Easy Vegan Mushroom Quesadilla with Cashew Mozzarella. These Spinach mushroom quesadillas have a delicious caramelized mushroom filling and gooey cashew mozzarella! Add beans for a hearty meal. Vegan Recipe, Easily Gluten-free, Soyfree. Jump to Recipe

I am back with my favorite flavors in the nicely golden mushrooms with some onion and spinach, and then layered with creamy mozzarella, and grilled to perfection in a quesadilla.
The onions and mushrooms are cooked to golden, then flavored with balsamic, soy sauce and garlic and simmered to make a delicious filling. Spinach is folded in the end. The cashew mozzarella is more of a thick cheesy cream sauce that is spread on the tortilla. The thick sauce melts or thins out when heated and then thickens again on cooling, holding the ingredients of the quesadilla. Since we are not making a solid vegan mozzarella, no chilling and waiting is needed. You can also convert this into a melt sandwich. Add layers of the mozzarella cream to the slices, fill with the mushroom filling and grill. Yuhm!

Ingredients for Cheesy Vegan Mushroom Quesadilla and substitutions
- You will need 2 large tortillas. Use gluten-free if needed, or use my gluten-free flatbreads
- For the mushroom spinach mixture,sliced onions and mushrooms and spinach form the base.
- Soy sauce, balsamic, vegan worcestershire and garlic add deep umami flavor.

- Gluten-free: use my gluten-free flatbreads
- Nut-free: Try my Cauliflower alfredo or pumpkin seed alfredo or my nut-free nacho cheese instead of the cashew mozzarella.
- Soy-free: Use coconut aminos instead of soy sauce and red wine instead of worcestershire. Use chickpea miso in the mozzarella cream.

I made this today. Yummy! My hubs told me he’d been missing quesadillas a lot. I’ve seen other vegan quesadilla recipes from other bloggers, of course, but was never moved to try them. I knew I could trust your recipe to be delicious.
I skipped the oil by water sautéing the vegetables. I didn’t have spinach so I added an orange and a red pepper, and also a zucchini, and doubled the spices. I now have enough vegetables for a few more batches. 🙂
Thank you for the recipe!
Awesome!Thanks!!
These we’re surprisingly easy to whip up and soooo tasty, I couldn’t stop eating them! Make sure to make an extra big batch 😋
Awesome! yes definitely double it!
Quick & easy to make & sooo delicious! Richa, you are the best! (I made them without the spinach).
awesome! Thanks!
Loved it! Thanks Richa. 🙂
awesome! long time!
Made these Monday night and ate ALL the leftovers for yesterday’s lunch, just crisped up in the office toaster oven. There were absolutely delicious and the mozza sauce was AMAZING! This one is going into rotation for sure, thanks for the great recipe.
yay!!
This is AMAZING im not a very savy cook and this was easy to make, quick and SOOO delicious!! Thank you so much!
yay!! Thanks!
This sounds fabulous, cannot wait to try it! I have two questions:
1. If using tapioca starch, do you omit the flour?
2. Is the olive oil necessary? Sometimes I blend in a couple olives instead, do you think that would work here? Thank you so very much!
its in addition tothe flour. the cheese will be thicker and melt more during grilling.
You can omit the oil, dont use olives, they are a different flavor
I made this for dinner tonight. Wow! Love the creamy, gooey mozzarella. This will definitely be making repeat appearances on the menu at our house!
Yay!!
1. Made this today and it was fantastic!
2. I think it’s cute that you thought there would be leftovers 😋
😀
Wow, these look amazing! What a great idea to use a spreadable cashew-based cheese. I can’t wait to try these. Thanks for sharing!
thanks!
Can the miso be left out?
yes
