Ingredients

• 8 cups, cubed day-old bread (such as French or sourdough)
• 6 cups fresh baby spinach
• 2 tablespoons butter
• 8 large eggs
• 2 cups whole milk
• 1 cup heavy cream
• 2 cups shredded cheddar cheese
• 0.5 cups grated Parmesan cheese
• 2 cloves garlic, minced
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 0.5 teaspoon dry mustard powder
• 1 tablespoon olive oil (optional, for greasing dish)

Directions

Step 1

Grease a 9x13-inch baking dish with olive oil or butter and set aside.

Step 2

Heat a large skillet over medium heat. Add the butter and minced garlic. Cook for 1 minute until fragrant.

Step 3

Add the baby spinach to the skillet and sauté until wilted, about 2-3 minutes. Remove from heat and set aside.

Step 4

In a large mixing bowl, whisk together the eggs, milk, heavy cream, salt, black pepper, and dry mustard powder.

Step 5

Add the cubed bread to the egg mixture and toss gently to coat. Let the bread soak for 10 minutes.

Step 6

Layer half of the soaked bread in the bottom of the prepared baking dish.

Step 7

Top the bread layer with half of the sautéed spinach, 1 cup of shredded cheddar cheese, and 1/4 cup of Parmesan cheese.

Step 8

Repeat with the remaining bread, spinach, cheddar cheese, and Parmesan cheese to create a second layer.

Step 9

Pour any remaining egg mixture evenly over the strata, pressing gently to ensure the bread absorbs the liquid.

Step 10

Cover the baking dish tightly with plastic wrap or aluminum foil and refrigerate for at least 6 hours, or overnight for best results.

Step 11

When ready to bake, preheat the oven to 350°F (175°C). Remove the strata from the refrigerator and let it sit at room temperature for 20 minutes.

Step 12

Bake the strata, uncovered, for 45-50 minutes, or until the top is golden brown and the custard is set.

Step 13

Remove the strata from the oven and let it cool for 5-10 minutes before serving. Slice into squares and enjoy!
