Flavorful caramelized sweet onions, cheese, nutmeg - all you want from comforting French Onion Soup stuffed in meaty meatless Stuffed mushrooms!

A French Onion Soup that I pour in mushroom cups.. oh, I mean, "stuff in mushroom caps"!

It is officially last week of summer and I already welcomed fall last week. LOL! I guess I'm the eager one! Actually, Fall Season starts on 22nd September 2017. We have forecast of rain and thunderstorm for whole week... So, I felt these cozy stuffed mushrooms caps with hint of nutmeg will be perfect to serve on side for dinner! Gluten free and Meatless.

Stuffed Baked Mushrooms are comfort food which make great appetizer, snack, or even dinner side. I decided to make'em vegetarian, no meat no eggs. But I cheated a little bit by giving these a creamy slow-roasted meat kind-a flavor.. stuffing of cheese, herbs, and sweet caramelized onions. 

This sweet onion base recipe is everything you want in French Onion soup. Sweet caramelized onions, and hint of warm spice topped with a cheese crouton! Does it sound like a perfect, humble French Onion soup or what?!

Savita's Notes:

Baking Mushrooms: If you are ever unsure how long mushrooms will take to bake without burning the stuffing or cheese? I recommend par baking the mushrooms for 10 minutes without stuffing. Then fill in stuffing and continue baking until cheese is bubbling and mushrooms are cooked to your liking.

Yum, making a soup that is normally messy and immobile and making it into one bite. Such a great idea.
