Heat the oven to 200°C (400°F). Boil potatoes in water for 18–20 minutes until tender, then drain.
Meanwhile, cook onion, carrot and mushrooms in half the oil for 10 minutes. Stir in flour, tomato paste and thyme for 1 minute.

Add stock, lentils, half the salt and pepper. Simmer for 8 minutes and transfer to an ovenproof dish.

Mash potatoes with oat milk, remaining oil and salt. Spread over the filling and rake with a fork. Bake for 20–25 minutes until the top is golden.
