A Comforting Bowl of Soup for Chilly Days
When you return home after a long, exhausting day, there is nothing quite like a warm, refreshing bowl of soup to comfort your soul. Instead of heavy or overly stimulating food, a clear broth that combines the natural sweetness of vegetables with the deep umami of seafood hits the spot perfectly. In Korean cuisine, 'Ojingeo Muguk' (Squid and Radish Soup) is the quintessential dish for such moments.
Many people struggle with making squid soup at home because the squid often turns rubbery, or the broth ends up cloudy and muddy. However, with this golden recipe and a few key techniques, you can easily create a refreshing, restaurant-quality squid and radish soup right in your kitchen. Let's dive into how the cooling flavor of radish, the unique aroma of squid, and a rich savory broth come together in perfect harmony.

Why Squid and Radish are a Match Made in Heaven
Squid and Korean radish (Mu) are a legendary pairing in Korean culinary history.
- Taurine-Rich Squid: Squid is packed with taurine, which is excellent for relieving fatigue. It provides a unique umami that is perfect for broths, while its chewy yet tender texture adds joy to every bite.
- Radish, the Natural Digestif: Korean radish contains diastase, a digestive enzyme that is very gentle on the stomach. As it cooks, it releases a natural sweetness that deepens and softens the broth without the need for artificial flavorings.
- Fantastic Synergy: The crispness of the radish neutralizes any overly fishy odors from the squid, while the savory essence of the squid permeates the radish. It's especially famous in Korea as the ultimate hangover cure.

Key Ingredients for the Perfect Flavor
This recipe makes a generous portion for two adults. The freshness of your ingredients will dictate the quality of your broth.
Main Ingredients
- Squid: 1 whole (fresh is highly recommended, but frozen works fine too. Ensure intestines are removed.)
- Korean Radish (Mu): About 2 handfuls (roughly 1/4 of a whole radish. It should be heavy and firm.)
- Green Onion: 1/2 stalk (essential for a refreshing aroma.)
- Korean Red Pepper Flakes (Gochugaru): 1 tbsp (adjust according to your spice preference.)
- Minced Garlic: 1/3 tbsp (don't overdo it, or the garlic will overpower the squid.)
- Sea Salt: As needed (using high-quality sea salt elevates the elegance of the broth compared to processed table salt.)
Secret Broth Ingredients
- Dried Anchovies (for broth): 5-6 pieces
- Dried Kelp (Dashima): Two 2-inch squares
- Dipori (Large Dried Anchovies/Herring): 2-3 pieces (Adding Dipori creates a much heavier, slightly sweeter, and premium broth compared to using just regular anchovies.)
- Water: About 1 liter

Step-by-Step Guide to Tender Squid & Refreshing Broth
1. The Golden Rule of Ingredient Prep
First, prep your ingredients into bite-sized pieces.
- Slicing the Radish: Peel the radish and cut it into bite-sized squares (about 1 inch wide and 1/4 inch thick). If it's too thin, it will turn to mush; if too thick, it takes too long to cook and won't absorb flavors well.
- Scoring the Squid: Wash the squid thoroughly. On the inside of the body tube, gently score the flesh in a tight, diagonal crisscross pattern. This not only looks beautiful when cooked but also helps the squid absorb flavors and ensures a much tender bite. Cut the body into bite-sized pieces and separate the tentacles.
2. Building a Robust Foundation: The Broth
Boiling seafood in plain water versus a rich stock makes a world of difference.
- Add 1 liter of water to a pot along with the dried anchovies, kelp, and dipori. Bring to a boil over high heat.
- Once it reaches a rolling boil, remove the kelp immediately. (Boiling kelp for too long releases a slimy substance that ruins the broth's texture.)
- Reduce to medium heat and simmer for another 10 minutes to extract all the savory goodness. Strain out the anchovies and dipori, leaving a clean, clear golden broth.
3. Extracting the Sweetness of the Radish
- Add the sliced radish directly into the clear broth.
- Cover and boil until the radish turns somewhat translucent. During this process, the natural, refreshing sweetness of the radish deeply infuses the soup.
4. Adding the Peak of Umami: Seasoning
- Once the radish is translucent, add 1/3 tbsp of minced garlic. The gentle garlic aroma perfectly balances the seafood scent.
- Stir in 1 tbsp of red pepper flakes. If you prefer a non-spicy, clear soup, you can skip this, but for that classic Korean kick, it is highly recommended.
5. The Golden Timing for the Squid (★CRUCIAL★)
This is where many people fail. If you add the squid at the beginning with the radish, the proteins will seize up and become incredibly tough over time.
- Wait until the radish is fully cooked and the broth is at a vigorous, rolling boil before adding the prepared squid.
- Squid cooks extremely fast. Boil it quickly over high heat just until the flesh turns opaque white and the scored patterns curl up beautifully. Turning off the heat promptly is the ultimate secret to keeping the squid wonderfully tender.
6. Elevating the Broth with Proper Salting
- Instead of soy sauce, which can darken the broth and alter its pure flavor, season your soup with high-quality sea salt (such as Hamcho salt or roasted sea salt).
- Good sea salt adds a rich mineral complexity. Taste the broth while it's piping hot; it should taste just a tiny bit saltier than you prefer, as it will balance out perfectly once you eat it with rice.
7. The Finishing Touches
- Right as the squid finishes cooking, toss in the sliced green onions to maximize that refreshing herbal note.
- While boiling, you'll notice foam and impurities rising to the surface. Gently skim this off with a spoon. This extra step guarantees a crystal-clear, clean-tasting broth.

Pro Tips for Serving
This lovingly prepared Ojingeo Muguk is best enjoyed with a bowl of freshly steamed white rice. Submerge your rice into the broth and top it with a piece of perfectly fermented Kimchi or Kkakdugi (radish kimchi). You will feel the fatigue of the day melt away instantly.
If you want an extra spicy kick, slice up a Cheongyang chili pepper (or jalapeño) right before serving. This soup also reheats wonderfully the next day; the flavors meld even further, creating an even deeper profile.
