• Preheat your oven to 180°C.
  • Slice the potatoes in big chunks and add them to a liter of boiling water. Let it cook for 30min.
  • Meanwhile, let’s make the cream corn: in a large skillet, melt the butter over medium-high heat.
  • Sprinkle with flour and cook for 30 seconds, stirring. Add the cream, stirring constantly, then add the corn kernels and bring to a boil.
  • Reduce heat to low and simmer, stirring occasionally, for 10 to 12 minutes or until corn is tender. Add salt and pepper.
  • Use a hand blender to turn the corn mixture into a coarse puree.
  • Once the potatoes are cooked, add the milk and use the blender to turn them into puree.
  • Cook the brown lentils in boiling water for 25min.
  • Meanwhile, slice the onion, garlic and mushrooms.
  • In a pan, heat the oil over medium heat and stir-fry the onion, garlic and mushrooms for about 5 minutes.
  • Slowly add the lentils, walnuts, thyme, soy sauce, tomato paste and maple syrup. Mix well and transfer the mixture to a baking dish.
  • Place the corn on the lentil mixture and cover with mashed potatoes.
  • If you want, you can cover everything with shredded cheese.
  • Bake for about 25 minutes, and broil for 5min if you added the cheese.
