Ninja say that the 'Air Fry' function means up to 75% less fat than traditional frying methods (when tested against deep fried, hand-cut French fries).

The heating element near the top of the fryer emits heat into the air in the cooking chamber (radiation), while a fan circulates the heated air rapidly around it (convection). This combination creates a very intense heat transfer, resulting in a cooking method that's closer to frying than baking.

It's much healthier than using a deep-fryer, but with little or no oil you can create crispy browned food faster than oven baking.

The 'Bake' function is similar to baking in a fan oven (convection) but often the food can appear cooked on the outside but be raw in the middle. I suggest generally decreasing the temperature by 20 degrees compared to the standard oven temperature. This cooking process cooks from the outside in. You also need to consider the material of your cooking dish when you decide on the bake time. A metal conducts heat whilst a silicone liner is heat resistant.

The 'Pressure Cook' function cooks food with the use of high pressured steam using a minimum of 250ml of liquid. It allows food to be cooked much faster by trapping the steam and increasing the boiling point so that tough meat becomes tender very quickly.

Ninja say it’s up to 70% faster than traditional cooking methods.

The 'Sear/Sauté' function is the same as cooking in a saucepan on the hob, but you have a very big pot! Great for sautéing vegetables and you can control the temperature. I even used this function to melt ingredients to make Kinder Rice Crispy Cakes !

The 'Slow Cook' function is a convenient way of creating meals with a cook time up to 12 hours. This ensures your favourite risotto, casserole or tender pulled pork is ready when you get home and will automatically switch to 'Keep Warm' once cooked.

The 'Steam' function can be used to re-heat food (in a pot covered in foil) with water in the bottom of the ninja pot. It retains the moisture in the food so is an ideal use for this function. When using 'Steam' the Ninja allows steam to escape unlike pressure cooking, making it ideal for more delicate food like fish, vegetables and even rice.

The 'Grill' function is a powerful cooking option using high intense heat, perfect for crisping up fat on lamb chops or melting and bubbling cheese on a pasta dish. It’s the hottest option on the Ninja, so it works well for pre-heating when needed.

Making yogurt is incredibly simple using the Ninja Foodi 'Yogurt' function with only 2 ingredients needed.
It’s a lengthy process due to the fermentation but you can walk away and let the Ninja do the work for you.
Making your own homemade Yogurt from scratch is ultra satisfying and also very cost effective.

Use the 'Dehydrate' function to create vegetable crisps, dried fruit snacks, homemade jerky and dried herbs. You can even cook a joint of beef for a pink soft interior with a browned outside crust.

The 'Steam Air Fry' function creates steam-infused air which cooks your food without drying it out. Enjoy healthier fried food that’s moist and juicy on the inside, crispy on the outside. It’s also perfect for quickly cooking a risotto or a one-pot lasagne with a bubbling cheese topping.

The 'Steam Bake' function creates the most fluffy, moist and light cakes. The steam circulates around your food and can offer protection like a water bath. Delicate custard recipes bake well using this method.

The 'Prove' function is used to prepare your dough for being cooked under steam, by warming it at a low temperature to increase its size.

The 'Steam Meals' function makes family meals in under 30 minutes, layering mains and sides with the 2-tier rack to create complete, delicious one-pot meals. Try a classic Sausage & Mash with Veg, Stuffed Chicken with Pasta or Salmon, Rice with tender vegetables.

The 'Steam Bread' function gives several benefits including good crust coloration and shine, and a thinner crispier crust. The steam keeps the crust moist preventing it from solidifying too soon and thus helping the bread expand more.

The 'Steam Roast' function is great for cooking large joints of meat and whole chickens. It keeps the flesh tender but produces a crisp exterior.

The leave-in cooking 'Probe' is a digital meat thermometer which allows you to cook to temperature rather than time. It monitors the temperature of your food as it cooks so you can enjoy food cooked precisely to your taste without the guesswork. It is neatly stored away when not in use on the side of the foodi.

The 'Keep Warm' function automatically switches on after pressure cooking, steaming and slow-cooking, retaining a safe food temperature for up to 12 hours. You can switch this on manually after using other functions by selecting 'slow cook' then using the 'buffet' setting.
