How to Make Cauliflower-Stuffed Mushrooms
Separate two eggs, then mix the egg yolks, cauliflower mash, and some heavy cream together.
If you're planning on adding any extra ingredients, do it now! Here are some suggestions:
- minced garlic
- shredded cheese
- cooked and crumbled bacon
- chopped fresh herbs
- wholegrain mustard
A lot will depend on whether the cauli mash was flavored originally. If you use leftover cheesy cauliflower mash (recipe coming soon!) - you might not need any additions!
Season generously with salt and pepper. In a separate bowl, whisk the egg whites until stiff peaks form.
Carefully fold the egg whites into the cauliflower mixture.
Remove the stalks from four large portabella mushrooms, and place them on a small baking sheet. Divide the stuffing mixture between the mushrooms.
Bake in a preheated oven until the stuffing has puffed up and has turned golden brown on top.
Drain the mushrooms on paper towels (they will have released some juices), then serve, garnished with fresh chives.
The filling is light and airy, and is a fantastic contrast to the almost meaty mushrooms!
