Before you start
Before beginning the cooking process, ensure that the slow cooker insert is clean and dry. Remove the turkey breast from its packaging and pat it dry with paper towels to ensure it is ready to receive the rub. Slice the yellow onion into uniform rounds approximately 1/4-inch thick.
Prepare the sauce mixture by combining the cherry cola and ketchup in a pitcher, stirring well to incorporate the ingredients. Have a reliable meat thermometer ready, as this is essential for verifying that the turkey reaches the safe internal temperature required for food safety.

- 2 lb turkey breast roast
- 1 large yellow onion, sliced into rounds
- 1/4 cup brown sugar
- 1 cup cherry cola
- 1/2 cup ketchup
Instructions
Layering the Base
- Prepare the Slow CookerPlace the turkey breast into the slow cooker basin. Arrange the sliced onion rounds around the turkey to create a flavorful bed. Ensure the turkey is positioned centrally to allow for even heat distribution during the cooking process.Look for The turkey should sit flat in the bottom of the insert.Tip Ensure the onions are sliced uniformly to cook at the same rate.
At the end of this phase, the turkey should be resting on a stable bed of onions within the slow cooker. The ingredients should be arranged to promote even heat circulation.
Check that the onions are evenly distributed to provide a consistent base that will prevent the turkey from direct contact with the base of the insert, ensuring a gentle cooking environment from the start.
Adding the Glaze
- Add Seasonings and SauceSprinkle the brown sugar evenly over the top of the turkey breast. In a separate small pitcher, mix the cherry cola and ketchup together until well combined. Pour this mixture over the turkey and the surrounding onions, ensuring the sugar and sauce coat the meat thoroughly.Look for The liquid should partially pool around the base of the turkey.Tip Whisking the ketchup and cola before pouring helps create a more uniform glaze.
The turkey should be thoroughly coated with the brown sugar and the cherry cola-ketchup mixture. The liquid should be visible around the base of the turkey, creating a shallow braising environment. Confirm that the brown sugar has been evenly distributed over the surface of the meat to encourage proper caramelization and flavor development as the sauce heats up.
Slow Cooking
- Cook and ServeCover the slow cooker and cook on low for 4 to 6 hours. Once the turkey reaches an internal temperature of 165°F (74°C), remove it from the slow cooker. Allow the meat to rest for at least 10 minutes before slicing and serving with the cooked onions and pan sauce.Look for The meat should be opaque and tender throughout.Safe temperature 165°F (74°C) internal temperature (poultry)Tip Use a meat thermometer to ensure the turkey is safely cooked.
The turkey is ready when it is completely opaque and has reached 165°F (74°C). The onions should be soft and translucent, and the sauce should have thickened into a rich, flavorful glaze. Verify the temperature with a thermometer before removing the turkey, and ensure it rests for 10 minutes before slicing to maintain the moisture and overall quality of the dish.
Common mistakes
A common mistake is failing to allow the meat to rest after cooking, which can lead to moisture loss and dry slices. Another error is neglecting to check the internal temperature, which can result in undercooked poultry.
Additionally, avoid using diet sodas, as the lack of sugar prevents the sauce from thickening properly into a glaze. Finally, do not lift the lid during the last hour of cooking, as this releases heat and steam, which are vital for maintaining the internal environment of the slow cooker and ensuring the turkey cooks evenly.
How to tell it’s done
The turkey is considered done when it reaches a safe internal temperature of 165°F (74°C). Use a meat thermometer inserted into the thickest part of the breast to confirm this. The meat should be opaque white throughout with no traces of pink, and the juices should run clear.
The texture should be fork-tender and easily sliceable. Allowing the turkey to rest for at least 10 minutes after removing it from the slow cooker is crucial, as this permits the juices to redistribute, ensuring the meat remains succulent and flavorful when served.
- Poultry: 165°F (74°C) in the thickest part
