Vegan Stamppot with Lentils and Mushrooms (Dutch Potato Mash)
Why this recipe works
- Hearty and satisfying: Floury potatoes create the soft, filling base expected from stamppot, while lentils add substance without needing meat.
- Deep savoury flavour: Browning the mushrooms before folding them into the mash brings earthy depth and balances the sharpness of the Dijon mustard.
- Creamy without dairy: Hot vegetable stock and olive oil loosen the mash and give it a smooth, rounded finish while keeping the recipe fully vegan.

Authenticity notes
- Dutch comfort food: Stamppot is a Dutch mashed potato dish typically served as a simple, filling meal, often with vegetables mixed directly into the mash.
- Vegan adaptation: Lentils and browned mushrooms replace the more traditional meat accompaniments, keeping the dish hearty while adding plant-based savouriness.
Ingredient notes
- Choose floury potatoes: Russet or another floury potato gives the mash a lighter, fluffier texture than waxy varieties.
- Drain the lentils well: Excess cooking water can loosen the mash too much, so let the lentils drain thoroughly before folding them through.
- Mustard matters: Dijon gives a smooth tang; whole-grain mustard can be used for a gentler flavour and more texture.
Texture tips
- Steam-dry the potatoes: Returning the drained potatoes to the hot pot briefly helps moisture evaporate, giving the mash a lighter finish.
- Add stock gradually if needed: The mash should be creamy rather than loose, so adjust the hot stock carefully depending on the potatoes.
Make-ahead tips
- Good for meal prep: The finished stamppot keeps well in the fridge and can be portioned for easy lunches or dinners.
- Reheat gently: Warm in a saucepan over a low heat with a splash of vegetable stock, stirring until piping hot and creamy again.
- Freezes well: Freeze in portions, then defrost overnight in the fridge before reheating gently.

Ingredients
Instructions
- Peel the potatoes and cut into even chunks. Rinse the lentils well. Finely chop the onion, slice the mushrooms, and thinly slice the spring onions.
- Put the potatoes in a large pot, cover with cold water, and add 1 tsp of the salt. Bring to the boil, then simmer for 15 to 18 minutes until very tender. Drain well in a colander and return the potatoes to the hot pot to steam-dry for 1 minute.
- Meanwhile, cook the lentils in a separate pot of simmering water for 18 to 22 minutes until tender but not mushy. Drain well and set aside. If they are done early, cover to keep warm.
- Heat 2 tbsp of the olive oil in a large frying pan over a medium-high heat. Add the onion with the remaining 1 tsp salt and cook for 4 to 5 minutes until softened. Add the mushrooms and cook for 6 to 8 minutes until their liquid has evaporated and they are well browned.
- Mash the potatoes until smooth, then stir in the hot vegetable stock, Dijon mustard, black pepper, and the remaining 1 tbsp olive oil. Fold in the lentils and the mushroom mixture, then cook over a low heat for 2 to 3 minutes, stirring, until piping hot. Stir through most of the spring onion, reserving a little to finish.
- Taste and adjust with a little more salt or pepper if needed. Spoon into bowls and scatter over the reserved spring onion. Serve straight away while hot and creamy.
Recipe notes
Tips
- For the best texture, let the drained potatoes steam-dry in the hot pot before mashing so the stamppot stays fluffy rather than watery.
- Brown the mushrooms until their moisture has cooked off and they take on colour; this is where most of the savoury depth comes from.
- If serving anyone who is sensitive to mustard, keep the Dijon mustard to the side and stir it into individual portions instead.
Substitutions
- Replace Dijon mustard with whole-grain mustard for a milder heat and a coarser texture.
- Replace mushrooms with oyster mushrooms for a meatier bite.
Storage
- Refrigerate up to 3 days
- Cool quickly, then refrigerate in a sealed container for up to 3 days. Freeze in portions for up to 2 months; defrost overnight in the fridge and reheat in a saucepan over a low heat with a splash of vegetable stock, stirring until piping hot.
