These crispy smashed potatoes are golden and crunchy on the outside with soft fluffy centres, finished with garlic butter and sea salt. They look impressive but are incredibly easy!

Some potato recipes are all about fluffy centres, while others are all about crisp, golden edges. Smashed potatoes give you both.

Boiling the potatoes first keeps the middles soft and creamy, while flattening them creates lots of craggy edges that turn beautifully crisp in a hot oven.

I finish mine with melted garlic butter halfway through roasting rather than at the beginning. It's a small step that makes a noticeable difference because the garlic stays fragrant instead of catching in the oven.

A final sprinkle of flaky sea salt is all they need before serving alongside everything from roast chicken and steak to grilled fish or a simple salad.

Smashed potatoes aren't tied to one traditional cuisine. They've become popular because they take familiar roast potatoes and make them crispier with very little extra effort.

You'll find versions topped with Parmesan, herbs, chilli crisp and everything from sour cream to chimichurri, but I keep coming back to this simple garlic butter version because it works with almost any meal.

This recipe suits almost every occasion. I serve these potatoes alongside roast chicken, grilled lamb chops, barbecue food, baked fish or even a simple fried egg for lunch.

They also make an excellent addition to a buffet because they're just as enjoyable served warm as they are at room temperature.

Although the ingredients couldn't be simpler, taking a few extra moments to dry the potatoes well after boiling and giving them enough space on the tray makes all the difference.

Crowded potatoes steam instead of roast, and that's the easiest way to lose those beautifully crisp edges.

Baby Potatoes

Baby potatoes are ideal for smashed potatoes because their thin skins become wonderfully crisp while the small size means they cook evenly.

Their naturally creamy texture also holds together well after boiling, making them easy to flatten without completely falling apart.

Choosing potatoes that are similar in size helps every one finish roasting at the same time.

  • It pairs effortlessly with meat, fish and vegetarian mains.
  • The recipe is easy to adapt with herbs, cheese or spices.
  • Leftovers reheat surprisingly well and stay crisp in the oven.
  • It's simple enough for a weekday meal yet impressive enough for guests.

Ingredients

You only need simple pantry ingredients for this recipe!

  • Baby potatoes. Choose potatoes that are similar in size so they cook evenly and are ready to smash at the same time. Baby white, baby red, or Yukon Gold potatoes all work well because they hold together while still becoming fluffy inside.
  • Butter. Melted butter adds richness and helps carry the garlic flavour over every potato. If you prefer, you can swap it for a plant-based butter without changing the cooking method.
  • Garlic. Freshly minced garlic gives the best flavour and aroma. I add it after the potatoes have started roasting so it becomes lightly toasted rather than burnt, which keeps the flavour sweet and mellow.
  • Olive oil. A drizzle of olive oil encourages the potatoes to brown evenly and develop those crisp, crunchy edges. A neutral oil such as avocado or vegetable oil can be used if that's what you have.
  • Sea salt. Good sea salt is one of the simplest ways to lift the finished dish. I like using flaky sea salt for serving because it adds little bursts of crunch, but fine sea salt works perfectly during cooking too.

Recipe Tips

  • Dry the potatoes thoroughly after boiling. Less moisture means crispier roasting.
  • Avoid over-boiling. The potatoes should be tender but still hold their shape.
  • Smash gently rather than flattening completely.
  • Thicker potatoes stay fluffy inside.
  • Leave space between each potato on the baking tray.
  • Air circulation helps every edge crisp.
  • Add the garlic after the first roast to stop it burning.
  • Roast until deeply golden rather than simply lightly coloured.
  • Much of the flavour develops during those final minutes.
  • Use a sturdy glass or potato masher if a fork feels awkward.
  • Serve immediately for the crispiest texture.

FAQs

Why aren't my smashed potatoes crispy?

They're usually too wet or too crowded on the baking tray. Drying them thoroughly and leaving space between each potato helps them roast instead of steam.

Which potatoes work best?

Baby potatoes or waxy new potatoes give the best combination of creamy centres and crisp skins.

Can I make smashed potatoes in an air fryer?

Yes. Cook them at a high temperature until crisp, turning once if needed for even colouring.

Should I peel the potatoes?

No. The skins become deliciously crisp and help hold the potatoes together during roasting.
