How to Make It
Preheat oven to 450°F. Lightly coat a 13- x 9-inch glass baking dish with cooking spray. Arrange hash brown patties in a single layer in baking dish (trimming patties as needed to fit). Bake in preheated oven until potatoes are golden and cooked through, about 15 minutes. Remove from oven, and set aside. Reduce oven temperature to 350°F.
Heat a large cast-iron skillet over medium-high. Add sausage; cook, stirring occasionally, until crumbled and browned, about 8 minutes. Transfer sausage to a plate lined with paper towels; reserve drippings in skillet.
Add canola oil to drippings in skillet; heat over medium-high. Add onion and bell peppers; cook, stirring occasionally, until softened, about 10 minutes. Sprinkle with 1/2 teaspoon of the salt. Spoon mixture in an even layer over cooked hash browns in baking dish; sprinkle evenly with cooked sausage.
Whisk together eggs, cream, black pepper, and remaining 1 teaspoon salt in a bowl. Pour mixture over sausage (mixture will seep through to bottom of baking dish). Sprinkle evenly with cheese.
Bake at 350°F until eggs are set, about 25 minutes. Remove from oven; sprinkle with scallions and bacon.
