    Tips for the Best Baked Zucchini Parmesan

    • Let Zucchini Sit After Salting: It’s important to let your zucchini slices rest for 15 minutes after salting them. This will allow the salt to draw moisture from the zucchini.
    • Coat Zucchini Slices with Cream: Be sure to toss your zucchini slices in the cream sauce until they’re covered so every bite is full of flavor!
    • Zucchini: If zucchini isn’t available or preferred, you can use other summer squash varieties like yellow squash.
    • Cheese: You can experiment with other cheese varieties like cheddar or Gouda. For a vegan version, use vegan cheese alternatives.
    • Garnish: You can garnish this dish with fresh basil to give it a pretty finishing touch.

    Prep Time 20 minutes mins

    Cook Time 20 minutes mins

    Total Time 40 minutes mins


    • 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


    • Preheat oven to 425˚F.

    • Butter a baking dish and set aside.

    • Cut the zucchini into ¼-inch slices and sprinkle salt on each slice. Let zucchini slices rest for 15 minutes so the salt can draw out the moisture.

    • Wipe each slice with a paper towel to remove the salt.

    • Arrange zucchini slices in the baking dish. Set aside.

    • In a mixing bowl whisk together heavy cream, sour cream, Italian seasoning, onion powder, salt, pepper, and ½ cup parmesan cheese. Set aside.

    • Melt the butter in a saucepan; stir in garlic and cook for 20 seconds.

    • To the saucepan, add in the heavy cream mixture; whisk and cook until mixture begins to bubble up. WHISK so that the cream does not start to curdle.

    • Stir in ½ cup mozzarella; cook for 20 more seconds or until cheese is all melted.

    • Pour the cream mixture over the zucchini in the baking dish; shake the baking dish to distribute the cream all around the zucchini slices.

    • Sprinkle the rest of the parmesan and mozzarella cheese over the zucchini.

    • Bake for 18 to 22 minutes, or until golden brown on top.

    • Remove from oven and let stand 5 minutes before serving.


    • Salting Zucchini: After adding salt, let the zucchini sit for 15 minutes. This helps pull out the moisture. I arrange the zucchini slices on a large baking sheet for this part. After 15 minutes, I wipe each slice with a paper towel to remove the salt.
    • Other Squash: No zucchini? No problem. Use yellow squash.
    • Change the Cheese: Try different cheeses like cheddar or Gouda.
    • Add Basil: Top the dish with fresh basil.
