Preheat oven to 350°F/ 175 degrees C. Spray foil lined baking sheets with non-stick cooking spray or line baking sheet with parchment paper.
Wash mushrooms, remove stems and set the stems aside . ( *The stems easily pop off when you gently pull them to the side). Finely chop HALF the stems.
20 fresh, large white or brown mushrooms, washed and stemmed
With a small spoon, gently scoop out mushroom caps so there is room for stuffing. Add mushroom cap scrapings to finely chopped stems in a small bowl.
In a microwave safe bowl, cook butter, onion, garlic and only HALF mushroom stems and scrapings from the mushroom for 4 minutes. You can save the other half for soup stock, eat them or discard in the compost bin.
In a medium bowl, mix together instant mashed potatoes, cheese, bacon bits, sauerkraut, sour cream, salt, pepper. * Eliminate bacon bits if making vegetarian.

Notes
Expert Recipe Tips;
Choose mushrooms of similar size so they cook evenly and finish at the same time. This also makes the Weight Watchers points easier to estimate per mushroom.
Don’t skip scooping the caps — removing a bit of the inside flesh gives you more room for filling and prevents the mushrooms from releasing too much moisture while baking.
Use thick mashed potatoes for the best texture. Whether using instant or leftover mashed potatoes, avoid potatoes that are overly creamy or loose, or the filling may spread instead of mound nicely.
Squeeze the sauerkraut very well before chopping. Excess liquid can make the filling watery and dilute the pierogi flavor.
Cook only half of the mushroom stems as directed. This adds mushroom flavor without introducing too much moisture into the filling.
Let the filling rest for a few minutes before stuffing the mushrooms. This allows it to firm up slightly and makes the mushrooms easier to fill neatly.
Use a small spoon or cookie scoop for evenly portioned stuffing. This helps ensure consistent size, appearance, and WW points per mushroom.
Bake uncovered so excess moisture can evaporate and the tops lightly brown instead of steaming.
Finish with a light sprinkle of parmesan rather than mixing it into the filling — this creates better flavor contrast and a slightly crisp top.
For mixed dietary needs, leave the base filling vegetarian and sprinkle bacon bits on top of only the bacon version after baking so they’re easy to tell apart.
Garnish just before serving with fresh dill or parsley for maximum color and flavor impact.
Serve immediately for best texture — these are at their peak when hot, with a creamy filling and tender mushrooms.
StorageStore leftover potato stuffed mushrooms in a single layer in an airtight container in the fridge for up to 3 days. These can also be made a couple of days ahead. For best results, do the prep (stuff them) then cook them just prior to serving.They do not stand up well to freezing.Â
