When it comes to leafy greens, mizuna is an underappreciated superstar. With its delicate, frilly leaves and peppery flavor, mizuna brings both flavor and nutrition to your table. Popular in Japanese cuisine, this versatile green has recently been gaining attention in the United States due to its health benefits, culinary versatility, and easy cultivation.
In this article, we’ll explore everything you need to know about mizuna—from its nutritional profile and health benefits to cooking tips and gardening guidance—so you can make it a staple in your American kitchen.
What Is Mizuna?
Mizuna (Brassica rapa var. nipposinica) is a type of Japanese mustard green with slender, serrated leaves and a mildly spicy, peppery taste. Sometimes called Japanese mustard greens, mizuna belongs to the same family as arugula, kale, and bok choy.
Mizuna comes in several varieties:
- Green Mizuna: Traditional bright green leaves with a mild peppery flavor.
- Red Mizuna: Deep burgundy leaves with a slightly stronger spice.
- Curly Mizuna: Frilly leaves that add texture and visual appeal to salads and garnishes.
Its tender leaves cook quickly, making it perfect for stir-fries, soups, and salads, while retaining a slightly crisp texture when raw.
Nutritional Profile: Why Mizuna Is a Supergreen
Mizuna is a low-calorie green that packs a powerful nutritional punch. One cup (40 grams) of raw mizuna provides:
- Vitamin K: 45% of the daily value (DV)
- Vitamin A: 35% of DV
- Vitamin C: 25% of DV
- Folate: 10% of DV
- Calcium: 4% of DV
- Iron: 3% of DV
Mizuna also contains antioxidants, phytonutrients, and fiber, which help support heart health, bone strength, immune function, and digestion. With such a nutrient profile, it’s no wonder mizuna is considered a supergreen.
Health Benefits of Mizuna
1. Supports Heart Health
Rich in antioxidants and potassium, mizuna helps maintain healthy blood pressure and reduce inflammation, supporting cardiovascular wellness.
2. Strengthens Bones
Mizuna’s high vitamin K and calcium content contribute to strong bones and may reduce the risk of osteoporosis, a concern for many Americans.
3. Boosts Immunity
Loaded with vitamin C and other phytonutrients, mizuna strengthens the immune system, helping the body fight off infections and seasonal illnesses.
4. Promotes Eye Health
The carotenoids in mizuna, such as beta-carotene and lutein, protect against age-related macular degeneration and support healthy vision.
5. Aids Digestion and Weight Management
Low in calories but high in fiber, mizuna promotes satiety and digestive health, making it an excellent choice for weight-conscious diets.
6. Anti-inflammatory and Detoxifying Properties
Like other cruciferous vegetables, mizuna contains glucosinolates, which may help reduce inflammation, support liver detoxification, and promote long-term wellness.
How to Cook Mizuna
Mizuna’s tender leaves and peppery flavor make it a versatile ingredient for American kitchens:
- Salads: Use raw mizuna as a base for mixed greens or add it to your favorite salads for a mild spicy kick.
- Stir-Fries: Toss mizuna into stir-fries with garlic, ginger, and soy sauce for a quick and nutritious side dish.
- Soups & Stews: Mizuna wilts beautifully in broths, adding both flavor and nutrition.
- Pasta & Grain Bowls: Mix into cooked grains or pasta just before serving for extra texture and color.
- Smoothies: A handful of mizuna can be added to green smoothies for a nutrient boost without overwhelming flavor.
Pro Tip: Add mizuna near the end of cooking to preserve its nutrients and delicate texture.
Growing Mizuna at Home
Mizuna is remarkably easy to grow, even for beginner gardeners or urban farmers. Here’s how:
1. Soil and Sun Requirements
Mizuna thrives in well-draining, fertile soil with a pH of 6.0–7.5. It grows best in full sun to partial shade, especially in warmer climates.

4. Container Gardening
Mizuna grows well in pots, making it perfect for balcony gardens, kitchen windowsills, or small patios. A container 8–12 inches deep works well for most varieties.
Tips for Buying and Storing Mizuna
- Choose fresh, dark green leaves with no yellowing or wilting.
