Ingredients You’ll Need
Udon and Beef
-
14 to 16 ounces fresh or frozen udon noodles
- Use vacuum-packed “sanuki” style udon for the best chewy texture.
- If you only have dried udon, cook it 1 to 2 minutes less than package directions so it stays firm in the stir fry.
-
3/4 to 1 pound beef, thinly sliced
- Flank steak, sirloin, or ribeye work great.
- Ask the butcher to slice it thin, or partially freeze the beef for 20 minutes and slice it yourself.
Vegetables
- 1 medium onion, thinly sliced
- 1 cup shredded carrot or matchstick carrots
- Pre-shredded bagged carrots save time and work perfectly.
- 1 red bell pepper, thinly sliced
- 2 cups broccoli florets, small bite-size pieces
- 3 to 4 green onions, sliced (separate white and green parts)
- 2 to 3 cloves garlic, minced
- 1 teaspoon fresh ginger, grated or very finely minced
- Use ginger paste from a tube if you want a shortcut.
Sauce
- 1/4 cup low sodium soy sauce
- 2 tablespoons oyster sauce
- Lee Kum Kee or Kikkoman oyster sauce both give rich flavor.
- 1 tablespoon dark soy sauce (optional, for deeper color and flavor)
- 1 to 2 tablespoons brown sugar
- 1 tablespoon mirin or seasoned rice vinegar
- 1 tablespoon sesame oil
- 1/4 cup water or low sodium beef broth
- 1 to 1 1/2 teaspoons cornstarch
Stir Fry & Garnish
- 2 to 3 tablespoons neutral oil (canola, avocado, or vegetable oil)
- 1 teaspoon toasted sesame seeds
- Extra soy sauce to taste
- Chili flakes or a drizzle of chili oil, optional
Substitutions & Variations
- Swap beef with thinly sliced chicken thighs or pork if you prefer.
- Use snap peas, mushrooms, or baby bok choy instead of broccoli or bell pepper.
- Use tamari or coconut aminos in place of soy sauce for a lower gluten option.
- Add a soft boiled egg on top for extra protein and richness.
Equipment List
- Large nonstick skillet or wok
- Cutting board and sharp knife
- Tongs or a sturdy spatula
- Small bowl and whisk for the sauce
- Medium pot for cooking dried udon, if you use dried noodles
Tips & Tricks
- Slice beef very thin so it cooks quickly and stays tender.
- Pat beef dry with paper towels so it browns instead of steaming.
- Do all chopping and sauce mixing before you heat the pan, since stir fry moves fast.
- Use high heat so vegetables stay crisp and noodles pick up a bit of char.
- Loosen fresh or frozen udon in hot water for 1 to 2 minutes so the strands separate easily.
- Do not overcrowd the pan; cook beef in two batches if needed.
- Taste the sauce before you add it and adjust salt or sweetness to your liking.
- Keep noodles slightly undercooked if you use dried udon, since they finish in the pan.
- Add a splash of water or broth if the noodles look dry while you stir fry.
- Finish with sesame oil at the end so the flavor stays bright and nutty.
How to Make Tasty Beef Udon Stir Fry Recipe
Step 1: Mix the Sauce
Add soy sauce, oyster sauce, dark soy sauce, brown sugar, mirin or rice vinegar, sesame oil, water or broth, and cornstarch to a small bowl. Whisk until the sugar and cornstarch dissolve completely. Taste and adjust sweetness or saltiness, then set the bowl aside.
Step 2: Prep the Noodles
If you use fresh or frozen udon, place the blocks of noodles in a bowl and cover them with very hot tap water. Gently separate the strands with chopsticks or tongs, then drain and set aside. If you use dried udon, cook it in boiling water until just shy of tender, drain, rinse briefly under cool water, and toss with a teaspoon of oil to prevent sticking.
Step 3: Prep the Beef and Vegetables
Slice the beef thinly across the grain into bite-size strips. Pat the slices dry with paper towels and season lightly with salt and pepper. Slice the onion, bell pepper, and green onions, and cut the broccoli into small florets so everything cooks quickly.
Step 4: Sear the Beef
Heat 1 tablespoon of oil in a large skillet or wok over medium high heat until it shimmers. Add half the beef in a single layer and let it sear for about 1 minute before you stir. Stir fry another 1 to 2 minutes until the beef looks mostly cooked with some browned edges, then transfer it to a plate and repeat with the remaining beef.
Step 5: Stir Fry the Vegetables
Add another tablespoon of oil to the same pan if it looks dry. Add onion, carrot, and bell pepper, and stir fry 2 to 3 minutes until they start to soften but still feel crisp. Add broccoli florets and the white parts of the green onions, and cook 2 to 3 more minutes.
Step 6: Add Aromatics
Push the vegetables to the sides of the pan and add a small drizzle of oil to the center. Add garlic and ginger to the center and stir for 30 seconds until they smell fragrant. Toss everything together so the aromatics coat the vegetables evenly.
Step 7: Combine Beef and Noodles
Return the cooked beef and any juices from the plate to the pan. Add the drained udon noodles on top. Use tongs to lift and toss the noodles with the beef and vegetables until everything looks mixed.
Step 8: Add Sauce and Finish
Give the sauce a quick stir, then pour it evenly over the noodles. Toss constantly for 2 to 4 minutes over medium high heat until the sauce thickens slightly and coats the noodles with a glossy finish. Sprinkle in the green parts of the green onions and sesame seeds, toss again, and taste to see if you want extra soy sauce or chili flakes.
Step 9: Serve
Turn off the heat and let the stir fry sit for 1 minute so the noodles absorb a bit more sauce. Portion the Tasty Beef Udon Stir Fry Recipe into bowls. Top with extra green onions, sesame seeds, and a drizzle of chili oil if you like heat, then serve hot.
What to Serve with Tasty Beef Udon Stir Fry Recipe
Serve this Tasty Beef Udon Stir Fry Recipe with a simple cucumber salad, dressed with rice vinegar, a pinch of sugar, and sesame seeds. Steamed edamame with a sprinkle of salt also pairs nicely and adds extra protein. A side of miso soup or a clear vegetable broth rounds out the meal without much extra work. For drinks, try iced green tea, jasmine tea, or sparkling water with lemon.
Storage Options
- Store leftovers in an airtight container in the fridge for up to 3 days.
- Reheat gently in a skillet over medium heat with a splash of water or broth until hot, which keeps the noodles from drying out.
- Use the microwave in short bursts, stirring between each burst, and add a teaspoon of water if the noodles look dry.
- Freeze portions in freezer safe containers for up to 2 months, then thaw overnight in the fridge and reheat in a skillet for the best texture.
