How to Make It
Bring broth to a boil in a large saucepan over medium-high. Gradually whisk in grits, and cook 8 to 10 minutes.
Remove from heat, and whisk in milk, cream, and butter. Whisk in salt, peppers, and breadcrumbs. Lightly grease a 6-quart slow cooker with cooking spray. Place grits mixture in slow cooker.
Cover and cook on HIGH 4 hours. Remove lid; whisk grits until smooth, and top with cheese. Cook, uncovered, for 30 minutes.
