Before you start

Before you begin, ensure your slow cooker insert is properly seated. Take the turkey tenderloins out of the refrigerator about 20 minutes before cooking to allow them to lose their immediate chill.

Gather all your measuring tools and prepare the onions by slicing them into thin, uniform strips. Having your ingredients prepped and ready to assemble will make the process smooth and quick.

Ingredients at a glance (6)
  • 2 lb turkey breast tenderloins
  • 1 cup sliced onions
  • 1 tsp cracked black peppercorns
  • 1/2 tsp garlic powder
  • 1 can (10.5 oz) condensed cream of chicken soup
  • 1/2 cup chicken broth

Instructions

Arranging the turkey

  1. Prepare the slow cooker
    Place the turkey tenderloins into the ceramic insert of your slow cooker. Distribute the sliced onions evenly over the top of the turkey pieces.
    Look for The turkey should be arranged in a single layer at the bottom of the cooker.
    Tip Ensure the onions are scattered well to infuse the meat with flavor during the cooking process.

The turkey should be placed in the bottom of the slow cooker insert, with the onions spread evenly over the top. The onions act as a bed for the meat, helping to keep the bottom of the turkey from scorching and ensuring a consistent distribution of flavor as they soften during the initial stages of the slow cooking process.

Adding the sauce

  1. Season and sauce
    In a small bowl, whisk together the condensed cream of chicken soup and chicken broth until smooth. Sprinkle the cracked black pepper and garlic powder over the turkey, then pour the cream mixture over the top.
    Look for The sauce should be thick and well-combined before pouring.
    Tip Whisking the soup and broth separately ensures no lumps remain in the final sauce.

Once the cream of chicken soup, broth, and seasonings are added, ensure everything is well-distributed. The mixture should look like a smooth, thick liquid coating the onions and turkey.

This phase is critical because proper coverage ensures that the turkey tenderloins will braise uniformly in the flavorful liquid throughout the duration of the cooking cycle.

Final cooking and resting

  1. Cook and serve
    Cover and cook on low for 4 hours until the turkey is cooked through. Ensure the internal temperature reaches 165°F (74°C) using a meat thermometer. Let the turkey rest for 5 minutes before slicing and serving with the warm sauce.
    Look for The turkey should be opaque throughout and the sauce creamy and bubbling.
    Safe temperature 165°F (74°C) internal temperature (poultry)
    Tip Resting the meat is essential to keep the tenderloin juicy before slicing.

At the end of the cooking time, the turkey should look tender and soft, with a creamy, light-colored sauce surrounding it. The onions should be translucent and very soft. Check the internal temperature to ensure it has reached 165°F (74°C). Let the turkey rest for 5 minutes before slicing so the juices redistribute, ensuring every bite is moist and tender.

Common mistakes

A common mistake is overcrowding the slow cooker or using pieces of turkey that are vastly different in size, which causes uneven cooking. Ensure the tenderloins are similar in thickness so they finish at the same time.

Also, avoid lifting the lid frequently during the cooking process; every time the lid is opened, heat escapes, which significantly increases the time needed for the internal temperature to reach the safe zone.

How to tell it’s done

The turkey is done when it is completely opaque throughout and the internal temperature reaches 165°F (74°C). The surface should look soft and braised, with the sauce appearing thick, creamy, and clinging to the meat.

Use a digital meat thermometer inserted into the thickest part of the tenderloin to confirm it has reached the safe temperature before removing it from the cooker to rest.

  • Poultry: 165°F (74°C) in the thickest part
