What’s in Zucchini Parmesan?

  • Zucchini: Cut your zucchini into 1/4-inch slices.
  • Sour Cream
  • Heavy Cream
  • Garlic: Finely mince your garlic to distribute its flavor throughout this dish!
  • Italian Seasoning
  • Onion Powder
  • Salt & Pepper
  • Parmesan Cheese
  • Butter

How to Make Parmesan Baked Zucchini

  1. Prepare for Baking: Preheat your oven to 425˚F. Butter a 3-quart baking dish and set it aside.
  2. 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.
  3. Place in Baking Dish: Arrange your zucchini slices in the baking dish and set it aside.
  4. Melt butter in a saucepan.
  5. 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.
  6. 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.
  7. Add Cheese: Sprinkle the rest of the parmesan and mozzarella cheese over the zucchini.
  8. Bake: Bake until bubbly and the top gets golden brown.
  9. 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.

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.

    Followed the recipe precisely, but this was way too salty for us. I’d make it again (because we’re overflowing with zucchini), but not add any salt to the cream mixture. And YES, I did wipe off each zucchini slice with paper towel – very thoroughly.

      Hi! Yes, I am definitely posting WW points, but I’m running a bit behind. I’m hoping to have it all updated by the end of the weekend.
      I just added the Points for the Baked Zucchini.

    Gave this a try for dinner the other night and it was exactly what I hoped for! A great way to get picky eaters to eat (and enjoy) their veggies, too!

  3. Jen

    I’ve been trying to add more meatless meals into our rotation and this one was sure a hit! It’s so cheesy and delicious!

  4. Lily

    This was delicious I love how versatile it was. We used it as a dip with toasted bread and then as a side for grilled chicken, this was a fantastic recipe.
