How to Make Black Pepper Beef Udon Stir-Fry

Step 1: Marinate the Beef

In a bowl, whisk together minced garlic, sesame oil, soy sauce, oyster sauce, vinegar, and a slurry of cornstarch with water.

Add the sliced beef, toss well to coat, and let it marinate for 10 minutes while you prep the rest.

Step 2: Prep the Udon Noodles

Boil a large pot of water.

Add udon noodles and cook for 1–2 minutes just until they loosen.

Drain immediately and set aside.

Don’t overcook—you want them slightly chewy.

Step 3: Make the Black Pepper Sauce

In a small bowl, combine dark soy sauce, oyster sauce, ground black pepper, water, and potato starch.

Stir well to dissolve the starch completely.

Step 4: Sauté Aromatics & Beef

Heat a bit of oil in a wok or large pan over medium heat.

Add garlic and sliced onions, sautéing until soft and fragrant.

Add the marinated beef and stir-fry for 2–3 minutes until browned and mostly cooked through.

Step 5: Add Sauce & Noodles

Pour the black pepper sauce into the wok.

Stir gently over low heat until the sauce thickens and turns glossy.

Add cooked udon and chopped Chinese cabbage.

Toss everything together to coat well in the sauce.

Step 6: Serve Hot

Taste and adjust with a pinch of salt or sugar if needed.

Serve immediately while everything is still piping hot and glossy!

What to Serve It With

A light cucumber salad with vinegar

Kimchi or pickled radish

Miso soup or seaweed soup

A fried egg on top for extra indulgence

Variations / Substitutions

Swap beef: Use chicken, pork, or tofu instead.

Change greens: Try spinach, bok choy, or kale.

Add veggies: Mushrooms, bell peppers, or shredded carrots work well.

Noodle swap: Soba, ramen, or rice noodles also pair well with the sauce.

Make it spicy: Add chili oil or Sriracha to the sauce.

Storage & Leftovers

Store leftovers in an airtight container in the fridge for up to 3 days.

Reheat in a pan over low heat with a splash of water or broth.

Noodles may absorb the sauce over time, so freshen with a little soy or oyster sauce before reheating.

Not freezer-friendly—the udon may get mushy.
