COMPARISON

Costco prepared food vs. Platera: which one suits your week

Costco sells cooked food in family formats, priced by the kilo and carried home in your car. Platera gathers kitchens in your city that deliver single portions. Both save you cooking, but they solve different weeks.

Costco prices checked in August 2026. They move often and vary by warehouse, so confirm before you go.

This comparison is different from the others on the site, and it is worth saying so up front: Costco is not a meal prep service. It is a warehouse where part of the business is already-cooked food, sold in large trays, meant for you to take home and divide up yourself.

People search for exactly that when they have stopped wanting to cook midweek, and it is a genuine option. This guide covers what the Costco deli actually carries, what it costs once everything is added up, and when it beats ordering from a kitchen in your own city.

Costco figures checked in August 2026 on their online store and their Rappi catalog. The Platera column varies by kitchen, because each one publishes its own terms.

What Costco prepared food is

The Costco deli carries cooked dishes that only need heating: rotisserie chicken, lasagne, pasta, breaded chicken breast, macaroni cheese, and a rotation that changes several times a year. In January 2026, for instance, five new dishes entered the deli.

The format is what shapes everything else. These are not single portions: they are large trays and whole pieces meant for a family, or for you to divide. The Kirkland rotisserie chicken weighs at least 1.36 kg and appears in Costco's Rappi storefront at $152.18. Read that figure carefully: it is the delivered price through a third party, and the same bird costs less at the counter.

Even so, the per-kilo arithmetic is hard to beat. A little over a kilo and a half of cooked chicken at that price is around $112 a kilo, and no portioned meal service in the country comes close.

Two things do not appear on the label. The first is membership: $600 a year for Gold and $1,200 for Executive, without which you do not get in. The second is that Costco does not deliver, so either you go or you pay somebody to go for you.

And a third, more practical one: you do not pick the menu. You buy what is there that day, in the size it comes in.

The arithmetic that is not on the label

Per kilo, Costco wins and it is not close. The more useful question is a different one: what does it cost to solve **a week of meals for one person**, which is the sum almost nobody does before comparing.

Start with membership. Six hundred pesos a year is fifty a month before you buy anything. If you shop there every couple of weeks that dissolves quickly and stops mattering. If you were going purely for the week's food, it is a fixed fee on top of every trip.

Then the format. A 1.36 kg rotisserie chicken is four or five meals, but they are four or five meals **of the same chicken**. Keeping a week from repeating means two or three different products, and there the ticket climbs and the freezer fills.

Then the trip. Going to Costco is not fifteen minutes: it is driving, parking, standing in line and coming back, and most people do it once or twice a month rather than weekly. That means buying days ahead and freezing, which is exactly the work you were trying to avoid.

And finally the work left over. The tray arrives whole. Dividing it into portions, labelling, freezing and thawing is yours. It is not much work, but it is not zero, and it repeats every week.

None of this makes Costco a bad option. It makes it an option for a specific case: somebody with a family, a freezer and a car who wants to lower the cost per kilo and does not mind repetition. If that is not you, the price per kilo is solving a problem you do not have.

What Platera is

Platera has no kitchen and no warehouse. It is where the kitchens in your city publish what they already sell, with their delivery zone, their days, their frequency and their prices, so you can compare them without messaging each one.

The difference from Costco is not price, it is the unit. Costco sells volume and you divide it. Platera sells meals: one portion, ready, delivered, and tomorrow's can come from a different kitchen.

There is also no membership and no service fee for the buyer. The commission comes from the seller, and the price inside Platera has to match what that kitchen charges over WhatsApp or in person.

The drawback in full: per kilo you will pay more than a warehouse, always. You are paying because somebody else portioned, packed and carried it. If cost per kilo is your priority and you have somewhere to store it, Costco is the right answer and there is no point pretending otherwise.

How to choose between buying by volume and buying by portion

This is not a question about price, it is one about format. These five questions usually settle it before price matters at all.

How many people are you cooking for?
One or two people and a family tray almost always end the same way: eating the same thing for four days, or throwing food out. From three or four upwards, the large format starts to make sense on its own.
How much freezer do you actually have?
Buying by volume is buying storage. If your freezer is the one on top of the fridge and it already has things in it, the per-kilo saving becomes theoretical.
How much does repetition bother you?
This is the one people most underestimate. Monday's lasagne feels very different by Thursday, and food you do not eat was not cheap, it was waste.
How often can you actually go?
If you can go weekly, the large format fits your week. If you go monthly, you are freezing out of necessity and planning three weeks ahead.
What is your Sunday worth?
Dividing, labelling and freezing takes a solid half hour each time. That is not much. But if the point was to stop spending time on food, it counts as time spent on food.

Which to choose

If there are four of you at home, you have a freezer and a car, and the goal is to lower the monthly food bill, Costco is the answer and this guide will not try to talk you out of it. On price per kilo there is no contest.

If you are one or two people, the arithmetic changes. The family format stops being a saving the moment food is left over, or the moment you eat the same thing on Thursday because it has to be finished.

And if what tires you is not the price but the logistics, the cooking, planning, driving and portioning, then the two are not really competing. Costco removes the cooking. A kitchen in your city removes the cooking, the planning, the trip and the portioning.

They also combine perfectly well, and plenty of people land there: the shop and anything freezable from the warehouse, and everyday meals handled by somebody who delivers nearby.

Frequently asked questions

What prepared food does Costco carry in Mexico?

The deli carries cooked dishes to reheat: rotisserie chicken, lasagne, pasta, breaded chicken breast and macaroni cheese, plus a rotation that changes several times a year. The selection varies by warehouse.

How much does Costco rotisserie chicken cost?

In Costco's Rappi storefront it appears at $152.18 for a piece of at least 1.36 kg, checked in August 2026. That price includes third-party delivery; the same bird costs less at the counter.

Do I need a membership to buy prepared food at Costco?

Yes. Gold membership costs $600 a year and Executive $1,200, and both include a second card for someone at your address. Without a membership you cannot enter the warehouse.

Does Costco deliver prepared food?

Not directly. Third-party platforms will collect and deliver your order, with their own delivery charge and a higher per-item price than the warehouse.

Is Costco cheaper than a prepared meal service?

Per kilo, almost always. Per meal actually solved for one person, not necessarily, once you add the membership, the trip and the food that goes to waste when the format is larger than you need.

What is the difference between Costco and Platera?

Costco sells volume and you divide it. Platera is a marketplace where kitchens in your city sell ready single portions, with their zone, days and prices published, and they deliver.

Does Platera charge a membership?

No. There is no membership and no service fee for the buyer. The commission comes from the seller, and the price inside Platera has to match what that kitchen charges on its own.
