Butter or nonstick cooking spray

1 lb.

breakfast sausage, such as Jimmy Dean



red bell pepper, chopped


green onions, chopped, white and green parts divided



1 1/4 c.

heavy cream 

1 tbsp.

dijon mustard

2 tsp.

hot sauce (optional)

1 1/2 tsp.


1 tsp.

black pepper

2 c.

shredded sharp cheddar cheese, divided


(30-oz.) package of frozen, shredded hash browns, thawed 

Step  1 Preheat the oven to 350°F. Grease a 13-by-9-inch (or other 3-quart) baking dish with butter or nonstick cooking spray. Step  2 Heat a large skillet over medium-high heat. Add the sausage, breaking it up into small pieces with a wooden spoon. Cook the meat until no pink pieces remain, 6 to 8 minutes.

Step  4 Cover with aluminum foil and bake for 50 minutes. Remove the foil and top with the remaining 1/2 cup of cheese. Increase the oven temperature to 400°F and finish baking until the center of the casserole is set (not jiggly) and the top is slightly golden, 10 to 15 minutes more. Let rest for 10 minutes, top with the remaining green parts of the green onion, and serve.
