Whether we’re using extra zucchini from the garden or making a nice holiday casserole this vegetable hot dish is very versatile.

Zucchini with Stuffing Casserole Recipe
Perfect for a summer potluck, family reunion or warm vegetable side dish at the holidays this casserole is versatile and easy to make!
Like a zucchini squash sandwiched between layers of chicken flavored dressing this recipe is unique, but still delicious.
We enjoy recipes like this one, our Baked Vegetable Medley and Broccoli and Mushroom Casserole that helps us eat more veggies without getting bored.
We have eaten this alone for a light dinner in the summer heat, but it’s more popular as a side at a bigger meal.
Why This Recipe Works:
- Great way to use lots of zucchini from the garden or a friend
- So much flavor while being a bit unique, but still easy to make
- While it makes a big batch the leftovers reheat well within 1 – 2 days
- Parmesan cheese can be sprinkled on top of the vegetable mixture for even more flavor
- Adds variety to vegetables on the dinner table
Ingredients Needed:
- Zucchini – young, tender zucchini squash that are firm and fresh produce the best results.
- Onion – sweet, white, or yellow onion all work fine. I like to chop coarsely since they get boiled briefly with the zucchini.
- Carrots – cleaned and shredded or pre-cut into matchsticks work great.
- Cream of chicken soup – makes the recipe so creamy! Other cream of celery, cheddar cheese or cream of mushroom soups may be substituted to change the flavor profile.
- Sour cream – another creamy ingredient.
How to Make This Zucchini Casserole
Preheat oven to 350°F Slice up the zucchini and coarsely chop the onions. Grate carrots if necessary.
In a large mixing bowl stir together cream of chicken soup, sour cream and carrots.
Bring pot of water to a boil. Salt water before adding zucchini and onions. Boil for 3 to 4 minutes and drain well.
Pour drained vegetables into bowl with cream mixture and use a wooden spoon to mix.
In a small mixing bowl melt butter and stir in the packet of stuffing mix.
Spread half of stuffing mixture in bottom of a lightly greased 9 x 13″ casserole dish.
Then pour creamy vegetable mixture evenly over the top. Take care not to displace too much of the stuffing mixture.
Sprinkle remaining stuffing mixture evenly over the top. Bake for 25 – 30 minutes until the stuffing is a nice golden brown and the casserole is baked through.
Recipe Tips & Tricks:
- Slicing fresh zucchini thinly allows for maximum creaminess and diversity of flavors in every bite
- Buying shredded carrots saves time and makes this an easy vegetable casserole recipe
- 6 cups of sliced zucchini is about 4 – 5 small zucchini
- We prefer small, tender, young zucchini that have much smaller seeds and thinner rinds
- Vegetables can easily be doubled to make a healthier casserole with a lower cream and stuffing ratio

I’m going to try this as soon as our Zucchini ripens. Havntent ideas for variations, too … especially some ways to lower sodium content, às I hàve some heart health issues.
I love this casserole. I added Italian cheese blend shreds on top. I grew up using this recipe but lost it in a move. Thank you.
I have been making this recipe for years. Has anyone ever tried not blanching the zucchini first? I always double the stove top stuffing mix.
Glad I found this recipe. I have frozen several cups of shredded zucchini. I will be using mushroom soup since the stuffing is already chicken flavored. So glad to be able to shrink recipes to smaller portions. Watching the carbs. Thanks for sharing.
Love it I added celery to the onion and made the stuffing as directed on the box Thank you
How far ahead can this be made before baking it?
Hey There! The creamy base mixture can be made a day ahead of time, but I would wait to sprinkle the stuffing and butter on top until you are ready to bake so that it doesn’t get soggy. Hope you enjoy!
Very good. Just a little too much for two people. Can you freeze it?
Hey There! I haven’t tested, but I do think the crunchy stuffing topping would become a bit soft in the freezing and reheating process. If that doesn’t bother you I think the dish will still have great flavors. Thanks for trying our recipe!
O. K. Maybe not freeze it. How long do you think it will keep refrigerated?
