Preparation and Cooking
The beauty of this gratin lies in its layered simplicity. We’ll start by preparing our vegetables, then cook the rice separately, and finally, build our beautiful gratin. Don’t be intimidated by the steps; each one is designed to bring out the best in these ingredients.
First, let’s prepare the zucchini. You’ll want to wash them thoroughly. For this recipe, I like to slice them thinly, about 1/8 to 1/4 inch thick. A mandoline can be a great tool for achieving perfectly uniform slices, but a sharp knife works just as well. The goal is even cooking. Once sliced, place the zucchini in a colander set over a bowl. Sprinkle them generously with kosher salt. This is a crucial step, as zucchini contains a lot of water. The salt will draw out this excess moisture, preventing your gratin from becoming watery and ensuring it bakes up beautifully. Let them sit and sweat for at least 30 minutes, or even up to an hour. You’ll see a good amount of liquid accumulate in the bowl. After they’ve had their salty soak, gently pat the zucchini slices dry with paper towels. This removes any residual salt and any remaining surface moisture.
While the zucchini is salting, we can get a head start on the other components. In a medium saucepan, cook the white rice according to package directions. I typically use a standard long-grain white rice for this. You want the rice to be cooked but still have a slight al dente bite, as it will continue to cook in the oven. Once cooked, set it aside.
Now, let’s build the flavor base. In a large skillet or sauté pan, heat 3 tablespoons of the olive oil over medium heat. Add the minced onions and cook, stirring occasionally, until they are softened and translucent, about 5-7 minutes. You don’t want them to brown too much, just to become sweet and yielding. Stir in the minced garlic and cook for another minute until fragrant. Be careful not to burn the garlic; it can turn bitter quickly.
Next, we create the creamy binder for our gratin. Sprinkle the all-purpose flour over the softened onions and garlic. Stir it in well and cook for about 1-2 minutes, stirring constantly. This is your “roux,” and it helps to thicken the sauce. Gradually whisk in the milk, a little at a time, ensuring each addition is incorporated before adding more. Keep whisking until you have a smooth, slightly thickened sauce. Bring it to a gentle simmer, and let it cook for a minute or two, until it coats the back of a spoon. Season this sauce generously with kosher salt and freshly ground black pepper. Remember, we salted the zucchini, so don’t go overboard with the salt here just yet; you can always adjust at the end. Stir in half of the grated Parmesan cheese until it’s melted and beautifully incorporated into the sauce. Remove the skillet from the heat.
Now it’s time to assemble our gratin. Preheat your oven to 375°F (190°C). Lightly grease a gratin dish or an oven-safe baking dish. You can use the remaining 2 tablespoons of olive oil to coat the dish.
Here’s where the artistry comes in. You can layer the ingredients in a few ways. A classic approach, and one that Julia would likely approve of, is to arrange the zucchini slices in overlapping layers, seasoning each layer lightly with salt and pepper. Then, scatter half of the cooked rice over the zucchini. Spoon about half of the creamy onion-garlic sauce over the rice and zucchini. Repeat with another layer of zucchini, followed by the remaining rice, and then the rest of the sauce.
Finally, sprinkle the remaining 1/3 cup of Parmesan cheese evenly over the top of the gratin. This will create a lovely golden-brown, crispy crust as it bakes.
Place the gratin dish on a baking sheet to catch any potential drips and bake in the preheated oven for 35 to 45 minutes, or until the gratin is bubbly around the edges and the top is golden brown and enticing. You can test for doneness by gently inserting a knife into the center; the zucchini should be tender. If the top is browning too quickly, you can loosely tent it with foil.
Let the gratin rest for about 5-10 minutes before serving. This allows the flavors to meld and the gratin to set up slightly, making it easier to serve. This Zucchini and Rice Gratin is a delightful side dish for grilled meats or fish, or it can stand alone as a light and satisfying vegetarian main course. Enjoy the taste of Julia Child’s timeless cooking!

Frequently Asked Questions:
Can I make this gratin ahead of time?
Absolutely! You can assemble the gratin up to a day in advance. Cover it tightly and refrigerate. When you’re ready to bake, let it 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.
What other vegetables can I add to this tian?
While zucchini is traditional, you can absolutely get creative! Thinly sliced yellow squash, eggplant, or even thinly sliced bell peppers would be wonderful additions. Just ensure they are sliced uniformly for even cooking.
How can I make this recipe dairy-free?
To make this dairy-free, you can substitute the heavy cream with full-fat coconut milk or a plant-based cream alternative. For the cheese topping, nutritional yeast can provide a cheesy flavor, or you can use your favorite dairy-free shredded cheese.
