Instant Pot Skinny Fettuccine Alfredo: Step-by-Step Guide

Now that you have your ingredients ready, let’s dive into the easy steps to create your Instant Pot Skinny Fettuccine Alfredo.
Step 1: Sauté the Garlic
Turn on your Instant Pot and select the “Sauté” function. Add the oil and let it heat up for about a minute. Once hot, add the minced garlic and sauté for about 30 seconds until fragrant. Be careful not to burn it!
Step 2: Add the Noodles
Add the broken fettuccine noodles to the pot. Pour in the chicken broth (or vegetable broth) and stir well to ensure the noodles are submerged. Add salt and pepper to taste.
Step 3: Pressure Cook
Close the lid of the Instant Pot and ensure the valve is set to “Sealing.” Select the “Manual” or “Pressure Cook” setting and set the timer for 5 minutes.
Step 4: Quick Release
Once the cooking time is up, carefully perform a quick release by turning the valve to “Venting.” Be cautious of the steam!
Step 5: Thicken the Sauce
After the pressure has released, open the lid and stir the noodles. In a small bowl, whisk together the milk, cornstarch, onion powder, dried basil, and dried parsley flakes. Pour this mixture into the pot and stir well.
Step 6: Add the Parmesan
Turn the Instant Pot back to the “Sauté” function and cook for about 2-3 minutes, stirring constantly until the sauce thickens. Once thickened, remove the pot from heat and stir in the freshly grated parmesan cheese until melted and creamy.
Step 7: Serve and Enjoy!
Taste and adjust seasoning with additional salt and pepper if needed. Serve your Instant Pot Skinny Fettuccine Alfredo immediately, garnished with extra parmesan cheese and fresh herbs if desired.
Fit It to Your Goals

One of the best things about this Instant Pot Skinny Fettuccine Alfredo is that it can easily be adapted to fit your dietary needs:
- For a vegan version, substitute the parmesan cheese with a vegan alternative and use plant-based milk.
- Add in your favorite vegetables like spinach, peas, or broccoli for extra nutrients.
- For a protein boost, consider adding grilled chicken or shrimp.
- Swap out the fettuccine for whole wheat or gluten-free noodles based on your preference.
Steer Clear of These
While this recipe is packed with flavor and nutrition, there are a few things to avoid:
- Do not use pre-grated parmesan cheese, as it contains anti-caking agents that can affect the creaminess of the sauce.
- Avoid overcooking the noodles to prevent them from becoming mushy.
- Be cautious with added salt, especially if using regular chicken broth, as it can make the dish too salty.
Storage & Reheat Guide
If you have leftovers (which is rare because this dish is so good!), here’s how to store and reheat:
Allow the Instant Pot Skinny Fettuccine Alfredo to cool completely before transferring it to an airtight container. Store in the refrigerator for up to 3 days. To reheat, simply warm it up in the microwave in short intervals or on the stovetop over low heat, adding a splash of milk to loosen the sauce if necessary.
