Turning 30 means you've survived the beginning of adulthood. You might even want a kitchen that matches your level of maturity.

To figure out what every adult kitchen needs (besides the basics, like silverware, cups, and plates), Business Insider consulted America's Test Kitchen, which is home to 50 food experts and the popular cooking show of the same name.

Bridget Lancaster and Julia Collin Davison, two culinary scientists at America's Test Kitchen and hosts of the TV show's 2017 season, told me the tools everyone needs in their kitchen by age 30.

"If I only knew then what I know now ... I would have bought more core kitchen equipment and fewer single-use gadgets," Lancaster says.

A slow cooker.

A slow cooker is an easy way to make gourmet-tasting meals that are full of flavor, Lancaster says. Just throw all the ingredients in the pot, and let them roast.

Lancaster recommends: The KitchenAid 6-Quart Slow Cooker With Solid Glass Lid ($68.99)

An 8-inch chef's knife.

A quality knife that's easy to hold and keeps a sharp blade will make kitchen work fast and easy, Lancaster says.

Lancaster recommends: The Victorinox Fibrox 8-inch chef's knife ($44.99) 

A manual or electric knife sharpener.

Whether you choose to invest in a manual or electric knife sharpener, you need one to keep your knives working properly, Lancaster says.
