Udon Types

There are a variety of udon noodles that come in different thickness, shapes, and texture.

Udon noodles are mostly thick, but there are also thinner varieties. The texture can be firm or soft. And the shape can be flat and wide or square-shaped.

One of the most popular and well-loved udon noodles is Sanuki Udon (Japanese: 讃岐うどん). They’re thick, square-shaped with flat edges, and have a chewy elastic texture.

Manufacturers sell udon noodles in different forms and packaging. Such as fresh udon, dried udon, frozen udon, fully cooked udon, instant udon, and cup udon noodles. It’s important to note that different types need different cooking times.

*Note: For this udon soup recipe, make sure you’re using frozen udon noodles. You’ll find them in the supermarket’s freezer section.

Udon can be eaten any time of the day including breakfast or brunch. You can serve udon as a side dish or main dish in a meal.

Soba vs Udon vs Ramen

Ramen, Soba, and Udon are three of the most popular noodle types in Japanese cuisine.

Ramen (Japanese: ラーメン, 拉麺): Ramen is mostly made with wheat. They vary in thickness, but ramen is usually thinner than udon. Ramen’s color can range from white to yellow. The texture is al dente and chew to the bite.

Soba (Japanese: そば, 蕎麦): Soba is made mostly with buckwheat, hence the nutty flavors. The color is usually a distinctive brownish-gray. Soba is thin, softer, less elastic texture than ramen and udon.

Udon (Japanese: うどん): Udon is made with wheat. It’s white, with mild flavors. Depending on the variety, it’s usually thick, chewy, firm or soft, flat or square-shaped.

Tools for Udon Recipe

You only need basic cooking tools to make this udon noodle soup. If you like, you can use an Instant Pot instead of a regular pot on the stove. 

Noodle Strainer

For cooking any type of noodles, we love to use a Stainless Steel Mesh Noodle Strainer.

This strainer helps control the cooking time and easily strain the noodles. It’s a very convenient kitchen tool!

With this strainer, you can easily avoid overcooking the noodles. Also, you can shake out the excess liquid and prevent the water from diluting your broth’s flavors.

Step 1

Prepare Udon Recipe Ingredients

Soy Sauce

Kikkoman Organic Soy Sauce is an excellent choice for this udon recipe. This soy sauce may taste stronger than your usual soy sauce. Please remember to adjust it to your taste.

*Important Note: Different brands or bottles of soy sauce (same brand) can vary in their sodium levels, tartness, aroma, texture, and taste. As always, make sure to taste & adjust the amount accordingly.

Shrimp

For reference, we used 16/20 headless tiger prawns.

Simply peel and devein the shrimp.

*Pro Tip: Don’t throw away the shrimp shells! We’ll add them to the dashi to give the broth a little extra flavor boost.

Green Onion

Finely slice the green onions. We’ll use them to garnish the udon soup.

Dashi Stock

Homemade Dashi: It’s very easy to make homemade dashi with this dashi recipe. It definitely tastes better than instant dashi!

Substitute with Instant Dashi

If you don’t have time to make dashi from scratch, you can use instant dashi to make the dashi stock.

Mix 6g dashi powder (HonDashi) with 4 cups (1L) of water.

Step 2

Cook Shrimp in Dashi

Adding Shrimp Shells

1) If You’re Using Homemade Dashi: Add in the shrimp shells with the kombu.

2) If You’re Using Instant Dashi: Add in the shrimp shells with the shrimp.

*Note: 16/20 extra jumbo shrimp take roughly 4 to 5 minutes to cook in the dashi.

Set aside the shrimp once they’re fully cooked.

Step 3

Cook Soft Boiled Eggs

First, bring 7 cups (1750ml) of cold water to a full boil in a pot.

*Note: We’re using this pot of water to cook the eggs and frozen udon.

For Soft-Boiled Eggs: Boil eggs in the water for 5.5 to 6 minutes.

Drain & place eggs in ice-cold water to stop the residual heat from further cooking them.

Step 4

Season Dashi Broth

Add 2 to 2½ tbsp (30ml – 37.5ml) Japanese soy sauce to your dashi broth. Please don’t add them all at once!

*Instant Dashi Tip: If you’re using Instant dashi, you may need to add less soy sauce. Please taste and adjust accordingly.

*Pro Tip: Aim to have a slightly more salty dashi broth because the udon noodles will dilute the saltiness a bit.

Now, mix and bring your soy sauce dashi broth to a full boil.

*Note: If you’re using the Instant Pot to make your dashi broth, use the “Saute” button.

Step 5

Cook Frozen Udon

First, place the frozen udon noodles in your pot of boiling water.

*Pro Tip: Frozen udon cooks extremely quickly. It’ll take roughly 40 seconds to 1 minute to cook.

*Pro Tip: It’s extra helpful to use a Stainless Steel Mesh Noodle Strainer to cook udon! With a noodle strainer, you can easily scoop up the frozen udon, then give it a few shakes. This helps prevent soggy noodles and lets you drain them well.

Once cooked, remove udon from the water immediately.

Then, drain well and place the udon in a serving bowl.

Step 6

Now, place cooked shrimp and soft-boiled eggs on top of the udon noodles.
