15 min Creamy Mushroom Udon
If you’re looking for a cozy, comforting bowl of noodles that also feels nourishing, this Creamy Lion’s Mane Mushroom Udon is one of those recipes that hits every time. It’s rich, savory, and umami-packed, with a velvety sauce that clings perfectly to chewy udon noodles.
Lion’s mane mushrooms have a naturally meaty, almost seafood-like texture, making them the perfect star for a creamy pasta-style dish without needing any actual meat. When sautéed, they become golden on the edges, slightly crisp, and incredibly flavorful, absorbing sauces beautifully while adding their own subtle sweetness.
Paired with a creamy base, the mushrooms create a dish that feels indulgent but still light enough to enjoy any day of the week. It’s the kind of meal that tastes elevated, but comes together simply with just a few ingredients.

Substitutions & Variations
Lion’s Mane Mushrooms- If you can’t find lion’s mane, you can substitute with oyster mushrooms, shiitake, or a mix of mushrooms. Oyster mushrooms are the closest in texture and will still give that soft, slightly “meaty” bite.
King Trumpet Mushrooms- King trumpet mushrooms can be swapped with cremini, portobello, or even more oyster mushrooms. They add a firm, chewy texture, so try to use a mushroom with some structure.
Half-and-Half or Heavy Cream- You can use either depending on how rich you want the dish. For a lighter option, substitute with whole milk or evaporated milk (the sauce will be thinner). For dairy-free, try full-fat coconut milk or cashew cream.
Udon Water or Broth- Udon cooking water helps thicken the sauce with starch, but chicken broth adds extra flavor. You can also use vegetable broth for a fully vegetarian version.
Add Protein- You can add shrimp, bacon, or tofu to make the dish more filling.
Add Greens- Spinach, kale, or peas can be added at the end for extra color and freshness.
Cheese Options-Freshly grated parmesan works best, but pecorino or even a mild shredded cheese can add extra creaminess and saltiness.
Storage & Reheating
Storage: Store leftovers in an airtight container in the refrigerator for up to 2–3 days.
Reheating: Reheat gently on the stove over medium-low heat. Add a splash of water, broth, or milk to loosen the sauce as it thickens in the fridge.
Microwave Option: Reheat in short intervals, stirring in between, and add a little liquid to keep the noodles from drying out.
Freezing: This dish is best enjoyed fresh. Cream-based sauces can separate after freezing, and the udon texture may become too soft once thawed.
Ingredients
Udon- Udon noodles are thick, chewy, and perfect for holding onto creamy sauces. Their texture makes the dish feel extra comforting and hearty.
Lion’s Mane Mushrooms- Lion’s mane has a tender, slightly fibrous texture that mimics seafood. It absorbs the sauce well while adding a subtle sweetness and deep umami flavor.
King Trumpet Mushrooms- These mushrooms add a firmer, meatier bite that balances the softness of the udon and lion’s mane. They also soak up flavor while keeping their structure.
Garlic- Garlic builds the base flavor of the dish. When sautéed, it adds warmth and aroma that enhances the creaminess of the sauce.
Half-and-Half or Heavy Cream- This creates the creamy base of the sauce. Heavy cream gives a richer, thicker texture, while half-and-half keeps it lighter but still smooth.
Udon Water or Chicken Broth- Udon water contains starch that helps emulsify the sauce so it clings to the noodles. Chicken broth adds extra depth and savory flavor.
Salt, Black Pepper, and Garlic Powder- These seasonings balance and enhance the overall flavor. Garlic powder adds an extra layer of savory depth alongside fresh garlic.
Freshly Grated Cheese (Optional)- Cheese adds saltiness, richness, and helps thicken the sauce slightly, making it more cohesive and creamy.
Ingredients:
1 pack udon
3 oz lions mane
3 oz king trumpet mushrooms
2-3 garlic cloves (sliced)
1/2 cup half & half or heavy cream
1/2 cup udon water or chicken broth
salt, black pepper, and garlic powder taste
optional- freshly grated cheese
Directions:
Boil udon according to package instructions. Reserve about ½ cup udon water, then drain and set aside.
In a pan, add butter, garlic, lion’s mane, and king trumpet mushrooms, spreading them out so they can sear. Cook until lightly golden and the moisture releases and evaporates (about 4–5 minutes).
Season with salt to draw out moisture from mushrooms while sautéing, which contributes to the natural umami and slightly caramelized texture.
Pour in half-and-half (or heavy cream) and udon water (or broth). Stir and let it simmer gently for 2–3 minutes until slightly thickened.
Season with salt, black pepper, and garlic powder, then mix.
Add the cooked udon and toss well so the noodles are fully coated in the sauce.
Taste and adjust seasoning if needed.
Turn off heat and finish with freshly grated cheese if using.
