What Are The Best Potatoes For Making Au Gratin

There are a few different types of potatoes that work well for gratins, depending on your preferences. Yukon Golds are a good all-purpose option, while Russets tend to be more fluffy and light.

For a richer colorful dish, try using a purple potato they are starchy and will help your gratin to hold together. Agria potatoes are also an excellent choice for their tasty yellow flesh. Whichever type you use, make sure to slice the potatoes thinly on a mandoline so they cook evenly.

What makes a gratin a gratin?

A gratin is one of the classic French dishes that typically consists of potatoes, cream, cheese, and sometimes butter. The dish is named for the way it is cooked, in a shallow dish with a browned and bubbly top. Potato gratin can be pressed until cold, portioned, and roasted in an oven.

Gratins can be made with different kinds of potatoes, including sweet potatoes, yams, and even pumpkin. In addition to the traditional potato gratin, there are also many other variations out there, including spinach gratins and broccoli gratins.

No matter what ingredients you use, the key to making a perfect gratin is all in the cooking method. Be sure to cook your gratin slowly and evenly so that the cheese or butter melts into a bubbly golden brown topping that will have everyone coming back for seconds.

Cooking Asparagus

I absolutely love asparagus it has such a short season in New Zealand. The asparagus season in New Zealand is from September to December, with a buildup in mid-October and dwindling off just before Christmas.

Asparagus is a perennial plant with an underground stem that produces an edible shoot, which is regarded as a delicacy. There are three varieties of asparagus. White which is harvested as soon as it appears above the ground, and purple asparagus which is allowed to grow several centimeters high.

Lastly, green asparagus which is the most common variety in New Zealand is harvested when the stalks are about 15 cm (6 inches) above the ground. Green asparagus has a full-flavored delicious taste, when it gets late in the season the green asparagus tends to start to seed and the edible shoots and stalks are not as tender.

I have always peeled asparagus stalks, it’s a chef thing. This gets rid of the stringy outer layer and is also presentable with the fresh green-looking stalk.


  • I blanch asparagus in a deep pot of boiling salted water for 30 – 40 seconds and refresh them in iced water. The process of blanching asparagus is the equivalent of completely cooking the vegetable. It also helps keep the vegetables an appetizingly healthy dark green color. From there they can be lightly grilled, sautéed, quickly reheated in boiling water or marinated, and served cold in a salad or an addition to a dish.

Larder Stables And Must Have Kitchen Tools

  • I’ll make it easy for you. stock your kitchen with these basic ingredients – Butter, milk, Himalayan pink or quality sea salt, whole peppercorns, sugar, vinegar, virgin olive oil, and plain flour.

Essential Kitchen Tools – Must Haves

You can’t be at a professional level in the kitchen unless you own a variety of high-end tools. Genius kitchen gadgets are an essential part of any home cook’s or aspiring chef’s arsenal. From some of the best chef knives, and kitchen cookware, to wooden cutting boards. These will set you apart from others and get you ready with what you need to start making meals like a chef.

My Professional Recommendations

Seasoning Food

Maldon Sea Salt Flakes
  • As a chef the most underrated ingredient in the kitchen is salt. When my recipes call for salt and pepper I use a variety of different salts and freshly ground black pepper.

Many chefs, including myself, prefer sea salt like Maldon salt flakes or Himalayan pink salt. Both can be used for cooking and finishing. They have a refined flavor that brings out the natural taste of food.

  • 2 tbsp Black truffle patѐ - optional

  • 50 grams Unsalted butter
  • ½ tsp Himalayan pink salt and freshly ground black pepper


  • 16 each Asparagus spears - cleaned and peeled
  • 4 each Vine-ripened tomatoes
  • 1 drizzle Smoke infused balsamic vinegar
  • 1 drizzle Olive oil - extra virgin

  • 10-15 each Capers
  • 3-4 tbsp Olive oil - extra virgin

Using A Mandolin

  • When using a mandolin make sure it has a guard to protect your fingers and knuckles from the sharp cutting blade
    If you don’t have a mandolin you can use a knife. However, I would recommend using a mandolin for consistency and it’s easier.  
    Here are a couple of options from Amazon – Plastic Option or Stainless Steel.  I much prefer stainless steel, easier to clean and won’t crack.

    Slice the butter and lay it on top, cover the tin with aluminum foil, and place it into the oven for 35 – 45 minutes.
    When cooked carefully remove the foil, poke a knife into the center of the gratin it should be quite tender.
    Place into the fridge to completely cool, should take only 2 hours to cool.  This can be made the day before.

Fresh Herb Pesto

  • Place all the pesto ingredients into a cylinder-shaped container the same ones you get when you buy a stick blender. Or you can use a bullet blender.
    Blend ingredients until a thick paste has formed, it should only take 1 minute or less.
    If you blend the pesto for longer than 1 minute the herbs will start to heat up and your pesto will come out a light green, almost grey color which doesn’t look very appetizing.

  • Place into a container and put it to one side until required.
