Put 2 Tbsp butter and 1 Tbsp olive oil in your Instant Pot, along with the minced shallot. Press SAUTÉ (it should default to the NORMAL heat setting.) Sauté for a minute or so, stirring often, just to soften the shallot.
Add the 1 1/2 cups arborio rice and stir to toast the rice briefly, about another minute. Press CANCEL to turn the heat off.
Deglaze with the 2 Tbsp lemon juice and the stir in 3 cups of the stock (reserve the other half cup for later.) Lock the lid on the pot and set the vent to SEAL. Press PRESSURE COOK and set to 6 minutes. It will take the machine a few minutes to come up to pressure, then it will begin the 6 minutes of cooking.
Meanwhile place your chopped asparagus in a microwave safe bowl and microwave for 2 minutes. Give it a toss and set aside.
When the Instant Pot beeps after 6 minutes of pressure cooking, do nothing ~ let it sit for 5 more minutes.
Switch the vent to VENT and allow the pressure to come down. Open the lid and gently stir in the 1/2 cup Parmesan cheese and 1/3 cup mascarpone cheese. Stir in the chopped asparagus as well. Taste and add salt and pepper as needed.
If you would like a looser consistency for your risotto, simply press the SAUTÉ button and stir in more chicken stock.
Serve immediately with more Parmesan cheese and a sprinkle of lemon zest.
Notes
*If your asparagus is on the thicker side you may want to peel the outer layer of the lower ends, which can be tough.
