  • 6 or 8 quart Instant Pot


  • 2 acorn squash, sliced in half with seeds and strings removed.
  • 1 lb ground Italian sausage (mild or hot)
  • ½ cup onion, diced
  • ½ cup sliced fresh mushrooms
  • 2 cups shaved Brussels sprouts
  • ½ tsp dried oregano
  • ½ cup fresh grated Parmesan (I love using pedals for this recipe)
  • 1 tsp salt
  • 1 cup water (to get the pot to come to pressure)



  • Select saute feature on the Instant Pot, and once hot, add the ground Italian Sausage, mushrooms, and the onion. Saute until cooked.
  • When the sausage is cooked, at the salt, oregano, Brussels sprouts. Stir for 1 minute until the shaved sprouts cook down.
  • Remove the stuffing mixture from the Instant Pot liner and place it into a large bowl.
  • Add the Parmesan to the mixture and stir. Cover with foil and set aside.
  • Pour 1 cup of water into your Instant Pot liner.
  • Place your trivet (it came with your Instant Pot) into the water.
  • Stack your acorn squash halves into the pot.
  • Secure the lid, set to sealing, and set the function to STEAM for 6 minutes.
  • When the pressure cycle is complete, quick release the pressure.
  • Carefully remove the squash from the pot using tongs.
  • Stuff the squash with the sausage mixture.
  • OPTIONAL: broil the stuffed squashes if you prefer a crispy topping.
  • Enjoy!
