Our favorite stuffing zucchini casserole will be your favorite, too! This simple vegetable casserole is loaded with flavorful ingredients yet easy enough to cook for weeknights or an easy holiday side dish.
We are a zucchini-loving family and we are always looking for ways to use it up! You would not believe how many we always end up with from our garden!
This recipe is an oldie but a goodie and is our favorite zucchini casserole, literally! If you love stuffing, cheese, zucchini, carrots, and onions then you will love this recipe too!
This was inspired by my Mom's best zucchini casserole. I don't think I'll ever make anything that good, but I wanted to give it a shot with this zucchini recipe!
It goes great with lots of different main dishes but we love it with this raspberry chicken and boursin chicken.
Why You Will Love Zucchini Casserole with Stuffing
- It's incredibly easy to prepare and requires minimal ingredients.
- A nice combination of textures with its crunchy stuffing mix and vegetables.
- Everyone will love this dish, both kids and adults alike.
- It is an excellent side dish that goes well with any main course you serve.
Ingredients
You'll only need a few simple ingredients to make this zucchini casserole with Stove Top stuffing recipe. Everything you need is either in your kitchen or a short trip to the grocery store away.
Be sure to check the recipe card at the end of the post for exact amounts.
- Veggies: This stuffing casserole is made with zucchini, carrots, and onion.
- Stuffing mix: This works with any type of boxed stuffing mix but in our house we really enjoy the classic Stove Top stuffing mix. Choose your favorite brand and flavor stuffing to make this recipe.
- Cream of mushroom condensed soup: I find this works great with the flavors in this dish but you can also use cream of chicken or cream of celery soup.
- Butter and sour cream: For more rich flavors and creaminess.
- Cheese: Because cheese makes everything taste better! We especially enjoy cheddar but you can use your favorite including mozzarella, parmesan, gouda, provolone, Swiss cheese, Havarti, gruyere cheese, and jack cheeses.
- Crispy fried onions: An optional topping but it adds a punch of flavor and extra crispiness to your zucchini stuffing casserole.
Substitutions and Variations
- Zucchini: Yellow squash or spaghetti squash works fine instead or you can use a combination of squashes.
- Add More Vegetables: Consider mixing in some peas, corn kernels, bell peppers, chopped broccoli florets, baby spinach or kale leaves, mushrooms, or cauliflower.
- Add Protein: Turn this into a main dish casserole by adding cooked or leftover cubed chicken or turkey, cooked Italian sausages or sausage crumbles, cooked bacon, your favorite cooked ground meat.
- Sour cream: You can use Greek yogurt instead of sour cream but it does change the flavor slightly.
- Add Flavor: Add more herbs and spices such as garlic powder, onion powder, paprika, oregano, basil, or thyme when cooking your vegetables, or sprinkle some freshly chopped parsley on top right before serving.
- Add a Grain: Add some cooked white or brown rice, lentils, or quinoa to the casserole with the vegetable mixture.
- Stuffing Lover: I love stuffing so much I will use a second box to place a layer on top. The decision is up to you. Either way it works out beautifully!

How to Make Our Favorite Zucchini Casserole
This zucchini casserole is super easy. It only takes a few minutes and a few simple steps. It's a snap!
The highlights are here, but you'll find the complete instructions in the recipe card at the end of the post.
- Boil the zucchini until tender. Once it's cooked drain it and set aside.
- Combine the stuffing, creamed soup, and sour cream.
PRO TIP: Be sure to drain the zucchini very well to prevent the casserole from turning out soggy.
- Cook the carrots and onions in a bit of oil in a skillet until they're tender.
- Add the cooked zucchini, onion and carrots to the stuffing and soup mixture in a large mixing bowl.
- Pour the vegetable mixture into a baking dish.
- Top with the crispy onions if you're using them and finish with a layer of cheese.
PRO TIP: If you have want to add more stuffing mix to the stop. Toss the stuffing mix with melted butter and add it to the top of the veggie stuffing mixture.
- Bake in the oven until the cheese is melted.
⭐️ Hint: Stir the stuffing into the melted butter in your skillet until coated but don't cook the stuffing.
Storage
- Refrigerator: Store for up to 3 days in an air-tight container.
- Freezer: Store in an air-tight, freezer-safe container for up to 3 months.
- Reheat: Place in a skillet with a lid and cook over low heat until heated through.
Tips
- Make sure all the ingredients are evenly distributed throughout the dish by stirring well before transferring it to your baking dish.
- For more flavor, cook the zucchini slices in vegetable broth instead of water.
- For a healthier version of this casserole, you can use low-sodium or reduced-fat condensed cream soups.
- Drizzle some additional melted butter on top prior to baking for an even more tasty and crisp topping.
FAQ
The zucchini slices should be cooked until they are tender, about 5 minutes. Make sure to drain any excess liquid before adding them into the bowl.
If you have a food processor, you can use the grating attachment to quickly shred carrots for this recipe. Alternatively, if you don't have one, using a hand grater would also work just fine.
Of course! To make individual portions you can use ramekins or oven-safe mugs to scoop out your mixture into each container then top with stuffing mix and cheese before baking. That way you’ll have delicious individual servings ready in no time! You'll know it's done when the cheese on top is nicely melted and bubbly.

Great recipe, thank you. Can you prep this the night before, refrigerate it, and cook it the following day, or would it be better to fully cook it the day before you plan to serve it and reheat it the next day?
Karin and Ken
Glad you like this recipe! As always you are most welcome. I would cook everything the day before except without the topping. If you use extra stuffing, crispy fried onions and/or cheese I would add that when reheating, before serving. When I take or send this casserole somewhere I always will send or bring a bag of shredded cheese with it or with me and I put it on top while casserole is reheating. I have prepared the casserole uncooked in my fridge for the next day and found it became too "wet" from sitting uncooked overnight. That is why I always cook everything but the cheese first. Hope I have answered your question. If any more come up please don't hesitate to ask. Take care and all the best. Karin
Angie

You are most welcome! You made my day! I love hearing when someone loves one of my recipes! Extra onions and cheese on top will taste even better! Well I think so even though my husband would disagree! I am definitely the cheese lover in the family! Take care and all the best. Karin
Anne
I used an extra box of stuffing for the top and some extra butter and this tasted DELICIOUS! It is now going to be made regularly I can’t wait to try it with the fried onions Sounds good too
Karin and Ken
Happy to hear you enjoyed this casserole! Glad you tried it with the extra stuffing on top! I can’t wait to hear whether you think the stuffing on top or crispy fried onions are better! If you have a moment please let me know! I would love to hear! Take care and all the best. Karin

Susan
We LOVED this casserole. I made it with a half a box of stuffing on top and it was so good. Next time I’m trying it with the onions on top. Thank you so much for sharing it
Karin and Ken
Glad to hear you enjoyed it! Please let me know if you don’t mind which version you prefer. I think both toppings are great and am curious to hear your opinion! If you don’t mind! Take care and enjoy the rest of your day! Karin
Lisa
This was really delicious! I used just one box of stuffing, it was perfect.
Karin and Ken
So happy to hear you enjoyed it! You truly made my day. I can’t thank you enough for taking the time to let me know. Hopefully you find some other recipes on our site that you enjoy just as much! Take care and all the best to you. Karin
Holly
1 box of stuffing or 2?
Karin and Ken
I can’t apologize enough for the delay in my response. Just to clarify you need one box of stuffing (1 1/4 cup) to mix with the soup and sour cream. You have two options for the topping. I love stuffing and would always prefer to use a second box (1 1/4 cup) for the topping (and butter), before the cheese. My husband prefers to put French’s Fried Onions on top and then the cheese which is why you would only need one box. I was just trying to give everyone options when making what we think is a delicious casserole! I will clarify this in the instructions once I return home. We left so quickly I didn’t even bring my laptop or I would make changes now. Please let me know what you think of this dish if you try it. I would love to hear! All the best to you. Karin
Hattie
