You Waste More Food on Vacation Than at Home. Here's the Easy Fix.

You know the moment. It is the last morning of the trip, the car is half-packed, and you are standing in the rental kitchen holding a nearly full bottle of olive oil, the ketchup you bought for exactly one burger night, and the leftovers from the dinner out last night. Into the trash it all goes.

Here is the part that surprised us. A peer-reviewed study from Ohio State found that travelers waste more food in a vacation rental than they do at home. The average travel party throws out about $12 of uneaten food per night, which is 32 percent more per day than the government's estimate for a family of four at home, even though travel groups are usually smaller. Nearly half of travelers, 47 percent, admit they waste more food on a rental trip than in their own kitchen. (Roe et al., Waste Management, 2025)

Why it happens

Here is the trap. You arrive excited to cook a few meals, and the store only sells you full sizes. A whole bottle of this. A family jar of that. A jar of spices when you just needed a pinch. For a stay that lasts three or four days, you are buying like you live there. The leftovers cannot fly home, so they go in the bin. The study even found that the most-wasted groceries are staples and produce, the exact things we tend to over-buy. And about a fifth of restaurant leftovers never get finished either.

Traveling with the family? It adds up faster.

If you are packing for kids, this one will not shock you. The researchers found that travel parties with children wasted significantly more food, and the youngest travelers wasted the most of all. No judgment here. More people, more snack runs, and more kid-friendly flavor demands simply mean more odds and ends left behind at checkout.

The first time this really hit us, we were on a Caribbean island. We were still recovering from the sticker shock at the one grocery store (a giant olive oil, a full-size mayo, a few spices for pasta night) when we found ourselves tossing all of it before the airport run. My first thought: what a waste. My second: where does all this trash even go on an island?

The simple shift: bring the flavors, not the bottles

The food you actually miss on a trip is rarely the groceries. It's the flavors. The good salt and hot sauce that make the eggs worth eating. Honey, cinnamon, sweeteners for morning coffee or tea. A few spices and olive oil for the dinner you cook yourselves. Those travel in an ounce, not a pound.

That is exactly why we built Travel Sauce the way we did: right-sized portions of the things that make a rental kitchen feel like yours, without the half-used bottles you leave behind.

And then there is the plastic

We always feel a little pang buying a giant plastic bottle for a long weekend, then hauling it, still mostly full, to the bin on the way out. It feels even stranger on a small island, where you find yourself wondering where all of that actually goes. The nice part about packing small is simple. When you bring only what you need, there is no giant bottle to toss in the first place.

A smarter way to pack for the kitchen

• Pack flavor, not inventory. A few small must-haves beat a cart of full sizes.
• Plan for the trip length, not the pantry at home.
• Whatever you bring, bring amounts you can actually finish.

Vacations are for the good parts, not the last-morning fridge cleanout. A little planning means more money for the fun, less in the trash, and meals that still taste like something.
