    Mushroom Veggie Burger Recipe Tips and Variations

    Tip! The mixture for the veggie burgers will be mushy and fragile. It’s important to form them while they mixture is cold. If you are in a hurry, place them in the freezer for about 15 minutes.

    Change up the vegetables and use any combination of shredded zucchini, butternut squash, sweet potatoes and beets

    Vegan Version – This recipe is vegetarian, and you can easily transform it to a vegan recipe by using a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) in place of an egg and replace the parmesan cheese with ⅛ cup nutritional yeast.

    Serving Suggestions

    Serve your mushroom veggie burgers on a bed of field greens or between a whole grain roll with a side of kale Caesar salad.

    Storing and Freezing Homemade Veggie Burgers

    Store leftover vegetarian mushroom burgers in an airtight container in the refrigerator for up to three days.

    Freeze unused cooked veggie burgers by placing them onto a parchment-lined baking sheet and placing it into the freezer. Once the burgers are frozen, remove them from the cooking sheet and place them into an airtight container for up to three months. No need to thaw the burgers, simply reheat them from frozen.

    Reheat leftover veggie burgers on top of the stove over medium heat.

    Freezing uncooked burgers is not recommended.

          I’ve tried using.m a portobello mushroom alone for a meat in a burger and wasn’t a fan. I love how you combined all this extra flavor to make a patty. I can’t want to give this a try it looks amazing!
