Instructions

1. 1

   Roast the garlic

   Heat the oven to 220°C (425°F). Slice off the top of the garlic head to expose the cloves, drizzle with olive oil and wrap in foil. Bake until soft and golden, about 40 minutes. Remove from the oven and, once cool enough to handle, squeeze the cloves into a bowl and set aside.

2. 2

   Boil the potatoes

   Put the potatoes in a large pot and add enough water to cover them, along with about 2 tablespoons of salt. Bring to the boil, then reduce the heat and simmer uncovered for about 10–12 minutes, until the potatoes fall apart easily when pierced with a fork.

3. 3

   Drain the potatoes

   As soon as the potatoes are tender, drain them in a colander.

4. 4

   Mash until smooth

   Transfer the hot potatoes to a mixing bowl and mix with a paddle attachment until smooth, about 1 minute.

5. 5

   Mix in flavourings

   Slowly add the roasted garlic, miso, butter and milk. Gradually increase the mixer speed and mix for 1 minute longer.

6. 6

   Whip until fluffy

   Change to the whipping attachment and beat for about 1 minute, or until fluffy.

7. 7

   Season the mash

   Season with salt and pepper to taste.

8. 8

   Garnish and serve

   Serve warm, topped with extra butter if desired and the chopped chives.

What are miso mashed potatoes?

Mashed potatoes are a familiar American side dish, made by cooking potatoes until tender and mashing them with rich additions. This version brings in white miso, a Japanese fermented soybean paste, for a savoury depth alongside the mellow sweetness of roasted garlic.

The combination works because butter and milk soften the miso’s salty, concentrated flavour, while chives add a fresh note at the end.

Nutrition and macros by portion

The nutrition label shows one serving as written: 252 calories, 1g protein, 2g carbs, 5g fat.

The potatoes provide most of the carbohydrates, while butter and milk contribute much of the fat; miso adds savoury flavour and some protein. Pair a serving with a protein-rich main and vegetables for a more balanced plate.

Choose potatoes that mash well

Potato choice: Floury or all-purpose potatoes tend to break down readily and make a soft mash. Cut them into similarly sized cubes so they cook at a similar pace.

Peeling: The recipe leaves peeling optional. Peeled potatoes make a smoother result; leaving the skins on gives the mash a more rustic texture.

Roast the garlic until soft

Garlic: Roasting the whole head mellows its sharpness and makes the cloves easy to squeeze out. The cloves should feel soft, with golden edges, before you use them.

Timing: The stated roasting time is about 40 minutes, even though the listed total time is 25 minutes. Allow for the longer oven time, or roast the garlic ahead.

Cook and drain the potatoes well

Water: Start with enough to cover the cubes and bring it to a boil before lowering the heat to a simmer. Keep the pot uncovered as directed.

Doneness: The potatoes are ready when a fork pierces them easily and they begin to fall apart. Drain them promptly so they do not sit in excess cooking water.

Mix for a smooth, fluffy texture

Paddle: Mixing the hot, drained potatoes with a paddle for about 1 minute breaks them down into a smooth base. Add the garlic, miso, butter and milk gradually, then mix for 1 minute longer.

Whisk: Finish with the whipping attachment for about 1 minute, stopping once the mash is fluffy. Avoid prolonged mixing, which can make potatoes gluey.

Balance the miso and serve

Miso: White miso brings both saltiness and savoury flavour, so taste before adding more salt. The recipe also salts the potato water, making the final seasoning check especially useful.

Serving: Chives provide a bright contrast, while a little extra butter is optional. These potatoes pair well with roasted vegetables, fish or a main dish with savoury pan juices.

Recipe notes & tips

• Roast the garlic ahead of time to make the final preparation quicker.
• Cut the potatoes into evenly sized cubes for more consistent cooking.
• Drain the potatoes as soon as they are tender.
• Add the miso gradually and taste before increasing the salt.
• Stop mixing when the potatoes are fluffy to help avoid a gluey texture.

Variations

• Extra chives: Scatter more finely chopped chives over the mash just before serving.
• More roasted garlic: Add extra roasted cloves for a stronger, sweeter garlic flavour.
• Miso adjustment: Start with less miso and add more gradually to suit its saltiness.
• Skin-on mash: Leave the potato skins on for a more rustic finish.
• Dairy-free option: Use plant-based butter and milk in place of the dairy ingredients.

Common mistakes to avoid

• Undercooked potatoes: Keep simmering until a fork passes through easily.
• Watery mash: Drain the potatoes thoroughly as soon as they are tender.
• Too much salt: Taste after adding miso, since the potato water and paste are both salty.
• Gluey texture: Mix only until smooth and fluffy rather than beating for longer.
• Rushing the garlic: Allow about 40 minutes for roasting, or prepare it in advance.

How to store

Refrigerate leftovers in a covered container for up to 3 days. Reheat gently in a saucepan or microwave, stirring in a small splash of milk if the mash seems dry.
