• 240 ml (1 cup)half-and-half
• 57 g (4 tbsp)butter
• 7.5 ml (1½ tsp)salt
• to tastepepper

Instructions

1. 1

   Peel and cut

   Peel the potatoes and cut them into similarly sized pieces.

2. 2

   Boil the potatoes

   Put the potatoes in a large pot and cover them with water. Bring to the boil on the hob and cook for about 40 minutes, or until a fork passes through them very easily.

3. 3

   Drain the potatoes

   Drain the potatoes and transfer them to a large mixing bowl.

4. 4

   Mash until creamy

   Add the half-and-half, butter and salt, then beat with a hand mixer until creamy. Potato starchiness can vary, so add small amounts of extra half-and-half and butter if needed to reach the consistency you want.

5. 5

   Season to taste

   Taste and add more salt and pepper as desired.

6. 6

   Keep them warm

   Transfer the potatoes to a lightly buttered slow cooker, add a small knob of butter on top and set it to low. Stir from time to time until ready to serve.

What are make-ahead mashed potatoes?

Mashed potatoes are a familiar American side dish of cooked potatoes beaten with butter and dairy until smooth or fluffy. This version finishes in a slow cooker, which keeps the mash warm while the rest of the meal comes together.

Yukon Gold or another creamy potato gives the mash a naturally smooth texture. The half-and-half and butter enrich it, while the slow cooker makes serving timing more flexible.

Nutrition and macros by portion

The nutrition label shows one serving as written: 188 calories, 6g protein, 27g carbs, 6g fat.

The potatoes provide most of the carbohydrates, while butter and half-and-half contribute much of the fat; the small amount of protein comes mainly from the potatoes and dairy. Serve a portion with vegetables and a protein-rich main to round out the plate.

Choosing the potatoes

Creamy potatoes: Yukon Golds are suggested for their soft, buttery texture when mashed. Another similar variety works too.

Even pieces: Cut the peeled potatoes to a similar size so they soften at roughly the same pace. The fork test matters more than the clock: they should be very soft before draining.

Getting a smooth mash

Add the dairy and butter after draining, then beat with a hand mixer until creamy. The recipe notes that potato starchiness varies, so adjust with small additions of half-and-half and butter rather than adding a large amount at once.

Stop mixing once the texture is creamy. Season with extra salt and pepper only after tasting, since the salt added earlier already flavours the potatoes.

Using the slow cooker

Butter the slow-cooker insert lightly before transferring in the mash. The small knob of butter on top is part of the method and helps keep the surface rich as the potatoes wait.

Keep the cooker on low and stir occasionally. The recipe does not specify an exact holding time, so check the potatoes as they wait and serve once they are hot and ready.

Timing and doneness

The listed total time is 30 minutes, but the method calls for boiling the potatoes for about 40 minutes. Use the stated fork-softness cue to judge when they are cooked, and allow for that boiling time when planning the meal.

Cutting similarly sized pieces helps them cook evenly. If a fork meets resistance, continue boiling until the potatoes are very soft.

What to serve alongside

These potatoes suit a traditional roast dinner, where their creamy texture pairs well with roasted vegetables and a savoury main. They can also sit alongside a casserole or another comforting family meal.

For a more balanced plate, add vegetables and a protein-rich main rather than relying on the potatoes alone.

Recipe notes & tips

• Cut the potatoes into similarly sized pieces for even cooking.
• Wait until the potatoes are very soft before draining them.
• Add extra half-and-half and butter a little at a time, since potato starchiness can vary.
• Taste before adding more salt, then season with pepper as desired.
• Stir the potatoes occasionally while they stay on low in the slow cooker.

Variations

• Chunky texture: Mash the cooked potatoes less for a less uniform finish.
• Peppery finish: Add extra pepper to taste just before serving.
• Richer mash: Add small amounts of extra butter and half-and-half until the texture suits you.
• Different potato: Use another creamy potato variety in place of Yukon Gold.
• More seasoning: Adjust the salt after mixing, tasting as you go.

Common mistakes to avoid

• Uneven pieces: They may cook at different rates; cut the potatoes to similar sizes.
• Draining too soon: Firm centres are difficult to mash smoothly; boil until a fork passes through easily.
• Adding dairy all at once: The mash may become looser than intended; add any extra in small amounts.
• Overmixing: The potatoes can lose their fluffy character; stop once they are creamy.
• Forgetting to stir: The mash can sit unevenly in the cooker; stir occasionally while it stays on low.

How to store

Refrigerate leftovers in a covered container once cooled, and use within 3–4 days. Reheat until piping hot, stirring in a little half-and-half if needed to loosen the texture; avoid leaving the potatoes at room temperature for an extended period.
