Step 1

Combine chicken stock, salt, rosemary, thyme, savory, and sage in a bowl.

Step 2

Place turkey in the brining bag and fill with brine, making sure to fill the cavity. Transfer the bag to a 5-gallon pot filled with water. Slowly push the brining bag under the water while you seal it, squeezing air out as you go; remove as much air as possible so bag does not float.

Step 3

Attach a sous vide cooker to the edge of the pot. Wrap it in a dish towel for insulation. Cover the pot with plastic wrap to reduce evaporation. Set temperature to 150 degrees F (65 degrees C); cook for 18 to 24 hours.

Step 4

Preheat the oven to 375 degrees F (190 degrees C).

Step 5

Remove turkey from the brining bag and transfer to a large roasting pan. Discard brine.

Step 6

Bake in the preheated oven until nicely browned, about 30 minutes. An instant-read thermometer inserted into the thickest part of the thigh, near the bone, should read 165 degrees F (74 degrees C). Remove from the oven, cover with a doubled sheet of aluminum foil, and allow to rest in a warm area for 10 minutes before slicing.
