Zucchini and Rice Gratin Ingredients
For the Gratin

• Olive Oil – For sautéing and flavor; feel free to use avocado oil or melted butter if preferred.
• Garlic – Enhances aroma and flavor; garlic powder can be used as a quick alternative.
• All-Purpose Flour – Helps thicken the mixture; cornstarch can replace it for a gluten-free option.
• Milk – Adds creaminess; almond milk or any dairy-free milk will work for a lighter dish.

Step‑by‑Step Instructions for Zucchini and Rice Gratin
Step 1: Prepare Your Oven and Dish
Preheat your oven to 325°F (163°C) while you grease a 2-quart baking dish with a light coating of olive oil or butter. This will ensure that the Zucchini and Rice Gratin does not stick to the dish, allowing for easy serving later. Set the prepared dish aside as you move on to the next steps.
Step 2: Grate the Zucchini
Wash two medium zucchinis and grate them using a box grater or food processor. Transfer the grated zucchini into a large mixing bowl, letting it sit for a few minutes to allow excess moisture to drain. This step is vital to prevent the gratin from becoming too watery during baking, ensuring a perfect texture.
Step 3: Sauté the Onions
In a skillet, heat 3 tablespoons of olive oil over medium heat. Once hot, add chopped onions and cook them for about 8-10 minutes until they become soft and translucent, stirring occasionally. This step lays the foundation of flavor for your Zucchini and Rice Gratin. Keep an eye on them to avoid browning.
Step 4: Add Garlic and Rice
Add minced garlic to the skillet with the softened onions and cook for an additional minute, stirring to combine the flavors. Next, stir in the rinsed rice and sauté for 2 minutes, allowing it to absorb the fragrant oils. Season the mixture with kosher salt and black pepper to enhance the flavors, creating a hearty base for your gratin.
Step 5: Combine Ingredients
In the mixing bowl with the grated zucchini, add the rice mixture and pour in ½ cup of milk. Mix everything together until well combined. Fold in most of the grated Parmesan cheese, leaving 2 tablespoons aside for later. This blend will form the filling of your Zucchini and Rice Gratin, bursting with flavor.
Step 6: Transfer to Baking Dish
Carefully transfer the zucchini-rice mixture into the greased baking dish, spreading it evenly. Cover the dish tightly with aluminum foil to retain moisture during baking. Place it in the preheated oven and bake for 50 minutes, or until the rice is tender and the zucchini is cooked, creating a comforting, aromatic dish.
Step 7: Finishing Touches
After 50 minutes, remove the foil from the baking dish and drizzle the top with the remaining olive oil. Sprinkle the reserved Parmesan cheese over the gratin to create a deliciously crispy topping. Return the dish to the oven for an additional 10-15 minutes, or until the top is golden brown. Broil for 1-2 minutes if you desire extra crispiness, keeping a close eye to prevent burning.

How to Store and Freeze Zucchini and Rice Gratin
Fridge: Store leftovers in an airtight container for up to 3 days. Make sure to let the gratin cool completely before sealing to preserve its texture and flavor.
Freezer: For longer storage, freeze the Zucchini and Rice Gratin in a freezer-safe container for up to 2 months. Portion it out for easy reheating!
Reheating: When ready to enjoy, thaw overnight in the fridge and reheat in a preheated oven at 350°F (175°C) for about 20-25 minutes, or until warmed through. You can cover it with foil initially to prevent browning before removing it for the last few minutes to crisp up.
Make-Ahead: This dish can be assembled in advance and stored in the fridge (covered) for up to 24 hours before baking. Just remember to adjust the baking time accordingly if it’s going in the oven straight from refrigeration!
Make Ahead Options
These Zucchini and Rice Gratin are perfect for busy meal prep enthusiasts! You can grate and combine the zucchini, rice, and other ingredients up to 24 hours in advance—just store the mixture in an airtight container in the refrigerator to keep it fresh.

When you’re ready to bake, simply transfer the mixture to your greased baking dish, cover with foil, and bake as directed for 50 minutes. For the best results, finish with the drizzled olive oil and reserved cheese just before the final bake. By prepping ahead, you’ll enjoy delicious, home-cooked comfort food with minimal effort on busy weeknights!
Expert Tips for Zucchini and Rice Gratin

• Season Generously: Taste and adjust the seasoning in the rice mixture before baking; this can significantly enhance the flavor of your Zucchini and Rice Gratin.
• Cover Tightly: Ensure the baking dish is tightly covered with foil initially; this retains moisture for perfectly cooked rice and zucchini.

Zucchini and Rice Gratin Recipe FAQs
How do I select the best zucchini?
Absolutely! Look for zucchinis that are firm, with a vibrant green color and shiny skin. Avoid any that have dark spots or look wrinkled, as these are signs of age. Smaller zucchinis are often sweeter and more tender, making them an excellent choice for this recipe.
What is the best way to store leftovers of this gratin?
You can store leftovers in an airtight container in the fridge for up to 3 days. Make sure to let the gratin cool completely before sealing it. If you want to enjoy it beyond that time, consider freezing it for longer-lasting enjoyment!
Can I freeze Zucchini and Rice Gratin? If so, how?
Yes, you can freeze it! Let the gratin cool completely, then portion it into freezer-safe containers. It freezes well for up to 2 months. When you’re ready to eat it, just thaw it overnight in the fridge and reheat in a preheated oven at 350°F (175°C) for about 20-25 minutes, ensuring it’s warmed through. If you cover it initially, it’ll prevent browning during reheating!
What should I do if my gratin comes out too watery?
If that happens, don’t worry—there’s a simple fix! Next time, be sure to drain the grated zucchini well before adding it to the mixture, as this will prevent excess moisture from being released during baking. Also, consider using less milk or adding a bit more flour or rice to absorb any liquid.
Is this recipe suitable for those with dairy allergies?
