Yes, almond flour is a good substitute for bread crumbs. You can also try and mix almond flour and almond meal (50/50). The combination will help to bind the patties well and give you a similar crispy texture that you’ll get when frying the patties with panko breadcrumbs.
Start using the same amount of almond flour as Panko and adjust it upwards if necessary. You’re probably aware of it, but the taste will change slightly because Panko breadcrumbs have a neutral flavor, whereas almond flour/almond meal has a distinct nutty flavor. That’s not necessarily bad, just something to be aware of. Hope that helps.
