This Miso Brown Butter Udon is a simple, deeply flavorful dinner that comes together in about 20 minutes. If you can find fresh udon noodles at the grocery store, grab them — they absorb sauce beautifully and give the dish a satisfyingly chewy texture. This version combines nutty browned butter with savory miso, soy, and a touch of heat for a quick weeknight meal or a versatile base for added protein and vegetables.
Miso Brown Butter Udon Recipe
Udon noodles are an ideal canvas for bold flavors. Their thick, springy texture catches sauce and brings texture to every bite. This recipe is intentionally flexible: keep it mild or dial up the spice, swap in different vegetables or proteins, and tailor it to your family’s tastes. It works beautifully for a quick weeknight supper, for using up odds and ends from the fridge, or as a base when you want something more interesting than takeout.
This version uses browned butter to introduce a toasty, nutty note that pairs perfectly with miso and a splash of sesame oil. Oyster mushrooms add meaty texture, bell pepper gives brightness, and baby spinach wilts down for color and nutrition. If you prefer, add shrimp, chicken, or tofu to make it heartier.

How To Make This Recipe
The following overview outlines the main steps. Full details and measurements are in the recipe card below.
- Sauté the vegetables — Brown the butter in a large, high-sided skillet over medium heat. Add sesame oil, then mushrooms, onions, garlic, and bell pepper. Cook until the mushrooms are lightly browned and release their moisture.
- Create the sauce — Stir miso, soy sauce, Japanese-style BBQ sauce (or teriyaki), and sambal into the pan. Let the mixture simmer briefly so flavors meld.
- Add the noodles — Add udon and a splash of water, cover the pan, and let the noodles steam for a minute or two. Use tongs to gently separate and coat the noodles in sauce.
- Finish with greens — Stir in baby spinach and cook just until wilted. Toss everything together so the noodles are fully sauced.
- Serve — Remove from heat, garnish with sesame seeds, and serve hot.
Recipe FAQ
Yes, but it’s best eaten right after cooking when the noodles are at their ideal texture. Leftovers are still tasty, though the noodles will soften slightly after refrigeration.
What’s the best way to store and reheat leftovers?
Transfer leftovers to an airtight container and refrigerate for up to 3–4 days. Reheat gently in the microwave or on the stovetop with a splash of water or extra sauce to loosen the noodles. A brief stir-fry in a hot skillet works well to revive texture.
Substitutions and additions
Swap oyster mushrooms for cremini, shiitake, or button mushrooms. Add cooked shrimp, grilled salmon, pan-seared chicken, or cubes of firm tofu for protein. If you don’t have the named Japanese BBQ sauce, use your favorite teriyaki or a comparable savory-sweet sauce. Sambal can be replaced with Sriracha, gochujang, or another hot sauce to taste.
