Key ingredients & substitutions for Instant Pot Acorn Squash
- Acorn squash — Prime season for green winter acorn-shaped squash starts in early fall, so you may not find it as readily available throughout the year as other squash varieties. A ripe acorn squash will have a lighter orange or yellow spot on one side.
- Wild rice — Any kind of wild rice, or even brown rice, will work in this recipe. Just follow the cooking instructions on the package substituting vegetable or chicken broth for the cooking liquid to give it more depth of flavor.
- Italian Sausage — Select either mild or spicy bulk ground sausage to suit your own tastes. For a vegetarian option, just leave it out.
- Aromatics — Shallots and garlic are so very important in building a good flavor base for this recipe.
- Steamed chestnuts — Full disclosure, this is the first time I’ve ever used steamed chestnuts (I had been gifted a sample a few weeks ago), but I love the added texture and flavor they give to the filling. If you’re not a fan, it’s totally fine to omit.
- Dried cherries — Just a handful adds a chewy sweet bite! Dried cranberries or figs would also be delicious.
- Nuts — For a little added crunch, add walnuts or pecans to the wild rice filling.
How to make instant pot acorn squash?
STEP 1 | Cook the rice
Unless you’re using an instant wild rice mix, get the rice started first. I used Lundberg Wild Blend Rice which takes 45 minutes on the stove.
Rinse the rice under cool running water, then cook using vegetable broth or chicken broth for the liquid according to the package directions.
STEP 2 | Sauté the sausage, shallots, and garlic
Set the instant pot to the SAUTÉ function. Once the pot is hot, add a tablespoon of olive oil and swirl to coat the bottom. Add the Italian sausage, shallots, and garlic.
Cook and stir until the sausage is no longer pink and the shallots are translucent. Use a slotted spoon to remove the mixture to a paper towel lined plate.
- Make the filling ahead of time, then just warm it up when you’re ready to cook and stuff the squash.
STEP 3 | Pressure cook the squash
Place the trivet into the bottom of the pot and pour in a cup of water. Add the acorn halves to the pot cut side down.
Lock the lid and set the valve to sealing. Cook on HIGH pressure for 6 minutes. Allow the instant pot to naturally release for 5 minutes, then rapid release any remaining pressure. When the pin has dropped, remove the lid and place the squash on a serving tray.
STEP 4 | Stuff the squash
When the rice is finished cooking, transfer to a large bowl. Add the cooked sausage, chopped steamed chestnuts, walnuts, and dried cherries. Season with sage and salt.
Spoon the rice sausage mixture into each squash.
- Garnish stuffed acorn squash with a few pomegranate arils or fresh sage leaves.
- Serve along side oven-roasted pork tenderloin and cooked apples.
