Ingredients

• 2 tablespoons olive oil
• 1 tablespoon butter
• 1 medium yellow onion, diced
• 2 cloves garlic, minced
• 8 ounces mushrooms, sliced
• 6 cups fresh spinach
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 6 cups day-old bread, cubed
• 1.5 cups shredded Gruyere cheese
• 0.5 cups shredded Parmesan cheese
• 6 large eggs
• 2 cups milk
• 0.5 cups heavy cream
• 1 tablespoon Dijon mustard

Directions

Step 1

Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking dish.

Step 2

Heat the olive oil and butter in a large skillet over medium heat. Add the onion and sauté for 3-4 minutes until softened.

Step 3

Stir in the garlic and cook for another minute, until fragrant.

Step 4

Add the sliced mushrooms to the skillet and cook for 5-7 minutes, stirring occasionally, until the mushrooms release their moisture and are browned.

Step 5

Add the spinach to the skillet in batches, stirring to wilt. Once all the spinach is wilted, season with salt and black pepper. Remove from heat and set aside.

Step 6

In a large mixing bowl, combine the cubed bread and the spinach-mushroom mixture. Toss to combine evenly and transfer the mixture to the prepared baking dish.

Step 7

In another bowl, whisk together the eggs, milk, heavy cream, and Dijon mustard until well blended. Pour this mixture evenly over the bread mixture in the baking dish.

Step 8

Sprinkle the shredded Gruyere and Parmesan cheeses evenly over the top.

Step 9

Allow the strata to rest for 15-20 minutes so the bread can absorb the custard mixture. Alternatively, cover and refrigerate it overnight.

Step 10

Bake in the preheated oven for 45-50 minutes, or until the top is golden brown and the custard is set.

Step 11

Remove from the oven and let the strata cool for 5-10 minutes before slicing and serving. Enjoy!
