The best dip-friendly lunch boxes actually lock the sauce in.

The best lunch boxes for dipping have a dedicated, leak-proof sauce cup that’s built into the design — and the one I’d buy is the Bentgo Kids.

Bentgo Kids comes with a little round container that sits in the center compartment, so your kid can dip nuggets straight into ranch without the sauce touching everything else. The main lid seals tight over the whole tray, and that center cup stays put. In practice, it handles ketchup, hummus, and ranch without leaking in a lunchbox. I wouldn’t trust it with super-thin salad dressing, but for real dipping food it’s great.

If you want something more grown-up or stainless steel, the PlanetBox Rover plus the separate PlanetBox Leak-Proof Dipper is the better combo. The dipper has a screw-on lid that is genuinely watertight, and it snaps right into the box. It costs extra, but it’s the most reliable sauce container I’ve tested.

The Yumbox Tapas is also solid, but the Bentgo gets the nod for being cheaper and easier to find. Either way, don’t buy a box that just relies on the main seal to hold sauce in its compartments — that’s how you end up with a soggy sandwich.

Your nuggets deserve better than a leaky packet of ketchup.
