You can prepare the casserole the night before and simply wake up to pop it in the oven = no mess and less stress.
It’s loaded with Everything Bagel Pieces, breakfast sausage, creamy eggs, and cheese- the perfect combo if you ask me, however feel free to customize the filling by adding kale, bell peppers, mushrooms, or any other idea you might have.
First, add the everything bagel pieces to the bottom of your greased 9 x14 casserole dish. Top with cooked sausage and half of the cheese, and then pour the egg mixture on top. Cover with foil and store in the fridge for 4 hours or overnight. Sprinkle with remaining cheese and bake! It’s that easy.
