French Onion Stuffed Mushrooms are a low fuss, but crazy delicious appetizer or size dish. Perfect for unexpected guests or jazzing up a boring dinner menu!
Stuffed Mushrooms are Overly Complicated
I love these French Onion Stuffed Mushrooms because they are casual and fuss-free – and delicious. My husband and I have pretty much never met a stuffed mushroom we didn’t like. But I tend not to make them often at home because the recipes can be overly complicated.
I am not sure why. But generally stuffed mushrooms seem like they are supposed to be served at a restaurant. Not eaten standing over the stove. (Not that we do that…)
French Onion Stuffed Mushrooms are Casual Food
But these French Onion Stuffed Mushrooms are our solution to this formerly high-brow food. Our mushrooms have gone casual. For one, they only take few minutes to prepare – which means I might actually make them on a weeknight.
Secondly, if you are freezer crazy like I am, I always caramelize piles of onions and freeze them so they are always handy. If I decide I can’t live without these on a Tuesday, these are already halfway there.
Stuffed Mushrooms are AWESOME!
These French Onions stuffed Mushrooms are really so delicious. You might not want to share them. But just in case you do, they make a great party appetizer. Especially around the holidays when guests appear out of the woodwork, Keep the ingredients on hand and you won’t have to stress about what to feed everyone who comes by.
Don’t know what to do with those leftover mushrooms?
Don’t throw those mushroom stems away!!! Nobody will ever care (or know) that it is stems only in this Sausage and Mushroom Quiche. Add a salad and it is a great dinner. Add a side of fruit and it is a great breakfast!
This Asparagus and Mushroom Saute is also a great way to use up those stems. And you have NEVER tasted asparagus so good!
