Turkey Breast cooked in a slow cooker is super easy and convenient especially for me! I live with my family and my sis and I take turns cooking dinner but let's face it, sometimes you just get sick of being on your feet using recipes that dirty up a gazillion pots, pans, and mixing bowls. (*also our regular oven is broken so we either use the stovetop, slow cooker or toaster oven)
Thaw out turkey breast in refrigerator for AT LEAST a day. (I looked online and it was supposed to be a day for a 5 pound turkey breast but when I took it out the next day and unwrapped it, it was still slightly icy b/c of the gravy packet that was crammed in the cavity of the turkey breast sooooo a day and a half might be better. Don't fret if it is still frozen! You can also thaw in cold water. I just ended up running water over it and by the time I was done playing with it, it wasn't frozen anymore. Sorry for the paragraph lol!
Remove any excess skin hanging from the end of your turkey breast. Oil up a 6 quart slow cooker (just depends on size of turkey breast) with olive oil or cooking spray. Slice the onions and lay on bottom of slow cooker so that your turkey breast can rest on top of them and doesn't feel so alone. :)
Rub your turkey breast with some olive oil if you like. That's what I did but I think it would have been fine without it. Mix your seasonings together and sprinkle all over your turkey breast (try to get it under the skin too). *NOTE: My turkey breast had been injected with a salt solution so I didn't add salt but some more wouldn't have hurt it so that's why I added a tsp to the ingredient list.
Ok. So your turkey has been rubbed and seasoned and hugged...well, not the last one. Now place it on top of the onions. I had to place mine on its side because I guess it was too tall for the cooker so one side did end up flatter but it didn't change the yumminess! Put lid on, set your slow cooker on low and let that baby cook for 6 hours. My slow cooker instructions said 6-7 hours for a 6-7 pound turkey breast. Mine was b/t 5 and 6 so I went with 6 hours and it wasn't overcooked. Obviously you know how your slow cooker works better than I do so times may vary. *Now, I've read online that some take out the turkey breast when it is done and put it under the broiler in their oven for a bit to crisp up the skin but my oven is broken so I just removed the skin when I cut it up.
Enjoy! I chucked the gravy packet that came with it and made my own using a beef gravy recipe I found online but substituting the beef broth with chicken broth but whatever works for you. Serve with stuffing and cranberry sauce.
