Ingredients
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

How to Make Creamy Parmesan Zucchini
Step 1: Preheat the Oven
Preheat your oven to 425˚F. This ensures that your zucchini will bake evenly and become perfectly golden brown.
Step 2: Prepare the Baking Dish
Butter a baking dish generously and set it aside. This will help prevent sticking and add flavor.
Step 3: Salt the Zucchini Slices
Cut the zucchini into ¼-inch slices. Sprinkle salt on each slice. Let them rest for about 15 minutes so the salt can draw out moisture.
Step 4: Wipe Off Excess Moisture
After resting, use a paper towel to wipe each zucchini slice clean of excess salt. This step prevents excess water from making your dish soggy.
Step 5: Arrange Zucchini in Baking Dish
Lay the salted zucchini slices flat in the prepared baking dish. Ensure they are evenly spaced out for proper cooking.
Step 6: Mix Cream Sauce Ingredients
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.
Step 7: Sauté Garlic in Butter
Melt butter in a saucepan over medium heat. Stir in minced garlic and cook for about 20 seconds until fragrant but not browned.
Step 8: Combine Cream Mixture with Garlic
Pour the prepared heavy cream mixture into the saucepan with garlic. Whisk continuously until it begins to bubble gently; this keeps it from curdling.
Step 9: Add Cheese to Sauce
Stir in ½ cup of mozzarella cheese into the cream mixture. Cook for an additional 20 seconds or until fully melted.
Step 10: Pour Sauce Over Zucchini
Carefully pour the creamy sauce over the arranged zucchini slices in the baking dish. Shake lightly to distribute evenly among all slices.
Step 11: Add Remaining Cheese
Sprinkle the remaining parmesan and mozzarella cheese on top of the zucchini for an extra cheesy finish.
Step 12: Bake Until Golden Brown
Place the baking dish in your preheated oven and bake for about 18 to 22 minutes or until it’s golden brown on top.
Step 13: Rest Before Serving
After baking, remove from oven and let stand for about 5 to 10 minutes before serving. This allows flavors to meld beautifully!

Common Mistakes to Avoid
When making Creamy Parmesan Zucchini, a few common mistakes can disrupt the dish’s creamy goodness. Here are some tips to keep in mind.
- Over-salting the zucchini: Salting is essential for drawing out moisture, but too much can make the dish overly salty. Use just enough salt and rinse off excess before cooking.
- Not letting zucchini rest: Skipping the resting step after salting means you may end up with watery zucchini. Always allow the slices to sit for 15 minutes to drain excess moisture.
- Forgetting to whisk constantly: When cooking the cream mixture, not whisking can lead to curdling. Keep stirring until it bubbles to ensure a smooth sauce.
- Skipping cheese layering: Not dividing the cheese can result in uneven flavor. Layer half of the cheeses during preparation and sprinkle the rest on top for a cheesy finish.
- Baking at incorrect temperatures: Baking at too low a temperature may not achieve that golden brown top. Ensure your oven is preheated correctly for best results.
- Serving immediately out of the oven: Cutting into your dish too soon can cause it to fall apart. Allow it to rest for 5-10 minutes before serving for better presentation.
