  • 2 tablespoons unsalted butter
  • 2 garlic cloves, minced
  • 1 and 1/2 cups chicken stock, refer notes (I used 33% less sodium)
  • 1 teaspoon salt (refer notes) or to taste
  • 1/4 teaspoon ground black pepper or to taste
  • 1 and 1/2 cups heavy cream
  • 8 ounces fettuccine pasta, broken in half
  • 3/4 pound boneless, skinless chicken thighs, chopped (about 3 thighs)
  • 3/4 cup grated parmesan cheese, or more if desired


  • Heat Instant pot to saute mode. 
  • When hot, add butter and let it melt. Add chopped garlic into the pot and saute for 20 to 30 seconds, until it begins to get golden. 
  • Press cancel and add chicken stock, salt and pepper. Give a good stir and please note that it is very important not to stir after this step.
  • Pour in heavy cream (DO NOT STIR) and add fettuccini on top, gently pressing the pasta to be submerged into the liquid (DO NOT STIR).
  • Place chicken on top in an even layer (DO NOT STIR).
  • Close and lock lid (making sure the valve is in sealing position).  Select manual cooking mode and set for 6 minutes (for al dente pasta ) or 7 minutes (for softer pasta).
  • Once cooking time is done, let it be in warm mode for 7 minutes (or after 9 minutes for softer cooked pasta).
  • Release pressure and open lid and stir in parmesan cheese. The pasta will be liquidy at this point but will thicken as it cools (do not cover).
  • Serve after few minutes with additional grated parmesan if desired.


Salt - Salt will depend on the stock used and your taste. I found that 1 teaspoon salt was perfect for this recipe. Also, I used 33% chicken stock. If you are using regular / no sodium chicken stock, then please adjust salt accordingly. 
Chicken stock - I used 33% chicken stock.
If you are using a smaller instant pot and liquid sprays out when trying to quick release, then simply turn valve back to seal and wait for few more minutes before trying again.
Pasta – I used the classic fettuccini for this recipe, but penne or Bow Tie works just as well.
Chicken – Boneless, skinless chicken thighs is always my go-to cut of meat, but boneless, skinless chicken breasts may be used instead.
