Green onions, also known as scallions or spring onions, are a prevalent ingredient in Mexican cuisine due to their mild yet distinct onion flavor and versatility in various dishes.
They’re distinguished by their long, slender, green stalks and small, white bulbs. These onions impart a mild onion flavor that is less pungent than mature onions, making them ideal for raw applications or for adding a subtle onion taste to cooked dishes without overpowering other flavors.
What Are Green Onions?
- Botanical Classification: Green onions belong to the Allium genus, similar to other red onions, white onions, leeks, and garlic. They are Allium fistulosum, characterized by their long, thin stalks and small, underdeveloped bulbs.
- Taste, Texture, and Appearance: They have a mild onion taste, with the green part being more delicate and less intense than the white part. Their texture is crunchy, and they’re visually identifiable by their long, slender green stalks and small white bulbs.
- Parts Used in Mexican Dishes: In Mexican cooking, both the green tops and white bulbs of green onions are utilized. The green tops are often used as a garnish, adding color and freshness to dishes, while the white bulbs are commonly chopped and used in various recipes.
Green onions are an essential ingredient in many Mexican dishes, providing a mild onion flavor that complements the flavors of various spices and herbs used in Mexican cuisine.
They are used in salsas, guacamole, soups, tacos, and garnishes, contributing a subtle onion essence without overpowering the dish’s overall taste.
Flavor Profile and Pairings:
Green onions have a mild, slightly sweet onion flavor with a subtle peppery undertone. They contribute a fresh, crisp texture and a vibrant green color to Mexican dishes. When used raw, they add a refreshing bite and a bright contrast to the overall flavors.
In Mexican cuisine, green onions complement various ingredients, enhancing the taste and visual appeal of dishes. They pair well with:
- Tomatoes: Combining green onions with tomatoes in salsas or pico de gallo creates a balanced flavor profile.
- Avocado: They add a complementary mild onion flavor to guacamole or avocado-based salsas.
- Cilantro: Green onions and cilantro often work together, offering a fresh, herbal undertone to many Mexican dishes.
- Citrus: The mildness of green onions pairs nicely with the tanginess of lime or lemon juice, commonly used in Mexican cuisine.

Cooking and Preparation Tips:
- Selection and Storage: Choose green onions with firm, vibrant green stalks and store them in the refrigerator. Keep them dry and loosely wrapped in a paper towel or plastic bag to retain freshness.
- Preparing Green Onions: Rinse them thoroughly under cold water, trim off the root end, and remove any wilted parts. Use both the white bulb and the green tops for various recipes.
- Slicing and Chopping: To slice, use a sharp knife and cut crosswise, creating thin rings. For chopping, angle the knife and cut diagonally, resulting in small pieces.
- Cooking Methods: Green onions are versatile and can be used raw or cooked. When cooked, they add a milder onion flavor and can be sautéed, grilled, or added into soups and stews toward the end of cooking to retain their freshness and color.
