Ingredients
This creamy Parmesan Zucchini is the ultimate vegetarian dinner recipe! Fresh zucchini slices are covered with cream sauce and baked until bubbly and golden.
For the Zucchini
- 2 pounds zucchini (cut into 1/4-inch slices)
- salt for zucchini
For the Cream Sauce
- 2 tablespoons butter (cut into small cubes)
- 3 cloves garlic (finely minced)
- ½ cup heavy cream
- ½ cup sour cream
- 1 teaspoon Italian seasoning
- 1 teaspoon onion powder
- 1 teaspoon salt
- ½ teaspoon fresh ground black pepper
For the Cheese Topping
- 1 cup grated parmesan cheese (divided)
- 1 cup shredded mozzarella cheese (divided)
For Garnish
- 2 tablespoons fresh parsley, finely chopped

How to Make Creamy Parmesan Zucchini
Step 1: Preheat the Oven
Preheat your oven to 425˚F. This ensures that your creamy zucchini cooks evenly from the start.
Step 2: Prepare the Baking Dish
Butter a baking dish thoroughly to prevent sticking. Set it aside while you prepare the zucchini.
Step 3: Salt the Zucchini Slices
Cut the zucchini into ¼-inch slices. Sprinkle salt generously over each slice. Allow them to rest for about 15 minutes; this step draws out excess moisture.
Step 4: Wipe Excess Salt
After 15 minutes, use paper towels to wipe each slice clean of salt. This ensures your dish doesn’t become overly salty.
Step 5: Arrange Zucchini in Dish
Arrange the salted zucchini slices neatly in your prepared baking dish. Set aside for now.
Step 6: Make the Cream Sauce Mixture
In a mixing bowl, whisk together heavy cream, sour cream, Italian seasoning, onion powder, salt, pepper, and ½ cup of parmesan cheese until well combined. Set aside.
Step 7: Sauté Garlic in Butter
Melt butter in a saucepan over medium heat. Add minced garlic and sauté for about 20 seconds until fragrant but not browned.
Step 8: Combine Cream Mixture with Garlic
Pour in the heavy cream mixture into the saucepan with garlic. Whisk constantly until it starts bubbling lightly. Be careful not to let it curdle!
Step 9: Add Mozzarella Cheese
Stir in ½ cup of shredded mozzarella cheese into the bubbling cream mixture. Cook for an additional 20 seconds or until melted completely.
Step 10: Pour Over Zucchini
Pour the creamy mixture over the arranged zucchini slices in the baking dish. Gently shake to ensure that all slices are coated well.
Step 11: Add Remaining Cheese
Sprinkle the remaining parmesan and mozzarella cheese evenly over the top of your creamy zucchini casserole.
Step 12: Bake
Place in preheated oven and bake for about 18 to 22 minutes or until golden brown on top and bubbly around the edges.
Step 13: Cool Before Serving
Once baked, remove from oven and let cool for about 5 to 10 minutes before serving. This allows flavors to meld beautifully!

Getting your Creamy Parmesan Zucchini just right takes some tips and tricks. Follow these suggestions for a perfect dish every time.
- Use Fresh Zucchini – Fresh, firm zucchini will hold up better during baking and provide a more vibrant flavor.
- Adjust Seasoning – Tailor the seasoning according to your taste; you can add more Italian herbs for an extra punch.
- Monitor Baking Time – Keep an eye on the baking process; ovens vary, so check for that golden-brown top.
- Experiment with Cheeses – While Parmesan and mozzarella are classic choices, try adding Gouda or cheddar for different flavor profiles.

Common Mistakes to Avoid
When making Creamy Parmesan Zucchini, avoiding common pitfalls can make a big difference in your dish’s success. Here are some mistakes to watch out for:
Ignoring the salt step: Not salting the zucchini can lead to excess moisture. Always sprinkle salt and let the slices rest to draw out water.
Skipping the paper towel: Failing to wipe off the excess salt means soggy zucchini. Make sure to pat them dry before layering in the baking dish.
Overcooking the garlic: Cooking garlic too long can result in a burnt taste. Sauté it just until fragrant, about 20 seconds.
Not whisking enough: If you don’t whisk the cream mixture well, it can curdle. Keep stirring until it bubbles gently for a smooth sauce.
Crowding the baking dish: Overlapping zucchini slices can prevent even cooking. Arrange them in a single layer for optimal browning and flavor.

Refrigerator Storage
- Duration: Store in an airtight container for up to 3 days.
