What you will need
This recipe uses 6 simple ingredients that you can find at any grocery store:
- 400 g brown lentils drained and rinsed
- 350 g chestnut mushrooms diced
- 1 kg potatoes peeled and cubed
- 2 tbsp tomato paste
- 0.5 cup milk warmed
- 2 tbsp butter
Step by step instructions
Step 1: Make the Mashed Potato Topping
Boil the cubed potatoes in salted water for 15 minutes until completely tender when pierced with a fork. Drain and mash with the warmed milk and butter until smooth and creamy, then set aside.
Step 2: Cook the Mushroom Lentil Filling
Heat oil in a large ovenproof skillet over medium heat and cook diced mushrooms for 8 minutes until deeply browned. Add the tomato paste and stir for 1 minute, then add the drained lentils and 1 cup of vegetable broth.
Step 3: Simmer and Season
Stir the filling mixture and simmer over low heat for 10 minutes until thickened, seasoning generously with salt, pepper, and a pinch of dried thyme. The mixture should be saucy but not watery.
Step 4: Assemble and Bake
Preheat the oven to 190 degrees Celsius and spread the mashed potato over the mushroom lentil filling in an even layer, using a fork to create texture on top. Bake for 20 minutes until the top is golden and the filling is bubbling around the edges.

- brown lentils → green lentils or canned lentils to save time
- chestnut mushrooms → portobello mushrooms for a meatier bite
Common mistakes to avoid
Watch out for these pitfalls that can affect your results:
- Making the lentil filling too wet which causes the mashed potato topping to sink into it
- Not browning the mushrooms long enough which results in a bland filling without depth
