Soak the Lentils: Rinse lentils thoroughly and place in a bowl. Cover with water and soak overnight or for at least 8 hours. Drain before using.
Preheat Oven and Prepare Pan: Preheat your oven to 180°C (350°F). Lightly grease a loaf pan or line it with parchment paper.
Blend the Batter: In a blender or food processor, combine the soaked and drained lentils, 100 ml water, olive oil, salt, ground coriander, and baking powder. Blend until the mixture becomes thick and mostly smooth.
Add Psyllium Husk: Pour the batter into a bowl and stir in the psyllium husk. Let the mixture sit for 10 minutes to allow the psyllium to absorb liquid and thicken the batter.
Shape and Top: Transfer the mixture to the prepared loaf pan. Use lightly oiled hands or a spatula to smooth the top. Sprinkle with black sesame seeds if desired.
Bake: Bake in the preheated oven for 45–50 minutes or until the top is firm and golden brown. A toothpick inserted in the center should come out clean.
Cool and Slice: Let the bread cool completely in the pan before slicing. This helps it firm up and hold its shape.
