Ingredients
 

For the casserole

  • 1 ½ cup (300 g) red lentils
  • 14 ounces (400 g) canned coconut milk
  • ½ cup (65 g) chickpea flour
  • 2 tablespoons curry powder
  • ½ teaspoon garlic powder
  • ¼ teaspoon salt
  • teaspoon pepper

For the potatoes

  • 1 yellow onion
  • 6 medium potatoes
  • Olive oil
  • Salt to taste

Instructions
 

  • Soak the red lentils in warm water while you prepare the filling.

For the potatoes

  • Peel and dice the onion. Peel the potatoes, cut them in half, and into ⅛" (3 mm) thick slices.
  • Heat a skillet with a generous amount of olive oil. Sauté the onion over medium-high heat for 2-3 minutes stirring often.
  • Add in the potatoes and cook over medium heat for 12 minutes, stirring regularly.

For the casserole

  • Preheat the oven to 400°F (200°C).
  • Drain and rinse the lentils. Add them to a high-speed blender with the coconut milk, chickpea flour, curry powder, garlic powder, salt, and pepper. Blend for 1-2 minutes until smooth.
  • Add the potatoes to a lightly greased casserole dish. Pour the lentil mixture on top. Give it a good mix to make sure everything is well combined and spread it out evenly.
  • Bake for 35 minutes at 400°F (200°C) fan.
