Ingredients
- Chicken breast: fresh boneless and skinless chicken ensures juicy bites that soak up the sauce look for pieces with a pale pink color and little to no smell
- Fettuccine pasta: classic shape for Alfredo clings to the creamy sauce well any brand with a smooth surface will work best
- Chicken stock: quality stock deepens the flavor and avoids blandness low sodium gives you more control over salt levels
- Heavy cream: brings that signature rich silky sauce be sure it is fresh and cold for the best texture
- Parmesan cheese: choose freshly grated for bold flavor and smooth melting skip the stuff in the green can
- Fresh garlic: adds essential aroma and depth peeled and finely chopped so it blends right into the sauce
- Salt and pepper: for balance crack your own pepper and salt right before cooking for peak freshness
- Olive oil: for browning chicken and garlic which helps every layer taste richer use extra virgin for the best aroma
Instructions
- Prepare the ingredients:
- Take a few minutes to clean and trim the chicken cut into bite sized pieces and butterflying if needed for even cooking mince the garlic and freshly grate the Parmesan this little bit of prep makes the rest go quickly
- Brown the aromatics:
- Pour olive oil into the Instant Pot and start the sauté function wait until the oil shimmers and add garlic stir gently for about one minute until you smell its fragrance this step sets the base for great flavor
- Cook the chicken:
- Add chicken pieces to the pot season with salt and pepper stir regularly and cook for about five to seven minutes until the pieces look lightly golden and cooked on the outside do not rush this part it is key for developing flavor
- Add liquids and pasta:
- Pour in chicken stock and give it a scrape to loosen any browned bits from the bottom then break the fettuccine in half so it fits lay the pasta down and gently push it under the liquid as much as possible to avoid sticking
- Pressure cook:
- Secure the lid and turn the pressure valve to sealing set the Instant Pot to manual or pressure cook for eight minutes let the flavors meld while the machine does the work
- Quick release and finish:
- After eight minutes carefully move the pressure valve to release steam allow all the pressure to escape before opening the lid immediately stir in cold heavy cream and Parmesan cheese mix briskly until the sauce is thick glossy and everything is coated
- Check seasoning and serve:
- Taste for salt and pepper adding more if needed then serve hot with extra cheese and maybe some chopped parsley

Parmesan is a secret family favorite in this dish my kids used to sneak little piles of cheese from the cutting board as soon as I started grating and it still makes me smile every time I stir it into the hot noodles
Storage Tips
This Instant Pot Alfredo is at its absolute creamiest fresh but leftovers keep for two days in the fridge use a glass container to avoid absorbing any fridge smells reheat slowly with a splash of milk to bring the sauce back to life stir gently over low heat and add a touch more cheese if needed
Ingredient Substitutions
No fettuccine try linguine or even penne for a different take if you use a gluten free noodle keep an eye on pasta texture since some brands might cook faster. For a lighter version swap half and half for heavy cream but the sauce will be a bit thinner. Vegetarians can use vegetable broth and swap the chicken for mushrooms or a bag of broccoli florets.
Serving Suggestions
Chicken Alfredo loves a crisp green salad on the side and I love some toasted garlic bread for soaking up extra sauce if you want to add color toss a handful of spinach or peas right at the end for a vibrant twist a lemon wedge really perks up the creamy flavors
Cultural and Historical Context
Although Alfredo pasta is often linked to Italian American kitchens it actually started with a restaurateur in Rome in the early twentieth century his secret was simple butter and cheese but the modern American version uses cream and chicken turning it into a full meal this recipe captures that spirit but with the convenience of the Instant Pot
Seasonal Adaptations
In spring toss in asparagus tips or peas for color and sweetness. For autumn chunk up roasted butternut squash or mushrooms and stir into the finished dish. Summer brings zucchini or fresh basil as bright additions and in the winter extra cracked black pepper adds cozy heat

This Instant Pot Chicken Alfredo is so easy and delicious you just might add it to your regular dinner rotation. It is comfort food perfection in under half an hour anytime you need something satisfying fast.
