1Preheat oven to 350 degrees F (175 degrees C). Grease two 9x9-inch baking dishes.
2Heat butter in a skillet over low heat; cook and stir zucchini, onion, garlic, Italian seasoning, salt, and black pepper in the melted butter until zucchini and onion are tender, about 10 minutes. Drain any excess liquid from zucchini. Remove skillet from heat and cool, 15 to 20 minutes.
3Whisk half-and-half and eggs together in a bowl; stir in zucchini mixture, mozzarella cheese, Havarti cheese, and nutmeg. Season with salt and pepper.
4Unroll crescent roll dough and tear sheet in half. Press each half into the prepared baking dishes, forming a crust. Pour egg mixture evenly into each crust.
5Bake in the preheated oven until crust is golden and quiche is set in the middle, about 45 minutes.
Footnotes
Cook's Note:
You can add basically any vegetable to this recipe by subbing out some of the zucchini. Can also add bacon, sausage, or ham very easily by slicing the cooked meat and adding it to the zucchini mixture after everything is cooled. You can use any cheese; these were just my favorites.
