Easy Breakfast Sausage Casserole Recipe

Ingredients:

For the Casserole:

Instructions:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray or butter to prevent sticking.
2. Cook the Sausage: In a large skillet over medium heat, cook the breakfast sausage until it’s browned and fully cooked, breaking it up with a spatula as it cooks. If you are using it, add the chopped onion and cook until it softens, about 3-4 minutes, stirring with the sausage. Drain any excess grease from the skillet and set the cooked sausage mixture aside.
3. Prepare the Egg Mixture: In a large mixing bowl, whisk together the 6 large eggs, 2 cups whole milk (or half and half), 1 teaspoon salt, 1/2 teaspoon black pepper, and the optional 1 teaspoon ground mustard until all ingredients are well combined and the mixture is frothy.
4. Assemble the Casserole:
   • Layer the cubed bread evenly in the bottom of the prepared 9×13-inch baking dish.
   • Top the bread with the cooked sausage mixture, distributing it evenly over the bread.
   • Sprinkle 1 1/2 cups of shredded cheddar cheese (or your preferred cheese blend) over the sausage and bread layers.
   • Carefully pour the prepared egg mixture evenly over the bread, sausage, and cheese in the baking dish. Gently press down on the mixture with the back of a spoon or spatula to ensure the bread soaks up the egg mixture.
   • Sprinkle the remaining 1/2 cup of shredded cheese on top of the casserole.
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, you can insert a knife into the center—if it comes out clean, the casserole is ready.
6. Garnish and Serve: Remove the casserole from the oven and let it cool for about 5 minutes before slicing. If desired, garnish with freshly chopped parsley for a pop of color and freshness. Serve warm and enjoy!
