Instant Pot® Acorn Squash Stuffed With Italian Sausage

Step 1
Turn on a multi-functional pressure cooker (such as Instant Pot®), add olive oil, and select Saute function. Add sausage, onion, and bell pepper. Cook until sausage is browned and crumbly, 5 to 7 minutes. Add 1/4 cup marinara sauce, 1/4 cup mozzarella cheese, bread crumbs, garlic, oregano, and black pepper. Stir until well combined.

Step 2
Transfer mixture to a bowl; drain and discard any excess grease.

Step 3
Stuff each squash half with sausage mixture. Place trivet inside the pressure cooker pot and add water. Place stuffed squash halves on the trivet. Close and lock the lid; be sure vent is sealed. Select high pressure according to manufacturer's instructions; set timer for 4 minutes. Allow 10 to 15 minutes for pressure to build.

Step 4
Release pressure using the natural-release method for 7 minutes. Release remaining pressure carefully using the quick-release method according to manufacturer's instructions, about 5 minutes. Unlock and remove the lid.

Step 5
Carefully transfer squash halves to a serving plate and top with remaining marinara sauce and mozzarella cheese.
