9 large eggs
2 ¾ cup milk
²/³ cup grated Parmesan
1 tsp. salt, divided
½ tsp. pepper, divided
2 cups coarsely grated Gruyere
1 ½ cups finely chopped onions
2 (10 oz.) pkgs. frozen spinach (thawed & drained)
8 cups cubed French or Italian bread (cut into 1" cubes--stale can work just as well as fresh)
Dash of nutmeg
Melt the butter in a skillet over medium heat. Add the onions and saute' until soft. Add ½ tsp. salt, ¼ tsp. pepper and the nutmeg. Continue to cook for 1 more minute. Stir in the spinach, remove from heat and set aside.
Butter (or use cooking spray) the inside of a 2½ - 3 quart baking dish. Layer the bottom of the dish with one third of the spinach and one third of each of the cheeses. Repeat the layers twice more.
In a medium bowl combine the eggs, milk and remaining salt & pepper. Whisk together until blended. Pour the mixture evenly over the bread & spinach. Cover with plastic wrap and chill for at least 8 hours or up to one day.
Remove from the refrigerator 30 minutes before baking. Bake uncovered for 45-55 minutes at 350 degrees. Let stand for five minutes before serving. Enjoy!
