Cooking Instructions:
Preparing the Zucchini and Rice
Our first step is to get our key components ready. Begin extract by washing your zucchini thoroughly. You’ll want to slice them very thinly, ideally about 1/8-inch thick. A mandoline slicer is your best friend here for achieving uniform slices, which will ensure even cooking and a beautiful presentation. If you don’t have a mandoline, a very sharp knife and a steady hand will do. Don’t worry about salting the zucchini at this stage; Julia’s recipe is designed to bring out the natural flavors without excessive steps. For the rice, we’ll cook it until it’s just tender, not mushy. In a small 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 al dente. Fluff it with a fork and set aside. Overcooked rice will turn to mush in the gratin, so keep a close eye on it.
Building the Flavor Base
Next, we’ll create the aromatic foundation for our gratin. 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. We’re not looking for browning here, just gentle cooking to release their sweetness. Now, stir in the minced garlic and cook for another minute until fragrant. Be careful not to burn the garlic, as it can turn bitter. Remove the onion and garlic mixture from the skillet and set it aside. In the same skillet, add the remaining 2 tablespoons of olive oil. Add the thinly sliced zucchini in batches, if necessary, to avoid overcrowding the pan. Sauté the zucchini for about 3-4 minutes per batch, just until it begin extracts to soften slightly. You want it to be pliable but still hold its shape. Season lightly with salt and pepper as you go. Remove the sautéed zucchini from the skillet and set it aside with the onion and garlic.
Crafting the Creamy Sauce
This is where our gratin gets its luscious texture. In the same skillet (no need to wash it – those little bits add flavor!), melt 2 tablespoons of butter (if you’re using butter, otherwise use the reserved olive oil if you prefer) over medium heat. Whisk in the 2 tablespoons of all-purpose flour to create a roux. Cook the roux for about 1 minute, stirring constantly, until it smells slightly nutty. This cooks out the raw flour taste. Gradually whisk in the 1/2 cup of milk, a little at a time, ensuring that each addition is fully incorporated before adding more. Continue whisking until the sauce thickens to a smooth, creamy consistency that coats the back of a spoon. This should take a few minutes. Season this sauce generously with kosher salt and freshly ground black pepper. Taste and adjust the seasoning as needed; this is the primary flavor binder for our gratin.
Assembling and Baking the Gratin
Now for the satisfying assembly! Preheat your oven to 375°F (190°C). Lightly grease a medium-sized gratin dish or a similar oven-safe baking dish. In a large bowl, gently combine the par-cooked rice, the sautéed zucchini, and the sautéed onion and garlic mixture. Pour about half of the creamy sauce over this mixture and toss gently to coat everything evenly. You want the ingredients to be nicely moistened but not swimming in sauce. Now, pour about half of the remaining sauce over the mixture in the gratin dish, spreading it out evenly. Sprinkle half of the grated Parmesan cheese (about 1/3 cup) over this layer. Now, carefully arrange the remaining zucchini slices in an attractive, overlapping pattern on top, if you like, or simply spread them evenly. Pour the rest of the creamy sauce over the top, ensuring it seeps down between the layers. Finally, sprinkle the remaining Parmesan cheese evenly over the entire surface of the gratin. This will form a beautiful golden crust as it bakes.
Place the gratin dish on a baking sheet to catch any potential drips. Bake in the preheated oven for 30-35 minutes, or until the gratin is bubbling around the edges and the top is golden brown and slightly crispy. The zucchini should be tender when pierced with a fork. If the top starts to brown too quickly before the gratin is heated through, you can loosely tent it with aluminum foil. Let the gratin rest for about 5-10 minutes before serving. This allows the flavors to meld and the gratin to set slightly, making it easier to portion. Serve hot and enjoy the comforting embrace of this classic French preparation, a true taste of Julia’s culinary wisdom.

Frequently Asked Questions:
Can I make this Julia Child’s Zucchini and Rice Gratin ahead of time?
Yes, absolutely! You can assemble the gratin a day in advance and store it covered in the refrigerator. When you’re ready to bake, you may need to add a few extra minutes to the cooking time to ensure it’s heated through.
What kind of rice is best for this Tian de Courgettes au Riz?
While you can use a medium-grain white rice like Arborio or Carnaroli for a creamy texture, a long-grain white rice such as basmati or jasmine will also work well and provide a lighter feel. Ensure the rice is cooked al dente before incorporating it into the gratin.
