What Is Yakisoba?

Before diving into the Costco version, it helps to understand yakisoba itself. Yakisoba is a stir-fried noodle dish combining noodles, protein, vegetables, and a sweet-savory sauce. It originated in Japan and rose in popularity during the mid-20th century, becoming a staple at street stands and casual eateries.

The name breaks down simply: yaki means “grilled” or “fried over direct heat,” while soba in this context refers broadly to noodles rather than buckwheat. Yakisoba typically uses Chinese-style wheat noodles made from flour, alkaline salt (kansui), and water.

Costco’s version uses chicken, but yakisoba is versatile and works well with shrimp, beef, mushrooms, or tofu—choose the protein you prefer.

Yakisoba Noodles Costco Review

I’m often skeptical of pre-cooked meals because they can be overly salty or lack balance. After trying Costco’s Chicken Yakisoba, I was pleasantly surprised—this prepared meal hits a good balance of flavors and textures.

It makes a great weeknight dinner: fast to prepare and satisfying. My family enjoyed the tender noodles and the mix of vegetables that add both color and crunch.

The vegetable mix—bell peppers, red onions, broccoli, celery, and snap peas—adds texture and freshness. The sauce is flavorful without relying on heavy Worcestershire or oyster sauce, which helps keep it from becoming too salty while still providing depth.

Portion sizes are reasonable; a single container served my family of four. If you have larger appetites, you can stretch the meal with extra noodles or vegetables. At under $20 per container, it’s an affordable alternative compared with takeout.

Yakisoba Noodles Costco Cooking Instructions

Because the components are pre-cooked, reheating is simple. Cooking in stages yields the best texture:

  1. Heat 1/4 cup oil in a large skillet over medium-high heat.
  2. Add the vegetables and stir-fry for about two minutes to crisp-tender.
  3. Add the chicken and cook another two minutes until heated through.
  4. Stir in the sauce and noodles and cook one to two minutes, checking until noodles are warmed and softened to your liking.

Although the package suggests one minute for the noodles, they may need a bit longer to reach the desired texture—check after a minute and continue heating as needed.

For food safety, aim to reheat leftovers to an internal temperature of 165°F (74°C) to reduce the risk of foodborne illness.

Costco Yakisoba Stir Fry Price

Costco prices this prepared yakisoba at about $5.99 per pound. Containers typically weigh between 3.25 and 3.75 pounds. We paid roughly $19.53 for a little over three pounds—enough to feed our family of four.

Compared with restaurant versions, the Costco prepared meal offers strong value. If you prefer a convenient, affordable prepared dinner, this yakisoba is a solid choice.

What Is The Sauce On Costco Yakisoba Noodles?

The distinctive yakisoba flavor comes from a salty-sweet sauce. Costco’s sauce includes:

Soy sauce

Water

Sugar

Ketchup

Corn starch

Wine

Spices

Sesame seeds

Ginger

Garlic

Onion flakes

This blend omits Worcestershire and oyster sauces found in some recipes, which results in a milder, less salty profile while still delivering pleasant sweetness and umami.

Does Yakisoba Taste Like Ramen?

While yakisoba and ramen use similar wheat-based noodles, they are distinct dishes. Ramen is a broth-based soup, typically savory and salty. Yakisoba is a stir-fried noodle dish with a sweet-salty sauce and a different cooking method and texture.

Both noodle types are made from wheat flour and kansui (alkaline mineral water), which gives them a slightly yellow hue. The noodles are steamed and packaged, making them quick to reheat and ideal for prepared meals like Costco’s yakisoba.
