📝 Instructions

17 steps

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

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

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

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

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

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

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.

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

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

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

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

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

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

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

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

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

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