Miso Brown Butter Udon FAQ

Can this be made ahead of time?

It can, but it definitely tastes best right after cooking. That’s not to say the leftovers aren’t delicious, I just wouldn’t go out of my way to make this in advance if you can help it.

What’s the best way to store and reheat leftovers?

We threw them into a big freezer baggie and then reheated the leftover udon in the microwave. It was great, especially if you have a little extra sauce to drizzle over the top.

Are there any suggested substitutions or additions?

Yes! Some Teriyaki Shrimp would make a great addition here, as would a filet of Tingly Salt Salmon. If you don’t have Bachan’s Sauce, you can sub in your favorite teriyaki sauce. Sambal can also be replaced with your favorite spicy condiment, like Sriracha or Gochujang, if you have either of those handy.
