NOTE: If you haven't cooked Pasta in the Instant Pot before, it's really easy, and quick, but, you must make sure it's completely covered in the liquid, or sauce. Don't put milk or cheese in the pot with Pasta, as it will curdle while under pressure! Add any milk or cheese after the Pasta has cooked. Don't add the Parmesan cheese to the Pot, just top the Pasta with the cheese before serving. You can also top this dish with crumbled bacon, or sliced or chopped chicken. Rotisserie chicken would be a quick addition to this pasta dish. You can serve with a side salad, or green beans for a quick and delicious meal.
ALSO: If you don't prefer crushed red pepper, just add a pinch instead of the measured amount; you'll still get the flavor without as much heat. If you like hot spicy dishes, you can add a little more pepper to taste.
