15 Mins Korean-Inspired Beef and Seaweed Soup

In Korea, birthdays are often celebrated with a comforting bowl of beef and seaweed soup — called Miyeok-guk (미역국). It’s not just food — it’s a bowl of love and blessings, symbolising good health, long life, and gratitude.
As a Chinese, I also grew up eating seaweed and beef soup, though the version I’m most familiar with usually features pork. If you want truly excellent flavour, you’d normally cook it in a clay pot over fire, letting it simmer for hours — rich, deep, and irreplaceable, but definitely time-consuming.
The traditional Korean way often involves simmering raw beef and seaweed for a long time as well, developing layers of umami flavour slowly. It’s delicious — but also time-consuming. And on a busy day, when you just want something nourishing and satisfying now, that’s not ideal.
I was experimenting one day, wondering if there was a faster way to make this soup without cooking my own beef from scratch. Then I came up with this lazy Korean-inspired version.
The secret lies in two magical shortcuts:
- Ready-to-eat roast beef – gives instant richness, just like beef that’s been simmered for hours.
- Dasida beef-flavoured soup stock – a beloved Korean seasoning made from real beef extract and aromatics. It instantly deepens the broth with that savoury, slow-cooked taste. You can get it from local Asian supermarkets.
With these two, you can make a flavourful, nourishing bowl of beef and seaweed soup in under 15 minutes — no fuss, no long boiling, no greasy kitchen.
It’s simple, quick, and honestly perfect for busy people who still crave a homemade taste of comfort.

Ingredients
Main Ingredients
- 2 tbsp dried wakame seaweed (dried miyeok)
- 60-80g ready-to-eat roast beef
- ¼ onion
- 2 tbsp minced garlic
- 1 tbsp chopped scallions
- 2 cups water
Seasonings:
- 1 tbsp neutral oil
- ½ tbsp Dasida beef-flavoured soup stock (adjust to taste)
Optional Add-ons:
- ½ tsp sesame oil
- A small pinch of black pepper
- 1 tsp roasted sesame seeds (for topping)
- ½ block of soft tofu or 1 soft-boiled egg

Instructions
1. Soak the seaweed
Start with 2 tablespoons of dried wakame seaweed. Place it in a bowl and cover with plenty of cold water — at least three times its volume.
Let it soak for 5 to 7 minutes, stirring once or twice to help it rehydrate evenly. The seaweed will expand dramatically — up to 6–8 times its dry size — turning glossy, slippery, and dark green.
Once it’s fully soft, drain the water, rinse it briefly under cold running water to remove any salt or residue, then gently squeeze out the excess moisture with your hands. Set aside.
❤️ Tip: If you bought salted seaweed (not the dried kind), rinse it several times until the salty taste fades, then soak for just 2–3 minutes before using.

2. Prepare the soup base
In a pot, heat 1 tbsp neutral oil over medium heat. Once it’s warm, add 2 tbsp minced garlic.
Stir-fry gently for about 20–30 seconds, until it becomes aromatic and slightly golden. Be careful not to burn it — burnt garlic turns bitter and can overpower the broth.
This simple step is the foundation of the soup’s flavour. The garlic infuses the oil and gives your broth that rich, savoury undertone that makes it taste “home-cooked” instead of flat.
If you want an extra depth of flavour, you can also toss in a few pieces of thinly sliced roast beef at this stage and stir-fry them with the garlic for 30 seconds — this caramelises the meat edges a little and builds umami right from the start.
3. Add water and onion
Pour in 2 cups of water. Then add your quarter onion (keep it in one big chunk — we’ll remove it later).
The onion slowly releases natural sweetness as it simmers, balancing the savouriness of the beef stock.
Let the water heat up until it’s just about to boil. You’ll see small bubbles forming around the edges — that’s your signal to move on.

4. Add the main ingredients
Now, add your rehydrated seaweed, ½ tablespoon of Dasida beef-flavoured soup stock, and ready-to-eat roast beef.
Gently stir to help the seasoning dissolve evenly. The broth will turn slightly cloudy — that’s a good sign! It means the seaweed and beef flavours are melding beautifully into the soup.
Turn off the heat after boiling for 1 min.
During this time, your kitchen will fill with a light, savoury aroma — warm, comforting, and a bit nostalgic. The seaweed softens fully, the beef becomes tender, and the broth turns rich and flavourful without any long simmering needed.
❤️ Lazy-day secret: Using roast beef means no pre-boiling, no scum, and no cleanup. It saves you time while keeping all that satisfying, slow-cooked flavour.
5. Adjust and finish
Once the soup has simmered, taste the broth.
If you prefer a stronger flavour, add a pinch more Dasida stock or a dash of salt.
If it’s too salty, add a splash of hot water to balance it out.
Remove the onion chunk — it’s already given its sweetness to the soup.
Finally, drizzle in ½ teaspoon of sesame oil for aroma, and sprinkle some chopped scallions on top for colour and freshness. If you like a bit of texture, finish with a few roasted sesame seeds.
Serve immediately while it’s hot. The broth should be slightly cloudy, silky, and full of flavour, with tender pieces of beef and glossy green seaweed floating through it.

Extra Tips
1. Texture Control
Simmer gently; overcooking makes the seaweed soft and slimy.
2. Onion matters
Adds natural sweetness and depth without overpowering the soup.
3. Add tofu or egg
Drop in tofu cubes or an egg for extra nutrition and comfort.or summer.
4. Serving Ideas
Best with hot steamed rice. Add kimchi or bean sprouts for a full Korean meal.
5. Storage Tip
Refrigerate up to 2 days. Reheat slowly — don’t reboil, or the seaweed may fall apart.

This lazy Korean-style beef and seaweed soup captures everything I love about homemade comfort food: it’s warm, nourishing, and made with love — but without the hours of effort.
The seaweed brings the ocean’s gentle sweetness, the beef adds depth, and the sesame oil ties it all together with a nutty aroma that lingers. Every spoonful feels soothing — like a quiet hug after a long day.
Whether you’re celebrating your birthday, missing home, or simply craving a quick, soulful bowl of soup — this version gives you all the comfort of tradition, with none of the stress.
Simple ingredients, minimal effort, maximum warmth.
