1

Gather all the ingredients.
2

Coat a 9x13 baking dish with cooking spray. Spread the hash browns in the prepared dish.
3

Cook the sausage in a large skillet over medium heat until it begins to brown, about 2 minutes.
4

Add the bell peppers, onion, garlic, and oregano to the skillet. Continue to cook until the vegetables are tender and the sausage is no longer pink, about 5 minutes. Add the spinach and cook until wilted, about 1 minute.
5

Distribute the vegetable and sausage mixture over the hash browns in the baking dish. Sprinkle the cheese over the top.
6

Whisk the eggs, milk, mustard, salt, and pepper together in a bowl. Pour the egg mixture over the casserole. Cover and refrigerate for 8 hours to overnight.
7

Preheat the oven to 325 degrees F (165 degrees C).
8

Bake the casserole, uncovered, in the preheated oven until a knife inserted in the center comes out clean, 50 to 60 minutes. Let stand for 10 minutes before serving.
