Pour stock into the Instant Pot insert, then add the rest of the ingredients including the best ever sea salt flakes. (but don't add the spinach or Parmesan yet!).
Close the lid and turn the vent to sealing position. Set the Instant Pot to manual high pressure for 6 mins.
Cook till done, then allow for a natural pressure release (NPR) of 6 mins before performing a quick release to let out remaining steam.
Open the lid, stir in the Parmesan and baby spinach and let it wilt before serving.
Notes
Tips for Making Creamy Bacon Pasta
Make sure the pasta is fully submerged before cooking.
When you first open the IP, there will be a bit more liquid, but if you mix and let stand for a bit the liquid will be absorbed.
And if you like your pasta with lots of sauce, add an extra half to one cup of stock or cream. YUM.
Feel free to double or (even triple) the ingredients in this recipe to feed a crowd without having to adjust the cook time at all!
You can sprinkle in even more Parmesan cheese, or add some grated mozzarella for extra cheesy goodness.
Add cooked chorizo or sausage for even more meaty goodness.
Add some chopped sun dried tomatoes for extra flavour.
No spaghetti on hand? No problem. You can easily swap in the pasta of your choice (eg penne, fusilli, shell pasta).
