A good veggie burger should stick together without crumbling, fill your belly as a main course, and be packed full of flavor. These white bean burgers easily knock those requirements out of the park. Inspired by the aromatic flavors of Tuscany, each patty is seasoned with Italian herbs and features the umami-rich flavor of trumpet mushrooms. Cannellini beans, brown rice, carrots, green beans, and celery also make their way into the mix, ensuring each bite is bursting with healthy produce. (When cooking the patty mixture, the skillet needs to be wide to give a large surface for the liquid to cook off. If the mixture is too moist, you can spread it on a baking sheet and bake for 20 minutes at 300°F before shaping it into patties and baking again as directed in Steps 3–5.) Once the patties are out of the oven, assemble your sandwich on whole wheat buns and garnish with your favorite toppings and sauces. 


When shopping for burger buns, look for oil-free options that list 100 percent whole grains on the label. We recommend the whole grain buns from the Food for Life Ezekiel 4.9 product line.

Trumpet mushrooms are also known as king trumpet mushrooms, king oyster mushrooms, and French horn mushrooms.

Why trumpet mushrooms? Do they have a special flavor that stands out in this recipe? (They look cool). I’m cooking organic vegan food for a friend who is ill, and these were very pricey. Just trying to decide if they’re worth it for next time. I used too much seasoning, but otherwise the burgers are FANTASTIC! I can’t wait to make them again.

That is amazing burger


Left out the green beans and celery because I didn't have any. Added a can of kidney beans and a bunch more spices and these turned out pretty good. I don't know what trumpet mushrooms are but I just used the regular old white mushrooms you see in every grocery store. 350 for 37 minutes was perfect for me. I will be making again!


Reviewing this recipe for the first time, I think this maybe too much work. I would cut the recipe in half for six burgers. I would like to see the recipe list the cooked rice first so it’s ready before chopping all the veggies. The burgers sound delicious. I would make the recipe without forming into burgers. Thanks.

What can be substituted for trumpet mushrooms?

Jon Griffin

Yep. If you don't live in a large city, many things in these recipes aren't available. I would probably just substitute regular mushrooms.

Carol Miles

What can you substitute for trumpet mushrooms?

Lisa, Forks Over Knives Support

Hi Carol, If you don't have trumpet mushrooms (aka king trumpet mushroom, French horn mushroom, and king oyster mushrooms) you could substitute another type of mushroom such as portobello mushrooms. If you decide to try it, let us know how it goes!

Rena Konar

Do “trumpet mushrooms” have another name? I don’t believe I’ve ever seen them in regular grocery chains or HMart.

Lisa, Forks Over Knives Support

Hi Rena, Trumpet mushrooms are also known as king trumpet mushroom, French horn mushroom, and king oyster mushrooms. If you don't have any at your local store, you could substitue aother type of mushroom such as portobello mushrooms. This guide to mushrooms will give you an idea about the different types of mushrooms availabe in some supermarkets. https://www.forksoverknives.com/how-tos/mushrooms-types-how-to-use-them/

Meg Ross

These look delicious (I usually make black bean burgers), but even one half of a recipe is too much for just me. Can I bake them, wrap and freeze them, and heat one up when I want a burger for supper?

Lisa, Forks Over Knives Support

Hi Meg, Yes, veggie burgers freeze well. This is a great way to make easy meals for another day. Let us know how it goes! Thanks, Lisa Forks Over Knives, Support
