Notes & Wine Advice
Serving Suggestions
Serve the potatoes alongside grilled vegetables, burgers, roasted meat, or fish. They also make a satisfying snack when accompanied by garlic mayonnaise, mustard dip, or vegan sour cream.Recipe Notes
Choose small potatoes of a similar size so they cook evenly. They must become completely tender before smashing or they may split apart. Leave space between the potatoes in the air-fryer basket so the exposed edges can become crisp.Variations
Replace rosemary with thyme, oregano, or sage. Add smoked paprika, black pepper, or chilli flakes before air-frying. Apple cider vinegar can replace white vinegar for a slightly milder and fruitier flavour.Storage
Store leftover potatoes in an airtight container in the refrigerator for up to three days. Reheat them in the air fryer at 190°C (375°F) for 5 to 8 minutes. Freezing is not recommended because the potato centres may become watery.Wine Advice
A crisp Sauvignon Blanc complements the sharp vinegar and aromatic rosemary. A dry Riesling is another refreshing choice.Nutrition values

Vinegar smashed potatoes combine a fluffy centre with crisp, deeply golden edges and a distinctive salt-and-vinegar flavour. The red potatoes are first simmered in a mixture of white vinegar, salt, and water. After becoming tender, they are gently flattened, brushed with olive oil, and air-fried with whole garlic cloves and fresh rosemary.
Why Boil Potatoes in Vinegar?
Simmering the potatoes in vinegar allows the sharp flavour to penetrate beyond the surface. The potatoes absorb enough acidity to taste tangy without becoming unpleasantly sour. Adding water prevents the vinegar from becoming overpowering, while salt seasons the potatoes as they cook.
Vinegar also helps the potatoes retain their shape during boiling. This is useful because they must become tender enough to flatten without falling completely apart. Red potatoes are particularly suitable because their waxy texture and thin skins hold together well.

How to Smash Them Correctly
The potatoes must be completely tender before smashing. Test them with a fork or small knife after approximately fifteen minutes. Larger potatoes may require a few extra minutes. If they are still firm in the centre, they may break into pieces instead of flattening.
Drain them thoroughly and allow excess steam to escape briefly. Place them on a sturdy oven tray and press each one gently with a potato masher or the back of a large spoon. The skins should split and the potatoes should flatten, but they should remain in one piece.
Thinner potatoes develop more crisp surface area, while thicker ones retain a softer and fluffier centre. Aim for an even thickness so they cook at approximately the same speed. Brush olive oil across the tops and around the exposed edges, where it helps create the crispest texture.
Getting Crispy Air-Fryer Results
Preheat the air fryer before adding the potatoes. Arrange them in a single layer and leave some room between them. Good airflow is essential because trapped steam will soften the surfaces. Cook in batches when the basket cannot comfortably hold all the potatoes.
Turn them during cooking so both sides become evenly browned. Add the garlic after the first ten minutes to prevent it from burning. Rosemary needs even less time, so it is added during the final five minutes. This releases its aroma without making the leaves dry and bitter.
Handle cooked food and leftovers carefully, keep preparation surfaces clean, and refrigerate unused portions promptly. Further advice is available from the FDA safe food handling guidance.
Serving Ideas and Flavour Variations
These crispy rosemary potatoes are suitable as a side dish with grilled vegetables, burgers, roasted meat, chicken, or fish. They can also be served as a snack with garlic mayonnaise, mustard dip, vegan sour cream, or a fresh herb sauce.
Smoked paprika creates a warmer flavour, while chilli flakes provide heat. Rosemary can be replaced with thyme, oregano, or sage. Apple cider vinegar is a suitable alternative to white vinegar when a slightly milder and fruitier acidity is preferred.
For additional plant-based meal inspiration, explore the vegetable recipes section. The potatoes work particularly well on a barbecue table or as part of a relaxed family dinner.
Dietary Notes and Storage
The basic ingredients are naturally free from dairy, eggs, gluten, nuts, and animal products. Check the labels of any dips or sauces served alongside the potatoes if specific dietary restrictions apply.
Store leftovers in an airtight container in the refrigerator for up to three days. Reheat them in the air fryer at 190°C (375°F) for five to eight minutes. This restores much of the crisp texture that is lost during refrigeration. Microwaving is quicker, but it produces softer potatoes.
Freezing is not recommended because the centres can become grainy or watery after thawing. Served directly from the air fryer with an extra pinch of salt, vinegar smashed potatoes provide a satisfying combination of acidity, herbs, garlic, and crisp edges.
