Toss squash with 1 Tbsp olive oil and a little bit of salt and pepper. Arrange on a baking sheet. Bake for 20-25 minutes, stirring half way, until tender and lightly golden brown. Set aside.
Meanwhile, in the pressure cooker, heat remaining 2 Tbsp olive oil over medium high heat. Add mushrooms, cook for 5-6 minutes, until browned. Add shallots and garlic and cook for 2 minutes. Stir in the rice, stirring constantly for 30 seconds.
Pour in the white wine, and deglaze the pan. You want to cook for a few minutes, scraping up and bits that are at the bottom of the pan. Once the liquid is mostly evaporated stir in the chicken broth.
Close the lid, make sure it is locked and the vent is closed. Set to high pressure for 7 minutes.
After 7 minutes, let the pressure naturally release for 10 minutes, then quick release to finish.
Remove the lid, and stir in the butternut squash and Parmesan cheese. Season with salt and pepper to taste.
Serve immediately.
Notes
Recipe from Cooking Light No Pressure Cooker - Keep stock hot over low heat. Using a large skillet, follow instructions through adding the wine. Add 1 cup of stock, cook for 2 minute until the liquid is mostly absorbed, stirring often. Continue adding stock 1/2 cup at a time, stirring constantly until stock is absorbed before adding the next (about 26 minutes total). Stir in butternut squash, Parmesan cheese, salt, and pepper.
