Cook the sausage in a skillet until browned, then remove from heat.

Spray the slow cooker with nonstick spray or use a liner.

Layer half of the tater tots in the bottom of the slow cooker.

Add cooked sausage over the tater tots.

Whisk eggs, milk, half-and-half, cajun seasoning, and half of each cheese in a bowl.

Pour egg mixture over sausage and tater tots. Top with remaining tater tots.

Cover and cook on low for 4 hours or high for 2-3 hours.

Half an hour before done, check for any liquid and cook longer if needed. Add remaining cheese and cook 30 more minutes.

Garnish with chopped parsley and serve hot.
