For 4 servings
- prep · ~15 min
Salt the zucchini slices to draw out moisture.
Spread zucchini rounds on paper towels, sprinkle with ¼ teaspoon salt, and let sit 15 minutes. Pat dry thoroughly with more paper towels — removing excess water helps them bake crispy.
TIPDon't skip salting — it pulls out moisture that would otherwise steam the zucchini in the oven. - prep · ~5 min
Preheat the oven and set up the breading station.
Preheat oven to 425°F. Line a baking sheet with parchment paper and brush lightly with olive oil. In one shallow bowl, combine breadcrumbs, Parmesan, garlic powder, oregano, remaining ¼ teaspoon salt, and black pepper. In another bowl, beat the eggs until smooth.

Bread the zucchini rounds.
1.Dip each zucchini round into beaten egg, letting excess drip off.2.Press firmly into the breadcrumb-Parmesan mixture until well coated on both sides.3.Arrange in a single layer on the prepared baking sheet.TIPUse one hand for wet (egg) and one hand for dry (crumbs) to avoid clumpy fingers. - bake · ~20 min
Bake the zucchini until golden and crisp.
Place the baking sheet on the middle rack and bake for 12 minutes. Flip each round, then bake another 8-10 minutes until both sides are golden and crisp at the edges.
TIPWatch the second side carefully — Parmesan can go from golden to burnt quickly. - assemble · ~5 min

Bake the assembled casserole until bubbly and golden.
Place the dish on the middle rack and bake at 425°F for 10-12 minutes, until the sauce bubbles and the cheese on top is melted with golden spots. Switch to broil for 1-2 minutes if you want a darker cheesy crust.
TIPBroil only at the end and don't walk away — cheese can go from browned to burned in seconds. - rest · ~5 min
Rest before serving.
Let the dish rest for 5 minutes so the layers set and don't slide apart when scooped.
TIPServing too soon causes the sauce and cheese to slide off — a short rest makes all the difference. - garnish
Garnish with fresh basil and serve hot.
Scatter chopped basil over the top and scoop generous portions onto plates.
