Ingredients for Spinach and Gruyère Breakfast Strata

Main Ingredients
- 1 loaf of crusty bread, cut into 1-inch cubes (about 10 cups)
- 2 cups of fresh spinach, chopped
- 1 ½ cups of shredded Gruyère cheese
- 1 cup of milk
- 1 cup of heavy cream
- 8 large eggs
- 1 medium onion, finely chopped
- 2 cloves garlic, minced
- 2 tablespoons olive oil
- Salt and pepper to taste
- 1 teaspoon dried thyme
Optional Add-ins
- 1 cup of mushrooms, sliced
- ½ cup of sun-dried tomatoes, chopped
- ½ cup of cooked bacon or sausage, crumbled
- ¼ cup of fresh basil, chopped
Step-by-Step Cooking Instructions

Preparation Steps
- Prepare the Bread: Cut the loaf of bread into 1-inch cubes and let them sit out for a few hours or overnight to become slightly stale. This helps the bread absorb the custard mixture better.
- Sauté the Vegetables: In a large skillet, heat olive oil over medium heat. Add the chopped onion and sauté until translucent, about 5 minutes. Add the garlic and cook for another minute until fragrant.
- Add Spinach: Stir in the chopped spinach and cook until wilted, about 3 minutes. Remove from heat and set aside to cool slightly.
Cooking Process
- Preheat the Oven: Set your oven to 350°F (175°C) and grease a 9×13-inch baking dish.
- Mix the Custard: In a large bowl, whisk together the eggs, milk, heavy cream, salt, pepper, and dried thyme until well combined.
- Assemble the Strata: Layer half of the bread cubes in the prepared baking dish. Top with half of the spinach mixture and half of the shredded Gruyère cheese. Repeat with the remaining bread, spinach, and cheese.
- Add Optional Ingredients: If using any optional add-ins like mushrooms or bacon, sprinkle them evenly over the layers.
- Pour the Custard: Carefully pour the egg mixture over the layered bread and vegetables, pressing down gently to ensure the bread is submerged in the liquid.
- Bake: Cover the dish with aluminum foil and bake for 30 minutes. Remove the foil and bake for an additional 30 minutes, or until the top is golden and the custard is set.
- Cool and Serve: Allow the strata to cool for 10 minutes before slicing and serving. Enjoy this warm, cheesy delight!
Tips and Tricks for Perfect Results

Pro Chef Tips
For an extra burst of flavor, consider toasting the bread cubes in the oven for 10 minutes before assembling the strata. This step adds a delightful crunch to the final dish. Additionally, using day-old bread or allowing the bread to dry slightly ensures it soaks up the custard mixture effectively.
Common Mistakes to Avoid
A common pitfall is not allowing the strata to rest after baking. Resting for at least 10 minutes before cutting helps the layers set and makes serving easier. Additionally, avoid over-soaking the bread in the custard mixture as this can result in a soggy texture.
