Ingredients
Ingredients:
– 2 pounds zucchini (cut into 1/4-inch slices)
– salt for zucchini
– 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
– 1 cup grated parmesan cheese (divided)
– 1 cup shredded mozzarella cheese (divided)
How to Make Creamy Parmesan Zucchini
Step 1: Preheat the Oven
Preheat your oven to 425˚F to ensure it’s hot enough to bake the zucchini evenly.
Step 2: Prepare the Baking Dish
Butter a baking dish generously and set it aside for later use.
Step 3: Slice and Salt the Zucchini
Cut the zucchini into ¼-inch slices. Sprinkle salt over each slice and let them rest for about 15 minutes. This step helps draw out moisture from the zucchini.
Step 4: Wipe Off Excess Salt
After resting, use paper towels to gently wipe each slice, removing excess salt.
Step 5: Arrange Zucchini in Baking Dish
Place the sliced zucchini neatly in the prepared baking dish, laying them flat so they cook evenly.
Step 6: Mix Cream Sauce Ingredients
In a mixing bowl, whisk together heavy cream, sour cream, Italian seasoning, onion powder, salt, pepper, and half of the grated parmesan cheese until well combined. Set this mixture aside.
Step 7: Sauté Garlic in Butter
Melt butter in a saucepan over medium heat. Stir in minced garlic and cook briefly until fragrant (about 20 seconds).
Step 8: Combine Cream Mixture with Garlic
Add the heavy cream mixture to the saucepan with garlic. Whisk continuously until it begins to bubble gently; this keeps the cream from curdling.
Step 9: Melt in Mozzarella Cheese
Stir in half of the shredded mozzarella cheese into the bubbling sauce. Continue cooking until all cheese is melted (about another 20 seconds).
Step 10: Pour Sauce Over Zucchini
Carefully pour the creamy sauce over the arranged zucchini slices in the baking dish. Gently shake or tilt the dish to distribute sauce evenly.
Step 11: Top with Remaining Cheese
Sprinkle the remaining parmesan and mozzarella cheeses over everything generously.
Step 12: Bake Until Golden Brown
Bake in your preheated oven for about 18 to 22 minutes or until the top is golden brown and bubbly.
Step 13: Let Stand Before Serving
Once baked, remove from oven. Allow it to stand for about 5 to 10 minutes before serving to cool slightly. Enjoy your delicious creamy Parmesan Zucchini!

Whisk Constantly: When heating the cream mixture, whisk continuously to avoid curdling and achieve a smooth consistency.
-
Bake Until Golden: Keep an eye on the dish while baking; it should be bubbly and golden brown for optimal taste and presentation.

Common Mistakes to Avoid
Making Creamy Parmesan Zucchini can be a delightful experience, but there are common mistakes that can affect the outcome. Here are some pitfalls to watch out for:
-
Over-salting the zucchini: It’s crucial to sprinkle salt on the zucchini slices before cooking, but overdoing it can lead to an overly salty dish. Use just enough salt and be sure to wipe off excess moisture after resting.
-
Skipping the resting time: Allowing the salted zucchini slices to rest for 15 minutes is essential. This step helps draw out moisture and enhances the texture. Don’t rush this process!
-
Not whisking well: When combining the cream sauce ingredients, make sure to whisk thoroughly. This prevents curdling and ensures a smooth sauce. Take your time during this step.
-
Ignoring baking times: Every oven is different, so keep an eye on your dish while it bakes. Cooking for too long or too little can affect browning and overall flavor. Adjust as needed based on appearance.
-
Forgetting the final cheese layer: The last sprinkle of parmesan and mozzarella is important for that golden, bubbly finish. Don’t skip this step for maximum flavor and presentation!
