How to Make Easy Overnight Breakfast Casserole

  1. Prepare the Bread: Cut your bread into cubes and place it in a large mixing bowl. Feel free to toast the bread slightly for added texture.

  2. Cook the Meat: In a skillet, cook the bacon or sausage until crispy. As the sizzle fills your kitchen, you’ll know it’s almost time to feast! Drain excess fat and let it cool slightly.

  3. Sauté the Vegetables: In the same pan, sauté diced onion and bell peppers until they’re soft and fragrant. Add the spinach just until wilted.

  4. Mix the Eggs and Milk: In another bowl, whisk together the eggs and milk until well combined. Add a pinch of salt and pepper.

  5. Combine Everything: Fold the meat and vegetable mixture into the bread cubes. Then pour the egg mixture over everything, stirring gently to combine.

  6. Add Cheese: Sprinkle half of your cheese into the mixture, reserving the other half for topping.

  7. Transfer to Baking Dish: Pour everything into a greased 9×13-inch baking dish. Cover with plastic wrap and let chill in the refrigerator overnight.

  8. Bake: Preheat your oven to 350°F (175°C). Uncover the casserole and top with the remaining cheese. Bake for 45-50 minutes until the top is golden brown and the center is set.

  9. Serve and Enjoy: Let it sit for 5-10 minutes before slicing into squares. Serve warm with a side of fresh fruit or a zesty breakfast cocktail—what a way to start the day!

Tips and Creative Variations

  • Spicy Kick: Add chopped jalapeños or a dash of hot sauce for some heat.
  • Herbs and Spices: Try adding thyme or rosemary for an aromatic twist.
  • Sweet Addition: For a sweet spin, drizzle with maple syrup before serving.
  • Gluten-Free: Substitute with your favorite gluten-free bread and ensure your sausage is gluten-free.
  • Cheese Choices: Experiment with feta or goat cheese for a tangy touch.
