Instant Pot® Shrimp Scampi Orzo

Place shrimp in a large bowl and set aside.

Heat olive oil in a multi-functional pressure cooker (such as Instant Pot®) on Saute function. Add shallot and saute, stirring, for 1 1/2 minutes. Mix in garlic, lemon zest, red pepper flakes, salt, and pepper. Cook and stir until garlic is fragrant, about 1 1/2 minutes. Add the shallot mixture to the shrimp, stir in lemon juice, and refrigerate.

Clean inner pot, return to the Instant Pot®, and select Saute function. Melt butter and stir in orzo. Keep stirring until all the orzo is coated with butter, about 1 1/2 minutes. Add shrimp stock and white wine; stir to combine. Bring to a boil. Close and lock the lid.

Select high pressure according to manufacturer's instructions; set timer for 4 minutes. Allow 10 to 15 minutes for pressure to build.

Release pressure carefully using the quick-release method according to manufacturer's instructions, about 5 minutes. Unlock and remove the lid. Place the prepared shrimp in a single layer on top of the orzo.

Close and lock the lid. Select high pressure and set timer for 1 minute. Allow 5 to 10 minutes for pressure to build.

Release pressure carefully using the quick-release method according to manufacturer's instructions, about 5 minutes. Serve warm with fresh parsley and lemon slices for garnish.
