Vegetarian Spring Egg Casserole

Serves 8

Active Time: 25 minutes

Total Time: 9 hours, 15 minutes

3 tablespoons unsalted butter

1 1/2 cups chopped scallions

4 cloves garlic, finely chopped

6 ounces fresh baby spinach (about 10 cups), chopped

1 cup whole milk

4 ounces reduced-fat cream cheese, softened

6 large eggs, beaten

3/4 cup shredded whole-milk mozzarella cheese

1/2 teaspoon salt

8 ounces whole-grain crusty bread, cut into 1-inch cubes (about 5 cups)

12 ounces asparagus, trimmed and cut into 1-inch pieces

1. Melt butter in a large skillet over medium-high heat. Add scallions and garlic; cook, stirring occasionally, until slightly softened, about 2 minutes. Add spinach; cook, stirring often, until starting to wilt, about 1 minute. Remove from heat.

2. Whisk milk and cream cheese in a large bowl until combined. Stir in eggs, mozzarella and salt. Stir in bread cubes and asparagus until well coated. Stir in spinach mixture. Pour into a 9-by-13-inch baking dish coated with cooking spray. Cover with foil; chill for at least 8 hours or up to 24 hours.

3. Preheat oven to 350 F. Bake the casserole, covered, for 30 minutes. Uncover; continue baking until the top is browned and the custard is set, 25 to 30 minutes more.

To make ahead: Prepare through Step 2; cover and refrigerate overnight.
