Ingredients
Zucchini Preparation
- 2 pounds zucchini (cut into 1/4-inch slices)
- Salt for zucchini
Cream Sauce
- 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: Preheat your oven to 425˚F to prepare for baking the zucchini casserole.
- Prepare Baking Dish: Lightly butter a baking dish to prevent sticking and set it aside for later use.
- Salt Zucchini: Slice the zucchini into ¼-inch thick rounds and sprinkle salt evenly over each slice. Let them rest for 15 minutes to draw out excess moisture through osmosis.
- Remove Moisture: After resting, gently pat each zucchini slice dry with a paper towel to remove the drawn-out salt and moisture.
- Arrange Zucchini: Place the dried zucchini slices evenly in the prepared baking dish and set aside.
- Mix Cream Sauce: In a mixing bowl, whisk together the heavy cream, sour cream, Italian seasoning, onion powder, salt, black pepper, and ½ cup of grated parmesan cheese until fully combined.
- Melt Butter and Sauté Garlic: In a saucepan, melt the butter over medium heat and quickly sauté the minced garlic for about 20 seconds until fragrant without browning.
- Add Cream Mixture: Pour the whisked cream mixture into the saucepan with the garlic, stirring constantly. Heat until the mixture begins to bubble gently, being careful to whisk continuously to prevent curdling.
- Incorporate Mozzarella: Stir in ½ cup of shredded mozzarella cheese into the warm cream sauce, cooking for an additional 20 seconds or until the cheese is fully melted and the sauce is smooth.
- Pour Sauce Over Zucchini: Pour the prepared creamy cheese sauce evenly over the zucchini slices in the baking dish, gently shaking the dish to distribute the sauce thoroughly.
- Top with Remaining Cheese: Sprinkle the remaining ½ cup parmesan cheese and ½ cup mozzarella cheese evenly over the top of the zucchini and sauce layer.
- Bake: Place the baking dish in the preheated oven and bake for 18 to 22 minutes, or until the top is golden brown and bubbly.
- Rest and Serve: Remove from the oven and let the dish stand for 5 to 10 minutes before serving to allow the sauce to thicken and flavors to meld.
Notes
- Salting the zucchini and letting it rest helps remove excess water, preventing a watery casserole.
- Use freshly grated parmesan and shredded mozzarella for best melting and flavor.
- Keep an eye on the sauce while heating to avoid curdling by whisking constantly.
- Letting the casserole rest after baking improves texture and makes serving easier.
- For a lighter version, substitute heavy cream with half-and-half and use reduced-fat cheeses.
