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.
- The Cashew mozzarella uses cashews, olive oil, garlic miso, lemon juice and flour or starch for thickening. No nutritional yeast!
- 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.

Love these! Thanks for the recipe. The miso in the cashew cream works really well.
Autocorrect nightmare! Miso! I meant miso!
😀 😀 😀
Hello! What water temperature do you recommend soaking the cashews at? E.g. boiling water or hot water from the sink? And is there any way to speed up the soaking process?
soak in boiling water for 15 mins. thats enough. Often i dont even soak and just blend them. blend them for a minute then let themixture (which will look gritty) rest for 5 mins. Then blend again. It gets creamy and any small gritty ness will cook out
I made these tonight and they were great! I added nutritional yeast to the cashew cream (because I love it!) and some chili flakes to the mushroom mix (because I love them!) and so enjoyed this recipe. Thank you!
awesome
