Overnight Egg-Sausage Bake (6 servings) 1 cup Bisquick or similar baking mix 1 cup shredded Cheddar cheese 2 cups milk 1 teaspoon ground mustard 1/2 teaspoon dried oregano leaves 6 large eggs - slightly beaten 1 pound bulk pork sausage - cooked and drained This is a super easy breakfast casserole. Once you cook and crumble the sausage, it's just a matter of mixing all the ingredients together and waiting until morning... dreaming about the hot breakfast waiting for you. I found it more convenient to put the ingredients in the casserole dish to chill overnight... as opposed to keeping it in a bowl and transferring to a baking dish later. The Sausage Bake you see here cooked for exactly one hour. Overall: Easy and delicious. (This recipe was submitted in 2002. It was tested and photographed in May 2014.) How To Make An Overnight Egg-Sausage Bake Mix all ingredients together in a large bowl. Cover and refrigerate at least 8 hours but no longer than 24 hours. Preheat oven to 350 degrees F. Grease a two-quart casserole dish. Pour egg mixture into the prepared baking dish. Bake uncovered about 1 hour or until knife inserted in center comes out clean. Cooking Notes: You can use any shredded cheese or combination of cheeses. Pepper Jack cheese is especially good. If you like things cheesy, consider increasing the amount of cheese to 1 and 1/2 cups. This is a no-fuss casserole that you prepare the night before for a hassle-free morning. It does require a baking mix like Bisquick. Mr Breakfast would like to thank blackjuice for this recipe.
