Sage Garlic Butter Slow Cooker Turkey Breast

Prepping the turkey breast

1. Pat dry the turkey breast. Then using your fingers - loosen the skin on the turkey breast without detaching it (so that it's just loose enough to sprinkle salt and rub butter under the skin).
2. Sprinkle salt under the skin, making sure to cover the whole turkey breast. Keep the turkey breast in an airtight container (or wrapped with plastic wrap on a plate), in the fridge for up to 2 days (or at least overnight) to marinate.

Sage garlic butter paste

1. Place all the ingredients (except for the butter), in a food processor, and process to form a spice paste.
2. Alternatively, you can finely chop each ingredient individually, and also use cracked black pepper instead. OR you can use a mortar and pestle to make the paste.
3. Place the spice mix in a bowl with the softened butter, and mix to combine.

Cooking the turkey breast

1. Remove the seasoned / marinated turkey breast from the fridge and pat dry with paper towels.
2. Rub the sage garlic butter paste all over the turkey breast. Make sure to be generous with the butter under the skin as well. Allow the turkey to come to room temperature, about 30 - 40 minutes (depends on the size of the turkey breast).
3. Place the onion halves on the bottom of your slow cooker, cut sides down. Place the garlic butter rubbed turkey breast on top of the onion halves, so that it's elevated from the bottom of the pan. I use the slow cooker function in my Instant Pot, so it looks different from other slow cookers. Add the stock, and a little salt to the bottom of the pot as well.
4. Close the slow cooker and set it to LOW. Cook for about 5 - 7 hours, covered. Use the meat thermometer to check the internal temperature to make sure you don’t exceed 160°F - 162°F (it takes me about 5.5 hours for this cut of turkey).
5. Remove the turkey breast and place it on a plate with about ¼ cup of the pan drippings. Cover with foil and let it rest for at least 30 minutes.
6. Remove the onions from the pot and strain the pan drippings into a small bowl.

Before serving

1. Preheat the broiler in your oven. Place the slow cooked turkey breast on the broiler pan, and brush the surface of the turkey roast with some of the pan drippings, OR a little extra butter.
2. Broil for a few minutes until the skin caramelizes. Keep the broiler door open and keep an eye on the roast to make sure the skin doesn't burn.
3. Serve, along with some of the pan drippings (or gravy), and other side dishes.
