Notes

Ingredients (with measurements)
Fettuccine Alfredo Base
  • 8 oz fettuccine noodles, broken in half
  • 1 teaspoon olive oil
  • 3 cloves garlic, minced
  • Salt & pepper, to taste
  • 2 ½ cups low-sodium chicken or vegetable broth
  • 1 cup skim or 1% milk
  • 3 teaspoons cornstarch
  • ½ teaspoon onion powder
  • ½ teaspoon dried basil
  • ½ teaspoon dried parsley flakes
  • 1 cup freshly grated Parmesan cheese
These ingredients create a silky, creamy sauce with far fewer calories than the traditional version. The Instant Pot helps the pasta absorb all the flavors beautifully.
How to Make Skinny Instant Pot Fettuccine Alfredo
1. Sauté the Garlic
  • Set the Instant Pot to Sauté, add the olive oil, and heat it for a minute.
  • Add the minced garlic and cook for 10 seconds just long enough to release flavor.
  • Then turn off the sauté function to prevent burning.
2. Cook the Pasta
  • Add the fettuccine noodles and pour in the broth. Make sure all the pasta is submerged this helps it cook evenly.
  • Secure the lid, set the valve to Sealing, and cook on High Pressure for 3 minutes.
3. Natural Release
  • When the time is up, let the Instant Pot naturally release pressure for 6 minutes, then carefully open the valve to release any remaining steam.
  • Stir well to break apart any noodles that may have stuck together.
4. Make the Light Alfredo Sauce
In a small bowl, whisk together:
  • skim or 1% milk
  • cornstarch
When smooth, add this mixture to the Instant Pot along with:
  • parmesan
  • dried basil
  • dried parsley
  • onion powder
  • salt & pepper
5. Thicken the Sauce
  • Turn on Sauté again and cook until the sauce begins to thicken. It usually takes only 2–3 minutes.
  • Turn off the heat and let the pasta sit for a few minutes. The sauce will continue to thicken as it cools.
  • At this point, you can add extra parmesan if you prefer a richer, thicker sauce.
Tips for Perfect Instant Pot Alfredo
  • Use freshly grated parmesan it melts better than pre-shredded
  • Break the pasta in half so it cooks evenly
  • Avoid overheating milk adding it after pressure cooking prevents curdling
  • Let the sauce rest it thickens beautifully as it cools
  • Stir gently to avoid breaking the pasta too much
