Keto Slow Cooker Breakfast Casserole
A hearty breakfast casserole that combines savory breakfast sausage, ham, and cheddar cheese with cauliflower rice instead of traditional bread or potatoes. The slow cooker method makes this perfect for meal prep or feeding a crowd without morning fuss. Eggs and cream create a rich, custard-like base that sets beautifully during the long, gentle cooking process. The addition of red pepper and garlic adds depth while red pepper flakes provide a subtle kick.

Cook sausage links ahead of time and slice when cool for easier handling and better distribution throughout the casserole.
Use fresh cauliflower rice for better texture, but frozen works well if thawed and drained of excess moisture first.
Good to Know
Refrigerate leftovers for up to 4 days in covered container. Reheat individual portions in microwave.
Assemble completely the night before, cover and refrigerate. Add 30-60 minutes to cooking time if starting cold.
Cut into squares and serve hot. Pairs well with fresh fruit or toast.

FAQ
Can I make this with regular rice instead of cauliflower rice?
Yes, but use cooked rice and reduce the liquid slightly as regular rice absorbs less moisture than cauliflower rice during cooking.
How do I know when the casserole is fully set?
The edges should be lightly browned and the center should be firm to touch, not jiggly. A knife inserted in center should come out clean.
Can I freeze portions of this casserole?
Yes, freeze individual portions for up to 3 months. Thaw overnight in refrigerator and reheat in microwave or oven until heated through.
