How to Make Slow Cooker Cheesy Hashbrown Casserole

Lightly grease a 5- to 6-quart slow cooker with nonstick cooking spray or butter to prevent sticking.

Season with salt and black pepper, then gently stir until everything is evenly coated.
Step 3: Slow Cook
Cover and cook:

Stir once or twice during cooking if convenient to help distribute the melted cheese evenly.

Tips for the Best Hashbrown Casserole

- Use freshly shredded sharp cheddar for the best melt and flavor.
- Avoid lifting the lid too often while cooking.

Frequently Asked Questions
Can I cook this casserole on HIGH?
