Christmas Morning Strata

Every Christmas our family joins us for brunch at our home after we have finished opening our presents. We look forward to this strata as the main part of our meal.
12-18 slices white bread, crusts removed
1 lb baby asparagus, broken into pieces
1 1/2 lbs sausage (mild)
1 lb grated cheddar cheese
12 eggs (or 3 cups egg beaters)
1 cup sour cream or buttermilk (I use sour cream)
salt/pepper to taste
dash of Worcestershire sauce
3 to 4 green onions, chopped

Butter 9x13 baking dish, set aside. Steam asparagus for 2 minutes, drain, rinse with cold water. Brown sausage and green onions; drain well. Blend eggs, sour cream and seasonings. In pan, layer as follows: 1/2 of the bread, 1/2 of the cheese, 1/2 of the sausage, 1/2 of the asparagus. Repeat. Pour the egg mixture over all. Cover and refrigerate overnight. Remove from fridge and let sit at room temperature for 1 hour before baking. Bake uncovered at 350 degrees for one hour, or until knife inserted comes out clean. Serve warm.
