Preheat the oven to 425 degrees. Spray a pie pan with cooking spray.
Line the bottom of the pan with tater tot crowns or mini hash browns. Then line the sides with the potatoes as well.
Bake for 15 minutes then remove from oven.
Using a spoon press the hot hash browns down so that they fuse together and form a crust on the bottom and sides of the pan. Set aside.
Heat the oil in a sauté pan over medium heat. Whisk together the eggs and sprinkle with salt, pepper, and garlic. Pour into the pan and cook until they are just set. I gave them a turn or two to help them along. Remove from heat.
Sprinkle the hash brown crust with 1 cup of the cheese.
Carefully scoop the eggs out of the pan and lay on top of the cheese. Sprinkle the top of the eggs with the sausage and then with the other cup of cheese.
Top the casserole with the asparagus.
Place in the oven and bake for 15 minutes. Remove from oven and let sit for 5minutes then cut into pieces and enjoy.
