Before you start
Before starting, ensure your slow cooker insert is clean and dry. Prepare the turkey by trimming any excess fat and cutting it into uniform, bite-size cubes. Measure out the alfredo sauce and chicken broth, keeping them in a separate container for easy mixing.
Ensure the mushrooms are cleaned and sliced evenly. Having all ingredients prepared and measured before you begin assembling the base will make the process smooth and efficient, allowing for a quick setup before the slow cooker takes over the cooking process for the next few hours.
Ingredients at a glance (7)
- 1 lb turkey tenderloin, cut into bite-size cubes
- 8 oz mushrooms, sliced
- 1 cup frozen peas
- 1 tsp Italian seasoning
- 1/2 tsp garlic powder
- 15 oz alfredo sauce
- 1/2 cup chicken broth
Instructions
Preparation and assembly
- Assemble the basePlace the cubed turkey tenderloin into the slow cooker ceramic insert. Scatter the sliced mushrooms and the frozen peas over the turkey. Sprinkle the Italian seasoning and garlic powder evenly across the ingredients.Look for The turkey should be spread out in a single layer at the bottom of the slow cooker insert to ensure even cooking.Tip Ensure the turkey pieces are cut into uniform sizes so they cook at the same rate.
At this stage, the slow cooker contains a layered arrangement of turkey, mushrooms, and peas, topped with the Italian seasoning and garlic powder. The ingredients are raw, but they are positioned correctly to allow for even heat distribution. Ensure that the ingredients are not packed too tightly into the insert, allowing the sauce to circulate effectively once added during the next phase.
Slow cooking cycle
- Add liquids and cookWhisk the alfredo sauce with the chicken broth in a small bowl until smooth. Pour this mixture over the turkey and vegetable combination. Cover the slow cooker and set to low, cooking for approximately four hours until the turkey reaches 165°F (74°C).Look for The sauce should completely coat the turkey and vegetables, creating a uniform mixture before the lid is placed on the slow cooker.Safe temperature 165°F (74°C) internal temperature (poultry)Tip Do not lift the lid during the first few hours of cooking to maintain a consistent internal temperature.
During the cooking phase, the liquids are combined and added to the slow cooker. The mixture should look uniform and well-incorporated. After several hours, the soup will begin to emit a rich, savory aroma. The turkey will be cooking in the alfredo base, which will thicken as the flavors meld. Ensure the lid remains tightly sealed throughout this period to maintain a consistent temperature for safe cooking.
Final rest and serving
- Rest and serveOnce the turkey reaches the internal temperature of 165°F (74°C), turn off the slow cooker. Allow the soup to rest for at least 3 minutes, or up to five minutes, which helps the creamy sauce thicken slightly and settle before serving in shallow bowls.Look for The soup will appear thick and creamy with the turkey tender and opaque throughout.Tip Stir the soup gently before serving to ensure all the creamy elements are well combined.
The final stage involves turning off the slow cooker and allowing the soup to rest. The soup should be thick, creamy, and fragrant. The turkey should be perfectly cooked through, and the vegetables should be tender.
Check that the sauce has achieved the desired consistency before serving. A quick stir ensures that any separated fats are re-incorporated into the creamy base, resulting in a smooth, velvety texture for each bowl served.
Common mistakes
A common mistake is overcrowding the slow cooker, which can prevent the ingredients from cooking evenly. Always ensure the turkey is spread out in an even layer. Another oversight is using a sauce that is too thin or lacks enough seasoning; taste the mixture once it has warmed through and adjust with salt or pepper if necessary.
Finally, avoid lifting the lid repeatedly, as each time the lid is opened, heat escapes, extending the total cooking time and potentially affecting the final texture of the turkey and vegetables.
How to tell it’s done
The soup is ready when the turkey pieces are completely opaque and tender throughout. Use a kitchen thermometer to verify that the internal temperature of the turkey has reached 165°F (74°C).
The sauce should be thickened and creamy, coating the back of a spoon, and the vegetables should be tender but still hold their shape. If the soup appears too thin, remove the lid for the last thirty minutes of cooking to allow some of the liquid to evaporate and the sauce to reduce slightly.
- Poultry: 165°F (74°C) in the thickest part
- Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
