It’s a perfect way to enjoy high-quality beef without overcomplicating it.
Ingredients
- 1 lb (450 g) Wagyu beef (ribeye or sirloin), thinly sliced
- 2 packs (about 14 oz / 400 g) fresh udon noodles (or 8 oz / 225 g dried)
- 2 tbsp (30 ml) vegetable oil, divided
- 1 cup (150 g) broccoli florets
- 1 red bell pepper, thinly sliced
- 2 carrots, julienned
- 4 green onions, sliced, white and green parts separated
- 2 cloves garlic, minced
- 1 tbsp (15 ml) fresh ginger, grated
- 1/4 cup (60 ml) low-sodium soy sauce
- 2 tbsp (30 ml) mirin
- 1 tbsp (15 ml) rice vinegar
- 1 tsp (5 ml) sesame oil
- 1 tsp (5 g) brown sugar
- 1 tbsp (8 g) sesame seeds, for garnish
- Salt and freshly ground black pepper, to taste
Instructions
- Pat the Wagyu beef dry with paper towels. Season lightly with salt and pepper. If using a whole cut, place it in the freezer for 15 minutes to firm up, then slice thinly against the grain. If using pre-sliced, skip this step.
- In a small bowl, whisk together soy sauce, mirin, rice vinegar, sesame oil, and brown sugar. Set aside.
- Cook the udon noodles according to package instructions (usually 2-3 minutes in boiling water). Drain, rinse under cold water, and set aside.
- Heat 1 tbsp (15 ml) vegetable oil in a large skillet or wok over high heat. Add the broccoli, bell pepper, and carrots. Stir-fry for 3-4 minutes until crisp-tender. Remove vegetables from the pan and set aside.
- Add the remaining 1 tbsp (15 ml) vegetable oil to the same pan. Add the white parts of the green onions, garlic, and ginger. Stir-fry for 30 seconds until fragrant.
- Add the sliced Wagyu beef in a single layer. Sear for 1-2 minutes per side until browned but still pink inside. For medium-rare, the internal temperature should reach 145°F (63°C) (USDA FSIS safe minimum for whole cuts of beef) with a 3-minute rest. Do not overcook; Wagyu is best enjoyed medium-rare.
- Pour the sauce over the beef and let it bubble for 30 seconds, scraping up any browned bits.
- Return the vegetables to the pan, add the cooked noodles, and toss everything together for 1-2 minutes until heated through and well coated.
- Remove from heat. Garnish with the green parts of the green onions and sesame seeds. Serve immediately.
Tips
- Substitutions: If you can’t find Wagyu, use a well-marbled ribeye or sirloin. For a budget-friendly option, use flank steak. You can swap udon with soba noodles or rice noodles.
- Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet with a splash of water or soy sauce to revive the sauce.
- Common mistake: Overcooking Wagyu is the biggest mistake. The high fat content means it cooks quickly; keep the heat high and cook briefly. Also, don’t overcrowd the pan when searing the beef—do it in batches if needed to get a good sear.
- Noodle prep: If using dried udon, cook them al dente as they will continue to cook when tossed with the beef and sauce.
Serving Suggestions
Serve this bowl as a complete meal. For added freshness, top with a squeeze of lime juice or a sprinkle of chili flakes for heat. A side of pickled ginger or a simple cucumber salad would complement the richness of the beef. For a more substantial meal, add a soft-boiled egg on top.
Variations
- Spicy: Add 1-2 tsp (5-10 g) of gochujang or sriracha to the sauce for a kick.
- Vegetable-forward: Add mushrooms, snap peas, or baby corn along with the other vegetables.
- Gluten-free: Use tamari instead of soy sauce, and choose gluten-free noodles like rice noodles or soba (check label).
- Teriyaki-style: Increase the brown sugar to 2 tbsp (25 g) and add 1 tbsp (15 ml) of honey for a sweeter, stickier glaze.
Storage and Reheating
Refrigerate leftovers within 2 hours of cooking. Store in an airtight container for up to 3 days. To reheat, place in a skillet over medium heat with a splash of water or soy sauce, stirring until heated through (about 3-4 minutes). Alternatively, microwave in 30-second intervals, stirring in between, until hot. Avoid reheating more than once to preserve texture. Freezing is not recommended as the noodles and vegetables will become mushy.
Frequently Asked Questions
Can I use a different cut of beef? Yes, any well-marbled steak works. Look for ribeye, sirloin, or even New York strip. If using a leaner cut, consider marinating the slices in a bit of soy sauce and sesame oil for 15 minutes to add flavor and tenderness.
How do I slice Wagyu thinly without it falling apart? Freeze the steak for 15-20 minutes before slicing. This firms up the fat and makes it easier to cut thin, even slices. Use a sharp knife and slice against the grain for maximum tenderness.
Can I make this ahead of time? You can prep all the ingredients (slice vegetables, make sauce, cook noodles) up to a day in advance. Store separately in the fridge. Cook the beef and assemble just before serving to keep the textures fresh.
What if I don’t have mirin? Mix 1 tbsp (15 ml) rice vinegar with 1 tsp (5 g) sugar as a substitute. It won’t be exactly the same but will add the necessary sweetness and acidity.
Is Wagyu beef safe to eat medium-rare? Yes, as long as it’s a whole cut (not ground). The USDA FSIS recommends cooking whole cuts of beef to 145°F (63°C) with a 3-minute rest. Use a meat thermometer to check the temperature in the thickest part.
Can I use frozen udon noodles? Absolutely. Frozen udon are actually great—just boil them for 1-2 minutes (or as directed on the package) to separate and heat through. They have a nice chewy texture.
