Servings
- 6–8 servings
Ingredients
For the Casserole:
- 1 lb breakfast sausage (mild or spicy, depending on preference)
- 1 medium onion , chopped (optional)
- 6 large eggs
- 2 cups whole milk (or half-and-half for a richer casserole)
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon ground mustard (optional, adds depth of flavor)
- 6 slices of bread , cubed (day-old bread works best)
- 2 cups shredded cheddar cheese (or a combination of cheddar and mozzarella)
- 2 tablespoons fresh parsley , chopped (for garnish, optional)
Instructions
Step 1: Preheat the Oven
- Preheat your oven to 350°F (175°C) .
- Grease a 9×13-inch baking dish with cooking spray or butter. Set aside.
Step 2: Cook the Sausage
- In a large skillet over medium heat , cook the breakfast sausage , breaking it into small crumbles with a spatula, until browned and fully cooked.
- If using, add the chopped onion to the skillet and cook until softened, about 3–4 minutes .
- Drain any excess grease and set the cooked sausage mixture aside.
Step 3: Prepare the Egg Mixture
- In a large mixing bowl, whisk together the eggs , milk , salt , pepper , and ground mustard (if using) until well combined.
Step 4: Assemble the Casserole
- Layer the cubed bread evenly in the bottom of the prepared baking dish.
- Top the bread with the cooked sausage mixture , spreading it out evenly.
- Sprinkle 1½ cups of shredded cheese over the sausage and bread.
- Pour the egg mixture evenly over the bread, sausage, and cheese. Use a spatula or the back of a spoon to gently press down, ensuring the bread soaks up the egg mixture.
- Sprinkle the remaining ½ cup of shredded cheese on top for a gooey, golden finish.
Step 5: Bake the Casserole
- Place the baking dish in the preheated oven and bake for 40–45 minutes , or until the top is golden brown and the casserole is set in the center.
- To check for doneness, insert a knife into the center—if it comes out clean, the casserole is ready.
Step 6: Garnish and Serve
- Remove the casserole from the oven and let it cool for 5 minutes before slicing.
- Garnish with freshly chopped parsley for a pop of color, if desired.
- Serve warm and enjoy as a standalone dish or pair with fresh fruit, toast, or a side salad for a complete meal.
Pro Tips
- Make Ahead: Assemble the casserole the night before, cover tightly, and refrigerate. Bake as directed, adding an extra 5–10 minutes if needed.
