Need a new go-to winter dinner? This easy sausage stuffed acorn squash recipe is made with just 7 simple ingredients and can be on the table in under 15 minutes!
Add the trivet to your instant pot and pour in 1 cup of water. Place the squash on the trivet. Lock the lid in place and turn the pressure valve to the sealing position.
Cook under high pressure for 5 minutes, then let the pressure release naturally for 5 minutes.
While the squash cooks, heat the oil in a skillet set over medium-low heat. Add the onions and cook, stirring frequently, for 5-7 minutes, or until light golden brown.
Stir in the sausage and increase the heat to medium-high. Cook 4-5 minutes, or until sausage is cooked through.
Add the spinach and apple. Cover and cook 2-3 minutes, until the spinach is wilted and the apple is soft.
Spoon 1 cup of the sausage mixture into each squash half. Sprinkle with red pepper flakes.
