Why we love quick roast potatoes

As much as I love a crunchy, twice or triple cooked, roast potato, they take quite a bit of time to cook. They usually call for a lot of butter, oil or fat too. On the other hand, these quick roast potatoes are just the thing when you are short on time. Or if you are looking for a healthier version.

To get these potatoes on the table quickly, we take a few short cuts. Firstly, we leave the skins on the potatoes so you don’t need to peel them. Secondly, we pre-cook the potatoes in the microwave to get a head start on the cooking time.

As an added bonus you’ll hardly have any dishes to clean up. This recipe only uses a microwave-safe container and roasting dish. Or you can use a baking tray lined with non-stick paper instead of a roasting dish.

Ingredients

You’ll only need a few ingredients to make these allergy-friendly quick roast potatoes:

  • 500g (1.1 lb) of small cocktail potatoes, washed
  • 1 Tablespoon fresh rosemary (chopped)
  • 1 Tablespoon of olive oil
  • pinch of sea salt

Method

Preheat your oven to 200C (400F).

Cook cocktail potatoes in a covered microwave safe dish on high for 6 minutes. (Our local supermarket even sells cocktail potatoes in microwave safe packaging – in which case you can pop the bag straight into the microwave!)

Remove the potatoes from the microwave and tip onto a chopping board. Cut each potato in half with a sharp knife. Take care as the potatoes will be very hot. You may need to cut some larger potatoes into 4 pieces to ensure that all the potato pieces are roughly the same size.

Place the potatoes into the baking dish or spread over a baking tray lined with non-stick paper. Add 1 Tablespoon of olive oil and toss to coat. Sprinkle chopped rosemary over the potatoes and season with sea salt.

Place the roasting dish/baking tray in the oven and cook for 25-30 minutes or until the potatoes are golden brown.

Serve with your choice of main dish. Or for a shared side dish, tip the potatoes into a serving bowl and garnish with a sprig of fresh rosemary.

Serves 4. To serve 8, simply double the quantity and use a larger baking dish/tray.
