Once the oil is hot, add broccoli florets and saute for a minute. Transfer the florets to a plate and set them aside.
Add garlic, onions, and chicken, and saute for a minute or until the chicken is pale white, stirring frequently.
Now add chicken broth, heavy cream, cream cheese, salt, oregano, and red pepper flakes and stir nicely.
Add pasta to the pot and stir to mix. Push the pasta gently downwards, just enough to submerge it into the broth.
Close the lid of the instant pot and set the valve to the sealing position.
Press PRESSURE COOK and set the timer to 3 minutes at high pressure for al dente pasta. Cook for extra 1-2 minutes for slightly more cooked pasta.
Once the timer goes off, do a quick pressure release.
Open the lid and add sautéed broccoli, parmesan cheese, and parsley and mix gently.
Add some milk if the pasta is too thick for your liking.
Taste the sauce and adjust for salt and pepper. Serve!

Notes
I made this pasta recipe in my 3-quart Instant Pot, but if you want to double the recipe, use a 6-quart Instant Pot instead. The cooking time will remain the same.To make this recipe vegetarian, skip adding chicken and replace the chicken broth with veg broth.If using frozen broccoli, add it directly from the freezer instead of thawing it.
