Turn Instant Pot to sautee and add sausages. Cook until browned and remove from Instant Pot.
Put broth, cream, garlic powder, pepper and macaroni pasta in Instant Pot, making sure macaroni is covered by liquid (no need to stir). Add sausage on top of noodles.
Using Manual setting, set for 3 minutes. Once complete, natural release for 3 minutes, then quick release.
Stir well. Add sauce to macaroni and sausage and stir.
Add about ¼ of the cheese and stir until combined. Repeat until all cheese is incorporated. Allow to rest for 3 minutes to thicken then serve! Add parsley garnish if desired.
If it seems like it has curdled, with a good stir, it will be perfect.Because the Instant Pot is hot (from cooking the sausage), this recipe takes only 3 minutes for perfectly cooked macaroni (for macaroni with a cook time of 7-8 minutes).Other types of pasta may take different amounts of time.
