Helpful Tips
- For the best texture, ensure your frozen hash browns are fully thawed and patted dry with paper towels to prevent excess moisture.
- If you want a crispy top, you can carefully transfer the slow cooker insert to the oven and broil it for 2 to 3 minutes at the very end, provided your insert is oven-safe.
- To make this vegetarian, substitute the sausage with a mix of sauteed mushrooms, spinach, and black beans.
- For a spicy kick, add diced jalapenos or a pinch of cayenne pepper to the egg mixture, and serve with hot sauce.

Step-by-Step Instructions
- In a large skillet over medium-high heat, cook the ground sausage and diced onion until the sausage is browned and fully cooked, crumbling it as it cooks. Drain excess grease.
- Grease the inside of a 6-quart slow cooker generously with non-stick cooking spray.
- Spread half of the thawed hash browns into the bottom of the slow cooker, followed by half of the cooked sausage and onion mixture, and half of the diced red bell peppers.
- Sprinkle half of the Cheddar and Monterey Jack cheeses over the layer.
- Repeat the layers with the remaining hash browns, sausage mixture, red bell peppers, and half of the remaining cheese.
- In a large bowl, whisk together the eggs, whole milk, salt, black pepper, garlic powder, and paprika until smooth and well combined.
- Pour the egg mixture evenly over the layered ingredients in the slow cooker.
- Cover and cook on LOW for 6 to 8 hours, or on HIGH for 3 to 4 hours, until the eggs are set and a knife inserted in the center comes out clean.
- During the last 15 minutes of cooking, sprinkle the remaining cheese on top, cover, and let it melt.
- Garnish with fresh chopped chives before slicing and serving hot.
