Ingredients
- 2 servings (about 7 oz / 200 g) fresh or frozen udon noodles (or 5.6 oz / 160 g dried udon)
- 2 tbsp (30 ml) soy sauce
- 1 tbsp (15 ml) mirin
- 1 tbsp (15 ml) oyster sauce (or vegetarian stir-fry sauce)
- 1 tsp (5 ml) toasted sesame oil
- 1 tsp (5 g) sugar
- 1 tbsp (15 ml) neutral oil (like canola or vegetable), divided
- 1 small onion, thinly sliced (about 1 cup / 100 g)
- 1 bell pepper, thinly sliced (about 1 cup / 150 g)
- 2 cloves garlic, minced
- 1 small carrot, julienned (about 1/2 cup / 60 g)
- 3 oz (85 g) shiitake or cremini mushrooms, sliced
- 2 green onions, sliced, for garnish
- Optional: 1 tsp (5 g) sesame seeds, for garnish
- Optional protein: 1 cup (150 g) cooked chicken, beef, or tofu, sliced
Instructions
- Prepare the noodles: If using fresh or frozen udon, bring a pot of water to a boil. Add the noodles and cook for 1–2 minutes (or according to package instructions) until just tender but still chewy. Drain and rinse briefly under cold water to stop cooking. If using dried udon, cook according to package directions until al dente. Set aside.
- Make the sauce: In a small bowl, whisk together soy sauce, mirin, oyster sauce, sesame oil, and sugar until the sugar dissolves. Set aside.
- Heat the pan: Heat 1 tbsp (15 ml) of neutral oil in a large skillet or wok over high heat until shimmering. If adding protein, add it now and stir-fry for 2–3 minutes until heated through (if using cooked meat) or until cooked to safe internal temperature (see note). Remove and set aside.
- Cook the vegetables: Add the remaining 1 tbsp (15 ml) oil to the pan. Add onion, bell pepper, carrot, and mushrooms. Stir-fry for 3–4 minutes until the vegetables are tender-crisp. Add garlic and cook for 30 seconds until fragrant.
- Combine and sauce: Add the cooked noodles and the sauce to the pan. Toss everything together with tongs, making sure the noodles are well coated. If using protein, add it back now. Cook for 1–2 minutes, letting the sauce slightly caramelize on the noodles.
- Finish and serve: Remove from heat. Garnish with sliced green onions and sesame seeds if using. Serve immediately.
Note: If adding raw chicken, cook until the internal temperature reaches 165°F (74°C) (USDA FSIS safe minimum). For ground meat, cook to 160°F (71°C).
Tips
- Noodle prep: Fresh or frozen udon are ideal; they have the right chewy texture. If using dried, cook slightly less than package directions to keep them firm.
- High heat: Stir-frying over high heat gives the noodles a slight char and prevents sogginess. Don’t overcrowd the pan—cook in batches if needed.
- Substitutions: No mirin? Use 1 tsp rice vinegar + 1/2 tsp sugar. No oyster sauce? Use hoisin or a splash of vegan Worcestershire sauce. Swap vegetables based on what’s in your fridge—cabbage, broccoli, or snap peas work well.
- Common mistake: Overcooking the noodles makes them mushy. Keep the total stir-fry time short after adding noodles.
Serving Suggestions
Serve the udon as a complete meal in a bowl, topped with extra green onions, a drizzle of chili oil, or a sprinkle of shichimi togarashi for heat. Pair with a simple cucumber salad or miso soup for a fuller Japanese-inspired dinner. For a protein boost, add a soft-boiled egg or a side of grilled chicken.
Variations
- Spicy: Add 1–2 tsp of gochujang or sriracha to the sauce for a kick.
- Vegetarian: Use mushroom-based oyster sauce or skip it, and add extra mushrooms or tofu.
- Protein-packed: Include sliced beef (cook to 145°F/63°C for medium-rare, or 160°F/71°C for ground), shrimp (cook until pink and opaque), or tofu.
- Peanut sauce: Replace the sauce with 2 tbsp peanut butter, 1 tbsp soy sauce, 1 tbsp rice vinegar, 1 tsp honey, and 2 tbsp water for a Thai-inspired twist.
Storage and Reheating
Refrigerate leftovers in an airtight container for up to 3 days. To reheat, place in a hot skillet with a splash of water or soy sauce over medium-high heat, tossing until heated through—this revives the texture better than microwaving. If using a microwave, cover and heat in 30-second bursts, stirring in between. Do not freeze, as udon can become mushy when thawed.
Frequently Asked Questions
Can I use instant ramen noodles instead of udon? Yes, but the texture will be different. Instant ramen is thinner and less chewy; cook it briefly and drain well before stir-frying. The sauce will still taste great.
What if I don’t have mirin? Mix 1 tsp rice vinegar with 1/2 tsp sugar as a substitute. Alternatively, use a dry sherry or white wine.
Can I make this gluten-free? Use tamari or gluten-free soy sauce, and choose gluten-free noodles like soba (buckwheat) or rice noodles. Check that your oyster sauce is gluten-free or substitute with hoisin.
Why are my noodles sticking together? This happens if they’re not drained well or if you let them sit too long. Rinse them after boiling to remove excess starch, and toss with a little oil if not using immediately.
Can I add raw meat directly to the stir-fry? Yes, but cook it first in the hot pan until it reaches a safe internal temperature—165°F (74°C) for chicken, 160°F (71°C) for ground meat, or 145°F (63°C) for whole cuts of beef or pork. Remove and set aside, then add back at the end.
Is this dish authentic Japanese street food? Yaki udon is a popular home-style and street food in Japan, but this recipe is a simplified, adaptable version. Authentic versions often include fish cake (kamaboko) and cabbage, but the core technique is the same.
