Instant Pot Alfredo Pasta comes together with just 5 ingredients! Creamy, rich, and indulgent, this easy recipe is ready in just 30 minutes. You’ll have a restaurant-quality, luscious pasta dinner with minimal effort!
👉 This instant pot alfredo pasta recipe was originally shared in 2018 with chicken. Since then, it’s been updated to a simple version without chicken, and refreshed with new photos and step-by-step instructions in January 2025.
Similar to the one pot alfredo, this restaurant-quality meal is perfect for any day of the week! While this is a vegetarian version of alfredo pasta, it’s super easy to customize with chicken or broccoli. Plus, it's a simple dump-and-go recipe that makes dinner a breeze!

Table of contents
Ingredients you'll need
- Linguini: While alfredo is traditionally made with fettuccine, I prefer linguine for this alfredo pasta recipe. It cooks slightly softer in the pressure cooker, creating a luscious, creamy sauce. That said, feel free to swap in fettuccine if you prefer!
- Broth: As always, I prefer using 33% reduced-sodium broth to better control the salt, but you can easily swap it for vegetable stock or even water if you prefer.
- Garlic: You’ll need 1 to 2 cloves of minced garlic, but feel free to use garlic powder or skip it altogether. Love garlic? Check out our roundup of 17 must-try recipes for garlic lovers!
- Heavy cream: This is an indulgent dish, so there's no substitute for heavy cream. Using milk or half-and-half may cause the sauce to curdle.
- Parmesan cheese: As I mention in the parmesan cheese recipes, use freshly grated parmesan for a flavor that canned cheese can't match.

Variations
Chicken - Place chicken tenders or sliced chicken breasts on top of the linguine.
Shrimp - Refer to our instant pot shrimp alfredo for a detailed recipe.
Fettuccini - Swap the linguine for 8 ounces of fettuccine noodles. Fettuccine will be slightly firmer than linguine, adding a bit more texture to the dish.
👩🍳 Before serving: Alfredo pasta may thicken slightly as it sits. Simply stir in a splash of hot water to loosen it up before serving!
👉 How to store: Store any leftovers in an airtight container in the refrigerator. The sauce may thicken after chilling, but simply add a splash of milk or water when reheating. I recommend using the microwave for quick and easy reheating.

Equipment
Ingredients
- 1 ½ cups chicken stock I used 33% reduced sodium
- 2 cloves garlic finely chopped
- ½ teaspoon salt adjust based on the stock used
- ¼ teaspoon pepper
- 1 ½ cups heavy cream
- 8 ounces linguini broken in half
- ¾ cup grated parmesan
Instructions
- Add the stock, garlic, salt and pepper in the inner pot of the instant pot.
- Gently pour the heavy cream on top, but don't stir.
- Layer the broken linguini noodles on top, crisscrossing the direction of the noodles for each layer. This will help prevent the noodles from sticking together.
- Close the lid, be sure the vent knob is sealed. Set to cook on high pressure for 6 minutes.
- Once the cooking time is complete, let the pressure release naturally for 10 minutes. Afterward, carefully release any remaining pressure.
- Open the instant pot, stir in the parmesan and mix well to combine. Don't worry if there’s extra liquid—the noodles will absorb it as they sit.
- Serve after few minutes with with additional parmesan cheese if desired.

My folks bought me a pressure cooker for my birthday, and it's amazing! I usually use it to cook soup and chicken pieces, so will have to try a pasta dish soon 🙂 The perfect excuse to make this recipe!

Hi Maria,
2 questions: 1) Any adjustments needed if using a 6qt Instant Pot?
2) Could shrimp be substituted for chicken in this recipe, and if so, would the cook time need to be adjusted? I made your shrimp pasta in tomato cream sauce last week and it was DELICIOUS (first time using my Instant Pot- total success) so I have shrimp on my mind again. Thanks so much!

Hi Laura,
1) This recipe will work perfectly in all sizes.
2) We have a recipe for Instant Pot shrimp Alfredo - https://www.kitchenathoskins.com/instant-pot-shrimp-alfredo/
You may sub fettuccini instead of bow tie.
Glad you loved the Shrimp pasta, enjoy:)
