Crock Pot Chicken Pesto Alfredo Ingredients
- 1 jar pesto (4.58 oz)
- 3 medium boneless skinless chicken breasts
- 1 jar Alfredo sauce (16 oz)
- ½ cup parmesan cheese (more if desired)
- 2 cups noodles, uncooked

How To Make Crock Pot Chicken Pesto Alfredo
- Cut the chicken: Dice chicken into bite-size pieces. Whole breasts can be used, but will require longer cook time.
- Add chicken and pesto: Place the chicken in your crock pot and pour the entire jar of pesto over it. Stir to coat evenly.
- Add Alfredo sauce: Pour in half the Alfredo sauce and stir again until everything is well mixed.
- Cook the chicken: Cover and cook on LOW for 2 hours if using diced chicken, or 5 hours for whole chicken breasts, until tender.
- Cook the noodles: Boil noodles on the stovetop until al dente. Drain and set aside.
- Finish the dish: Add the cooked noodles, remaining Alfredo sauce, and parmesan cheese to the crock pot. Stir well.
- Warm and serve: Cover and cook for an additional 15–20 minutes, then serve hot.

Recipe Tips
- Can I use homemade pesto or Alfredo sauce? Yes, but store-bought versions make this recipe extra easy and consistent.
- What type of noodles work best? Penne, rotini, or fettuccine are great options that hold sauce well.
- Can I add veggies? Yes, stir in spinach, broccoli, or sun-dried tomatoes in the last 30 minutes.
- Is it okay to skip pre-cooking the noodles? Pre-cooking ensures they don’t turn mushy. Avoid adding uncooked noodles directly to the crock pot.
- Can I use frozen chicken? It’s best to thaw chicken first for safe, even cooking in the slow cooker.
