Spray crock well with cooking spray. In a mixing bowl, whip egg and milk together. Stir in spices.
Add cheese and noodles, and stir well to combine. Pour the mixture into the crock pot.
It will be very liquidy.
Cover and cook on low for 2-5 hours, or on high for 1-3. The cooking time will vary depending on what size crockpot you are using, and how quickly it heats and cooks. I was quite surprised at how quickly our pasta got fork-tender.
