There’s something magical about a bowl of creamy, cozy udon, especially when the weather turns chilly and all you want is a warm, comforting meal that doesn’t take forever to make. This One Pot Masago Udon is one of my all‑time favourite comfort dishes, and if you’ve been here a while, you’ll know I’ve been making versions of this for years.

I’ve written about it before (the recipe is slightly different) in an old post which you can still find here. But clearly, it shows that I’ve been eating this Masago udon for years because it’s just that good. This updated version is even easier, creamier, and more flavorful. It’s the perfect weeknight dinner or rainy‑day treat. It’s quick, it’s indulgent, and it hits every umami note perfectly.

Masago, a delightful fish roe, is the star ingredient here, adding a pop of color and briny goodness to our udon.

First, let’s talk about Masago

What is Masago? Masago is the roe (eggs) of the capelin fish, a small, cold-water species found in the North Atlantic and North Pacific oceans
Flavor Profile: Masago has a distinct and delicate briny flavour, often described as slightly salty and seafood-forward
Texture: It has tiny, bead-like grains that burst with a satisfying pop when you bite into them
Color Varieties: Masago comes in various colours, with the most common being orange, but you can also find black, green, and even red varieties
Common Uses: It’s a popular ingredient in Japanese cuisine, frequently used to garnish sushi, sashimi, and as a flavourful addition to various dishes like udon, salads, and sushi rolls

Got Leftovers?

This dish is best enjoyed immediately, but if you do have leftovers:

Store in the fridge for 2–3 days
Add a few drops of water before reheating to steam the noodles
Microwave in short intervals to avoid overcooking
The udon will soften slightly, but the flavour stays incredible.

Method

Remove the udon noodles into a large pot and set aside.
If using meat, sear the meat lightly on medium heat with a bit of oil if preferred, and then add in your udon noodles. Turn heat to low and add in your masago mayo mixture, soy sauce, and green onions.
If it gets too dry, add a few tablespoons of water to the pan.
Toss for 1-2 minutes until udon is evenly coated with the sauce.
