Ingredients

• 8 cups day-old bread (French or sourdough)
• 2 tablespoons butter
• 1 tablespoon olive oil
• 1 medium onion, finely chopped
• 2 cloves garlic, minced
• 8 ounces mushrooms, sliced
• 5 cups fresh spinach
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 8 eggs
• 2.5 cups milk
• 1 tablespoon Dijon mustard
• 2 cups shredded cheese (Gruyere, cheddar, or mozzarella)
• 0.5 cup Parmesan cheese, grated
• 2 tablespoons chopped fresh parsley

Directions

Step 1

Grease a 9x13-inch baking dish with butter or nonstick spray.

Step 2

Cut the bread into 1-inch cubes and spread them evenly in the baking dish.

Step 3

Heat the butter and olive oil in a large skillet over medium heat.

Step 4

Add the chopped onion to the skillet and sauté for 3 minutes, until translucent.

Step 5

Stir in the garlic and cook for another 30 seconds until fragrant.

Step 6

Add the mushrooms to the skillet and cook for 5-7 minutes, until they release their moisture and begin to brown.

Step 7

Toss in the fresh spinach and sauté for 2-3 minutes, until wilted. Season with 1/2 teaspoon salt and 1/4 teaspoon pepper.

Step 8

Remove the skillet from heat and set the vegetable mixture aside to cool slightly.

Step 9

In a large mixing bowl, whisk together the eggs, milk, Dijon mustard, remaining salt, and pepper until well combined.

Step 10

Layer the cooled vegetable mixture over the bread cubes in the baking dish, spreading evenly.

Step 11

Pour the egg mixture evenly over the bread and vegetables, pressing gently to ensure the bread absorbs the liquid.

Step 12

Sprinkle shredded cheese evenly across the top, followed by grated Parmesan cheese.

Step 13

Cover the dish with foil and refrigerate for at least 2 hours or overnight for best results.

Step 14

When ready to bake, preheat the oven to 350°F (175°C).

Step 15

Bake the strata, covered with foil, for 30 minutes.

Step 16

Remove the foil and bake for an additional 15 minutes, until the top is golden and the strata is set in the center.

Step 17

Let the strata rest for 10 minutes before garnishing with fresh parsley and serving.
