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
Cook Time 20 minutes
Total Time 40 minutes

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

Instructions
 

  • 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.

Notes

  • 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.
