Step-by-Step Instructions
- In a large mixing bowl, whisk together 2 cups of whole milk, 8 large eggs, 2 tablespoons of Dijon mustard, and a pinch of red pepper flakes until well combined.
- In a skillet over medium-high heat, melt 2 tablespoons of unsalted butter. Add 3 cloves of minced garlic, 4 sliced green onions, and 1 ½ cups of thawed, squeezed-dry frozen chopped spinach. Sauté for about 4 minutes.
- Grease an 11x13-inch casserole dish with butter. Place 6 cups of cubed challah bread in the dish, spreading it out evenly. Pour the sautéed spinach mixture over the bread and gently toss.
- Slowly pour the whisked milk and egg mixture evenly over the bread and stir in ¾ cup each of shredded extra-sharp cheddar, Gruyere, and Parmesan cheese.
- Cover the dish tightly and refrigerate for at least 8 hours, preferably overnight.
- Preheat oven to 375°F. Allow strata to sit at room temperature for about 30 minutes. Sprinkle remaining cheese and crumbled bacon on top.
- Bake for about 30 minutes until the top is puffed and golden brown. Allow to cool slightly before slicing.
