1-Step 1: Set Up Your Slow Cooker
Line a 6-quart slow cooker with a slow cooker liner and place the two onion halves at the bottom to act as a natural rack. This setup helps prevent burning and adds extra flavor to the roast.

2-Step 2: Prepare the Turkey
Remove the turkey roast from its packaging and keep the gravy packet aside. Place the turkey roast fat cap side up inside the liner for better self-basting during cooking. Season it with black pepper to enhance the natural flavors.

3-Step 3: Add Liquids and Seasonings
Pour the contents of the gravy packet, chicken broth, and white cooking wine (or your substitute) into the liner. In a small bowl, mix the garlic powder, onion powder, paprika, thyme, sage, poultry seasoning, and salt, then rub this blend gently over the turkey roast for even seasoning.

4-Step 4: Top and Cook
Lay the two orange slices on top of the roast, along with the rosemary, thyme, and sage sprigs for a fresh herbal note. Seal the liner by folding the edges 2 to 3 times and securing with a metal clip, then cover with the slow cooker lid. Cook on low for 4 hours or until the internal temperature reaches 165°F.

5-Step 5: Finish and Serve
Carefully open the bag and reserve the juices for gravy. Remove the roast, discard the orange slices, herbs, and netting, then let it rest before slicing. This recipe takes just 10 minutes to prepare and 4 hours to cook, totaling 4 hours and 10 minutes, making it ideal for busy schedules.
