Best vegan crunchy roast potatoes. A failproof method for guaranteed crunchy yet fluffy roast potatoes! Methods for Air Fryer or Oven Bake!
I am a potato girl. I have Manx heritage so I am bound to. One of the traditional dishes from the Isle of Man is boiled potatoes and herring. Let's leave the herring to the seagulls, and give me all the potatoes.
I can eat potato in pretty much any variant that is edible, hell, I even used to eat them raw as a kid. I can still remember that crunchy earthiness that they have, freshly peeled, but I don't crave it these days.
I grew up in a little cottage on a farm, and the farmer, taking pity on a young single mother and her little daughter, would always give us a sack of potatoes at the beginning of winter. They would last us throughout the season.
Of course, as you can imagine, we had to have them in many different ways, chipped, mashed, sauteed, baked and, always on Sundays, roasted.
As I wrote on my post about vegan mashed potatoes, mash is my absolute go-to potato dish. I could eat it every day.
With this in mind, it might not seem so strange that traditional roasted potatoes have never been my favourite. I think potatoes are best mashed or hashed! Roasted potatoes are usually cooked in lard or goose fat and, in my experience, a good cooked potato should be just as tasty or better the next day. Congealed grease does not make for tasty leftovers.
However, the traditional "roastie" is a staple on the English table and rather than depriving anyone of their cultural heritage I contrived this recipe to produce a crispy and delicious roasted potato that we can all enjoy together.
- Potatoes. Use a floury white potato. It will give you the fluffed up texture that all the best roasties have.
- Garlic cloves. Throw in with the roasties and they'll gift you a sweet, fragrant flavour.
- Thyme. My favourite winter herb. You can also use Rosemary.
- Polenta. I have also used Semolina, but this is not gluten-free. The polenta adds a delicious crunch and flavour to the roasties.

- Peel your potatoes. Cut them into evenly sized (but not necessarily shaped) pieces.
- Preheat your oven to 200c or your air fryer to it's recommended setting.
- In a large saucepan boil your potatoes in salted water for about 5 minutes. Drain.
- Add oil to a roasting pan and bring up to temperature in the pre-heated oven.
- In a large mixing bowl, add the polenta, thyme, garlic and some seasoning. Not too much salt as you already salted the water.
- Toss the drained potatoes in the polenta mixture and carefully but quickly tip into the roasting pan with the hot oil in it.
- Roast for up to an hour, depending on the size of your roasties, but until golden and crunchy, turning halfway through cooking. I recommend checking and turning after 20 minutes.
- Remove from oven and serve!
You can although they are definitely at their best straight from the oven. I find that once reheated they go quite hard and bit dry.
No, I don't recommend it. If you want to freeze roasties, I suggest just buying a bag of Aunt Bessie's roasties (actually not that bad). Potatoes are not really suitable for home freezing, in my experience.
