Zucchini Quiche Recipe: How to Make a Cheesy Zucchini Quiche

Quiche is a savory French tart with a delicate, flaky crust and a custardy egg filling packed with various ingredients—from sharp, salty ham and soft cheeses to roasted vegetables and pine nuts. Cheesy zucchini quiche features sautéed zucchinis (sautéing removes their water), creamy cheeses, and fresh herbs. Serve this simple vegetarian dish (or side dish) hot, cold, or at room temperature.

Quiche is a versatile dish that is quick to assemble and even more delicious the next day. Here are some tips for preparing and baking it to perfection:

1. 1. Go crustless. Skip the crust for those with keto or gluten-free diets and make a crustless zucchini quiche (also known as a frittata, an Italian baked egg dish). Add your favorite fillings, just as you would when making quiche—simply prepare the dish in a cast-iron skillet on the stovetop and finish it in the oven.

2. 2. DIY the crust. You can certainly use a time-saving frozen premade crust to make a quiche. But for the best flavor, try a homemade pie dough recipe. All you need is all-purpose flour, butter, and some salt. Use a deep-dish pie pan to ensure you can fill it generously with the zucchini.
3. 3. Blind-bake your crust. If you’re making crust from scratch, give it an initial bake before adding the wet ingredients, using a technique known as blind-baking. A blind-bake prevents your crust from getting soggy when adding your egg mixture.
4. 4. Use just the right amount of eggs. If the ratio between the eggs and milk isn’t right in your custard mixture, you can end up with a firm, rubbery quiche. Use a half-cup of dairy for every egg you use in your custard mixture for a simple, go-to ratio.
5. 5. Bake it on the bottom rack of the oven. Placing your quiche on the lowest shelf of your oven will allow the whole crust to crisp up properly. Placing it too high in the oven can result in an uneven bake.

You can store leftover quiche in the pie plate, covered with plastic wrap or a lid, or transfer individual slices to an airtight container. Cooked quiche will keep in the refrigerator for up to three days. Reheat leftover quiche in an oven-safe pie dish in a 250-degree-Fahrenheit oven or place individual slices on a baking sheet. Alternatively, use a toaster oven on the lowest setting.
