If you’re looking for a quick and delicious meal, try this Udon Noodle Soup featuring Costco’s Shrimp Tempura. It’s a 15-minute recipe with simple ready-to-go ingredients and the rich flavors of traditional Japanese soup. The soup contains chewy udon noodles and a savory broth, all topped with crispy shrimp tempura that bakes up in just minutes.

Costco Shrimp Tempura

Traditional tempura can be tricky and time-consuming to make, requiring precise batter mixing and deep frying. Costco’s frozen shrimp tempura offers a hassle-free alternative—just bake or air fry according to the package directions, and you get perfect tempura every time. I recommend two shrimp per serving, but feel free to adjust based on your preference.

What is Udon Soup?

Udon soup features thick, chewy noodles served in a dashi-based broth. It’s loved for its satisfying texture and umami flavor. Udon can be paired with various proteins and toppings like fish cakes, egg, green onions, and fried tofu, making it a versatile and filling dish.

Ingredients:

Frozen Udon Noodles: You can use frozen for quick cooking or opt for dried or fresh if you prefer. I recommend using frozen udon noodles if you can find it. Frozen udon noodles have a chewy, satisfying texture and cook up in just 1-2 minutes.
Costco Shrimp Tempura: Pre-cooked according to the package. They bake up golden and crispy in just minutes in the air fryer or oven.
Soft Boiled Eggs: Peeled and halved, adding a creamy texture to the soup.
Green Onion: Use the green parts only, thinly sliced, to add a fresh, herby flavor.
Roasted Nori: Kirkland roasted nori is perfect for adding a crispy, sea-flavored topping. It comes in pre-cut sheets, making it easy to use and store the leftovers in an airtight container to keep them fresh.
Togarashi Seasoning: Optional, but adds a spicy, aromatic kick with ingredients like red chili peppers, sichuan peppercorns, and dried orange peel.

For the Broth:

Water: Starts the base of your broth.
Anchovy Broth Cube: These cubes are a quick way to add depth to your soup. They are found at Asian grocery stores. Use half a cube for this recipe, breaking it with a knife. Store the other half in a zip-lock bag for future use.
Hondashi Powder: Provides a quick, flavorful dashi stock alternative made from bonito flakes, perfect when you’re short on time.
Soy Sauce: For that essential umami flavor.
Mirin: Adds a touch of tang and sweetness to balance the broth’s saltiness.

The ingredients ready to be assembled: soft boiled eggs, udon noodles, broth, seaweed

Prepare the Eggs: Soft boil the eggs by cooking them in boiling water for 7 minutes, then cool them in an ice bath. Peel once cooled. You can do this step in advance.

Cook the Noodles: Bring a pot of water to a boil and cook the udon noodles as per the package instructions. Drain and set aside.

Cook the Shrimp Tempura: Bake or air fry the shrimp tempura as directed on the package. This ensures they remain crispy.

Instructions:

Make the Broth: In another pot, combine water with half an anchovy broth cube and Hondashi powder. Bring to a simmer until everything dissolves. Season with soy sauce and mirin for that perfect umami taste.

Assemble the Soup: Place noodles in a bowl, pour the hot broth over them, and arrange the soft-boiled eggs, green onions, and nori on top. Sprinkle with Togarashi seasoning if you want a hint of spice.

Add the Shrimp Tempura: Place the cooked shrimp tempura on top right before serving to keep the batter crisp. You can also serve the tempura in a separate plate if preferred.

Serving Suggestions:

This Udon Noodle Soup with Shrimp Tempura is best enjoyed immediately while it’s hot and the tempura is crispy. It’s a fulfilling meal on its own but can also be paired with a light salad for added freshness.

This easy recipe is perfect for anyone wanting to whip up a quick yet satisfying meal using convenient, quality ingredients from Costco. Enjoy the combination of chewy noodles, rich broth, and crispy shrimp for an amazing udon soup experience at home!
