Ingredients
- 4 medium Zucchini
- 1 small Yellow onion
- 2 cloves Garlic
- 2 large Eggs
- 1 cup Sour cream
- 1 1/2 cups Shredded cheddar cheese
- 1 cup Shredded mozzarella cheese
- 1/2 cup Parmesan cheese
- 3/4 cup Panko breadcrumbs
- 2 tablespoons Olive oil
- 1 teaspoon Salt
- 1/2 teaspoon Black pepper
- 1 teaspoon Italian seasoning
Instructions
- The zucchini changes from whole vegetables into uneven half moon slices with pale centers and green edges. The slices are tossed with onion, garlic, oil, salt, pepper, and Italian seasoning so the surfaces look lightly glossy and speckled.
- The filling becomes thick and pale as eggs and sour cream blend together. Cheddar, mozzarella, and Parmesan are folded in so the mixture looks creamy with uneven shreds of cheese throughout.
- The glossy zucchini slices disappear partly into the creamy cheese mixture while some green edges remain visible. The mixture becomes thicker and more structured with vegetables and cheese unevenly folded together.
- The coated zucchini mixture moves into a ceramic baking dish and becomes a thick uneven layer. The top is scattered with panko and extra cheese so the surface changes from creamy to textured and ready to brown.
- The casserole changes into a bubbling baked dish with softened zucchini beneath melted cheese. The panko turns golden in uneven patches while the creamy edges look thick and slightly browned.
- A single portion is lifted from the casserole and placed on a white plate so the inside texture shows clearly. The slice has soft zucchini layers, creamy melted cheese, golden crumbs, and slightly messy edges that look homemade.
Notes
Pro Tips:
- Salt the zucchini lightly and avoid overmixing so the casserole stays creamy instead of watery.
- Use freshly shredded cheese for the smoothest melt and the best golden baked top.
- Let the casserole rest for several minutes before serving so the slices hold their shape.
- Add breadcrumbs only on top so they stay crisp while the zucchini underneath remains tender.
Storage: Store leftover Cheesy Zucchini Casserole in an airtight container in the refrigerator for up to 4 days. Let the casserole cool before covering so steam does not make the topping too soft. Reheat single portions in the oven or air fryer when you want the top to crisp again. For freezing, wrap portions tightly and thaw overnight before reheating until hot in the center.
