Method

  1. Step 1

    Begin by washing and slicing the hasselback potatoes (6 potatoes). Slice the potatoes but do not cut all the way through. A good tip is to lay two wooden spoons flat and place the potato between the handles. Cut through until your knife reached the handles of the wooden spoons as shown in the video.

  2. Step 2

    Place the potatoes (6 potatoes) into an oven dish with reasonably high sides. Make sure the potatoes fill the dish. Pour over the melted butter (30 g) and brush using a pastry brush until the potatoes are evenly coated.

  3. Step 3

    Sprinkle with salt and pepper and place into a preheated oven at 200°C-390°F for 45 minutes.

  4. Step 4

    Next, pour the cream into a saucepan followed by 3 cloves of lightly crushed garlic (6 garlic). Add a pinch of salt and black pepper. Then, add a couple of thyme (4 sprigs) sprigs and bring them to a simmer. Once simmering take off the heat and set to one side until the potatoes (6 potatoes) are cooked.

  5. Step 5

    Thinly slice 3 more cloves of garlic (6 garlic) and stud them into the cooked hasselback potatoes (6 potatoes). Sprinkle with some chopped thyme (4 sprigs).

  6. Step 6

    Remove the garlic (6 garlic) cloves and thyme (4 sprigs) sprigs from the cream. Pour the infused cream over the potatoes (6 potatoes) and grate over the mature cheddar cheese (60 g).

  7. Step 7

    Place back in the oven for around 30 minutes or until crisp and golden on top.

Questions people ask

How long does hasselback dauphinoise take?

About 1 hour 25 min from start to finish, of which 10 min is prep and 1 hour 15 min is cooking. That figure is worked out from the method rather than timed with a stopwatch, so give yourself a little more the first time.

How much does this make?

The original recipe did not state a yield, so nothing has been invented for it. The scale control on the recipe card multiplies the quantities instead, which is the honest version of the same thing.

Can I see the ingredients in ounces and pints?

Yes. The metric and imperial switch on the recipe card converts every quantity, rounded to amounts you can actually weigh or measure rather than to four decimal places. Your choice is remembered for every recipe on the site.

Is it vegetarian?

Yes, as written. If you are cooking for a strict vegetarian, the one to check is the cheese: several hard cheeses are made with animal rennet.
