Steam and Drain the Zucchini
Steam the zucchini only until crisp-tender, then give it time to drain thoroughly so the casserole does not become watery.

Drain the zucchini well so the beef-and-tomato filling bakes up hearty rather than watery. The Parmesan browns across the top, with green olives adding a surprising salty bite underneath.
This Zucchini Casserole turns a generous pile of zucchini into a family-style supper with seasoned beef, tomatoes, green olives, herbs, and Parmesan. The filling stays hearty without burying the zucchini, making it especially good with Cheesy French Bread or a simple salad.

I drain the zucchini really well because a watery casserole never bakes up right. Sometimes I add mozzarella over the top, too—the browned cheese around the edges is hard to resist when it comes out bubbling hot.

Steam the zucchini only until crisp-tender, then give it time to drain thoroughly so the casserole does not become watery.

Brown the beef with onion, green pepper, and garlic. Add the tomatoes, tomato paste, and herbs, then simmer until the filling is thick.

Alternate the drained zucchini and tomato-beef filling in a prepared casserole dish.

Finish with green olives, thin onion slices, and Parmesan, then bake until bubbling and lightly browned.
