Build Instant Pot Skinny Fettuccine Alfredo Step by Step

Step 1: Sauté the Garlic
Start by setting your Instant Pot to the sauté function. Add the teaspoon of oil and let it heat up. Once hot, add the minced garlic and sauté for about 1 minute, stirring frequently until fragrant. Be careful not to burn the garlic!
Step 2: Add the Noodles
Next, add the broken fettuccine noodles directly into the Instant Pot. Pour in the low-sodium chicken or vegetable broth, making sure the noodles are submerged.
Step 3: Season It Up
Sprinkle in salt and pepper to taste. Stir the mixture gently to help the noodles separate.
Step 4: Pressure Cook
Close the lid of the Instant Pot and set the valve to sealing. Select the manual or pressure cook setting and set the timer for 6 minutes. Once the cooking time is complete, do a quick release of the pressure.
Step 5: Create the Creamy Sauce
After releasing the pressure, carefully remove the lid. In a small bowl, whisk together the milk, cornstarch, onion powder, dried basil, and parsley flakes until smooth. Stir this mixture into the cooked noodles in the Instant Pot.
Step 6: Add the Cheese
Set the Instant Pot to sauté again and gently stir in the freshly grated Parmesan cheese. Continue to stir until the cheese has melted and the sauce is creamy and well combined.
Step 7: Serve and Enjoy!
Taste and adjust seasoning if necessary. Serve your Instant Pot Skinny Fettuccine Alfredo immediately, garnishing with additional parsley if desired.
