Step 1

Preheat the oven to 375F and line a baking sheet with a silicone mat or parchment paper.

Step 2

Finely grate the beets using a food processor attachment or handheld grater. Set aside. Quickly clean out the processor, then re-attach it to the base with an S-blade attachment. Add the walnuts, oats, flax, garlic, all dry spices, and salt. Process until a slightly coarse flour forms.

Step 3

Add the shredded beets, beans, and tamari to the food processor and blend until combined, scraping the sides of the device with a spatula as necessary. It’s okay if there are still some pieces of beans or beets left – this will add texture!

Step 4

Scoop out the burger “batter” to form patties; I used a ½ cup measure to make 6 large patties. Use slightly damp hands to flatten and shape the burgers, then place on a baking tray.

Step 5

Bake in the middle rack of the oven for 20 minutes, then flip the burgers and bake in the top rack of the oven for 15-20 minutes, until the edges are crispy and slightly browned.

Step 6

Serve as desired; leftovers will keep in the fridge for up to 5 days, or can be frozen for up to two months
