These Keto Crab Stuffed Mushrooms are one of my favorite party appetizers!

Between the succulent crab and salty bubbling cheese you can’t go wrong. There’s no need for breadcrumbs in this recipe thanks to the extra parmesan cheese that gets sprinkled on top as it turns into a delightfully crunchy crust.

Great recipe, thanks!


How do you know what a serving size is?


Hi Emily, that depends on the number of mushrooms (e.g. fewer pieces if you use larger mushrooms). Depending on the total number of mushrooms used, it will be 2-4 mushrooms per serving.
