Place the Instant Pot on the Saute-Normal function. Add the olive oil and garlic and cook until fragrant - about 2 minutes.
Add the pasta, water and salt - no need to stir.
Attach the lid and ensure the valve is in the sealing position. Turn the instant Pot to pressure cook for 4 minutes.
When the Instant Pot has finished, release the pressure by switching the valve to the "venting" position - be careful, it will steam!
Add the remaining ingredients (parmesan, cream, butter, lemon juice, lemon zest and peas) and stir to combine.
Place the lid back on the Instant Pot (it should be on the keep warm setting) and let it sit for 2 to 3 minutes, or until the peas have warmed through. Season with salt and pepper to taste.
