  1. Add pasta, 5 cups chicken broth and chicken breasts to Instant Pot.
  2. Make sure that all pasta is covered with chicken broth.
  3. Cook on MANUAL for 6 minutes, then allow for a natural pressure release for 6 minutes before moving the valve over to VENTING.
  4. Remove lid and then remove chicken from Instant pot and shred with two forks.
  5. Add in the shredded chicken, jar of diced tomatoes, jar of alfredo sauce, and jar of pesto.
  6. Turn the Instant Pot to SAUTE and cook until sauce is bubbly.
  7. Turn off the Instant Pot and serve, topping with your favorite garnishes.

  2. Karen Hilliard says:

    This looks so delicious, I’m definetly going to be making this this week!!!

  3. Nicole says:

    Hi! Can you tell me approximately how much is in one serving!

  4. Cyd says:

    The servings for this recipe can totally vary depending on how large of a serving someone takes. With a 16 ounce package of pasta and 5 chicken breasts, it will easily feed 8 people with generous size portions.

  5. Tayna says:

    Do you have a favorite alfredo pasta sauce?

  6. Cyd says:

    We often buy whatever is on sale. But Bertolli is pretty good.

  7. Dani Eaton says:

    Would it work if I cut this recipe half?

  8. Cyd says:

    It should work fine. Be sure to check often in case it needs less cooking time.

  9. Brenda says:

    Can I cook the pasta in the crockpot with the chicken and other ingredients?

  10. Cyd says:

    I'm sure you could. We have not made this recipe adding the pasta to the slow cooker. So we can't give you exact directions.

  11. Karlee Thomsen says:

    Does 497 kcal mean that this meal is 62,125 calories per serving?

  12. Momma Cyd says:

    No, it means that it's 497 calories per serving.

  13. Brandi K says:

    This wasn’t a good as I was hoping it would be. Pretty bland, we had to add extra cheese on top to add some falvor. We liked it, but don’t think I will make it again.

  14. Mary K says:

    Making this tonight, the description of the recipe calls for one can of diced tomatoes, along with the picture of all the ingredients… but the printable recipe calls for 2 cans. Do you use one or two cans for this recipe? Thanks.

  15. Momma Cyd says:

    Either will work just fine. We have done it with both.

  16. Ashley says:

    How would you convert this recipe to IP?

  17. MARLO ANN says:

  18. Wife of a Nerd says:

    It turned out runny not creamy which was disappointing. I believe I did all the steps correctly, but was it I dumped the entire can of diced tomatoes in? Should I have drained it?

    Slow Cooker Alfredo Pesto Chicken and Pasta Recipe (10)

  19. Camille Beckstrand says:

    Did you make it in the slow cooker or the Instant Pot? If you made it in the Instant Pot, you will want to make sure that you saute it until the sauce is bubbly and starts to thicken. If you made it in the slow cooker, it should thicken up after adding the pasta - it will thicken as it cools down. I usually don't drain the tomatoes if I cook it in the slow cooker and haven't had a problem, but you definitely could drain them if yours was runny. I am sorry that it didn't turn out as you had hoped!
