Creamy Mushroom Udon Recipe tastes like ultra-cozy, slurpable comfort with chewy noodles, rich umami cream sauce, and buttery mushrooms in every bite. It works perfectly for busy weeknights or lazy weekends, since you can get it on the table in about 25 minutes. I first made a version of this on a cold Chicago night, and my husband still asks for “that mushroom noodle thing” weekly.
Why Creamy Mushroom Udon Recipe Is Worth It
You get the best of both worlds: the chew of Japanese udon noodles and the richness of a creamy mushroom sauce that feels like upgraded mac and cheese. The sauce hugs every noodle, and the mushrooms bring deep savory flavor that tastes like you simmered it for hours.
This recipe also uses easy pantry shortcuts, so you cook it even when the fridge looks sad. You only need one pan plus a pot for noodles, and the whole thing tastes like takeout-level comfort with home-cooked control over salt and creaminess.

Ingredients You Need
Udon noodles
- 2 packs frozen udon noodles
- I like frozen over dried, since they stay extra chewy.
- Use shelf-stable udon if needed; just cook 1 to 2 minutes less than package directions so they stay bouncy.
Mushrooms
- 8 ounces cremini mushrooms, sliced
- 4 ounces shiitake mushrooms, stems removed, caps sliced
- Use any mix: button, oyster, maitake, or even portobello.
- If you only have one kind, that still works; just bump the amount to 12 ounces total.
Aromatics
- 2 tablespoons unsalted butter
- 1 tablespoon neutral oil (canola, avocado, or light olive oil)
- 3 cloves garlic, minced
- 1 small shallot, finely minced
- Use 2 to 3 green onions if you do not have shallot.
Sauce base
- 1 cup low sodium vegetable broth or chicken broth
- 1 tablespoon soy sauce
- 1 tablespoon oyster sauce or vegetarian mushroom stir fry sauce
- 1 teaspoon mirin or a pinch of sugar
- 1 teaspoon toasted sesame oil
Creamy element
- 3/4 cup heavy cream
- Swap with half and half for a lighter version, or use 2/3 cup whole milk plus 1 tablespoon cream cheese.
- 2 tablespoons grated Parmesan or finely grated pecorino
- Use an Asian-style parmesan blend if you find it; it melts nicely and tastes mild.
Seasoning
- 1/4 teaspoon black pepper
- 1/4 teaspoon white pepper (optional but tasty)
- Salt to taste
- Pinch of red pepper flakes or shichimi togarashi for heat
Toppings
- 2 green onions, thinly sliced
- Toasted sesame seeds
- Chili crisp or chili oil, to taste
- Soft boiled egg or jammy egg, optional
- A squeeze of lemon or yuzu juice, optional, to brighten the richness
Pantry shortcuts
- Use pre-sliced mushrooms to save time.
- Use jarred minced garlic and frozen chopped onions if you feel tired.
- Use frozen pre-cooked udon bricks; they go straight from freezer to boiling water.
Equipment list
- Large skillet or sauté pan (10 to 12 inch)
- Medium pot for boiling udon
- Tongs or chopsticks for noodles
- Wooden spoon or spatula
- Small bowl and whisk for mixing sauce ingredients
Quick Tips & substitutions
- Boil udon until just shy of done, since they finish in the sauce.
- Dry the mushrooms with a paper towel so they brown instead of steaming.
- Cook mushrooms in a single layer and avoid crowding the pan for best color and flavor.
- Use all cremini or all button mushrooms if that is what you have.
- Swap heavy cream with coconut cream for a dairy free twist.
- Use gluten free tamari and gluten free udon or thick rice noodles if you avoid gluten.
- Stir the sauce often once you add cream so it stays silky and does not scorch.
- Thin a too-thick sauce with a splash of noodle cooking water.
- Thicken a too-thin sauce by simmering 1 to 2 minutes more on low heat.
- Taste and adjust soy sauce and salt at the end, since broth and cheese already add salt.
How to Make Creamy Mushroom Udon Recipe
Step 1: Prep noodles and ingredients
Bring a medium pot of water to a boil and keep it at a gentle simmer while you prep.
Slice mushrooms, mince garlic and shallot, and slice green onions.
Mix broth, soy sauce, oyster sauce, mirin, and sesame oil in a small bowl so you can add it quickly later.
Step 2: Cook the udon
Add frozen udon to the simmering water and loosen the bricks with chopsticks or tongs.
Cook 1 to 2 minutes less than package directions so the noodles stay firm.
Drain the noodles, rinse briefly with warm water to remove extra starch, and set aside; toss with a tiny drizzle of oil if they stick.
Step 3: Brown the mushrooms
Heat the large skillet over medium high heat and add the oil and 1 tablespoon of butter.
Add mushrooms in a single layer and leave them alone for 3 to 4 minutes so they brown.
Stir and continue to cook 3 to 4 more minutes until the mushrooms shrink and turn golden around the edges.
Step 4: Add aromatics
Lower the heat to medium.
Add the remaining 1 tablespoon of butter, then add shallot and cook 1 to 2 minutes until it softens and turns fragrant.
Add garlic and cook 30 seconds until it smells garlicky but not burnt.
Step 5: Build the sauce
Pour in the broth mixture and scrape the bottom of the pan to pick up browned bits.
Let the mixture simmer for 2 to 3 minutes so the flavors concentrate slightly.
Stir in the heavy cream and bring the sauce back to a gentle simmer, not a hard boil.
Step 6: Season and add cheese
Add black pepper, white pepper, and red pepper flakes or shichimi if you use it.
Sprinkle in the Parmesan and stir until it melts and the sauce turns glossy and creamy.
Taste and adjust with a pinch of salt or a few extra drops of soy sauce if needed.
Step 7: Add udon and coat
Add the cooked udon noodles straight into the skillet.
Use tongs to toss the noodles in the creamy mushroom sauce until every strand looks coated.
If the sauce looks too thick, add a splash of hot water from the tap or leftover broth until it reaches your ideal consistency.
Step 8: Finish and serve
Turn off the heat and add a small squeeze of lemon or yuzu if you like a hint of brightness.
Top the noodles with sliced green onions, toasted sesame seeds, and a drizzle of chili crisp.
Add a soft boiled egg on top for extra richness, then serve hot while the noodles stay bouncy and the sauce stays silky.
Recipe Variations
- Gluten free: Use gluten free udon or thick rice noodles and swap soy sauce with tamari and oyster sauce with a gluten free mushroom sauce.
- Vegan: Use vegan butter or neutral oil, coconut cream or cashew cream, and a vegan mushroom stir fry sauce instead of oyster sauce; skip cheese or use vegan parmesan.
- Lighter version: Use half and half instead of heavy cream and reduce cheese to 1 tablespoon.
- Extra protein: Add sautéed tofu cubes, rotisserie chicken, or shredded cooked chicken breast.
- Extra veggies: Toss in baby spinach, bok choy, snap peas, or thinly sliced carrots during the last 2 minutes of simmering.
- Spicy version: Add more chili crisp, a spoon of gochujang, or a sprinkle of extra shichimi togarashi.
Ways to Serve
- Serve in deep bowls with extra broth on the side for those who like it saucy.
- Add a side of cucumber salad with rice vinegar and sesame for crunch and freshness.
- Pair with miso soup or simple veggie broth for a full noodle night.
- Top with extra green onions, nori strips, and sesame seeds for a ramen shop vibe.
- Pack leftovers in a thermos for a warm work or school lunch.
Storage Success
Store leftover creamy mushroom udon in an airtight container in the fridge for up to 3 days. The noodles soak up sauce as they sit, so add a splash of milk, cream, or broth when you reheat. Reheat gently on the stove over low heat or in the microwave in short bursts, stirring between each round so the sauce turns smooth again. I do not suggest freezing this recipe, since the cream can separate and the udon can lose its chewy texture.
Creamy Mushroom Udon Recipe
Ingredients
Method
- Bring a medium pot of water to a boil, then keep it at a gentle simmer while you prep the other ingredients.
- Slice the cremini and shiitake mushrooms, mince the garlic and shallot, and thinly slice the green onions. In a small bowl, whisk together the broth, soy sauce, oyster sauce, mirin (or pinch of sugar), and toasted sesame oil; set aside.
- Add the frozen udon noodles to the simmering water. Loosen the bricks with chopsticks or tongs and cook 1 to 2 minutes less than the package directions, just until the noodles are almost tender but still firm.
- Drain the noodles, rinse briefly with warm water to remove excess starch, and set aside. If they stick together, toss with a tiny drizzle of neutral oil.
- Heat a large skillet over medium-high heat. Add the neutral oil and 1 tablespoon of the butter. When hot, add the sliced mushrooms in a single layer. Let them cook undisturbed for 3 to 4 minutes so they brown well on one side.
- Stir the mushrooms and continue cooking for another 3 to 4 minutes, until they have shrunk and turned golden around the edges.
- Reduce the heat to medium. Add the remaining 1 tablespoon of butter and the minced shallot. Cook, stirring, for 1 to 2 minutes until the shallot softens and smells fragrant.
- Add the minced garlic and cook for about 30 seconds, just until fragrant but not browned.
- Pour the broth mixture into the skillet and stir, scraping up any browned bits from the bottom of the pan. Let the mixture simmer for 2 to 3 minutes to slightly concentrate the flavors.
- Stir in the heavy cream and bring the sauce back to a gentle simmer, avoiding a hard boil so the cream stays smooth.
- Season the sauce with black pepper, white pepper if using, and a pinch of red pepper flakes or shichimi togarashi if you like heat. Sprinkle in the grated Parmesan and stir until it melts and the sauce turns glossy and creamy. Taste and adjust with a little salt or extra soy sauce if needed.
- Add the cooked udon noodles directly to the skillet. Use tongs to toss the noodles in the creamy mushroom sauce until every strand is well coated. If the sauce seems too thick, add a splash of hot water or extra broth to loosen it slightly.
- Turn off the heat and finish with a small squeeze of lemon or yuzu juice if you prefer a brighter flavor. Divide the noodles into bowls and top with sliced green onions, toasted sesame seeds, and a drizzle of chili crisp or chili oil if desired. Add a soft boiled or jammy egg on top for extra richness and serve hot.
