Cooking Instructions:
This gratin comes together in a few distinct stages, each contributing to the final delightful outcome. We’ll start by preparing our vegetables, then create a simple creamy base, and finally assemble and bake this wonderful dish.
1. Preparing the Zucchini and Rice:
Begin extract by washing your zucchini thoroughly. Trim off the ends. Julia often liked to slice her vegetables thinly and uniformly for even cooking, so aim for slices about 1/4-inch thick. A mandoline slicer can be incredibly helpful here, but a sharp knife will do the job just fine. The key is consistency. Next, it’s time to address the rice. In a medium saucepan, combine the uncooked white rice with 1 cup of water. 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 it fully cooked, as it will continue to cook in the oven. Once cooked, fluff the rice with a fork and set it aside. This pre-cooking ensures that the rice absorbs the flavors of the gratin without becoming mushy.
2. Sautéing the Aromatics:
In a large skillet over medium heat, warm 3 tablespoons of the olive oil. Add your finely minced onions and cook them, stirring occasionally, until they are softened and translucent, about 5-7 minutes. We’re not looking for browning here, just a gentle softening that releases their sweet flavor. Add the minced garlic to the skillet and cook for another minute until fragrant. Be careful not to burn the garlic, as it can turn bitter. This aromatic base will infuse the entire dish with a wonderful savory depth.
3. Creating the Creamy Sauce:
To the skillet with the softened onions and garlic, sprinkle the all-purpose flour. Stir it in well with the olive oil and vegetables to create a roux. Cook this mixture for about 1-2 minutes, stirring constantly, to cook out the raw flour taste. This step is crucial for achieving a smooth, lump-free sauce. Gradually whisk in the milk, a little at a time, ensuring each addition is fully incorporated before adding more. Continue whisking and cooking over medium-low heat until the sauce thickens to a creamy consistency, coating the back of a spoon. Season generously with kosher salt and freshly ground black pepper. Remember that the Parmesan cheese will also add saltiness, so season mindfully. Stir in 1/3 cup of the grated Parmesan cheese until it melts into the sauce, adding a wonderful nutty flavor.
4. Assembling the Gratin:
Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Lightly grease a baking dish (a 9×13 inch dish or a similar-sized gratin dish works well) with the remaining 2 tablespoons of olive oil. In a large bowl, gently combine the sliced zucchini, the partially cooked rice, and the creamy onion-garlic sauce. You want to coat everything evenly without bruising the zucchini. This ensures that every bite will be flavorful and moist.
5. Baking to Golden Perfection:
Pour the zucchini and rice mixture into the prepared baking dish, spreading it out evenly. Sprinkle the remaining 1/3 cup of grated Parmesan cheese evenly over the top. This is where the magic happens! Place the dish in the preheated oven and bake for 30-40 minutes, or until the gratin is bubbly and the top is golden brown and delicious. You can test for doneness by inserting a knife into the center; it should go through easily, indicating that the zucchini and rice are tender. If the top starts to brown too quickly, you can loosely tent it with aluminum foil. Let the gratin rest for a few minutes after removing it from the oven before serving. This allows the flavors to meld and the dish to set slightly, making it easier to serve. Enjoy this delightful taste of Julia’s kitchen!

Frequently Asked Questions:
Can I make this gratin ahead of time?
Yes, you absolutely can! You can assemble the gratin up to a day in advance. Cover it tightly with plastic wrap and refrigerate. When you’re ready to bake, allow it to sit at room temperature for about 30 minutes before placing it in the oven. You might need to add a few extra minutes to the baking time to ensure it’s heated through.
What kind of rice is best for this recipe?
While Julia Child’s Zucchini and Rice Gratin works well with most long-grain white rice like Basmati or Jasmine, you can also experiment with other varieties. Arborio rice, typically used for risotto, will lend a creamier texture. Just be sure to cook the rice partially before layering it into the gratin to ensure it becomes tender.
