When I saw the recipe for French onion soup stuffed mushrooms on The Pioneer Woman, I knew I had to try this recipe. I love French onion soup and I love stuffed mushrooms. Combining them? Why didn’t I think of that? It’s delicious!
My version is slightly different than The Pioneer Woman’s simply because I used what I had on hand, but these were so good. My three-year-old even gobbled them up!
A package of good stuffing mushrooms. I used button mushrooms, but crimini are good, too.
2 tablespoons butter. Use the real stuff.
1 onion thinly sliced
1/2 cup beef broth
Swiss cheese. I used slices that I had on hand and cut them into about one inch rectangles.
I should note that when cooking I rarely follow exact measurements. I usually just “eyeball” ingredients. Now, I used to follow directions exactly, but I’ve found since I’ve been cooking for a while I really don’t need to. I said cooking. Baking is a whole different story. Maybe that’s why I’m not such a great baker?
Okay, once you’ve gathered your ingredients you’re going to want to gently wipe your mushrooms with a paper towel and remove the stems.
Get that tablespoon of butter melting in a frying pan and slice your onions.
Throw the onions in the pan of melted butter and let them caramelize to delcious onion goodness.
While the onions are working, place the mushrooms in a pan that you can pop a lid on with the other tablespoon of in the bottom. Let the mushrooms steam for a couple of minutes to soften them up.
Preheat your broiler.
Remove the mushrooms from the pan and place on a broiler pan.
When the onions are getting nice and caramelized, reduce the heat and add the beef broth. Let that reduce to a nice, delicious sauce.
Once you have a nice sauce with your onions, gently spoon a little bit of onions and sauce into each mushroom.
Add a small piece of Swiss to the top of each mushroom and place under your broiler for just a couple of minutes. Mine only went three minutes before they began to burn.
Remove the mushrooms with tongs and place on paper towels to soak up some of the juice and then enjoy!
