Mushroom & Caramelized Onion Grilled Cheese

Posted on August 22, 2013
Hi Everyone! If you’re a grilled cheese lover like I am, you will love this Mushroom & Caramelized Onion Grilled Cheese! Of course there’s nothing wrong with a regular grilled cheese sandwich, but if you want to make it just a little more special and extra delicious, this is my favorite way to do it! The combination of the meaty mushrooms, sweet caramelized onions and gooey cheese all melting together in between two slices of fresh sourdough bread is hard to beat and makes for a great lunch or side to a big bowl of soup!
Fresh sourdough bread
Olive oil
To make your sandwich, begin by sauteing your mushrooms in some olive oil and a little bit of butter. Once the mushrooms have some nice color and are softened, take them out and set them aside, and cook your onions until they are translucent and soft (you can add a sprinkle of sugar if you want them a little sweeter). Once they are done, you can start assembling your sandwich: butter each of your sourdough bread slices and stuff your sandwich with the mushrooms, onions and cheese. Cook on medium heat for a couple of minutes on each side until the bread is golden brown and the cheese has melted. Let sit for about a minute until slicing.
Happy Cooking, Everyone!

    Grilled cheese is one of my favorite foods on this earth. Favorite I tell you. In college there was a bar & grill right next to my room that i visited at least once a week. I walk in and they already knew I was gonna order two grilled cheeses with a side of fires. I will deff be making this sometime soon. Thanks for sharing and thanks for linking up with us at the TGIF link up.

    Yum…I don’t even like onions and this looks delicious! But my family does, so I’ll have to make this for them sometime and just use the mushrooms on my sandwich… 🙂 Hopping over from Show Stopper Saturday to say thanks for the inspiration!

    Looks great – whenever I slice onions I save a few slices for caramelizing for my sandwiches! But adding mushrooms is just genius! Julia
