Break 8 ounces fettuccine noodles in half and set aside.
Turn Instant Pot to Sauté. Add 1 teaspoon oil. When oil is hot, add 3 cloves garlic (minced) and stir about 10 seconds, then turn the Instant Pot off.
Add the broken fettuccine to the pot and pour in 2 1/2 cups low-sodium chicken broth (or vegetable broth), pressing the noodles down so they are mostly submerged.
Close the lid and set the valve to SEALING. Cook on Manual (High Pressure) for 3 minutes.
When the cook time ends, allow a natural pressure release for 6 minutes, then carefully turn the valve to VENTING to release any remaining pressure. Open the lid.
Stir the pasta to break up any pieces that have stuck together.
In a small bowl, whisk 1 cup milk (skim or 1%) with 3 teaspoons cornstarch until completely smooth. Add this milk-cornstarch mixture to the Instant Pot along with 1/2 teaspoon onion powder, 1/2 teaspoon dried basil, 1/2 teaspoon dried parsley flakes, and 1 cup freshly grated Parmesan cheese. Season with salt and pepper to taste.
Turn the Instant Pot to Sauté and gently stir the mixture until the sauce just begins to thicken, about 1–2 minutes. Do not boil. Turn the Instant Pot off.
Let the pasta sit for a few minutes to allow the sauce to thicken further before serving. If needed, add additional Parmesan to reach your desired thickness.
