Storing and Reheating Fettuccine Alfredo
Storage:
I usually store leftover fettuccine alfredo in an airtight container and keep it in the refrigerator for up to 4 days. This way, the pasta stays fresh, and the sauce holds its flavor without drying out.
Reheating:
For reheating, place the pasta in a microwave-safe bowl, add a small splash of water or milk to loosen the noodles, and microwave until it heats evenly. If you prefer, you can use a small saucepan on the stovetop over low heat, stirring gently until the creamy sauce returns and the pasta feels just-made.

When making noodles in a pressure cooker, I usually press Manual Pressure Cook on high and set it for 7 minutes.

How to thicken Alfredo sauce in Instant Pot?
A simple chef’s trick for thick and creamy sauces is adding back starch from the Pressure-cooked noodles. After the Fettuccine Alfredo is done in the Instant Pot, let it release for a short time, then cook quickly on sauté with the starch water to make the sauce extra thick and even more delicious.
Why is my fettuccine Alfredo not creamy?
Your Fettuccine Alfredo may lose its creamy texture due to overheating the sauce, adding cheese quickly at a high temperature, or using low-fat dairy and pre-shredded cheese. To fix it, use a fresh block of Parmesan, stir in a little milk or starchy water, add high-fat butter, and serve immediately on warm plates, keeping the heat lower while cooking the pasta to keep the flavor rich and smooth.
Can you cook dry pasta in the Instant Pot?
Yes, you can place dry pasta in the inner pot of the Instant Pot, then add salt, a little olive oil, and enough stock or water to just cover it. Close the lid, set the valve to sealing, then Set Manual Pressure Cook for 5-6 minutes or follow the time on the box directions.
What is the best cheese for Alfredo sauce?
The best cheese for Alfredo sauce is freshly grated Parmesan or Parmigiano-Reggiano, as they melt smoothly and give a complex flavor with real richness. Avoid pre-shredded varieties since anti-caking agents can make the sauce grainy or lumpy; you can also try Pecorino Romano for a sharper taste or Gruyere for a nuttier, creamier texture.
