Begin by preheating your oven to 375°F and greasing a large casserole dish with non-stick spray.

Cook the bacon until it's crispy, then chop it roughly and set it aside, letting the savory smell waft through your kitchen.

In a large mixing bowl, combine the hashbrowns, chopped bacon, sausage crumbles, diced bell pepper, and 2 cups of cheddar cheese. Toss well, ensuring that the hashbrowns are not clumped together, and then pour the mixture into the prepared casserole dish.

In another bowl, whisk together the eggs, half & half, Worcestershire sauce, ground mustard, salt, and pepper until the mixture becomes light and fluffy. Pour this over the hashbrown mixture, allowing it to soak in, and finish with the remaining grated cheese on top.

Bake the casserole in your preheated oven for 40-45 minutes, until the cheese is golden brown and the center is set. Let it cool for about 5 minutes before topping with finely chopped green onions and serving.
