I am sharing our family’s easy egg and sausage casserole recipe. My egg and sausage casserole recipe is incredibly simple and easy to make and is prepared the night before so there is little more to do but put it in the oven for breakfast the next morning.
I make it for breakfast every Thanksgiving, Christmas and Easter morning because it’s our family’s favorite.
It does take 1 1/2 hours to bake so make sure you give yourself enough time.
Growing up my mom would put the egg and sausage casserole recipe in the oven as soon as we woke Christmas morning.
That way breakfast was ready just as we were finishing up opening our presents!
