Udon Noodle Stir Fry with Mushrooms Recipe hits that perfect spot between cozy and takeout-level tasty, and it comes together in about 25 minutes, so weeknights feel a lot less chaotic. This dish works well for mushroom lovers, busy home cooks, and anyone who wants a satisfying vegetarian stir fry that tastes like it came from a good noodle shop. I first threw this together on a tired Tuesday, and my family now requests it more than my “fancy” weekend dinners.
Why Udon Noodle Stir Fry with Mushrooms Recipe Is Worth It
Thick, chewy udon noodles soak up a glossy soy-garlic sauce, while mushrooms bring deep, savory flavor that tastes almost meaty. The sauce clings to every strand, and the veggies stay crisp-tender, so each bite feels balanced and satisfying.
You cook everything in one large pan or wok, which keeps cleanup easy. Pre-cooked udon bricks and a few pantry staples turn into a restaurant-style noodle stir fry without much effort.
“This Udon Noodle Stir Fry with Mushrooms Recipe tastes like my favorite noodle bar, but I made it in one pan and in less than 30 minutes. ★★★★★”
Ingredients You Need
Udon noodles
- 14–16 oz pre-cooked udon noodles (vacuum-packed or frozen work best; I like frozen Sanuki-style for extra chew)
- If you only find dried udon, use 8–10 oz and cook just until al dente so the noodles stay bouncy in the pan.
Mushrooms
- 8 oz cremini or baby bella mushrooms, sliced
- 4 oz shiitake mushrooms, stems removed, caps sliced (fresh or good-quality dried, rehydrated)
- You can swap in oyster mushrooms or plain white button mushrooms if that’s what you have.
Vegetables
- 1 small yellow onion, thinly sliced
- 1 small carrot, cut into matchsticks or thin half-moons
- 1 red bell pepper, thinly sliced
- 2–3 green onions, sliced (separate white and green parts)
- 2 cups baby spinach or shredded napa cabbage
Aromatics
- 3 cloves garlic, minced
- 1–2 tsp fresh ginger, finely grated or minced
- 1 tsp toasted sesame seeds (optional but tasty)
Stir fry sauce
- 3 tbsp low-sodium soy sauce (or tamari for gluten-free)
- 1 tbsp dark soy sauce (adds color and depth; if you skip it, add 1 extra tsp regular soy)
- 1 tbsp oyster sauce (or mushroom stir fry sauce for a vegetarian option)
- 1 tbsp mirin or mild rice vinegar plus 1/2 tsp sugar
- 1–2 tsp brown sugar or maple syrup, to taste
- 1–2 tsp chili garlic sauce or sriracha, to taste (optional for heat)
- 1/2 cup vegetable broth or water
Thickener and oil
- 1–1.5 tsp cornstarch mixed with 1 tbsp water (slurry)
- 1.5–2 tbsp neutral oil with high smoke point (avocado, canola, grapeseed)
- 1 tsp toasted sesame oil (finish at the end for flavor)
Optional protein add-ins
- 7–8 oz extra-firm tofu, pressed and cubed
- Or thinly sliced chicken thigh or shrimp if you want a non-vegetarian version for other nights
Equipment
- Large nonstick skillet or wok (a wok works best for high heat and tossing)
- Tongs or chopsticks for separating noodles
- Small bowl for sauce
- Cutting board and sharp knife
- Colander if you cook dried udon
Quick Tips & substitutions
- Use frozen or vacuum-packed udon for the best chewy texture; cook dried udon slightly under package time so it stays firm in the stir fry.
- Rinse pre-cooked udon quickly under warm water and loosen with your fingers so the noodles separate easily in the pan.
- Mix the sauce and cornstarch slurry before you start cooking, so you move quickly once the pan heats up.
- Swap soy sauce with tamari and use gluten-free oyster-style mushroom sauce to keep the dish gluten-free.
- Use any mushroom mix you like; shiitake and cremini bring the most umami, but button mushrooms still taste great.
- Add tofu cubes, edamame, or thin-sliced chicken thigh for extra protein; cook the protein first, then set aside and add back with the noodles.
- Keep the pan hot and avoid crowding; cook mushrooms in a single layer so they brown instead of steaming.
- Finish with sesame oil at the end; do not cook it over high heat or the flavor turns bitter.
How to Make Udon Noodle Stir Fry with Mushrooms Recipe
Step 1: Prep noodles and sauce
Run frozen or vacuum-packed udon under warm water and gently separate the strands with your fingers; set them on a plate and pat dry if they feel very wet. If you use dried udon, boil in salted water until just tender, then drain and rinse under cold water to stop the cooking. Toss the drained noodles with a tiny drizzle of neutral oil so they do not clump.
In a small bowl, whisk soy sauce, dark soy, oyster or mushroom sauce, mirin or vinegar, sugar, chili sauce, and broth or water. Taste the sauce and adjust salt, sweetness, and heat to your liking. In another small bowl, stir cornstarch with water until smooth and set it near the stove.
Step 2: Sauté mushrooms and aromatics
Heat 1 tbsp neutral oil in a large skillet or wok over medium-high heat until it shimmers. Add sliced mushrooms in a single layer and leave them alone for 2–3 minutes so they brown on one side. Stir and cook another 2–3 minutes until the mushrooms turn golden and release most of their moisture.
Push mushrooms to the edges of the pan. Add a small splash of oil in the center if the pan looks dry, then add onion, carrot, and the white parts of the green onion. Stir and cook 2–3 minutes until the onion softens slightly but still holds some bite.
Add garlic and ginger and stir constantly for 30–60 seconds until they smell fragrant. Keep the heat at medium-high so the aromatics sizzle but do not burn. Stir the mushrooms back through the aromatics so everything mixes.
Step 3: Add vegetables and noodles
Add bell pepper strips and spinach or napa cabbage to the pan. Toss for 1–2 minutes until the greens wilt and the pepper turns crisp-tender. If the pan feels crowded, lift and toss from the bottom with a spatula or tongs.
Add the udon noodles to the pan. Use tongs or chopsticks to lift and separate the noodles while you mix them with the vegetables and mushrooms. Keep the heat fairly high so the noodles warm through and pick up a bit of color in spots.
Step 4: Sauce and thicken
Give the sauce a quick stir and pour it around the edges of the pan so it hits the hot surface. Toss everything so the noodles and vegetables coat evenly. Stir the cornstarch slurry again and drizzle it into the pan while you toss the noodles.
Cook 1–2 minutes as the sauce bubbles and thickens into a glossy coating on the udon. If the sauce looks too thick, add a splash of broth or water. If it looks too thin, cook another minute while you keep the noodles moving.
Step 5: Finish and serve
Turn off the heat and drizzle sesame oil over the noodles. Toss once more and taste; add a tiny splash of soy sauce or a pinch of sugar if you want more depth or balance. Sprinkle with sesame seeds and the green parts of the green onions.
Serve the Udon Noodle Stir Fry with Mushrooms Recipe hot straight from the pan. Add extra chili sauce on the side for spice lovers. Slurp loudly if you want the full noodle-bar experience.
Recipe Variations
- Gluten-free: Use gluten-free udon or thick rice noodles, swap soy sauce with tamari, and use a gluten-free mushroom-based stir fry sauce instead of regular oyster sauce.
- Vegan: Use mushroom stir fry sauce or extra soy sauce in place of oyster sauce, and stick with vegetable broth and tofu or edamame for protein.
- Low carb-ish: Use shirataki noodles or spiralized zucchini mixed with a smaller portion of udon to cut carbs while keeping some chew.
- Extra protein: Add crispy tofu, tempeh strips, thin-sliced chicken thigh, or shrimp cooked in the same pan before the veggies.
- Spicy version: Add more chili garlic sauce, toss in sliced fresh chilies, or finish with a drizzle of chili crisp.
- Extra veggie: Add snap peas, broccoli florets, bok choy, or bean sprouts during the veggie step for more crunch and color.

Storage Success
Store leftover Udon Noodle Stir Fry with Mushrooms Recipe in an airtight container in the fridge for up to 3 days. Add a teaspoon or two of water or broth before reheating so the noodles loosen and the sauce turns glossy again. Reheat in a skillet over medium heat and toss often, or use the microwave in short bursts and stir between each round. Eat the leftovers hot, since udon noodles taste best when they feel warm and tender, not cold and stiff.
