Mix all ingredients together. Place in an air tight container or zip lock bag until ready to use.
For the turkey:
In the bottom of your crock pot, place the vegetables, garlic and bay leaves.
For the turkey, take 2 tsps of the cajun seasoning blend and rub it all over the outside and under the skin. Place this on top of the vegetables in the slow cooker.
Let this cook on low for 4-6 hours or high 3-5 hours. Make sure to check the inside temperature using a thermometer, you want it to read at least 165 degrees.
Take the turkey out the crock pot and remove the meat section by cutting down alone the breast bone. Cut into slices and serve with your desired sides!
If you want to make a gravy, you can thicken the drippings that accumulated in the bottom of the crock put with a cornstarch slurry mixture, after taking out the bay leaves and vegetables.
