🔪EQUIPMENT YOU’LL NEED
| Equipment | Why You Need It |
|---|---|
| 9-inch baking dish | The standard size for even cooking — ceramic or glass both work perfectly |
| Mixing bowl (medium) | For whisking the creamy egg mixture |
| Whisk | Ensures a smooth, lump-free custard base |

👩🍳Directions
1. Prepare the Zucchini
- Preheat the oven to 350°F (175°C) and grease a 9-inch baking dish with butter.
- Arrange sliced zucchini in the baking dish, sprinkle with salt, and let it sit for a few minutes to release excess moisture.
2. Make the Creamy Mixture
- In a mixing bowl, whisk together heavy cream, eggs, Parmesan cheese, garlic, basil, black pepper, and nutmeg.
- Pour the mixture over the zucchini to create a rich and creamy base.
3. Assemble the Casserole
- Sprinkle 1/2 cup shredded cheddar cheese evenly over the zucchini.
- Pour the prepared cream sauce over the dish, then drizzle melted butter for extra richness.
4. Bake the Casserole
- Bake uncovered for 25 minutes, then remove from the oven and sprinkle with the remaining cheddar cheese.
- Bake for another 7-10 minutes, or until bubbly and golden brown.
5. Serve & Enjoy
- Let the casserole rest for 10 minutes before slicing.
- Garnish with fresh parsley for a burst of color and serve warm!

❓FAQs
1. Can I make zucchini casserole without cheese or dairy?
Yes! Use nutritional yeast for a cheesy flavor and swap heavy cream for full-fat coconut milk or blended cashews. The texture stays creamy and the result is surprisingly satisfying — even for non-vegans.
2. How do I prevent my zucchini casserole from becoming watery?
Salt your sliced zucchini and let it drain in a colander for 10–15 minutes, then pat dry with paper towels before assembling. This single step makes the biggest difference. You can also pre-roast slices at 400°F for 8 minutes to drive off moisture before baking.
3. Can I prep this casserole the night before?
Absolutely. Assemble the entire casserole (without baking), cover tightly with plastic wrap, and refrigerate overnight. Bake directly from the fridge — just add 5–8 extra minutes to the cooking time.
4. Can I freeze zucchini casserole?
Yes, for up to 1 month. Freeze in individual portions in airtight containers. Thaw overnight in the fridge, then reheat at 350°F for 15 minutes. Note: the texture becomes slightly softer after freezing, which many kids actually prefer.
5. Is this recipe suitable for picky eaters?
Very much so. The golden cheese crust is visually appealing, the zucchini becomes soft and mild, and the overall flavor is familiar comfort-food territory. Cut into small squares and serve with a dipping sauce (mild tomato, ranch) to boost acceptance.
6. Can I add a crunchy topping?
Yes! Sprinkle panko breadcrumbs, crushed crackers, or toasted pine nuts in the last 10 minutes of baking. For a keto version, crushed pork rinds work surprisingly well and add great texture.
