Main Ingredients

Ingredient	Quantity
Zucchini (sliced into ¼-inch half-moons)	6 cups (about 2-4 zucchini)
Salt	¼ teaspoon
Heavy cream	⅓ cup
Whole eggs	3
Parmesan cheese (grated)	¼ cup
Garlic (minced)	3-4 cloves
Dried basil	1 teaspoon
Black pepper (freshly ground)	¼ teaspoon, or to taste
Ground nutmeg	⅛ teaspoon
Shredded cheddar cheese	1½ cups (divided)
Butter (sliced into ¼-inch pieces)	2 tablespoons
Fresh parsley (chopped)	For garnish

Step-by-Step Instructions

1. Preheat the Oven and Prepare the Zucchini

• Preheat your oven to 375°F (190°C).
• Toss the sliced zucchini with ¼ teaspoon salt and let it sit for 10 minutes. This helps draw out excess moisture so the casserole doesn’t become watery.
• After 10 minutes, pat the zucchini dry with paper towels to remove excess water.

2. Prepare the Custard Mixture

In a large mixing bowl, whisk together:

• Heavy cream
• Eggs
• Grated Parmesan
• Minced garlic
• Dried basil, black pepper, and nutmeg

This mixture forms the rich, creamy base of the casserole.

3. Assemble the Casserole

• Lightly grease a medium-sized baking dish with butter or cooking spray.
• Layer half of the zucchini at the bottom of the dish.
• Sprinkle half of the shredded cheddar cheese over the zucchini.
• Pour half of the custard mixture evenly over the layers.
• Repeat with the remaining zucchini, cheddar cheese, and custard mixture.
• Dot the top with sliced butter for extra richness.

4. Bake Until Golden and Set

• Place the casserole in the preheated oven and bake for 35-45 minutes, or until the top is golden brown and the center is firm.

5. Garnish and Serve

• Let the casserole sit for 5-10 minutes before serving. This allows the flavors to meld and the texture to set.
• Garnish with chopped fresh parsley for a pop of color and added freshness.

Expert Tips for the Best Zucchini Casserole

1. Avoid a Watery Casserole

Zucchini holds a lot of water, which can make your casserole soggy. Salting and patting it dry before baking helps remove excess moisture.

2. Use Freshly Grated Cheese

Pre-packaged shredded cheese contains anti-caking agents that can affect melting. Grating fresh cheese results in better texture and flavor.

3. Try Different Herbs and Spices

For extra depth, add onion powder, thyme, or red pepper flakes.

4. Use a High-Quality Baking Dish

A ceramic or glass baking dish helps distribute heat evenly, ensuring a perfectly baked casserole.

5. Add a Crispy Topping

For added crunch, sprinkle toasted breadcrumbs or crushed pork rinds on top before baking.
