Your Complete Cooking Timeline
- Heat the olive oil in your pressure cooker’s sauté mode over medium heat. Toss in your chopped onion and cook until softened, about 5 minutes. You’ll see it gettin’ kinda translucent and sweet.
- Add in the garlic and sage, cook that combo for 1 minute till it’s super fragrant. You gotta be close here to not burn the garlic—keeps it tasty real good.
- Now dump in the chopped butternut squash and season everything with salt and pepper. Stir all that up so it gets coated in the lovely oil and flavors.
- Pour in the chicken broth and seal the lid with the sealing ring. Set the pressure cooker to high pressure and wait for the pressure build. Once it hits, let it cook for 8 minutes.
- After the timer beeps, do a quick release of the pressure to avoid overcooking. Open the lid carefully and use an immersion blender to purée the sauce right in the pot. If you don’t got one, blend in batches in a countertop blender. You want it smooth and creamy.
- Stir in the Parmesan cheese until it melts and makes your sauce creamy and rich. Give it a taste and add salt or pepper if you think it needs a tweak. Then serve it over your pasta and get ready to dig in!

Valve Hacks You Need to Know
- If you’re in a rush, quick release is your best bud—just flip that valve and let the steam out fast to stop cooking immediately.
- When you want the sauce thicker, try slow release for a few minutes before flipping the valve all the way open. This keeps it hot and lets liquid reduce a bit.
- Make sure your sealing ring is clean and fits snug so pressure build happens right and you get the best broth depth.
- Remember to wait a few seconds after pressure drops before opening the lid. You don’t want little hot splashes surprise ya.

Your Leftover Strategy Guide
Keep your sauce fresh by storing leftovers in an airtight container in the fridge. It should last up to 4 days just fine.
If you want to save it longer, freezing works great. Portion it in freezer-safe containers and thaw in the fridge overnight before reheating gently on the stove or in your microwave.
To reheat and keep the sauce smooth, stir it often and add a splash of broth if it seems too thick. That way it won’t clump or dry out.
