Before you start
Before you begin, ensure your slow cooker is clean and the ceramic insert is properly seated. Take the chicken breasts out of the refrigerator about 15 minutes before you start to allow them to lose their chill, which promotes more even cooking.
Measure out your Italian seasoning and have your alfredo sauce ready to pour. Clear enough space on your countertop to accommodate the slow cooker, ensuring it is away from any heat-sensitive materials or low-hanging cabinets that might be affected by steam.
Ingredients at a glance (4)
- 1 lb chicken breasts, boneless and skinless
- 16 oz cheese tortellini, refrigerated
- 1 tbsp Italian seasoning
- 15 oz alfredo sauce, store-bought or made ahead
Instructions
Preparation and layering
- Assemble the ingredientsPlace the raw chicken breasts into the base of the slow cooker. Scatter the refrigerated cheese tortellini evenly over the chicken pieces to ensure even distribution during the slow cooking process.Look for Chicken is placed at the bottom.Tip Ensure the tortellini are spread out well.
At the end of this phase, the chicken breasts should be neatly arranged at the bottom of the slow cooker, providing a stable base for the other ingredients. The tortellini should be scattered evenly over the surface, ensuring that they are not clumped together. This layer-by-layer assembly is crucial for success, as it ensures that every piece of pasta is exposed to the sauce and heat, preventing any dry spots or uneven cooking during the slow-simmering process.
Seasoning and saucing
- Season and add sauceEvenly sprinkle the Italian seasoning over the chicken and pasta. Pour the alfredo sauce directly over the top of the ingredients, ensuring everything is well-coated to prevent the pasta from sticking during cooking.Look for Sauce covers the ingredients.Tip Use a spatula to scrape all the sauce from the jar.
Once the seasoning and sauce have been added, the slow cooker should look well-prepared for the cooking phase. The Italian seasoning should be distributed across the top, and the alfredo sauce should be poured evenly, beginning to seep into the crevices between the chicken and tortellini.
There is no need to stir at this stage, as the heat and steam will naturally circulate the sauce throughout the ingredients, ensuring a consistent flavor profile once the cooking cycle is complete.
Slow cooking and resting
- Cook and serveCover the slow cooker and cook on high for 3 hours. Once finished, check that the chicken has reached an internal temperature of 165°F (74°C). Let the chicken rest for 5 minutes before serving to ensure tenderness.Look for Chicken is cooked through and sauce is thickened.Safe temperature 165°F (74°C) internal temperature (poultry)Tip Stir gently before serving to combine the creamy sauce.
After the cooking time has elapsed, the kitchen should be filled with a savory aroma. The chicken will be fully cooked, and the tortellini will have absorbed the sauce, resulting in a creamy, cohesive dish.
Before serving, the chicken should be allowed to rest, which helps redistribute the juices, ensuring each bite remains succulent. The sauce should be thick, silky, and cling perfectly to the tortellini, indicating that the dish is ready for plating and enjoyment.
Common mistakes
A common mistake is overcrowding the slow cooker or using the wrong size, which can lead to uneven cooking. Avoid lifting the lid during the cooking process, as this releases essential heat and moisture, which can significantly increase the total cooking time and potentially lead to undercooked chicken or tough pasta.
Additionally, ensure you do not use frozen chicken breasts directly from the freezer, as this can result in an unsafe temperature gradient; always thaw chicken completely in the refrigerator before use.
How to tell it’s done
To determine if the dish is finished, use a digital meat thermometer to check the thickest part of the chicken breast. The internal temperature must reach at least 165°F (74°C) for safety. The chicken should be tender enough to pull apart with a fork, and the tortellini should be al dente, showing no signs of being overly soft or falling apart. The sauce should appear thickened and glossy, coating the back of a spoon without appearing watery or separated.
- Poultry: 165°F (74°C) in the thickest part
