Ingredients You’ll Need
This Cheesy Zucchini Casserole Recipe calls for simple, everyday ingredients that work beautifully together to create layers of flavor and texture. Each element adds something special, from the tender zucchini to the crispy breadcrumb topping and the rich cheeses that hold it all together perfectly.
- 4 medium zucchinis, sliced: The star of the dish, providing freshness and a tender bite.
- 1 teaspoon salt: Helps draw out moisture from zucchinis for a better texture.

- 1 onion, finely chopped: Adds sweetness and depth when sautéed.
- 2 cloves garlic, minced: Brings aromatic warmth to every spoonful.
- 1 cup breadcrumbs: Gives a delightful crunch and binds the casserole.
- 1/2 teaspoon black pepper: A little spice to enhance all the other flavors.
- 1/4 teaspoon dried thyme: For a gentle herbal note.
- 1/4 teaspoon dried oregano: Adds a Mediterranean touch.
- 1/2 cup grated Parmesan cheese: Offers a nutty, salty kick.
- 1 1/2 cups shredded mozzarella cheese: Melts beautifully, creating that signature cheesy stretch.
- 1/2 cup heavy cream: Makes the casserole luxuriously creamy.
- 2 large eggs, beaten: Helps hold everything together perfectly.
- 1 tablespoon chopped fresh basil, for garnish: Adds a pop of color and freshness just before serving.
How to Make Cheesy Zucchini Casserole Recipe
Step 1: Preheat and Prepare the Zucchini
Start by heating your oven up to 375°F (190°C). While that warms, spread the zucchini slices across a baking sheet and sprinkle them generously with salt. This step is crucial because it draws out excess moisture from the zucchini, which keeps your casserole from becoming watery. After 15 minutes, gently pat them dry with paper towels to remove that released moisture.
Step 2: Sauté Onion and Garlic
Next, heat the olive oil in a skillet over medium heat and toss in the chopped onion and garlic. Cook until the onion turns translucent and soft, about five minutes. This soft sauté releases their natural sweetness and deepens the flavor base for your cheesy zucchini masterpiece.
Step 3: Mix the Ingredients
In a large mixing bowl, combine the sautéed onion and garlic with the dried zucchini slices, breadcrumbs, black pepper, thyme, oregano, Parmesan cheese, one cup of mozzarella, heavy cream, and beaten eggs. Stir everything together until you have a well-incorporated, creamy mixture that promises rich flavor in every mouthful.
Step 4: Assemble and Bake
Pour this mixture into a greased 9×13-inch baking dish, spreading it out evenly. Sprinkle the remaining half cup of shredded mozzarella over the top — this final layer melts and browns into a golden, bubbly crown. Bake the casserole for 25 to 30 minutes until the top is golden brown and the edges are bubbling, signaling perfection.
Step 5: Cool and Garnish
Once out of the oven, let the casserole rest for a few minutes to set up nicely. Then, sprinkle chopped fresh basil on top for a fragrant, colorful finish that elevates your Cheesy Zucchini Casserole Recipe to restaurant-worthy status.

Make Ahead and Storage
Storing Leftovers
After enjoying your casserole, let leftovers cool completely before storing them in an airtight container in the refrigerator. They’ll keep well for up to three days, making for easy, tasty meals the next day.
Freezing
This Cheesy Zucchini Casserole Recipe freezes beautifully! Place cooled portions into freezer-safe containers or bags, and freeze for up to two months. Be sure to thaw overnight in the fridge before reheating to keep the texture just right.
Reheating
To reheat, pop your casserole pieces into the oven at 350°F (175°C) covered with foil to maintain moisture, heating until warmed through and bubbly again. Alternatively, microwave leftovers on medium power in short bursts, stirring gently to avoid drying.
FAQs
Can I use zucchini noodles instead of sliced zucchini?
Zucchini noodles are much thinner and carry more moisture, which may make the casserole soggy. For best results, stick with sliced zucchini and be sure to salt and dry well as the recipe suggests.
Is it possible to make this casserole vegetarian?
Absolutely! This recipe is already vegetarian-friendly since it contains no meat. Just make sure your cheese and cream are from vegetarian sources if that is a concern.
Can I substitute the heavy cream with something lighter?
You can use half-and-half or whole milk as a lighter option, but keep in mind that the casserole may be less rich and creamy. Adding a little extra cheese can compensate for the lighter texture.
How can I make this recipe gluten-free?
Swap out the regular breadcrumbs for gluten-free breadcrumbs, which are widely available. This simple substitution keeps the crunchy texture without compromising flavor.
Can I prepare this casserole ahead of time and bake later?
Yes! Assemble the casserole as directed, cover it tightly with plastic wrap or foil, and refrigerate for up to 24 hours before baking. This makes it a perfect option for meal prep or entertaining.
