Instructions

- Layer the Hash Browns: Add a generous layer of hash browns at the bottom of your slow cooker. They should cover the base evenly, creating a nice foundation for your casserole.
- Add the Sausage: Sprinkle in your cooked turkey sausage over the hash browns. Ensure the sausage is well-cooked and crumbled for even distribution.
- Mix the Eggs: In a medium bowl, whisk together the eggs with a splash of your chosen milk and the seasonings until you achieve a light scramble look.
- Layer in Vegetables: Pour the egg mixture over the sausage and sprinkle in the bell peppers or other vegetables you like.
- Top with Cheese: Sprinkle your shredded cheddar cheese generously over the top of the mixture.
- Set the Cooker: Cover your slow cooker with its lid and set it on low to cook overnight for approximately 8 to 9 hours.
- Serve and Enjoy: Once fully cooked, serve it warm after letting it cool a bit to hold together better. Enjoy it with a sprinkle of fresh herbs or a dollop of salsa.

Recipe Tips
- If the casserole is too dry on top, adding a little extra milk or cheese just before serving can help moisten it.
- When the bottom layer seems soggy, remember to place the hash browns at the bottom and follow the cooking time carefully.
- If the eggs aren’t fully set in the center, consider extending the cooking time by about 15-20 minutes, especially with thawed ingredients.
- For easier prep, chopping the vegetables and cooking the sausage earlier in the day can save you some time in the morning.
- When layering ingredients in the crock pot, doing it in the right order helps with even cooking and overall texture.
