If you’re on the lookout for the next snack to make for those times when you’re just chilling in front of the TV and binging shows, have I got the perfect one for you! These crispy fried oyster mushroom bites have a delicious crunchy coating on the outside with a tender and meaty center.
It’s becoming a favorite in my household, especially with how quickly I can make up a new batch.
And they’re also vegan-friendly! The only thing to note is that I use regular mayonnaise as part of my sauce, but substitute that out for vegan mayonnaise and all is well.
Crispy Mushroom Bites
These savory appetizers are essentially sliced oyster mushrooms that’s dipped into seasoned batter, then coated with panko crumbs before frying until it turns into a ravishing golden brown.
Serve it with a sauce of your choice, or try out this simple one that’s a combo of few ingredients: mayonnaise/vegan mayonnaise, ketchup, rice vinegar, sweet relish, and sugar. (Psst, it’s the same special sauce that I use in my In-N-Out Animal Fries Copycat recipe!)
