Take a 9×13 pan and spray it with non-stick cooking spray. Then cut the biscuits into 1″ pieces and line bottom of pan. Brown the sausage and scatter over biscuits. Sprinkle with cheese.
Whisk eggs, milk and cream together and pour it over the pan contents. Sprinkle with salt, pepper and minced onion.
Make gravy mix per package directions… (yes, cook it all the way to the end, just like you’re going to put it over biscuits) and spoon over the pan contents.
Fry and crumble your bacon and keep it overnight, as well.
The next morning, preheat your oven to 350 degrees. Pop the casserole in straight from the fridge, uncovered. Cook for one hour and 5 minutes; or until golden brown.
