This rich, sweet, and savory Vegan Caramelized Onion and Mushroom Grilled Cheese is an easy meal. Caramelized onions elevate grilled vegan cheese to another level!
Caramelized onions are one of those ingredients that elevates any dish you add them to. Pairing them with hearty baby portobellos and rich vegan Swiss cheese is the perfect combination of flavors.
This rich, sweet, and savory Vegan Caramelized Onion and Mushroom Grilled Cheese feels really indulgent. You may want to pair this with a glass of red wine.
Normally I like to use vegan cheddar or vegan cream cheese for a grilled cheese sandwich. Sometimes I'll use vegan Mozzarella or vegan jalapeño Havarti.
Using vegan Swiss cheese is a first for me. I was inspired to make this after making a Vegan Reuben and a Vegan Monte Cristo. They both needed Swiss to complete the recipe.
I've found that using the same ingredients several times in different recipes throughout the week is an extremely efficient way to work. It's great for using up ingredients where you want to change it up each time you make a meal.
This vegan grilled cheese is an indulgent meal.

It is Northern Bakehouse millet chia bread. I highly recommend it.

these look so good! I love that their vegan and use a dairy free cheese. I have been trying to limit my dairy in take!
a vegan and gluten free grilled cheese...yes please!!!!
I make the hubs vegan grilled cheese all the time. I use daiya mostly. I should try adding the shrooms though!

I used Daiya Swiss for this and really liked it. The caramelized onions and mushrooms really add a lot to the sandwich - you should try it!
I have been vegetarian for over a year now and feel SO GOOD and I am honestly really flirting with veganism. One thing I have not yet fully embraced is vegan cheese, though. I tried one brand once and I didn't like it at all. My friends who are vegan then told me that was the worse tasting one out there! I will have to give it another chance. This sandwich looks delicious!

I was a vegetarian for a year before going vegan. Cheese was hard for me to cut out also. But after I did I couldn't stand the smell in the deli section, and I can't stand the smell of butter - it is worse than smelling meat cooking. I would definitely try different brands of vegan cheese. I like Follow Your Heart and a couple of the Daiya vegan cheeses. I have yet to try other brands. You could also look into making your own. I make my own Tofu Feta and Tofu Ricotta and love them.
