Ingredients You’ll Need
Udon and base
- 2 packs frozen udon noodles (about 8–9 ounces each)
- Frozen udon gives the best chewy texture; I like brands like Shirakiku or any labeled “Sanuki style.”
- If you only find shelf-stable udon, cook it slightly under package time so it stays bouncy.
- 1 tablespoon neutral oil (canola, avocado, or grapeseed)
- 1 tablespoon unsalted butter (or vegan butter for dairy-free)
Mushrooms and veggies
- 10–12 ounces mixed mushrooms, sliced
- Use a mix like cremini, shiitake, oyster, or maitake for deeper flavor.
- If you only have button mushrooms, slice them a bit thicker so they keep some bite.
- 1 small yellow onion, thinly sliced
- 2 cloves garlic, minced
- 1 teaspoon grated fresh ginger (optional but adds warmth)
- 1 small carrot, cut into thin matchsticks or half-moons (optional crunch and color)
- 2 green onions, thinly sliced (white and green parts separated)
Sauce and seasoning
- 2 tablespoons soy sauce (use low-sodium if you watch salt)
- 1 tablespoon oyster sauce or vegetarian mushroom stir-fry sauce
- 1 tablespoon mirin or 1 teaspoon sugar plus 2 teaspoons water
- 1 teaspoon toasted sesame oil
- 1 teaspoon miso paste (white or yellow; adds depth and umami)
- 1 to 1½ cups vegetable broth or chicken broth
- Boxed broth works fine; I like low-sodium so I control the salt.
- ½ to ¾ cup heavy cream or half-and-half
- For a lighter version, use half milk and half broth and simmer a bit longer to thicken.
- ½ teaspoon black pepper
- ¼ teaspoon crushed red pepper flakes (optional heat)
- Salt to taste
Toppings and finishing touches
- Extra sliced green onions
- Toasted sesame seeds
- Chili crisp or chili oil (optional but amazing)
- Nori strips or furikake (optional, for extra umami)
- A squeeze of lime or lemon (optional brightness)
Equipment
- Large skillet, sauté pan, or wide Dutch oven
- Medium pot to cook or warm udon (if not using frozen that you add straight in)
- Tongs or chopsticks for tossing noodles
- Ladle or measuring cup for broth
Tips & Tricks
- Use high heat to brown mushrooms so they caramelize instead of steaming.
- Pat mushrooms dry before slicing so they sear nicely and do not turn watery.
- Cook frozen udon straight from the freezer; do not thaw or it can turn mushy.
- Undercook shelf-stable or dried udon by 1 minute, then finish it in the sauce.
- Stir miso into a small amount of warm broth first so it dissolves smoothly.
- Add cream after the mushrooms and broth simmer so it stays silky and does not curdle.
- Taste before adding extra salt because soy sauce, miso, and broth already bring saltiness.
- Keep the sauce a little looser than you think; udon drinks it up as it sits.
- Slice mushrooms in different shapes and sizes for better texture in every bite.
- Add a handful of spinach or baby bok choy at the end if you want more veggies.
How to Make Creamy Mushroom Udon Recipe
Step 1: Prep noodles and ingredients
Bring a medium pot of water to a boil for the udon. If you use frozen udon, keep it in the freezer until the water boils. Slice mushrooms, onion, carrot, and green onions, and mince garlic and ginger so everything cooks quickly and evenly.
Step 2: Sauté veggies and aromatics
Heat the neutral oil and butter in a large skillet or Dutch oven over medium-high heat. Add the sliced mushrooms in a single layer and let them cook without stirring for 3–4 minutes so they brown. Stir and cook another 3–4 minutes until they turn golden and smell nutty.
Add the sliced onion and carrot to the pan and cook 4–5 minutes until they soften and pick up some color. Stir in garlic, ginger, and the white parts of the green onions. Cook 1–2 minutes until fragrant, then season with a pinch of salt and black pepper.
Step 3: Build the savory sauce
Lower the heat to medium. Add soy sauce, oyster or mushroom sauce, mirin, sesame oil, and red pepper flakes if you use them. Stir well and scrape up any browned bits from the bottom of the pan.
Pour in the broth and bring the mixture to a gentle simmer. In a small bowl, whisk the miso with a few spoonfuls of hot broth from the pan until smooth, then stir that back into the skillet. Let the sauce simmer 3–4 minutes so the flavors deepen and the liquid reduces slightly.
Step 4: Cook the udon
While the sauce simmers, cook the udon.
- Frozen udon: Add directly to boiling water and cook 1–2 minutes until just loosened and tender, then drain.
- Shelf-stable or dried udon: Cook according to package directions, but pull the noodles 1 minute early so they stay firm.
Rinse the noodles quickly under hot water to remove excess starch, then drain well. Keep them nearby so you can add them straight into the sauce while they are still hot.
Step 5: Add the cream
Turn the heat under the mushroom mixture to low. Pour in the cream or half-and-half and stir until the sauce turns pale and silky. Taste and adjust seasoning with more soy sauce, pepper, or a pinch of salt if needed.
Let the sauce bubble gently for 2–3 minutes so it thickens slightly. You want it to coat the back of a spoon but still run easily, like a loose Alfredo. If it thickens too much, splash in a bit more broth.
Step 6: Toss noodles in the sauce
Add the hot udon noodles straight into the skillet. Use tongs or chopsticks to toss until every strand coats with the creamy mushroom sauce. The noodles will drink up some liquid, so add a spoonful of broth or a splash of hot water if the pan looks dry.
Stir in the green parts of the green onions, saving a little for garnish. Taste one noodle and adjust seasoning again if needed. Turn off the heat so the sauce stays creamy and the noodles do not overcook.
Step 7: Plate and garnish
Divide the Creamy Mushroom Udon Recipe into bowls while everything stays hot and glossy. Top with extra green onions, toasted sesame seeds, and a drizzle of chili crisp if you like heat. Add nori strips or a sprinkle of furikake for extra umami, and finish with a tiny squeeze of lime or lemon for brightness.
Serve right away while the noodles stay bouncy and the sauce tastes rich and silky.
What to Serve with Creamy Mushroom Udon Recipe
Serve this Creamy Mushroom Udon Recipe with a crisp cucumber salad, lightly dressed with rice vinegar, sesame oil, and a pinch of sugar. A side of steamed edamame with sea salt pairs nicely and adds extra protein. You can also add a simple pan-seared tofu or teriyaki-style chicken on the side if you want more substance. If you crave more veggies, toss together a quick sesame slaw with cabbage, carrots, and green onions.
Storage Options
- Store leftovers in an airtight container in the fridge for up to 3 days; the noodles will soften but still taste great.
- Add a splash of broth or milk before reheating so the sauce loosens and turns creamy again.
- Reheat gently on the stovetop over low heat, stirring often, or in the microwave at 50–70 percent power in short bursts.
- Freeze only the mushroom sauce without noodles for up to 2 months, then thaw in the fridge and add freshly cooked udon when you reheat.
