This creamy Parmesan Zucchini is the ultimate vegetarian dinner recipe! Fresh zucchini slices are covered with cream sauce and baked until bubbly and golden.
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 to 10 minutes before serving.
Notes
Salting Zucchini: After adding salt, let the zucchini sit for 15 minutes. This helps pull out the moisture. For this part, I arrange the zucchini slices on a large baking sheet. After 15 minutes, I wipe each slice with a paper towel to remove the salt.
Other Squash: No zucchini? Use yellow squash.
Change the Cheese: Try different cheeses like cheddar or Gouda.
