How to Make Parmesan Baked Zucchini
- Prepare for Baking: Preheat your oven to 425˚F. Butter a 3-quart baking dish and set it aside.
- Salt Zucchini: Sprinkle salt on each 1/4-inch slice of zucchini. Let zucchini slices rest for 15 minutes after salting. (For this part, I lay the zucchini slices on a large baking sheet.) Then, wipe each of the slices with a paper towel to remove the salt.
- Place in Baking Dish: Arrange your zucchini slices in the baking dish and set it aside.
- Melt butter in a saucepan.
- Make Cream Sauce: In a mixing bowl, combine heavy cream, sour cream, garlic, Italian seasoning, onion powder, salt, pepper and ½ cup parmesan cheese. Add sour cream mixture to the saucepan and whisk until it starts to bubble.
- Add to Baking Dish: Pour the cream mixture over the zucchini and shake the baking dish to distribute the cream all around the zucchini slices.
- Add Cheese: Sprinkle the rest of the parmesan and mozzarella cheese over the zucchini.
- Bake: Bake until bubbly and the top gets golden brown.
- Let Cool: Remove your dish from the oven and let it stand for 5 minutes before serving.
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!
- Garnish: You can garnish this dish with fresh basil to give it a pretty finishing touch.
- Bread: Serve this creamy zucchini casserole with my fluffy Slow Cooker Basil Pesto Bread. It’s great for dipping into the extra cream sauce! 😋
- Corn on the Cob: My Grilled Corn with Herbed Butter tastes amazing with parmesan baked zucchini.
- Chicken: If you eat meat, you have to try serving this dish with these Juicy Garlic Butter Pan Fried Chicken Breasts.
- Pasta: This creamy zucchini recipe also goes well with my easy Olive Pesto Pasta! 👈 so good!
How to Store and Reheat Leftovers
- You can store your leftovers in the fridge for 2-3 days if you keep them in an airtight container. To reheat your zucchini, bake it at 350°F until it’s hot and the cheese starts bubbling.
