The thieves smashed their way into the £7m, five-bedroom house in Primrose Hill after gaining access through the garage.
Jamie, his wife Jools and their four children were not at home at the time and are believed to have been staying at their Essex mansion when the break in took place.

It is thought the thieves, who made off with personal items including jewelry, may have known the family were away from the house at the time.
The alarm was raised when a neighbour spotted that the front door was open.
Another neighbour, who asked not to be named, told the Telegraph: “The police regularly advise us to review our security arrangements at this time of year as burglars are known to scout the area looking for empty homes.
"Jamie's home has got CCTV, but it seems it didn't help in this instance as the burglars got in through the garage."

Police are now investigating CCTV footage in a bid to find those responsible.
A Metropolitan Police spokesman said there had been no arrests after the incident earlier this month.
He said: “Police were called to an address in NW1 on Friday, 2 October shortly after 9pm after a member of the public reported that a door to the property was open.
"Officers attended and went inside the property and found that the premises had been burgled.
"Items were removed from the address."
Jamie and his family are believed to be moving from the property after snapping up a new £10million, eight-bed Grade II-listed home in nearby Hampstead in July.
Jamie Oliver's Grocery Shopping Tips
Keep Cupboards Stocked(01 of10)
Open Image Modal
Keep an eye out for store specials and load up on non-perishable stuff that sits in your cupboard waiting for you to come home and cook. It's good to remember that there's nothing substandard about canned tomatoes, canned fish or frozen fruits and vegetables. Unless you're picking them from your garden, you'll have to go a long way to get a tastier and more nutritional pea than a frozen one.
Shop With A List(02 of10)
Open Image Modal
One of my favourite tricks in the 20 Minute Meals Apps are the shopping lists. Make sure you take an inventory of what you have in your cupboard, take a look at what's on special and what's seasonal in your local market, create your menus and list and then head off to the store.
Check Those Labels(03 of10)
Open Image Modal
Avoid buying anything with ingredients on the label that you can't read or pronounce. Preservatives and chemicals aren't food.
Invest In The Best You Can(04 of10)

If you can afford to buy high quality organic chicken and beef that has been raised humanely, then do so. If you can't, look for less expensive cuts and choose recipes that braise and stew. You can do a lot with cheaper cuts and then be able to afford higher welfare animals.
Just Say No(05 of10)

Don't buy junk food and fizzy drinks. No need to reinforce bad habits.
Buy Close To Home(06 of10)

Try to buy fruits and vegetables in season that haven't travelled too far. They're usually cheaper and tastier. Root vegetables and dark greens are great in the winter time, and if you don't fancy, don't forget frozen.
Get Experimental(07 of10)

Try new things once in while. Substitute a sweet potato or a fingerling for a white potato, add a little heat with a chilli, try a shallot instead of an onion. You'll be surprised at how much more you enjoy shopping and cooking when you are exploring new things.
Make Friends With Salad(08 of10)

Salads should be creative and eaten every day if possible. Pick and mix different elements like soft and crunchy lettuce, herbs, veggies, cheese and various toppings. Once you've done that, simply mix them together, season, and dress the salad. See number 9.
Make Your Own Dressing(09 of10)

Never buy pre-made salad dressings. By dressing a salad, you can make it delicious, meaning you want to eat it, rather than feel you have to. The other good news is that your body can absorb far more nutrients from salads because of the presence of oil and acid in the dressing. I like to make dressings in empty, cleaned-out jam jars because it's so easy to see what's going on -- you can shake them up easily and any leftovers can be kept in jars in the fridge. Dressings are based on a ratio: three parts oil to one part acid. So experiment with different oils, extra virgin olive oil, hazelnut or grapeseed oil and different acids, lemon, vinegars, perhaps a little mustard for flavour, and season with salt and pepper. If the seasoning is there but you're finding it a little too acidic, you've cracked it, because once the dressing is on the salad leaves, it will be perfect.
Rely On Those Who Know(10 of10)

Get to know your butcher, baker and fishmonger. They will help you pick the best stuff at the best price. Sometimes it's worth going to three shops and a farmer's market because you have relationships with people who care about the food they are selling you.
