French Onion Soup Stuffed Mushrooms

Important note: this recipe has absolutely nothing to do with Thanksgiving.

I’m so glad I got that out. I feel cleansed!

I whipped up these little mushroom appetizers yesterday for two reasons:

1. I love stuffed mushrooms in any form and am always thinking of fun little variations.
2. I wanted to.

You’ll love these! Make them for a Thanksgiving appetizer or (fast forward!) holiday party. Watch them disappear before your eyes.

(And here are a couple of other ‘shroom recipes if you’d like to have a variety):

Original Stuffed Mushrooms
Mushrooms Stuffed with Brie


Begin by cutting an onion in half from root to tip. Next, peel off the skin and slice the onions thinly.


Melt butter in a medium skillet.


Throw in the onions and toss them around.


Cook for about fifteen minutes, then pour in wine and broth.

You can leave out the wine if you’re a good girl or boy.

When it comes to cooking with wine, I’m not a good girl.

I’m also not a boy.

I realize that made no sense.


Let the onions cook down until most of the liquid is gone, about 5 minutes. Then splash in some Worcestershire sauce. Stir it around to combine.


Grab some mushrooms and pull off the stems.


Melt some butter in a large skillet.


Throw in the mushrooms.


Sprinkle on a little salt, then just toss them around to cook ‘em for a couple of minutes.

But just a couple.


Put the mushroom caps in a baking dish.


Fill the caps with a nice amount of onions. You want to taste these suckers!


Next, grate up some Gruyere cheese.

Yum and a half.

(You can also use Swiss.)


Sprinkle a generous amount of Gruyere on the top of the ‘shrooms.


Then bake ‘em in a 325 degree oven for about 10 to 15 minutes, or until the cheese is melted. Then crank up the broiler in the oven and let them broil for a couple of minutes, or until just starting to turn brown on top.




Sprinkle on some minced parsley, just to finish them off.


They’ll be nice and moist on the bottom…


So you can set them on a paper towel for a sec, just to blot the excess moisture.


Serve them to hungry humans.

(That includes you!)


You’ll absolutely love them.
