It’s the kind of dish that transports you to a sun-drenched kitchen, with the aroma of herbs and garlic filling the air. Let’s get started on creating this delightful classic.
Ingredients:
Preparing the Vegetables and Rice
The first step in creating this beautiful gratin is to prepare our core ingredients. Begin extract by washing your zucchini thoroughly. For this recipe, we want the zucchini to be tender but still hold their shape, so slicing them into relatively thin rounds, about 1/4 inch thick, is ideal. You can do this by hand or with a mandoline for uniformity. If your zucchini are particularly large and seedy, you might consider scooping out some of the seeds, though for younger, smaller zucchini, this isn’t usually necessary.
Next, let’s address the rice. We’re using uncooked white rice, and the key here is to par-cook it. This ensures that the rice will be perfectly tender by the time the gratin is finished baking, without becoming mushy or overcooked. In a small saucepan, combine the 1/2 cup of uncooked white rice with 1 cup of water and a pinch of salt. Bring this to a boil, then reduce the heat to low, cover, and simmer for about 10-12 minutes, or until the rice is just tender but still has a slight bite. You don’t want it fully cooked at this stage; it will finish cooking in the oven. Once par-cooked, drain any excess water and set the rice aside.
Building the Flavor Base
Now, let’s create the aromatic foundation for our gratin. In a large skillet, heat 3 tablespoons of the olive oil over medium heat. Add your minced onions and sauté them gently until they become translucent and softened, which should take about 5-7 minutes. We’re not looking for caramelization here, just a gentle softening to release their sweetness. Next, add the minced garlic to the skillet and cook for another minute until fragrant. Be careful not to burn the garlic, as this can impart a bitter flavor.
Once the onions and garlic are fragrant, we’ll make a simple bécbeef hamel-like sauce to bind everything together. Sprinkle the all-purpose flour over the softened onions and garlic. Stir continuously for about 1-2 minutes, allowing the flour to cook and coat the vegetables. This step, known as making a roux, is crucial for thickening the sauce and preventing a raw flour taste. Gradually whisk in the milk, a little at a time, ensuring that each addition is incorporated smoothly before adding more. Continue to cook, whisking constantly, until the sauce thickens to a consistency that coats the back of a spoon. This should take another few minutes. Season this base generously with kosher salt and freshly ground black pepper to your taste. Remove the skillet from the heat.
Assembling and Baking the Gratin
With all our components ready, it’s time to bring this beautiful gratin together. Preheat your oven to 375°F (190°C). Lightly grease a gratin dish or a shallow baking dish with the remaining 2 tablespoons of olive oil.
In a large bowl, gently combine the sliced zucchini, the par-cooked rice, and the onion and garlic mixture you just prepared. Add half of the grated Parmesan cheese (about 1/3 cup) to the bowl. Toss everything together gently to ensure the zucchini, rice, and sauce are well-distributed and coated. Season again with salt and pepper if you feel it needs it; it’s always good to taste and adjust.
Pour the mixture into your prepared gratin dish, spreading it out evenly. Ensure the zucchini slices are nestled amongst the rice. Finally, sprinkle the remaining Parmesan cheese evenly over the top of the gratin. This will create a lovely, golden-brown, and slightly crispy topping as it bakes.
Place the gratin dish in the preheated oven. Bake for 30 to 40 minutes, or until the zucchini is tender, the rice is fully cooked and creamy, and the top is beautifully golden brown and bubbly. You’ll know it’s ready when the edges are starting to crisp up and the aroma filling your kitchen is irresistible. Let it rest for a few minutes after taking it out of the oven before serving; this allows the flavors to meld and the gratin to set slightly. Enjoy this taste of Julia Child’s culinary wisdom!

Feel free to experiment with other herbs like thyme or savory, or even add a pinch of red pepper flakes for a gentle warmth.
Frequently Asked Questions:
What kind of rice is best for this gratin?
While arborio rice is traditional and lends a lovely creaminess due to its high starch content, other medium-grain or short-grain rice varieties will also work well. The key is a rice that absorbs liquid beautifully without becoming mushy.
Can I make this recipe ahead of time?
Yes, absolutely! You can assemble the gratin a day in advance and store it covered in the refrigerator. Allow it to come to room temperature for about 30 minutes before baking, and you may need to add a few extra minutes to the baking time.
My zucchini seems watery. How can I prevent a soggy gratin?
A common issue with zucchini is its high water content. To combat this, slice your zucchini and lightly salt it. Let it sit in a colander for about 15-20 minutes to draw out excess moisture, then gently pat it dry with paper towels before proceeding with the recipe. This step makes a significant difference in the final texture of your Julia Child Zucchini and Rice Gratin.
