Step 1: If using an electric AGA, start by turning on your roasting oven to R6. If using a traditional aga, you will be using the roasting oven for this recipe.

Step 2: Peel the sweet potatoes, chop them up and place on a lined roasting tray. Drizzle with olive oil and season with a generous pinch of salt. Cook for around 45 minutes.

Step 3: Chop the mushrooms. Slice them lengthway and then turn the mushroom around and slice in the opposite direction, until each mushroom is chopped into 10-12 small pieces. Mince the red onion.

Step 4: On the AGA add a frying pan and a splash of Olive Oil. Start by cooking the red onion, stirring until browned and softened. Transfer the onions to a bowl and leave to cool. In the same pan add the mushrooms and a further drizzle of olive oil, stir over a high heat until well cooked. Add in 2 cloves of crushed garlic for the final few minutes. Take off the heat.

Step 5: Once the sweet potatoes are cooked, place to the side to let cool. Once cool add into a food processor with the black beans, and spices: cumin, oregano and chilli powder. Blend until it starts to smooth, stopping before it’s a complete puree and still has some texture. Spoon the mixture into a bowl.

Step 6: Make the oatcake breadcrumbs. Add the oatcakes into a blender and blend until it’s a breadcrumb consistency. Pour into the mixing bowl with the burger mix and combine well using your hands. 

Step 7: Shape the mix into approx 8 burgers. Add a touch of olive oil to your pan and cook the burgers for 3 minutes on each side. Place on a baking tray and into the AGA for 10-15 minutes as you complete the rest of the burgers. 

Step 8: While the Burgers are in the oven let’s make the Harissa sauce. Add all of the ingredients into your blender and blend until smooth.

Step 9: To compile the burgers, get your favourite burger bun and fillers (tomatoes, lettuce, avocado etc). Add the burger into your bun, stack with your favourite toppings and a spoonful of our harissa sauce. Serve up!
