5. A Dutch Oven
This is definitely one of those things you probably wouldn't splurge on for yourself, but it's an item that belongs in your arsenal if you like to cook. You can basically make anything in it, and throw it in the dishwasher to boot. Trust us, this will be one of those things you use for your entire marriage (which will hopefully be very long!). This one from All-Clad has five bonded metal layers and is safe for any stovetop cooking and is also oven-safe.
