In a skillet over medium heat, cook the crumbled breakfast sausage until browned. Drain excess fat and transfer the sausage to the crock pot.
Add the diced onion and bell pepper to the crock pot with the sausage.
In a large bowl, whisk together the eggs, milk, salt, black pepper, garlic powder, and paprika until well combined.
Layer the frozen hash browns over the sausage and vegetables in the crock pot.
Pour the egg mixture evenly over the hash browns.
Sprinkle the shredded cheddar cheese on top.
Cover the crock pot and cook on low for 6-8 hours or on high for 3-4 hours, until the eggs are set and the cheese is melted.
Once cooked, gently stir to combine before serving.
