Turn on Sauté function for 15 Minutes. Once preheated, add the butter and stir until melted.
Add the lemon slices to the pan without overlapping. Sear on one side for 1-2 Minutes, or until lightly browned. Turn the lemon slices over and Sauté for another 1-2 Minutes. Remove from the pan.
Add the garlic and Sauté for 1 Minute, or until fragrant. Stir frequently and be careful to not burn the garlic. It will cook quickly!
Add the lemon slices back to the pot. These will break down during the cooking process and add a zing to each bite!
Pour in the chicken broth and heavy cream, and stir in the salt.
Add the pasta and toss to coat. Make sure all noodles were tossed in the liquid!
Pressure cook on High for 2 Minutes. Allow the pot to naturally release for 3 Minutes, then flip the valve to release any remaining pressure.
Add the grated parmesan and additional tablespoons of heavy cream. Toss to combine until the cheese has melted from the residual heat. Add a few more tablespoons of heavy cream if necessary.
Serve with an additional sprinkle of parmesan and top with minced parsley. Enjoy!
