Recipe Equipment

You only need a few basic kitchen tools to make this easy zucchini casserole.

9×13-inch baking dish
Large skillet or saucepan
Large mixing bowl
Medium mixing bowl
Wooden spoon or spatula
Chef’s knife
Cutting board
Measuring cups and spoons
Aluminum foil
Cooking spray or butter for greasing

A 9×13-inch casserole dish works particularly well because it gives the zucchini enough room to cook evenly while allowing the stuffing topping to become golden and crisp.

Ingredients

For the Zucchini Casserole

6 cups sliced zucchini — about 3–4 medium zucchini
1 box dry stuffing mix — approximately 6 ounces
1 can cream of chicken soup — 10.5 ounces
½ cup sour cream
½ cup shredded cheddar cheese
½ cup finely diced yellow onion
½ cup melted butter, divided
½ teaspoon garlic powder
½ teaspoon dried parsley
¼ teaspoon black pepper
¼ teaspoon salt, or to taste
¼ cup chicken broth or vegetable broth, if needed

Optional Garnish

2 tablespoons chopped fresh parsley
¼ cup additional shredded cheddar cheese
A light sprinkle of black pepper

The combination of tender zucchini, creamy sauce, melted cheese, and seasoned stuffing creates layers of flavor and texture. The stuffing mix also absorbs some of the flavorful moisture from the casserole while creating a wonderfully crisp top.

Ingredient Notes

Zucchini

Choose medium, firm zucchini with smooth, bright skin. Avoid very large zucchini if possible because they can contain more seeds and excess moisture.

You don’t need to peel zucchini before using it. The skin adds color, texture, and nutrients.

Stuffing Mix

A boxed dry stuffing mix is what gives this casserole its signature savory flavor and crispy topping. You can use your favorite variety, including herb-seasoned stuffing.

For a slightly different flavor, try a cornbread-style stuffing mix.

Cream of Chicken Soup

Cream of chicken soup creates the creamy base that coats the zucchini. If you prefer, you can use cream of mushroom or cream of celery soup instead.

Sour Cream

Sour cream adds richness and a subtle tang that balances the savory stuffing and cheese.

Cheese

Cheddar is an easy choice, but Monterey Jack, Colby, or a cheddar-Monterey Jack blend can also work beautifully.

How to Make Zucchini Casserole with Stuffing Mix

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C).

Lightly grease a 9×13-inch baking dish with cooking spray or a little butter.

Set the prepared dish aside while you prepare the casserole.

Step 2: Prepare the Zucchini

Wash and dry the zucchini thoroughly.

Slice the zucchini into thin, even pieces. Try to keep the slices approximately the same thickness so they cook evenly.

If your zucchini is particularly watery, lightly sprinkle the slices with salt and allow them to sit for about 10 minutes. Pat them dry with paper towels afterward.

This extra step can help reduce excess moisture in the finished casserole.

Step 3: Sauté the Onion and Zucchini

Heat a large skillet over medium heat.

Add approximately 2 tablespoons of melted butter, followed by the diced onion.

Cook for about 2–3 minutes until the onion begins to soften and smell fragrant.

Add the sliced zucchini and cook for another 5–7 minutes.

The zucchini should become slightly tender but should not be completely soft. It will continue cooking in the oven.

Remove the skillet from the heat.

Step 4: Prepare the Creamy Sauce

In a large mixing bowl, combine the cream of chicken soup and sour cream.

Add garlic powder, dried parsley, black pepper, and salt.

Stir everything together until smooth and creamy.

The mixture should have a thick but spoonable consistency.

Step 5: Add the Stuffing Mix

Place about half of the dry stuffing mix into the creamy mixture.

Add the cooked zucchini and onion, then gently fold everything together.

Be careful not to mash the zucchini. You want the slices to remain recognizable and tender.

If the mixture seems extremely thick, add a small amount of chicken or vegetable broth.

Step 6: Add the Cheese

Fold in the shredded cheddar cheese.

As the casserole bakes, the cheese will melt into the creamy sauce, creating delicious golden pockets throughout the dish.

Taste the mixture and adjust the seasoning if needed.

Step 7: Assemble the Casserole

Transfer the zucchini mixture into your prepared baking dish.

Spread it into an even layer using a spatula.

Sprinkle the remaining stuffing mix evenly over the top.

Drizzle the remaining melted butter over the stuffing.

This butter helps the topping become beautifully golden and crispy as it bakes.

Step 8: Bake Until Golden and Bubbly

Cover the baking dish loosely with aluminum foil and bake for approximately 20 minutes.

Then remove the foil and continue baking for another 15–20 minutes.

The casserole should be hot and bubbling around the edges, while the stuffing topping should look golden brown and crisp.

For an extra-crispy top, you can place the casserole under the broiler for 1–2 minutes at the end. Watch it carefully because the stuffing can brown quickly.

Step 9: Rest Before Serving

Remove the casserole from the oven and let it rest for approximately 5–10 minutes.

This short resting period allows the creamy filling to settle slightly, making it easier to serve.

Garnish with fresh parsley if desired.

Then scoop out a generous serving and enjoy it while warm!

Why You’ll Love This Zucchini Casserole

There are plenty of reasons to keep this recipe in your regular dinner rotation.

It’s easy: The ingredients require minimal preparation.

It’s comforting: Creamy sauce, tender zucchini, cheese, and stuffing make every bite satisfying.

Pro Tips & Variations

For the best texture, don’t overcook the zucchini before putting it in the oven. It should be slightly tender but still have some structure.

If your zucchini releases a lot of water, pat it dry before combining it with the sauce.

For extra cheesiness, add another ½ cup of shredded cheddar before adding the stuffing topping.

You can also mix in cooked shredded chicken to turn this side dish into a more substantial meal. For additional flavor, add mushrooms, diced bell peppers, Italian seasoning, or a pinch of red pepper flakes.

For a richer holiday version, replace some of the sour cream with softened cream cheese.

Serving Suggestions

This casserole works especially well as a side dish with roasted or grilled meats.

Serve it alongside:

Roasted chicken
Turkey
Baked ham
Roast beef
Grilled pork chops
Meatloaf
Rotisserie chicken

For a lighter meal, serve a smaller portion with a fresh green salad and grilled chicken.

It also makes an excellent addition to a holiday buffet because the creamy zucchini pairs beautifully with traditional roasted meats and other savory sides.

Storage Information

Allow leftover casserole to cool before transferring it to an airtight container.

Refrigerator

Store leftovers in the refrigerator for 3–4 days.

For the best texture, reheat individual portions in the oven or air fryer so the stuffing topping becomes crispy again.

Freezer

You can freeze the casserole, although the creamy sauce and zucchini may become slightly softer after thawing.

For best results, freeze portions in airtight freezer-safe containers for up to 2 months.

Thaw overnight in the refrigerator before reheating.

Make Ahead

You can prepare the zucchini mixture several hours ahead and refrigerate it before baking. Keep the stuffing topping separate until you’re ready to bake.

This helps prevent the stuffing from becoming soggy.
