Preheat your oven to 375°F (190°C). Grease a 9x13-inch casserole dish with butter or cooking spray.
In a large skillet over medium heat, cook the breakfast sausage, breaking it into crumbles, until fully browned. Drain any excess grease and set aside.
In the same skillet, sauté the chopped onion and bell pepper for 3-4 minutes until softened. Remove from heat.
Spread the frozen hash browns evenly across the bottom of the greased casserole dish.
Sprinkle the cooked sausage over the hash browns, followed by the sautéed onion and bell pepper.
In a large mixing bowl, whisk together the eggs, milk, salt, and black pepper until well combined.
Pour the egg mixture evenly over the casserole filling, ensuring it seeps into the layers.
Top with the shredded cheddar cheese, spreading it evenly across the casserole.
Bake in the preheated oven for 35-40 minutes, or until the eggs are fully set, the top is golden, and a knife inserted into the center comes out clean.
Let the casserole rest for 5 minutes before slicing into portions. Serve warm and enjoy!
