5 Healthy Korean Foods Worth Buying at Oseyo London

5 Healthy Korean Foods Worth Buying at Oseyo London

Discover 5 healthy Korean foods worth buying at Oseyo London, from kimchi and miyeok to perilla powder, roasted barley and Korean multigrains.

Key Takeaways

  • Shop beyond the basics: Oseyo is most useful when you choose Korean ingredients that are harder to replace with everyday UK supermarket products.
  • Build variety: Kimchi, miyeok, perilla powder, roasted barley and Korean multigrains each bring something different to your kitchen—from fermented vegetables to seaweed, seeds and grains.
  • Use them every week: These are not novelty ingredients. Each can fit into simple soups, rice bowls, breakfasts and drinks using familiar UK produce.

What Is Actually Worth Putting in Your Oseyo Basket?

Walk into an Oseyo store in London and it is easy to get distracted.

There are brightly coloured instant noodles, Korean sweets, bottled drinks, sauces and snacks covering almost every aisle. They are fun to explore, but if your goal is to build a health-focused Korean kitchen, the most interesting purchases are often the quieter ingredients sitting between them.

And that raises a useful question:

What should you buy at Oseyo that you cannot easily replace during your normal Tesco or Sainsbury’s shop?

Tofu is nutritious and incredibly useful—but good tofu is now widely available in British supermarkets. The same applies to brown rice and increasingly to buckwheat noodles.

For this guide, I have therefore chosen five ingredients with a stronger Korean identity and a practical reason to make the trip to a Korean grocery store.

The shortlist is kimchi, miyeok, perilla powder, roasted barley and Korean multigrain mix.

Together, they can help you add more vegetables, whole grains, seeds and traditional Korean flavours to everyday meals without turning your kitchen into a specialist pantry.

K-Well’s Shopping Rule: Use Oseyo for the ingredients that make Korean cooking distinctly Korean. Buy everyday vegetables, eggs and other basics during your normal supermarket shop.

1. Kimchi (김치): The Fermented Vegetable Staple

If you are buying only one refrigerated Korean food at Oseyo, start with kimchi.

Kimchi is made by fermenting vegetables—most commonly napa cabbage—with ingredients such as chilli flakes, garlic, ginger and spring onion. Depending on the recipe, it may also contain fish sauce or salted seafood.

Its biggest practical advantage is versatility.

Open one tub and you immediately have a flavourful vegetable side dish for rice, eggs, tofu or grilled protein. As the kimchi becomes more sour with continued fermentation, it becomes particularly useful for kimchi jjigae, kimchi fried rice and kimchi jeon.

That means very little needs to go to waste.

Why It Earns a Place in Your Basket

Kimchi brings fermented vegetables into a meal in a form that is deeply rooted in Korean food culture.

Research into fermented foods and the gut microbiome is developing, but you do not need to turn kimchi into a probiotic supplement to appreciate it. Its everyday value is simpler: it provides vegetables, strong flavour and an easy way to make a basic rice bowl feel complete.

What to Check on the Label

Compare:

  • sodium per serving
  • added sugar
  • serving size
  • whether the product is vegan or contains fish ingredients
  • storage instructions

If you want live microorganisms to be part of your purchasing decision, also check whether the product has been heat-treated or pasteurised after fermentation.

Easy K-Wellness Meal

Try: multigrain rice + tofu + cucumber + kimchi + sesame seeds

It is one of the easiest ways to turn a few supermarket ingredients into a Korean-inspired lunch.

K-Well’s Tip: Don’t discard pleasantly sour, properly stored kimchi simply because its flavour has intensified. In Korean cooking, well-fermented kimchi tastes especially better for cooked dishes such as jjigae and fried rice.

2. Miyeok (미역): The Korean Sea Vegetable for More Than Birthday Soup

British shoppers are increasingly familiar with crispy seaweed snacks, but miyeok is different.

Miyeok is dried seaweed traditionally rehydrated and used in miyeok-guk, Korean seaweed soup. It expands considerably when soaked, so a seemingly small packet can produce many servings.

In Korea, miyeok-guk has a particularly meaningful cultural connection with birthdays and postpartum food traditions. But there is no reason to save miyeok for a special occasion.

Why It Earns a Place in Your Basket

Seaweed provides minerals including iodine, although the amount can vary substantially between species and products.

Iodine is needed for normal thyroid hormone production, but this is a case where more is not necessarily better. Seaweed can be a concentrated source, so it makes sense to enjoy it as part of a varied diet rather than assuming larger quantities provide greater benefit.

From a cooking perspective, miyeok is especially valuable because dried seaweed stores well and gives soups an unmistakably Korean character.

Three Easy Ways to Use It

Miyeok-guk: Simmer rehydrated miyeok with garlic and your preferred protein or stock.

Miyeok cucumber salad: Combine rehydrated seaweed with cucumber and a light vinegar dressing for a refreshing side dish.

Miyeok rice bowl: Add a small handful of seasoned, rehydrated miyeok to multigrain rice with tofu, cucumber and sesame seeds for an easy Korean-inspired lunch.

K-Well’s Tip: Remember how dramatically dried miyeok expands. Start with much less than you think you need, soak it first, then judge the portion.

3. Perilla Powder (들깨가루): The Nutty Korean Ingredient Your Soup Is Missing

This is probably the most interesting ingredient on the list for a British home cook.

Deulkkae-garu (들깨가루), or ground perilla seed, has a rich, earthy and nutty flavour. Korean cooks use it to add both flavour and body to soups, stews and vegetable dishes. Unlike sesame seeds, perilla is still relatively unfamiliar in mainstream UK cooking. That makes it exactly the kind of ingredient worth looking for during an Oseyo trip.

Why It Earns a Place in Your Basket

Perilla seeds contain unsaturated fats and are notable for their alpha-linolenic acid (ALA) content, a plant-based omega-3 fatty acid. Reviews of perilla seed composition identify ALA as a major component of perilla seed oil.

But its culinary advantage may be even more useful.

Ground perilla can make a broth taste richer and slightly creamier without needing actual cream. It works beautifully with mushrooms, tofu and leafy vegetables.

How to Use Perilla Powder

Start with one tablespoon near the end of cooking and adjust according to taste.

Try it in:

  • mushroom soup
  • miyeok-guk
  • tofu stew
  • vegetable soup
  • Korean-style mushroom hotpot
  • seasoned vegetable dishes

You can even use a small spoonful in a simple mushroom and leek soup made entirely with ingredients from your local UK supermarket.

K-Well’s UK Hack: Simmer mushrooms, leek and garlic in stock, then stir in a spoonful of perilla powder toward the end. It gives an ordinary vegetable soup a distinctly Korean, nutty finish without relying on cream.

Because ground seeds contain natural oils, follow the package storage instructions and keep the product tightly sealed after opening.

4. Roasted Barley (볶은 보리): Make Your Own Bori-cha

A bag of roasted barley may not look as exciting as a Korean snack haul, but it can become one of the most frequently used items in your kitchen.

Koreans use roasted barley to prepare Bori-cha (보리차), roasted barley tea.

The grains are simmered or steeped in water, producing a light brown drink with a toasted, almost nutty cereal aroma. It can be enjoyed hot in winter or chilled in the refrigerator during warmer months.

Why It Earns a Place in Your Basket

Traditional Bori-cha made from barley and water is naturally caffeine-free and unsweetened.

Its main wellness advantage is therefore wonderfully uncomplicated: it gives water flavour without requiring sugar or caffeine.

For anyone who finds plain water boring, keeping a jug of chilled Bori-cha in the refrigerator can make everyday fluid intake more enjoyable.

How to Make It

For a simple home version:

  1. Add roasted barley to a saucepan of water, following the package directions.
  2. Bring to a boil and simmer until the water develops a light toasted colour and aroma.
  3. Strain the barley and enjoy warm, or cool and refrigerate for later.

For an even easier kettle method: If your kettle is suitable for brewing grains or tea directly, add the roasted barley to the water and boil them together. Let it steep briefly for a deeper toasted flavour, then strain and enjoy warm or chilled. Always check your kettle manufacturer’s instructions first.

The strength is easy to adjust—simply use less barley or shorten the brewing time for a lighter, more delicate flavour.

K-Well’s Tip: If you regularly drink Bori-cha, loose roasted barley is a particularly simple option because it avoids the need for a tea bag altogether.

Barley contains gluten, so Bori-cha made from barley is not suitable for people who need to follow a gluten-free diet.

5. Korean Multigrain Mix (Japgok): An Easy Way to Add Grain Variety

Look for Japgok (잡곡), Korean multigrain mixes in the grain section. Depending on the blend, one packet may combine ingredients such as black rice, barley, millet, sorghum and beans.

Why It Earns a Place in Your Basket

The biggest advantage is convenience and variety. Instead of buying several bags of individual grains and legumes, a Korean Japgok mix lets you experiment with different colours, flavours and textures in your everyday rice.

Start by mixing a small amount with your usual rice and adjust the ratio as you become familiar with the texture. Always check the packet instructions, as blends containing larger beans or grains may benefit from soaking.

K-Well’s Tip: Don’t choose a mix simply because the packet says “15 grains” or “20 grains.” Check the ingredient list and choose a combination of grains and beans you will genuinely enjoy eating regularly.

The Smart Oseyo + UK Supermarket Strategy

A healthy Korean kitchen in Britain does not require buying everything from a Korean supermarket.

In fact, the smartest approach is to split your shopping.

Buy at Oseyo

Look for the ingredients that provide Korean culinary identity:

Kimchi • Miyeok • Perilla Powder • Roasted Barley • Japgok

Buy at Your Regular UK Supermarket

Pick up the everyday supporting ingredients:

cabbage • mushrooms • cucumber • spring onions • garlic • eggs • tofu • fresh fruit and vegetables

This is usually more practical than treating every Korean recipe as a specialist shopping expedition.

It also gives you much more flexibility. A punnet of British mushrooms can become a perilla mushroom soup. A supermarket cucumber can become miyeok muchim. Eggs and leftover multigrain rice can become a quick breakfast bowl with kimchi.

The Korean ingredients provide the flavour framework; familiar local produce does the rest.

How I Would Spend £20 at Oseyo

If this is your first visit and you don’t want to buy five unfamiliar foods at once, prioritise ingredients according to how often you will actually use them.

Start with kimchi for immediate meals.

Next, choose Japgok if rice is already part of your weekly diet.

Add miyeok if you enjoy soups.

Then experiment with perilla powder when you want to explore a flavour that is much harder to reproduce with standard British pantry ingredients.

Finally, pick up roasted barley if you enjoy caffeine-free drinks or want to make Bori-cha at home.

The goal isn’t to leave with the biggest Korean grocery haul. It is to leave with ingredients you will actually finish.

FAQ

Q1. What is the healthiest food to buy at Oseyo?

There is no single “healthiest” Korean food. A better approach is to choose foods that add something useful to your overall diet. Kimchi contributes fermented vegetables, miyeok provides a sea vegetable, perilla brings seeds and unsaturated fats, and multigrain blends can increase whole-grain variety.

Q2. Is Korean multigrain rice healthier than white rice?

It depends on the mixture and your overall meal, but blends containing intact whole grains and legumes can provide more fibre and nutritional variety than refined white rice alone. Harvard and NHS dietary guidance both encourage choosing whole-grain and higher-fibre carbohydrate sources as part of a balanced diet.

Q3. Do I need to shop at a Korean supermarket to eat healthy Korean food?

No. Use Korean supermarkets strategically for harder-to-find ingredients and buy fresh vegetables, tofu, eggs and other everyday foods wherever they are convenient. This Korean pantry + UK produce approach is often the easiest way to cook Korean-inspired meals regularly.

K-Well’s Final Thoughts

The best Oseyo haul isn’t necessarily the one filling your basket with the most Korean products.

It is the one that changes what you can cook when you get home.

Kimchi gives an ordinary rice bowl instant fermented depth. Miyeok opens the door to Korean soups and seaweed salads. Perilla powder transforms mushrooms and vegetables with a flavour rarely found in a mainstream British pantry. Roasted barley creates a simple caffeine-free drink, while Japgok makes an everyday bowl of rice more varied in texture and grains.

More importantly, all five work alongside ingredients you can pick up during an ordinary UK supermarket shop.

That is the K-Wellness Kitchen approach: keep the Korean ingredients authentic, keep the everyday cooking practical, and build variety across the whole meal rather than searching for one miracle food.
