Beef Udon Noodles (Easy 20-Min Recipe Frozen Udon Recipe)
Beef udon noodles (also known as Niku Udon) are the ultimate “cheat code” for a quick dinner after a long 9-5 workday. This Japanese comfort food staple is my go-to (I know I say this a lot) when I need something rich and satisfying without spending an hour in the kitchen. In fact, it can take just 20 minutes!
My favorite shortcut is keeping a pack of frozen udon noodles and thinly sliced hotpot beef rolls in the freezer. It makes this dish a total breeze to throw together. Paired with a simple, savory dashi broth and tender beef, these beef udon noodles feel like a warm hug in a bowl and are ready to eat in just 20 minutes!
What is niku udon?
Niku udon is a classic Japanese noodle dish made with udon noodles and thinly sliced beef simmered or stir-fried in a savory, lightly sweet sauce.
“Niku” means meat in Japanese, and this dish is most commonly made with beef, resulting in what many people know as beef udon noodles. This quick version keeps the cozy flavors of traditional niku udon while using frozen udon noodles for a faster, weeknight-friendly meal.
Pro-tip: Serve with an Onsen Egg
Onsen eggs (温泉卵, onsen tamago) are a traditional Japanese-style soft-cooked egg. The name comes from the way they were originally made—by gently cooking eggs in the warm waters of Japanese hot springs (onsen). The result is a silky egg with a custard-like white and a creamy yolk, perfect for topping noodles, rice bowls, or even enjoyed on its own with a splash of soy sauce.
How to Make Onsen Eggs at Home
You don’t need a hot spring to make these at home! All you need is water and a pot. Here’s the easy method I use:
Boil 3 parts water in a pot.
Once it reaches a boil, turn off the heat and add 1 part cold water to bring the temperature down.
Gently place your eggs into the pot, cover with a lid, and let them sit for 10 minutes.
Carefully transfer the eggs into cold water before peeling or cracking into a bowl.
And that’s it! You’ll have the perfect onsen egg with soft whites and a jammy, runny yolk.

Tips for the Best Beef Udon Recipe
Use thinly sliced beef:
Hotpot beef cooks almost instantly and stays tender in broth. They are also very convenient to store in the freezer for quick meals like this. I always have frozen hot pot beef slices so I can quickly make a delicious meal like this when I forgot to buy groceries.
Do not overcook the beef:
Hot pot beef slices are quite forgiving in its cook time thanks to its fat content, but cooking for long hours can still break it into very small bits and pieces. Prep all ingredients ahead of time!
Taste the broth before serving:
Adjust with a splash of soy sauce or a pinch of sugar if needed.
Best Udon Noodles to Use
For the best beef udon noodles, frozen udon noodles are the way to go. They have a thick, chewy texture that closely mimics fresh udon and hold up well in stir-fries.
Frozen udon: Chewy, springy, and ideal for this recipe and my personal favorite
Dried, packaged udon: Works in a pinch, but slightly softer
Fresh udon: Great if available, though harder to find
Frozen udon noodles are widely available at Asian grocery stores and many larger supermarkets.
Ingredient substitutions and variations
Protein swap:
- Thinly sliced pork or chicken works just as well. Especially with rice! Check out my Japanese Pork Rice Bowl recipe
Vegetarian option:
- Skip the beef and use mushrooms like shiitake or enoki for depth. And of course, firm tofu is always a great option.
Broth shortcut:
- Store bought dashi can be used for an even faster version, though using dashi powder is always very convenient and easy for a weeknight
Extra toppings:
- Green onions are a must but also consider bonito flakes and an onsen egg like I did!
Storage & Reheating
- Store leftovers in an airtight container in the fridge for up to 3 days
- Reheat gently in a pan or microwave with a splash of water
- Udon noodles are best enjoyed fresh, but leftovers still reheat well
- Freezing is not recommended, as the texture of the udon can change.
