This recipe is from Everyday Food Magazine. I really enjoyed this dish. It is a keeper .
1 teaspoon extra-virgin olive oil
10 ounces spinach
3 cups day-old bread cubes (1 inch)
5 large eggs, lightly beaten
1 cup whole milk
1 1/4 cups grated sharp white cheddar (3 ounces)
Coarse salt and ground pepper
Preheat oven to 400 degrees. In a large skillet, heat oil over medium-high. Add spinach and cook, stirring constantly, until wilted, about 2 minutes. Transfer to a colander and drain, pressing with a rubber spatula to release as much liquid as possible. Divide bread and spinach among four small, shallow 8-ounce baking dishes.
In a medium bowl, whisk together eggs, milk, and 3/4 cup cheese. Season with 1/2 teaspoon salt and 1/4 teaspoon pepper. Divide mixture evenly among baking dishes and top with 1/2 cup cheese. Set dishes on a rimmed baking sheet and bake until set in middle and golden brown on top, 20 to 25 minutes.
