What I like about this recipe, like other Instant Pot pasta recipes on this blog, you don’t have to pre-cook the pasta. A one pot meal, with minimum effort and budget friendly ingredients. My secret ingredient to the most luxurious Alfredo sauce is adding a cup of mascarpone cheese. The result is a creamy and rich sauce, that tastes like it was made at a fancy Italian restaurant.

Instant Pot Alfredo Sauce and Pasta Recipe Tips:
- Chicken broth can be substituted with veggie broth, for a vegetarian version.
- Heavy whipping cream can be substituted with whole milk or evaporated milk.
- For a richer sauce, use heavy whipping cream instead of evaporated milk.
- You don’t have to pre-cook the noodles for this recipe.
- This meal can be made with other types of pasta, I like to use large shells or fusilli pasta.
- The mushrooms can be skipped.
- Instant Pot – I have the 6 quarts one. It makes weeknight meals so much easier.
Can I add chicken to this recipe?
Yes, you can. Cut a chicken breast into 1 inch cubes and add to the pot. Cooking time stays the same.
How do you reheat the Instant Pot Alfredo Sauce Fettuccine on the stove?
- Usually when refrigerated the sauce will thicken and the pasta will also absorb more of the liquid.
- To reheat, add pasta to a medium-large sauce pan over medium heat and add 1/2 to 1 cup of milk. Start with 1/2 cup, stir to combine and if needed add more, until you achieve the desired sauce consistency.
- You can also add cream instead of milk, or chicken broth.

Instant Pot Alfredo Sauce with Fettuccine
Instant Pot Alfredo Sauce is so easy to make, all you have to do is add all the ingredients to the pot, including the dry pasta and cook to perfection. This is the perfect dump and cook meal.
Ingredients
- 1 1/2 cups chicken broth or veggie broth
- 1 cup evaporated milk
- 1/2 cups heavy cream
- 1 teaspoon minced garlic
- 1 teaspoon dried thyme
- 1 teaspoon Italian seasoning mix
- 1/4 teaspoon red pepper flakes or less
- 1/4 teaspoon kosher salt
- 1/8 teaspoon ground black pepper
- 8 oz baby Bella mushrooms, sliced optional
- 1/2 lb dry fettuccine noodles broken in half
- 1 cup mascarpone cheese room temperature
- 1 cup parmesan cheese, shredded
- 1 tablespoon cornstarch
- 1 tablespoon water
Instructions
Using a kitchen scale, measure the pasta to make sure you are not using more.
- Add the following ingredients to the Instant Pot: broth, evaporated milk, garlic, thyme, Italian seasoning, red pepper flakes, salt, pepper and sliced mushrooms (if using). Stir to combine.
- Break the fettuccine noodles in half and add them to the pot. Distribute evenly on top, do not stir, just gently press to soak them into the liquid.
- Take the time to check if you have a bunch of noodles stuck together, gently soak them in the liquid, otherwise they will end up glued together when cooked.
- Pour the cream over the noodles.
- Cover and seal the lid. Make sure the valve points to Sealed.
- Change setting to Manual or Pressure Cook and adjust time to 5 minutes.
- Once Instant Pot beeps to show that it's done, wait 5 minutes (Natural Pressure Release) and after that do a quick release, by changing the position of the valve to Vent.
- Carefully remove lid and gently stir the noodles.
- Let them sit in the sauce uncovered for about 1-2 minutes.
- Add parmesan cheese and mascarpone, gently stir until fully combined.
- The sauce will thicken more as it cools off. However, if you would prefer a thicker sauce, mix cornstarch and water in a small bowl until fully combined.
- Select Sauté, add cornstarch slurry to the Instant Pot, stir and simmer for 2 minutes. Sauce will thicken more as it cools off.
- To thin out the sauce, add more milk or cream, and stir to combine. Simmer for 1-2 minutes.

This looks yummy!!
I’m a big fan of anything Alfredo. I seriously need to get an instant pot… I’m so behind on the trend and I’ve seen so many good recipes like this.
Looks scrumptious!! One of my favorites!
I’m going to have to try this. Alfredo is one of my favorite dishes. My oldest daughter is picky, and even she loves Alfredo.
Wow, that looks absolutely amazing. I love how quick and easy it is. The sauce looks so creamy!
I keep tossing around the idea of buying an Instant pot and then I see all of these delicious recipes and amazing meals that are created so effortlessly and I think its a no brainer…but I’m still hesitant! But the Alfredo has my stomach growling: -)
I just purchased an Instant Pot…I definitely need to try this!
You just can’t beat a good homemade Alfredo sauce! I love how easy this is to make. 🙂
I cant believe I was able to make this without cooking the pasta first… this was amazing!
I am so happy that you loved it 🙂 thanks for the feedback!
This is a perfect weeknight dinner! Yum!
This looks tasty! I love how easy it is to make. I can’t wait to try this recipe. Yum!
That looks so creamy and oh so delicious! You best believe I am making this soon!
This meal looks so thick and creamy. I would really enjoy making this for my family.
We love pasta over here and that looks so enticing. Thank you for the recipe. It’s going to be on the menu next week.
I love what you can do out of an instant pot! I have to try this!
Is the mascarpone cheese a requirement? If I left it out would it make a huge difference? This looks really good by the way!
it won’t be as rich and thick, that is the difference.
Any recommendations if the noodles did stick together? 😬 I thought I separated them enough but they bunched together.
Ugh sorry if they stuck together there is not much you can do, you can try the recipe with shells or fusilli pasta, its much easier to cook using those.
If I want to make a pound of pasta, does every ingredient, double too? This looks so yummy!
I would not recommend using so many noodles, they are hard to work with in the IP, they may stick, if you want to do a lb, use shells, or some other small pasta. Doubling should work.
This looks so quick and yummy!! Can you substitute the evaporated milk and mascarpone cheese with anything else?
cream and cream cheese 🙂
Is the italian seasoning mix, the dry seasoning in the packet or is it the actual dried herbs that you can buy in the spice isle?
the dried herbs
To add chicken, should they be sauteed first?
preferably yes.
A newbie here, but, all other recipes I’ve seen say to put in the milk products after the heating process is over, or it will curdle. But I wonder about this recipe? Tell me it works, I love alfredo!
It works 🙂 check the video to see how nicely it works 🙂 also I use evaporated milk NOT regular milk.
Will this recipe work if I make the noodles separate? This looks so good!
Honestly if you plan on cooking the noodles separately I really don’t see the point of cooking the rest in the IP, as it would not take longer on the stove. The noodles also absorb the liquid, so omitting them will change the recipe and I am not sure how it will work.
