Ingredients:
- 2 to 2 1/2 lbs zucchini
- 1/2 cup uncooked white rice
- 1 cup onions, minced
- 5 tablespoons olive oil, divided
- 2 garlic cloves, minced
- 2 tablespoons all-purpose flour
- 1/2 cup milk, as needed
- 2/3 cup Parmesan cheese, grated and divided
- Kosher salt and freshly ground black pepper, to taste
Cooking Instructions:
Let’s get started on this wonderful gratin! It involves a few stages, but each one is straightforward and leads us closer to that delicious final product.
1.
Preparing the Zucchini:
First, we need to tackle the zucchini. Wash them thoroughly and trim off the ends. Now, for the slicing: Julia’s recipes often emphasize precision, and while we don’t need surgical accuracy here, relatively uniform slices are key for even cooking. Aim for slices about 1/4-inch thick. You can use a sharp knife, but a mandoline slicer (with extreme caution, of course!) will make this process much faster and more consistent. Once sliced, place the zucchini in a colander set over a bowl or the sink. Sprinkle generously with kosher salt. This salting step is crucial; it draws out excess moisture from the zucchini, preventing your gratin from becoming watery. Let them sit for at least 30 minutes, or even up to an hour. You’ll see a good amount of liquid collecting at the bottom – that’s exactly what we want! After the resting period, gently press the zucchini slices to remove any remaining liquid, and then pat them dry with paper towels. This drying step is also very important for that lovely texture.
2.
Cooking the Rice and Sautéing Aromatics:
While the zucchini is doing its thing, let’s get the rice ready. Cook the 1/2 cup of white rice according to package directions until it’s just tender. You don’t want it mushy, as it will continue to cook in the oven. Drain it well and set aside. Next, in a medium skillet, heat 2 tablespoons of the olive oil over medium heat. Add the 1 cup of minced onions and cook them gently until they are softened and translucent, which should take about 5-7 minutes. You’re not looking for browning here, just a lovely sweetness to develop. Add the 2 minced garlic cloves to the skillet and cook for another minute until fragrant, being careful not to burn the garlic. This aromatic base will infuse the entire gratin with incredible flavor. Remove the onions and garlic from the skillet and set them aside.
3.
Creating the Creamy Sauce Base:
Now, let’s make the binder for our gratin. In the same skillet (no need to wash it, those little bits of onion and garlic add flavor!), add the remaining 3 tablespoons of olive oil and heat it over medium heat. Sprinkle in the 2 tablespoons of all-purpose flour and whisk it constantly for about a minute. This is called making a roux, and it’s the foundation of many delicious sauces. The flour will cook slightly, losing its raw taste. Gradually whisk in the 1/2 cup of milk, a little at a time, making sure each addition is fully incorporated before adding more. Continue whisking until the sauce begins to thicken and become smooth and creamy. You might need a splash more milk if it becomes too thick; we’re aiming for a consistency that will coat the back of a spoon. Season this sauce generously with kosher salt and freshly ground black pepper. Remember that the Parmesan cheese will also add saltiness, so don’t go overboard just yet.
4.
Assembling the Gratin:
This is where it all comes together! Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Lightly grease a gratin dish or a similar-sized baking dish with butter or olive oil. Spread about half of the cooked rice evenly over the bottom of the prepared dish. Then, arrange about half of the salted and dried zucchini slices in an overlapping layer over the rice. Scatter half of the sautéed onions and garlic over the zucchini. Now, pour about half of the creamy sauce over this layer. Sprinkle about half of the grated Parmesan cheese (we have 2/3 cup total, so this is roughly 1/3 cup) over the top. Repeat these layers: the remaining rice, the remaining zucchini, the remaining onions and garlic, the remaining sauce, and finally, sprinkle the last of the Parmesan cheese evenly over the top. This layering creates a beautiful visual appeal and ensures flavor in every bite.
5.
Baking to Golden Perfection:
Cover the gratin dish tightly with aluminum foil. Place it on a baking sheet (to catch any potential drips) and bake in the preheated oven for 30 minutes. After 30 minutes, remove the aluminum foil. Continue baking for another 20-25 minutes, or until the gratin is golden brown on top, bubbly around the edges, and the zucchini is tender. You can test for tenderness by gently piercing a piece of zucchini with a fork; it should yield easily. If the top is browning too quickly, you can loosely tent it with foil. Once it’s beautifully golden and tender, remove it from the oven and let it rest for about 10-15 minutes before serving. This resting period allows the flavors to meld and the gratin to set up slightly, making it easier to serve. The result is a wonderfully comforting and flavorful dish that showcases the simple beauty of zucchini. Enjoy!

Frequently Asked Questions:
Can I make this Julia Child’s Zucchini and Rice Gratin ahead of time?
Absolutely! This gratin is an excellent candidate for make-ahead preparation. You can assemble it completely, cover it tightly, and refrigerate it for up to 24 hours before baking. You might need to add a few extra minutes to the baking time to ensure it’s heated through.
What kind of cheese is best for this tian?
Julia Child often favored Gruyère for its nutty, slightly sweet flavor, and it works beautifully here. However, a good quality Swiss cheese or even a sharp cheddar can be delicious substitutes. The key is to use a cheese that melts well and has a robust flavor to complement the zucchini and rice.
My zucchini releases a lot of water. How can I prevent a watery gratin?
A common concern with zucchini! Before adding your sliced zucchini to the gratin, lightly salt the slices and let them sit in a colander for about 30 minutes. This process draws out excess moisture. After the time is up, gently pat the zucchini dry with paper towels before layering them into your dish. This simple step makes a significant difference in the final texture.
