Product Review: Costco Yakisoba

Vegetable Yakisoba by Costco

Do you know what makes Costco so popular? It adds taste to convenience. It couldn’t be more true that frozen foods are a blessing from above and Costco Yakisoba is what we are thankful for today.

You could say all day that frozen food doesn’t taste as good and we should prepare our own meals all the time. But we’ll talk when you’re in a hurry, have surprise guests at your place, or just really crave a good meal at midnight.

Frozen foods are the real deal, and Costco makes sure that you don’t have to compromise on the taste. Such is the case with our today’s feature, the Costco Yakisoba Japanese stir-fried noodles.

Before starting, please note that this is an independent review, where only subjective experience and opinions are shared. Hipstafood is not associated with Costco.

Let’s get into it!

First Impression of Costco Yakisoba

As the packaging says, the Costco Yakisoba contains crisp vegetables, Japanese stir-fried noodles, and a savory sauce. Inside the box, you’ll find considerably fewer vegetables than what’s shown on the packaging.

The vegetable list as per the box contains water chestnuts, broccoli, edamame, Chinese pea pods, and mushrooms. But, one or two veggies on the list are sometimes missing inside the box.

The thick noodles take up the most space. I say thick compared to vermicelli or chow mein, so keep that in mind – they aren’t too thick either.


Here’s what interests you the most, and according to my skillful tastebuds, the Costco Yakisoba is worth it. The noodles and veggies have just the right amount of saltiness – the sodium. The seasoning is commendably good, in my opinion. I say this as someone who is more times than often adding his own mix to whatever frozen bought from Costco.

The noodles, I have to say, though a tiny bit thick for my preference, have just the right amount of texture and consistency – especially for a reheated food. Overall, you’ll sense some sesame and garlic in the Yakisoba – tastes really good, or at least good enough.


A bowl full of noodles and different kinds of vegetables sounds healthy, doesn’t it? The Costco yakisoba noodles, in one pack, offer you 11 grams of protein, 69 grams of carbs, 10 grams of fat, and zero cholesterol, all while being a decent source of iron.

The only thing you will frown at is the amount of sodium. To be honest, you don’t even need to look at the nutrition chart to know it has loads of sodium. So, despite it not being too much for the tongue, if sodium is your red flag, either avoid the Costco yakisoba noodles or keep your intake in check.


This is the most obvious part of a frozen food review. You’ll pretty much see this heading on every food blog. And rightly so, convenience is, after all, the primary reason why we get frozen food – good taste is just a plus point.

Let’s see how convenient the Costco Yakisoba really is. There are two ways of preparation: microwave and stove – I really prefer the first method. Just take the packet out, tear one corner, and set the timer for three minutes at high. That’s it, serve and eat.

It’s one of those foods that’ll satisfy your midnight food craving just enough that you won’t regret ordering a pizza—speaking from personal experience here.


The Costco Yakisoba noodles by Ajinomoto cost $16.16. A single box contains 6 packs of 255 grams. One pack is enough to make you feel full – or almost full. So, with that in mind, it’s not that expensive, especially with the convenience factor.

Cooking with Color Rating of Costco Yakisoba

I think that apart from the high sodium level in nutrition, the Costco Yakisoba noodles are good enough in everything else. But even the sodium thing is subjective, so it’s not a strong con here.

Overall, with good taste, decent nutrition, reasonable price, and great convenience, the yakisoba noodles Costco gets the Cooking with Color rating of 8/10.
