Ingredients

Notes:

• Bread: Day-old bread works best as it absorbs the egg mixture well without becoming too soggy.
• Cheese: Feel free to mix different types of cheese for added flavor.
• Vegetables: You can customize the vegetable selection based on personal preference or seasonal availability.
• Meats: The addition of sausage or bacon is optional and can be substituted with cooked vegetables for a vegetarian version.

Cooking Steps

1. Preheat the oven to 175°C (350°F) and adjust the rack to the center position.
2. In a large mixing bowl, crack 8 large eggs and whisk together with 480 ml (2 cups) of milk until fully combined and frothy.
3. Add 1 teaspoon of salt, ½ teaspoon of pepper, ½ teaspoon of garlic powder (if using), and ½ teaspoon of mustard powder (if using) into the egg mixture, and whisk until incorporated.
4. In a large greased casserole dish (approximately 33 cm x 23 cm or 9 x 13 inches), evenly distribute the 6 cups of cubed bread.
5. Layer 1 cup of diced bell peppers and 1 medium diced onion over the cubed bread, followed by 1 cup of chopped fresh spinach (if using) and 1 cup of crumbled cooked sausage or bacon (if using).
6. Pour the egg mixture evenly over the entire bread and vegetable layer, ensuring all ingredients are moistened.
7. Press down gently with a spatula to help the bread absorb the egg mixture.
8. Sprinkle 2 cups of shredded cheese evenly over the top of the casserole.
9. Cover the dish tightly with aluminum foil and bake in the preheated oven for 35 minutes.
10. After 35 minutes, remove the foil and continue baking for an additional 10-15 minutes, or until the top is golden brown and the edges are set.
11. The internal temperature should reach at least 74°C (165°F).
12. Once baked, remove the casserole from the oven and let it rest for 10-15 minutes before slicing.
13. This allows for carryover cooking and helps firm up the texture.
14. Serve warm and garnish with ¼ cup of chopped fresh herbs (if using), ensuring a vibrant color and aromatic finish.
15. For leftovers, cool the casserole completely before covering and refrigerating; it can be reheated in the oven or microwave as needed.

Variations

• Mediterranean Delight: Swap bell peppers and onion for 1 cup of diced tomatoes, 1 cup of chopped kale, and adjust seasoning to include 1 teaspoon of oregano and feta cheese for a fresh twist.
• Southwest Fiesta: Replace the standard ingredients with 1 cup of black beans, 1 cup of corn, and diced jalapeños, topping with pepper jack cheese for a spicy kick.
• Vegetarian Veggie Medley: Omit the meat and use 2 cups of assorted vegetables like zucchini, mushrooms, and cherry tomatoes, and consider using a dairy-free cheese for a vegan option.
• Gluten-Free Goodness: Substitute cubed bread with 6 cups of gluten-free bread or a mix of quinoa and cooked sweet potatoes to make the dish suitable for gluten-sensitive diets.
