How to Prepare the Beef for Maximum Tenderness

We marinate the beef lightly to enhance its flavor and texture without overpowering the dish. A quick marinade of soy, sesame oil, and cornstarch helps the beef caramelize beautifully while staying soft. When cooked over high heat, the edges crisp slightly while the inside remains wonderfully tender.

How to Prepare Udon Noodles the Right Way

Fresh udon can clump together, while frozen udon may turn mushy if handled incorrectly. We use a quick blanching method to loosen the noodles without cooking them fully. This ensures they soak in the stir-fry sauce later instead of falling apart.

Step-by-Step Cooking Instructions

1. Marinate the Beef

• Mix the beef with soy sauce, sesame oil, cornstarch, and pepper.
• Let it rest for 10–15 minutes.

2. Prepare the Stir-Fry Sauce

• Combine oyster sauce, soy sauces, sugar, and water in a bowl.
• Adjust saltiness and sweetness to your liking.

3. Blanch the Udon

• Dip noodles into boiling water for 30–40 seconds.
• Drain well and separate gently.

4. Sear the Beef

• Heat a wok until smoking hot.
• Add oil and spread the beef in a single layer.
• Cook just until browned, then remove to avoid overcooking.

5. Stir-Fry the Vegetables

• Add garlic, ginger, and onions.
• Toss in peppers, carrots, and bok choy.
• Stir on high heat until fragrant but crisp.

6. Combine Everything

• Return the beef to the wok.
• Add the udon noodles and pour in the sauce.
• Stir vigorously until the sauce coats every strand.

7. Garnish and Serve

• Top with green onions, sesame seeds, and chili oil.
• Serve hot with optional citrus wedges.

Pro Tips for Perfect Stir-Fry Every Time

• High heat is key: A screaming-hot wok ensures the iconic smoky flavor known as wok hei.
• Avoid overcrowding: Cook beef in batches if needed.
• Balance your flavors: Sweetness, saltiness, and savoriness should dance together—not fight.
• Use fresh udon when possible: Its springy texture makes a noticeable difference.

Serving Suggestions

We love pairing this dish with:

• Quick cucumber salad
• Steamed edamame sprinkled with sea salt
• Hot miso soup
• Green tea or citrus iced tea

These side dishes brighten the meal and add a refreshing contrast to the rich noodles.

How to Store and Reheat Leftovers

We understand how precious good leftovers can be. Store noodles in an airtight container and refrigerate for up to 2 days. Reheat in a pan with a splash of water or broth on medium heat to restore moisture and softness.
