Equipment
- 9x13 inch baking dish
- large bowl
- plastic wrap
Ingredients
Main Ingredients
- 1 lb breakfast sausage cooked and crumbled
- 10 oz fresh spinach wilted and squeezed dry
- 6 slices stale bread cubed
- 1 ½ cups shredded cheddar cheese divided
- 8 large eggs
- 1 ½ cups whole milk
- 1 teaspoon salt
- ½ teaspoon black pepper
- ¼ teaspoon garlic powder
- Butter or cooking spray for greasing the baking dish
Instructions
Preparation
- Grease a 9x13 inch baking dish and layer the cubed bread evenly across the bottom.
- Spread the cooked sausage and wilted spinach over the bread, then top with 1 cup of cheddar cheese.
Assemble
- Whisk together eggs, milk, salt, pepper, and garlic powder in a large bowl until well combined.
- Pour the egg mixture over the layers in the baking dish, ensuring the bread is fully submerged.
- Sprinkle the remaining ½ cup of cheddar cheese over the top, then cover and refrigerate for at least 4 hours, or overnight.
Bake
- The next morning, preheat the oven to 350°F (175°C) and let the casserole sit at room temperature for 15-20 minutes, removing the plastic wrap.
- Bake for 45-60 minutes until set, puffed up, and golden brown; a knife inserted should come out clean.
- Let the casserole rest for 5-10 minutes before slicing and serving.
Notes
For best results, prepare the casserole the night before so the bread can fully absorb the egg mixture. This casserole reheats well for quick breakfasts throughout the week.
