This is a very popular breakfast casserole at our family get-togethers. Obviously, you can make substitutions. If you don’t like sausage, you can substitute ham, Italian sausage, bacon or whatever. If you don’t want cream of mushroom soup, use cream of celery, cream of onion, or whatever cream soup you like. I make my own soup for this because of my food allergies. However, if you would like to use canned soup, use 1 can of soup and 1 can of milk.
Butter a 9x13" baking dish.
Cook onion with sausage in skillet, crumbling as it cooks.
Beat eggs, heavy cream, milk, sour cream and seasonings. Add cooked sausage and onions to mixture. Pour into prepared baking dish.
Top with green chilies and some cheese.
Top with tater tots and remaining cheese.
Cover and refrigerate overnight. (This can be made just before baking, but the tater tots should be thawed.)
In the morning, preheat oven to 375 and remove pan from fridge. Bake 50-60 minutes or until golden.
This can be served with salsa and sour cream or green or red chilie.
