Cooking Instructions
This gratin comes together in a few key stages, each contributing to the final harmonious blend of flavors and textures. We’ll start by preparing our vegetables, then cook the rice, and finally assemble and bake our beautiful gratin.
1.
Preparing the Zucchini and Aromatics
Begin extract by prepping your zucchini. Wash them thoroughly and then slice them thinly, about 1/8-inch thick. A mandoline slicer is your best friend here for achieving uniform slices, which will ensure even cooking. If you don’t have one, a sharp knife and a steady hand will do the trick. Don’t worry about peeling the zucchini; the skin adds a lovely bit of color and texture. Next, let’s tend to the flavor base. In a large skillet, heat 3 tablespoons of the olive oil over medium heat. Add the minced onions and cook them gently, stirring occasionally, until they are softened and translucent, about 5-7 minutes. You want them to be tender and sweet, not browned. Add the minced garlic to the skillet and cook for another minute until fragrant, being careful not to burn it.
2.
Cooking the Rice
While your onions and garlic are sautéing, let’s get the rice going. You can cook the rice in the traditional way: rinse the 1/2 cup of white rice under cold water until the water runs clear to remove excess starch. Combine the rinsed rice with 1 cup of water (or according to your rice package directions) in a small saucepan. Bring to a boil, then reduce the heat to low, cover, and simmer for about 15-20 minutes, or until the water is absorbed and the rice is tender. Once cooked, fluff the rice with a fork and set it aside. It’s important for the rice to be cooked but not mushy, as it will continue to cook and absorb moisture in the gratin.
3.
Creating the Sauce and Assembling the Gratin
Now, back to the skillet with the onions and garlic. Sprinkle the 2 tablespoons of all-purpose flour over the softened onions and garlic. Stir well and cook for about 1 minute, allowing the flour to cook slightly. This is your roux, which will help thicken the sauce. Gradually whisk in about 1/4 cup of the milk, stirring constantly to prevent lumps. Continue to add milk a little at a time, whisking until you have a smooth, creamy sauce. You might not need the entire 1/2 cup of milk; the consistency should be similar to heavy cream. Season the sauce with kosher salt and freshly ground black pepper to your liking. Stir in 1/3 cup of the grated Parmesan cheese until it’s melted into the sauce. This adds a wonderful depth of flavor. Now, it’s time to assemble. In a medium bowl, gently toss the sliced zucchini with the remaining 2 tablespoons of olive oil, a pinch of salt, and pepper. In a separate bowl, combine the cooked rice with about half of the creamy sauce.
4.
Layering and Baking
Preheat your oven to 375°F (190°C). Lightly grease a baking dish (an 8×8 inch dish or a similar-sized gratin dish works well). Begin extract by spreading the rice mixture evenly over the bottom of the prepared baking dish. Next, arrange the seasoned zucchini slices in overlapping layers on top of the rice. You can be creative with your arrangement; circular patterns or neat rows both look beautiful. Pour the remaining sauce evenly over the zucchini layers. Make sure to get some of that lovely onion and garlic mixture distributed throughout.
5.
The Final Touch and Baking to Perfection
Finally, sprinkle the remaining 1/3 cup of grated Parmesan cheese evenly over the top of the gratin. This is what will give you that irresistible golden-brown, bubbly crust. Place the baking dish on a baking sheet (to catch any potential drips) and bake in the preheated oven for 30 to 40 minutes. You’re looking for the zucchini to be tender when pierced with a fork and the topping to be golden and bubbling. If the top starts to brown too quickly, you can loosely tent it with foil. Once baked to perfection, 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 serve. Enjoy this delightful taste of Julia Child’s culinary wisdom!

FAQs:
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 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 then bake as directed, adding a few extra minutes to the cooking time if needed.
What kind of rice is best for this tian?
While many types of rice will work, a medium-grain rice like Arborio or a long-grain white rice such as Basmati or Jasmine are excellent choices. They absorb the liquids beautifully and create a lovely, creamy texture when baked.
