Mashed potatoes stuffed mushrooms

These mashed potatoes stuffed mushrooms are such an elegant way to start a meal. They make for an healthy appetizer and since they are easy to grab, they are also perfect as small bites during gatherings. You will enjoy the delicious creamy filling combined with the chewiness coming from the mushrooms. They are vegan and gluten-free.

If you have been following me for a while, you must know by now how much I love mushrooms. Their chewy texture (which can mimic meat in some recipes), umami and savory taste and versatility are some of the things I like so much from them. I like to include them in pasta dishes like these vegan lasagna roll-ups or as the centre of healthy bowls like this vegan portobello poke bowl. They are packed with protein, so definitively a great vegetable to eat more regularly.

Tips to make these mashed potatoes stuffed mushrooms:

– Choose mushrooms that aren’t too small. They will hold better after cooking and you can stuff a good amount of potato filling inside. You will need to remove the gill (black part inside the mushrooms) with a small spoon after you remove the stems, but be as gentle as you can for this step not to break the mushrooms and keep the walls intact (so the filling does not leak).

– When you prepare the mashed potatoes, try to keep them from getting too runny, again, so the filling does not leak out of the mushrooms while cooking. I recommend to mash the potatoes very well first with a masher to remove as much of the lumps as you can. Then, add some almond milk a bit at the time until you reach a creamy texture that holds well together.

– You can stuff the mushrooms using a spoon, but it is so much easier (and the result looks better) to use a plastic bag.

Here is how to do it: Fill the bag with your mashed potatoes mixture pushing it towards one of the corner with your hand pressing on the bag. Then, cut the corner when you are ready for the stuffing step.
