Labor Day Celebration! – Mushroom Veggie Burger

Burgers are a staple of many Labor Day celebrations, including ours. Sometimes we do beef burgers (there’s a number of them on this blog), and sometimes turkey burgers. We’ve even done bison burgers. I’ve wanted to add a vegetarian option to our repertoire for a while now, and I finally found the perfect recipe!

We’ve experimented with a number of different black bean burger recipes, but none of them thrilled us. I think Eric might have actually sighed deeply when I suggested we try yet another meatless burger recipe a few weeks ago. I assured him that this one was very different from the others and after reading through the ingredient list and directions, he agreed to try it.

These meatless burgers have a umami-rich flavor and a hearty texture. They hold together well on the grill but can also be cooked on the stove. They are tangy and smoky, along with being savory. Freshly cooked brown rice brings the stickiness to the mixture that holds the mushrooms, panko, and flaxseed together. Walnuts contribute an additional meaty bite. A hint of smokiness and spice comes from the smoked paprika and sriracha added into the mix. Garlic and shallots round out the depth of the flavor profile. These meatless patties wonderfully expand our recipe collection in the burger department!
