Cook’s tips
- Use fresh udon noodles if available; they have the best chewy texture.
- Fry the shallots in a single layer and watch them closely—they go from golden to burnt quickly.
- Whisk the miso into the melted butter off the heat to prevent it from burning and turning bitter.
- If the sauce seems too thick, add a splash of the noodle cooking water to loosen it and emulsify.
- For extra flavor, toast the sesame seeds in a dry pan before garnishing.
Substitutions
- Use red miso or chickpea miso instead of white miso for a deeper, saltier flavor.
- Swap butter for vegan butter or olive oil to make the dish dairy-free.
- Substitute udon with soba noodles or thick ramen noodles if needed.
- Replace shallots with thinly sliced leeks or red onions for the crispy topping.
- Add a pinch of chili flakes or a drizzle of chili oil for a spicy kick.
Storage & reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in a skillet with a splash of water or broth to loosen the sauce, or microwave in short bursts, stirring between intervals.
Frequently asked questions
Can I make this dish ahead of time?
You can prepare the crispy shallots and the sauce in advance, but it's best to cook the noodles fresh and toss them together just before serving to maintain the best texture.
What if I don't have miso paste?
You can substitute with a mix of soy sauce and a little tahini or peanut butter for a similar umami-rich flavor, though the taste will differ slightly.
Can I add protein to this udon?
Absolutely! Grilled chicken, pan-seared tofu, or even a soft-boiled egg make great additions. Just cook your protein separately and toss it in with the noodles.
Is this dish spicy?
No, it's not spicy by default. The heat comes only from the optional chili flakes or chili oil you might add. Feel free to adjust to your preference.
