Veggie burgers fail for one of two reasons: they fall apart on the grill, or they taste like damp cardboard. The sweet potato and cannellini bean version avoids both, but only if you follow the instructions about chilling. Skipping the refrigeration step is where people go wrong. Sixty minutes minimum in the fridge, and the patties will hold. The garam masala here is doing real work, not just flavoring but pulling the mixture together in a way that bland versions miss. Serve these on a sturdy bun with yogurt sauce or harissa, not ketchup.
How to Make Sweet Potato Veggie Burger
Chill the patties, both times
Refrigerate the mixture before forming patties, and refrigerate the shaped patties again before cooking. Both steps are essential if you want them to survive the pan. A warm patty hits a hot surface and immediately starts losing shape. Cold patties hold.
Getting the moisture right
Sweet potatoes hold a lot of water. Bake yours until very well done and let them cool uncovered so steam escapes. A wet sweet potato will throw off the whole ratio of the mixture and no amount of extra breadcrumbs will fully compensate. 
Cooking method
A cast-iron or non-stick pan at medium heat gives a better crust than a regular skillet. Don’t move the patties for the first three minutes. Let the surface set before you try to flip, otherwise they crack. Two flips total, that’s all they need.

Frequently Asked Questions
Can I bake these instead of grilling them?
Yes. Place the patties on a lined baking sheet and bake at 375F for about 20 minutes, flipping halfway through. They won’t get grill marks, but they’ll hold together well and develop a nice crust.
Why do the patties need to be refrigerated twice?
The first chill firms up the mixture so you can shape it. The second chill after shaping helps the patties hold their form on the grill. Rushing this step is the most common reason veggie burgers fall apart.
Can I substitute the all-purpose flour to make these gluten free?
Use chickpea flour or oat flour as a 1:1 replacement, and swap the panko for gluten-free breadcrumbs. The patties will still bind properly.
