  1. MY FAVORITE. I have this dish at least twice a week! I’m not fully vegan, so I modify by using a lower fat mayo, and I also love adding kimchi or gochujang to it. Also, I always use mushroom powder and is so good. Thanks, Lisa, for this amazing recipe!

  2. My fave food when im rushing hahaha
    When i am out of ideas i accidentally tried this and my friend loved it very very much hahaha
    Thank you Lisa 😻💖

  3. I’ve made this 3 times for family meals and every time I get comments from meat eaters that they can’t believe it’s vegan and that delicious. I absolute adore this recipe

  4. One of my go to comfort meals! Like with a lot of Lisa’s recipes I was shocked I can make something so delicious in 5 min. Yummmm

  5. In love with this 5 minute udon recipes ❤️
    They are so yummy and easy to make.
    Especially in home office times, this is a good solution for quick but satisfying lunches!

  6. I’m a sucker for anything quick but tasty, and this is it!!! So good so creamy and only takes 5 min! Best best best for busy mommas 🤣

  7. I used my rice cooker to make this. added some cabbage while it steamed and some sesame oil at the end. DEFINITELY would make again (and I will after I try the sesame miso version.)

  8. Great recipe for a quick supper! I used a pan because we don’t have a microwave and it worked just fine. Love the miso and butter combination, really cosy. Thanks so much!

  9. this recipe and the shoyu udon one have both very quickly become my work from home lunch favorites. they’re so easy and don’t require any ingredients that you might not have around. plus you can pretty easily add or sub ingredients depending on what you have around.

    i have an executive functioning disorder which makes meal prep and cooking difficult but these udon recipes take nearly all the stress out of it which is why they grew on me so quickly. 🙂
