1-First step: Prepare the oven and dish Start by preheating your oven to 350°F (175°C). Grease a quiche dish, pie dish, or casserole dish well so the pie releases easily after baking. A standard 9-inch pie dish works well, but any similar baking dish will do. If you want extra protection against spills, place the dish on a foil-lined baking sheet before it goes into the oven.

2-Second step: Prep the zucchini Grate the zucchini until you have 2 cups, which is about 2 medium zucchini. Put the grated zucchini in a bowl and add a pinch of salt. Let it sit for a few minutes. This helps draw out extra moisture, which is key for a firm, sliceable crustless quiche. After it rests, squeeze the zucchini well with clean hands, a kitchen towel, or cheesecloth. Try to get out as much liquid as possible. This step matters a lot because zucchini can release a surprising amount of water while it bakes. If you skip it, the center may stay too soft.

3-Third step: Mix the batter In a large bowl, whisk together 4 eggs, 2 cups milk, 3/4 cup flour, and 1 teaspoon baking powder until smooth. You want a batter with no dry flour lumps. A whisk works best here, but a fork can work if that is all you have. Once the base looks smooth, stir in 1 cup diced ham, the squeezed zucchini, 8 ounces grated cheddar cheese, 1 pinch salt, and 1 pinch black pepper. Mix just until everything is evenly distributed. Do not overmix, or the texture may get dense.

4-Fourth step: Pour and spread Pour the batter into the prepared dish and spread it out evenly with a spoon or spatula. The batter will look fairly loose, but that is normal. The flour, eggs, and cheese will help it set as it bakes. If you are using a glass or ceramic pie dish, keep in mind that bake times can vary a little depending on your oven. Metal pans may brown the edges a bit faster. For best results, keep an eye on the top during the last 10 minutes of baking.

5-Fifth step: Bake until set Bake the ham zucchini quiche for about 45 minutes, or until it is golden brown and set in the center. The top should look puffed and lightly browned, and a knife inserted near the center should come out mostly clean. If the edges are browning too quickly, loosely cover the dish with foil during the last part of baking. Because ovens vary, begin checking at around 40 minutes. The pie should still have a slight wobble in the very center, but it should not look wet.

6-Final step: Rest, slice, and serve When the pie is done, let it cool for at least 10 minutes before slicing. This resting time helps the filling firm up so the pieces hold together better. Serve it warm for a cozy meal, or let it come to room temperature if you are packing it for lunch or a potluck. This crustless ham zucchini quiche is especially nice with a green salad, sliced tomatoes, or fresh fruit on the side. It works for breakfast, brunch, lunch, or a light dinner. If you are cooking for guests, you can cut it into neat wedges and serve it with herbs sprinkled on top.
