thick. Season generously with kosher salt and freshly ground black pepper to taste. Remember that the Parmesan cheese will also add saltiness, so be mindful of that when seasoning. Stir in about half of the grated Parmesan cheese (approximately 1/3 cup) into the sauce until it’s melted and well combined.
Assembling the Gratin
It’s time to bring all our components together! Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Lightly grease a gratin dish or a similar-sized baking dish with the remaining 2 tablespoons of olive oil. In a large bowl, gently toss the sliced zucchini and the partially cooked rice together. Pour the creamy onion and garlic sauce over the zucchini and rice mixture. Gently fold everything together to ensure that the zucchini slices and rice are evenly coated with the sauce. Be careful not to overmix, as we want to maintain the integrity of the zucchini slices. Pour the mixture into the prepared gratin dish, spreading it out evenly.
Baking to Golden Perfection
Finally, we bake this delicious creation. Sprinkle the remaining 1/3 cup of grated Parmesan cheese evenly over the top of the gratin. You can also add an extra grind of black pepper if you like. Cover the gratin dish loosely with aluminum foil. Place it in the preheated oven and bake for about 30 minutes. After 30 minutes, remove the aluminum foil and continue to bake for another 20-25 minutes, or until the top is beautifully golden brown and the zucchini is tender when pierced with a fork. The edges should be bubbling, and the aroma filling your kitchen will be absolutely divine. Allow the gratin to rest for about 5-10 minutes before serving. This brief resting period allows the flavors to meld and the gratin to set slightly, making it easier to serve. Enjoy this delightful taste of Julia Child’s culinary brilliance!

For serving, this gratin is incredibly versatile. It pairs wonderfully with roasted chicken or fish, but it also stands beautifully on its own as a light vegetarian main course. Consider a simple green salad dressed with a bright vinaigrette to complement its richness. If you’re feeling adventurous, feel free to experiment with variations! Adding a finely diced onion or shallot sautéed before layering can introduce another layer of flavor. A pinch of nutmeg or a sprinkle of fresh thyme or parsley before baking can also enhance its aromatic profile. Don’t shy away from using different cheeses if you don’t have Parmesan on hand – Gruyère or even a sharp cheddar could offer a delightful twist.
Frequently Asked Questions:
Can I make this Julia Child’s Zucchini and Rice Gratin ahead of time?
Yes, you can assemble the gratin a day in advance. Cover it tightly and refrigerate. You may need to add a few extra minutes to the baking time when reheating.
What kind of rice is best for this gratin?
While Arborio or Carnaroli rice are excellent choices for their creamy texture, a good quality long-grain white rice will also work well. Just ensure it’s cooked al dente before mixing with the other ingredients to prevent it from becoming mushy in the oven.
