Instant Pot Chicken Saltimbocca

Turn on a multi-functional pressure cooker (such as Instant Pot) and select Saute function. Melt butter in the hot pot; add olive oil. Sear chicken breasts until golden brown, 3 to 4 minutes on each side. Remove and set aside.

Stir shallot and garlic into the hot pot and cook until softened, 5 to 7 minutes. Deglaze the pot with chicken broth, bringing to a boil while scraping the browned bits of food off the bottom of the pan with a wooden spoon. Stir in lemon juice and lemon zest. Turn off the pot.

Place a trivet into the pot and place chicken on top. Close and lock the lid. Select high pressure according to manufacturer's instructions; set timer for 5 minutes. Allow 10 to 15 minutes for pressure to build.
