Step 1

Rinse the kidney beans and give them a good shake to remove any excess water.

Step 2

Scoop up about half of the beans into a small container and set aside. Add the remaining half to a food processor.

Step 3

To the food processor also add the onion, garlic, ketchup, oregano, chili powder/smoked paprika, salt and pepper then process to a paste. Scrape down as needed to make sure everything is blended.

Step 4

Open the food processor and add the remaining kidney beans, oats and parsley if using. Pulse to combine, breaking up the oats and beans into smaller but still chunky pieces. You will need to get in there and give it a scrape down the sides and into the bottom to make sure everything combines well. Don't process it too much or you will lose the texture.

Step 5

Have a plate or small baking tray lined with parchment paper next to you.

Step 6

Remove the blade from the food processor and shape the mixture into four ½ to ¾ inch thick patties. Prior to shaping each patty, really squeeze the mixture together in a tight ball in your hand to compact everything. This helps them hold their shape.

Step 7

Lay the patties out onto the lined plate or tray once shaped. Refrigerate for at least 20 minutes but up to 3 days is ok. If only chilling for about half an hour there is no need to cover them. Any longer cover the plate/tray well so the patties don't dry out.

Step 8

Brush a large skillet or frying pan with a little oil and place over medium-low heat. Once the pan is hot, carefully add the burger patties. Cook for about 8 minutes on each side or until firm and brown on both sides. Time will vary slightly depending on your cookware and stove top so use your judgment and cook a little longer/less if necessary.

Step 9

Put the burgers on a lined baking tray and bake them in the oven on 375°F (190°C) for about 20 to 25 minutes, or until heated through and crusty on the outside. Flip them over halfway through the cooking time.

Step 10

I don't recommend putting these burgers right onto the grill grates. Instead either place on greased aluminum foil on the grill to give them some support, or use a greased grill pan or cast-iron skillet. Cook them over medium-low heat for about 7 to 8 minutes each side or until brown and firm.
