Korean Green Onion
Korean green onions, known as daepa (대파), are one of the most fundamental ingredients in Korean cuisine. Characterized by their thick white stalks and deep, aromatic flavor, they are used as a base in countless dishes—soups, stews, marinades, and stir-fries. Unlike thin scallions, daepa adds a bold aroma and natural sweetness when grilled or simmered. It plays a starring role in dishes like pajeon (green onion pancake), samgyetang (ginseng chicken soup), and pa-kimchi (green onion kimchi). Rich in vitamin C, calcium, and allicin, Korean green onions are valued for boosting immunity, aiding digestion, and preventing colds. Both flavorful and nourishing, daepa represents the true essence of Korean home cooking.

Korean green onion, known as daepa (대파) in Korean, stands as one of the most fundamental aromatics in Korean cooking. Unlike the slender scallions common in Western cooking, Korean green onions boast thick white stalks and a robust, slightly sweet flavor that transforms dishes from ordinary to extraordinary.
What Makes Korean Green Onion Different?
Korean green onions differ significantly from their Western counterparts in both appearance and flavor profile. The most distinctive feature is their thick, substantial white stalk, which can measure up to an inch in diameter. This white portion develops a sweeter, more complex flavor when cooked, releasing a deeper aroma compared to thin scallions.
When raw, Korean green onions deliver a sharp, pungent bite with underlying sweetness. However, cooking transforms them entirely – they become mellow, almost caramelized, adding umami depth to broths and stews. According to the Korean Food Promotion Institute, this unique characteristic makes daepa irreplaceable in traditional Korean cooking (https://www.hansik.or.kr/en/).
Key Distinguishing Features:
- Thicker white stalks (2-3 times wider than regular scallions)
- Stronger aromatic compounds that withstand long cooking times
- Higher sugar content that caramelizes beautifully when grilled
- More pronounced allicin content contributing to health benefits
Why Is Korean Green Onion Essential in Korean Cuisine?
Korean green onion functions as the foundational aromatic alongside garlic and ginger in Korean cooking. It appears in virtually every category of Korean food – from basic seasoning bases to starring roles in signature dishes.
Essential Traditional Applications:
Star Ingredient in Signature Dishes
- Pajeon (파전): Green onion pancakes where whole daepa pieces are suspended in crispy batter
- Pa-kimchi (파김치): Whole Korean green onions fermented with gochugaru and fish sauce
- Samgyetang (삼계탕): Ginseng chicken soup where large daepa pieces infuse the medicinal broth
- Daepa gui (대파구이): Grilled whole green onions served as banchan with ssamjang
In Korean culinary tradition, Korean green onions represent the warmth of home cooking and comfort food. The practice of adding generous amounts of chopped daepa to soups and stews reflects Korean hospitality – creating nourishing, flavorful meals for family and guests.
What Are the Health Benefits of Korean Green Onion?
Korean green onions pack impressive nutritional value alongside their culinary versatility. The thick white stalks contain high concentrations of beneficial compounds that support overall wellness.
Rich in Allicin Korean green onions contain significant amounts of allicin, which has been studied for its antimicrobial and anti-inflammatory properties. This explains why Korean traditional medicine uses green onion preparations for cold and flu symptoms.
Key Nutrients:
- Vitamin C: Supports immune function (20% daily value per serving)
- Calcium: Supports bone health
- Vitamin K: Essential for blood clotting
- Antioxidants: Help protect cells from oxidative stress
How Do You Store Korean Green Onions Properly?
Proper storage extends the life of Korean green onions and maintains their flavor potency.
Short-Term Storage (1-2 Weeks):
Refrigerator Method Wrap unwashed Korean green onions loosely in paper towels, then place in a perforated plastic bag in the refrigerator’s crisper drawer. Replace paper towels if they become damp to prevent mold growth.
Water Storage Method Place trimmed Korean green onions upright in a jar with 1-2 inches of water, covering only the roots and white portions. Cover loosely with a plastic bag and refrigerate. Change the water every 2-3 days.
Long-Term Storage (3-6 Months):
Freezing Cut into desired sizes, spread on a baking sheet and freeze until solid, then transfer to freezer-safe containers. Frozen daepa works perfectly in cooked dishes but loses its crisp texture when thawed.
What Can You Cook With Korean Green Onion?
Korean green onion’s versatility spans the entire spectrum of Korean cooking, from essential background flavoring to showstopping main ingredients.
Core Cooking Techniques:
As Aromatic Base Finely chopped Korean green onion combined with minced garlic forms the foundation of marinades for bulgogi, galbi, and grilled meats. The white portions provide sweeter, deeper flavor while the green parts offer fresh, bright notes.
In Soups and Stews Large pieces of Korean green onion (2-3 inches) go into doenjang jjigae and kimchi jjigae. As these dishes simmer, daepa releases its flavors gradually, sweetening the broth while maintaining structural integrity.
Grilled and Roasted Whole Korean green onions, lightly oiled and grilled until charred, become a beloved banchan. The grilling caramelizes the natural sugars, creating smoky-sweet complexity.
Substitution Guidelines: When Korean green onions aren’t available:
- Leeks: Use white and light green portions for similar sweetness
- Large scallions: Bundle 2-3 regular scallions to approximate one Korean green onion
- Regular green onions: Acceptable in a pinch, but double the quantity
Where Can You Buy Authentic Korean Green Onions?
Korean and Asian Grocery Stores Korean markets stock authentic daepa year-round. Look for bundles labeled "daepa" or "Korean green onion." Quality indicators include thick white stalks, firm texture, and fresh green tops without yellowing.
Online Retailers Several online Korean grocery platforms ship fresh Korean green onions nationwide. Some suppliers offer frozen pre-chopped options, which work well for soups and stews.
Quality Selection Tips:
- Choose bundles with at least 1-inch diameter white stalks
- Fresh daepa has crisp, upright green tops
- Smell should be mildly oniony, not overly pungent

Spring Cabbage (Bomdong)
Spring cabbage, or bomdong (봄동) in Korean, is a highly anticipated seasonal vegetable that appears in Korean markets between late winter and early spring. Unlike regular napa cabbage, it grows with loose, delicate leaves and features a naturally sweet flavor and crisp texture.
For Korean home cooks, bomdong’s arrival signals the transition from winter’s heavy dishes to spring’s lighter, refreshing fare. This versatile green is prized for its ability to quickly absorb seasonings while maintaining its characteristic crunch, making it a cornerstone ingredient in Korean seasonal cooking. In particular, bomdong geotjeori (spring cabbage fresh kimchi) is one of the most beloved side dishes in Korean households during spring, as it can be prepared quickly and enjoyed immediately. Beyond geotjeori, it’s also commonly used in light soups, stir-fries, and as wraps for grilled meats.
Korean Salt
Korean salt is an essential seasoning used in nearly every part of Korean cooking—from salting napa cabbage for kimchi to adjusting the final flavor of soups like seolleongtang, galbitang, and miyeok-guk. Coarse sea salt is especially valued for its mineral-rich profile, helping vegetables maintain crisp texture during salting and creating the ideal environment for fermentation in kimchi, doenjang, and gochujang. As a foundational ingredient in Korean kitchens, salt supports flavor development, preservation, and the balance of traditional Korean dishes.
