Step‑by‑Step Instructions for Zucchini Rice Stuffing Casserole
Step 1: Preheat and Prepare Baking Dish
Begin by preheating your oven to 175°C (350°F). While the oven warms up, grab a 23×33 cm baking dish and lightly grease it with cooking spray or a bit of butter to ensure an easy release once baked. This initial preparation sets the stage for your creamy Zucchini Rice Stuffing Casserole.
Step 2: Sauté Vegetables
In a large skillet over medium heat, add a drizzle of oil or a pat of butter to the pan. Once heated, toss in diced zucchini, chopped onion, and shredded carrots. Sauté the vegetables for about 5–7 minutes until they are slightly tender and fragrant, stirring occasionally. Afterward, remove the skillet from heat to prevent overcooking.
Step 3: Mix Casserole Ingredients
In a mixing bowl, combine the sautéed vegetables with the cooked white rice, cream of mushroom soup, sour cream, and 1 cup of shredded cheddar cheese. Sprinkle in garlic powder, salt, and pepper to taste. Stir everything together until well combined; the mixture will be creamy and chunky, perfect for your Zucchini Rice Stuffing Casserole.
Step 4: Layer the Filling
Carefully spread the vegetable and rice mixture evenly into the prepared baking dish, ensuring an even layer for even cooking. Once it’s flat, sprinkle the remaining cheddar cheese over the top, allowing the creamy casserole to shine through as it bakes. This step adds to the richness of the Zucchini Rice Stuffing Casserole’s flavor profile.
Step 5: Prepare the Topping
In a clean bowl, combine the seasoned stuffing mix with melted butter, stirring until the mixture is uniformly moistened. This will create a crispy topping that contrasts beautifully with the creamy filling below. Once combined, spread the stuffing mixture evenly over the top of the casserole, ensuring every inch is covered.
Step 6: Bake to Perfection
Place the assembled casserole in the preheated oven and bake uncovered for about 30–35 minutes. You’re looking for a bubbling center and a beautifully golden brown topping on the stuffing mix. The aroma will fill your kitchen with comforting scents, signaling that your Zucchini Rice Stuffing Casserole is nearly ready to be enjoyed.

How to Store and Freeze Zucchini Rice Stuffing Casserole
Fridge: Store the cooled casserole in an airtight container and keep it in the fridge for up to 4 days. Reheat in the oven for crispy topping or microwave for a quick meal.
Freezer: For longer storage, assemble the Zucchini Rice Stuffing Casserole without baking, wrap it tightly in plastic wrap and foil, and freeze for up to 3 months. Thaw overnight in the fridge before baking.
Reheating: When ready to enjoy, preheat your oven to 175°C (350°F) and bake from frozen or after thawing until hot and bubbly, approximately 30–40 minutes, checking for doneness.
Leftovers: If you have any leftovers, make sure they cool completely before refrigerating to maintain quality. They can also be frozen again for later use, though best consumed fresh.
Make Ahead Options
These Zucchini Rice Stuffing Casserole preparations are perfect for busy weeknights! You can assemble the casserole up to 24 hours in advance and store it covered in the refrigerator.

Zucchini Rice Stuffing Casserole Recipe FAQs
What type of zucchini should I use?
Absolutely! When selecting zucchini for your casserole, look for firm, glossy skin without dark spots or blemishes. Smaller zucchinis tend to be sweeter and more tender. Feel free to substitute yellow summer squash for a vibrant twist; it offers a similar texture and flavor profile.
How long can I store leftovers?
Leftover Zucchini Rice Stuffing Casserole should be stored in an airtight container in the fridge for up to 4 days. When reheating, I recommend using the oven to retain the crispy topping; simply preheat to 175°C (350°F) and warm for about 15-20 minutes until heated through.
Can I freeze the casserole?
Yes! For freezing, assemble the casserole without baking it, cover tightly with plastic wrap followed by aluminum foil, and store in the freezer for up to 3 months. To bake, thaw overnight in the fridge, then bake it in a preheated oven at 175°C (350°F) for 30-35 minutes until hot and bubbly.
What should I do if my casserole is too dry?
If you find that the Zucchini Rice Stuffing Casserole turns out dry, adding a splash of vegetable broth or a bit more sour cream can help moisten everything beautifully. Baking with an extra layer of cheese on top can also provide creaminess and improve texture.
Is the recipe suitable for my gluten-free friend?
If you’re cooking for someone with gluten sensitivities, simply swap out the seasoned stuffing mix for gluten-free breadcrumbs or a gluten-free stuffing blend. Always check labels to ensure your ingredients are free of gluten, making this casserole a delicious option for all your guests!
