Vegan Black Bean Burger with Brussels Sprouts

Are you craving a real good vegan burger with a luscious black bean patty and a super creamy sweet potato sauce. Here we go! Today I’ll show you how to make a “Winter season burger” with Brussels sprouts and the best cheese substitute you can imagine. Don’t worry, the recipe looks very extensive, but that’s because I’ll also show you how to make your own burger buns. Vegan burger buns are super easy to make but of course you can skip making them and go for ready made buns. Also, the preparation time is shorter than indicated, because most of the working steps can be done in parallel.  So, while the dough for the burger buns is resting, you can already prepare the patties and other ingredients.

Hope you enjoy your burgers and don’t forget to let me know your thoughts on this recipe. Looking forward to your feedback, all the best Lea.

Other ingredients (can be varied individually)

  • 250 g (8.8 oz) Brussels sprouts
  • 1 tbsp. olive oil
  • 1 tsp. cumin
  • Optional: 1-2 tsp. agave syrup

  • For the burger buns, mix flour and salt in a bowl. Add dry yeast and 120 ml (0,7 cups) lukewarm water and mix. Leave to swell for about 3 minutes. Then add a pinch coconut sugar and olive oil and knead a smooth dough on a floured work surface.
  • Cover the dough and let it sit for 45-60 minutes. Divide the dough into 4 parts, knead intobuns, place on a baking tray covered with baking paper, brush with plantbased milk, sprinkle with sesame seeds (and press them lightly into the dough) and let the buns sit for another 10-15 minutes.
  • Bake your buns at 220°C/428 °F  in a preheated oven for 10-15 minutes. After half the baking time, brush the buns again lightly with plantbased milk (this will give them a nice golden color).
  • For the burger patties: Mix the ground flax seeds with 3 tbsp. water and let it swell. Peel onion and garlic clove and dice finely. Clean the mushrooms, shorten the stems and chop finely. Rinse the beans.
  • Heat 1 tbsp oil in a pan. Fry the onion, garlic and mushroom cubes for 3-4 minutes and season with herbs the Provence and a pinch of salt.
  • Pulse the black beans with the oatmeal in your blender, add the fried mushroom cubes, the flax egg, 1-2 tsp miso paste, 2 tbsp tomato paste and the spices and pulse again (don't overdo the blending!).
  • Remove patty dough from the blender and place it in a bowl. Mix it with 3-4 tbsp. breadcrumbs or 3-4 tbsp. chickpea flour for a gluten-free version, until the dough is easy to shape. Add chopped parsley and form 6 patties with slightly moistened hands. Important: Press the patties flat and don't let them get too thick, otherwise they won't fry well inside. 
  • Fry the patties in a pan with plenty of vegetable oil on both sides for 3-4 minutes. It is better to fry them at medium heat for a little longer than short and too hot, otherwise they will quickly darken on the outside and are not yet well fried on the inside. So, medium heat 3-4 minutes per side. Keep them warm in the oven.
  • Wash Brussels sprouts, cut into fine slices, mix with 1 tablespoon olive oil, cumin, a pinch of salt and 1 tsp.n agave syrup and place on baking paper. Wash half a sweet potato, cut into (thin) slices and place on the baking tray without adding any more fat.
  • Bake Brussels sprouts and sweet potatoes at 180 °C/ 356 °F. After 10 minutes baking time, remove the Brussels sprouts from the parchment paper, salt again and keep baking the sweet potato slices for another 4-5 minutes until they are completely soft.
  • For the "sweet potato cheese substitute": Puree the soft sweet potatoes with 1 tbsp. almond paste, 3 tbsp. yeast flakes, a pinch of salt, chilli flakes as desired, 1 tsp. paprika powder and a pinch of garlic powder (or add half a clove of garlic) and 4-5 tablespoons plantbased milk in a blender. Add more almond paste and plantbased milk for even more creaminess. Season to taste with salt.
  • Slice open the buns, spread with sweet potato cream, layer with Brussels sprouts and the patties, optionally drizzle with Sriracha and enjoy.
