Instant Pot® Penne alla Vodka
2 Tablespoons Unsalted Butter
1 Tablespoon Olive Oil
¾ Cup Finely Chopped Yellow Onion
3 Cloves Garlic, Minced
½ Teaspoon Crushed Red Pepper
½ Cup Vodka
2 ½ Cups Water
1 (16 Ounce) Package Uncooked Penne Pasta
2 Teaspoons Kosher Salt

Step 1 Turn on a multi-functional pressure cooker (such as Instant Pot®) and select Saute function. Select High temperature setting, and preheat the pot for 1 to 2 minutes. Add butter and oil. Add onion and cook, stirring constantly, until translucent, about 3 minutes. Add garlic and crushed red pepper, and cook, stirring often, for 1 minute.
Step 2 Pour in vodka and cook until reduced by half, about 3 minutes. Cancel Saute function. Stir in water, penne, and salt. Pour tomatoes over penne; do not stir. 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.
Step 3 Release pressure carefully using the quick-release method according to manufacturer’s instructions, about 5 minutes. Unlock and remove the lid. Stir in cream and Parmesan cheese and chopped rotisserie chicken or cooked shrimp, if using; let stand for 3 minutes. Stir in pepper.
