How to Make Creamy Parmesan Zucchini
Step 1: Preheat the Oven
Preheat your oven to 425˚F. This ensures that your creamy Parmesan Zucchini bakes evenly.
Step 2: Prepare the Baking Dish
Butter a baking dish generously. Set it aside for later use.
Step 3: Slice the Zucchini
Cut the zucchini into ¼-inch slices. Sprinkle salt on each slice and let them rest for 15 minutes. This step draws out excess moisture from the zucchini.
Step 4: Remove Excess Salt
After letting them rest, wipe each zucchini slice with a paper towel to remove excess salt.
Step 5: Arrange Zucchini in Dish
Arrange the salted zucchini slices neatly in the buttered baking dish. Set aside while you prepare the cream sauce.
Step 6: Prepare the Cream Mixture
In a mixing bowl, whisk together heavy cream, sour cream, Italian seasoning, onion powder, salt, pepper, and ½ cup of parmesan cheese until well combined. Set aside.
Step 7: Sauté Garlic
In a saucepan over medium heat, melt the butter. Add finely minced garlic and cook for about 20 seconds until fragrant.
Step 8: Combine Mixtures
Pour in the heavy cream mixture into the saucepan with garlic. Whisk continuously until it begins to bubble up to prevent curdling.
Step 9: Add Cheese
Stir in ½ cup of mozzarella cheese into the bubbling mixture. Cook for another 20 seconds or until melted thoroughly.
Step 10: Pour Over Zucchini
Pour the hot cream mixture evenly over the arranged zucchini in the baking dish. Shake gently to ensure all slices are coated.
Step 11: Add Toppings
Sprinkle remaining parmesan and mozzarella cheese on top of the zucchini for an extra cheesy finish.
Step 12: Bake Until Golden
Bake in your preheated oven for about 18 to 22 minutes or until golden brown on top.
Step 13: Let Stand Before Serving
Once out of the oven, let your creamy Parmesan Zucchini stand for about 5 to 10 minutes before serving. This allows flavors to meld beautifully.
