Peel, core, and chop your pears into large pieces.
Place the prepared pears in your slow cooker. Tuck in the cinnamon stick. Pour the water over the top.
Cover the slow cooker with the lid. If you’re using a Ninja Foodi or Instant Pot, leave the steam vent open.
Slow cook unsweetened applesauce substitute for 6 hours on high. They’ll look very watery at this point, but once you mash them down, they’ll develop a more applesauce-like consistency. After mashing, turn the slow cooker to low and cook an additional hour.
The varieties of pears you use do determine how watery this faux applesauce turns out. If it's still too watery after cooking, you can heat it on the stovetop to get more water off. (If you’re using a Ninja Foodi or other multipurpose cooker, simply take the lid off and use the “high saute” function.)
Once it’s ready, remove the cinnamon stick, and let the sauce chill in the fridge. I like to leave this sauce a little chunky. However, you can blend it with a food processor or immersion blender for a smoother fruit puree. Enjoy!
