Martha Stewart’s English Muffin & Ham Breakfast Strata

Ingredients :

• Cooking spray
• English muffins
• 1/2 pound sliced ham (or Canadian bacon), cut into halves
• 8 eggs
• 2 egg whites
• 2 cups milk
• 1/2 cup sour cream
• 1/4 cup parmesan cheese, shredded
• 2 1/2 cups cheddar cheese, shredded

Instructions : 

1. Prepare 9×13 baking dish with cooking spray and set aside. In the dish, alternately arrange muffin halves and meat, overlapping slightly.
2. Sprinkle with cheddar and Parmesan cheeses. Set aside.
3. In a large bowl: whisk together eggs, egg whites, milk, sour cream and pepper until combined. Pour over muffin, ham and cheese layers. Cover entire dish tightly with plastic wrap. Refrigerate at least 2 hours and up to overnight.
4. Preheat oven to 350 degrees fahrenheit. Bake strata, uncovered, until puffed and set in the center, approximately 60-80 minutes. If strata begins to brown before puffing up, cover loosely with foil to prevent burning.
5. Let stand 10 minutes before cutting and serving.
