Boursin Caramelized Onion Mushrooms

One day while at the farmers market stand I got to talking to the owner. She was talking about different ways to cook fresh vegetables and that she made a creamy mushroom dish last night. It sounded so good and got me thinking of different ways to recreate it. I wanted to bake them instead of on the stove like most creamy mushroom recipes. Then it hit me, what makes everything yummy? Cheese! I remembered the amazing steak at one of our favorite restaurants. It is Boursin Cheese on top of a steak, we call it the "Boujee Filet" and it is sooooo good. I decided to combine this delectable cheese with mushrooms to create a creamy and cheesy dish full of flavor.

This Boursin Caramelized Onion Mushroom side dish is extremely easy with very little hands on time. Simply combine mushrooms, sliced onion and some seasonings in a pan, place Boursin cheese in middle and bake. Something magical happens when you bake this cheese, it becomes extra creamy and enhances the flavors. When baking time is up, stir to combine. There are many flavors of Boursin cheese, the Caramelized Onion is my favorite but the Garlic and Herb is also delicious.
