Nothing beats the comfort of a zucchini rice casserole bubbling away in the oven on a busy weeknight. This recipe is pure family nostalgia with its creamy rice base, lots of veggies, and a golden stuffing topping that my kids always ask for second helpings of. You can make it ahead or serve it fresh and I always love its crowd-pleasing flavor.
I whipped this up for a neighborhood potluck the first time and watched the pan disappear in minutes. Everybody wanted the recipe and it has since become a regular comfort dish at our house.
Ingredients
- Zucchini: Sliced fresh and full of water, add bulk and mild flavor, choose smaller zucchini for tenderness
- Onion: Chopped, brings savory depth and sweetness, pick yellow or white for the richest taste
- Carrots: Shredded, a touch of color and mild earthiness, choose firm carrots for best texture
- Cooked white rice: Jasmine or long grain for sturdy fluffiness, cook it ahead or use leftovers
- Sour cream: Gives the casserole its creaminess and tang, choose full fat for the richest bite
- Cream of chicken soup: Creates that classic creamy backbone, use low sodium or homemade if preferred
- Stove Top stuffing mix (chicken flavor): The secret to a crispy topping and extra herby flavor, look for a box with plenty of dried herbs
- Butter: Softened, adds flavor and helps crisp the topping, use real butter for best results
- Salt and pepper: Optional finishers, adjust to your liking and taste before baking
Instructions
- Prepare the Oven and Pan
- Set your oven to 350 degrees Fahrenheit or 175 degrees Celsius and grease a 9 by 13 inch baking dish to prevent sticking
- Prep the Vegetables
- Combine the sliced zucchini, chopped onion and shredded carrots in a large bowl and toss or mix by hand to combine
- Mix the Base
- Add cooked rice, sour cream and cream of chicken soup to the vegetables. Mix thoroughly until every bite will have a bit of everything
- Incorporate the Stuffing Mix
- Gently fold in the dry Stove Top stuffing mix. Spread it through the mixture so there are herby crunchy pieces throughout
- Add Butter and Season
- Melt your softened butter until pourable but not hot. Drizzle it evenly over the casserole mixture then stir in. Adjust with salt and pepper if needed but remember the soup and stuffing mix already add flavor
- Bake the Casserole
- Pour everything into your prepared baking dish and smooth the top. Bake uncovered for 30 to 35 minutes until the top is golden brown and the edges are bubbling
- Cool and Serve
- Remove from the oven and let cool for 5 to 10 minutes so the casserole sets slightly before slicing and serving

The stuffing mix is my favorite part since it turns crisp and golden on top. There is always a happy silence at the table while everyone gets that first crunchy forkful. I remember my grandmother always made sure to sneak in extra butter for the topping and it makes the most irresistible crust.
Storage Tips
Let the casserole cool completely then cover tightly and refrigerate for up to three days. You can also portion and freeze individual servings for up to two months which makes it perfect for meal prep or quick lunches. Thaw in the fridge and reheat in the oven so the topping crisps up again.
Ingredient Substitutions
You can swap the cream of chicken soup for cream of mushroom or celery if you want a vegetarian version. Just make sure to check the seasoning since some canned soups are saltier than others. Use Greek yogurt in place of sour cream for extra tang or a lightened up dish.
Serving Suggestions
Serve as a stand alone meal or as a side for roast chicken, pork chops or grilled salmon. I also like to pair it with a simple green salad to keep things light. The casserole can be dressed up with extra fresh herbs like dill or parsley right before serving.
A Bit of History
Casseroles like this became popular in North America in the mid twentieth century thanks to their convenience and use of canned soups and mixes. Generations later their cozy appeal is only stronger. I love how this recipe mixes homey elements from past decades and fresh garden produce.

This casserole is the kind of dish everyone comes back for. It is cozy, satisfying, and always a winner at the table.
