Vegetables that Start with O with Pictures
Oca
Oca is a small edible tuber that comes from the Andes of South America. Farmers grow it for its colorful underground tubers, which may appear yellow, orange, pink, or red. Oca has a crisp texture when raw and turns soft after cooking. It tastes mildly tangy, although sunlight can make the flavor sweeter. People often boil, roast, bake, or add oca to stews.
Oakleaf Lettuce
Oakleaf lettuce is a loose-leaf lettuce variety with tender, deeply lobed leaves that resemble oak leaves. Depending on the variety, the leaves may look green, red, or reddish-brown. They have a mild, slightly sweet flavor and a delicate texture. Oakleaf lettuce works especially well in fresh salads. You can also add the leaves to sandwiches, wraps, and other light vegetable dishes.
Okahijiki
Okahijiki is a Japanese leafy vegetable whose name means “land seaweed” because its slender leaves resemble seaweed. The plant produces crisp, succulent green shoots with a mild, slightly salty flavor. Cooks usually harvest the young leaves and stems while they remain tender. First, they often blanch the shoots briefly. Then, they serve them with dressings or add them to salads and vegetable dishes.
Okinawan Spinach
Okinawan spinach is a leafy vegetable that grows well in warm, tropical climates. Its leaves have green upper surfaces and often show purple coloring underneath. Young leaves taste mild, while mature foliage develops a slightly bitter flavor. You can eat the tender leaves raw in salads. However, cooks often sauté, stir-fry, or add the greens to soups when they want a softer texture.
Okinawan Sweet Potato
Okinawan sweet potato is a purple-fleshed root vegetable associated with Okinawa, Japan. Its outer skin usually appears tan or reddish-brown, while the inside develops a deep purple color after cooking. The dense flesh tastes naturally sweet and has a starchy texture. You can steam, boil, bake, or mash these potatoes. They also add color and sweetness to breads, cakes, and desserts.
Okra
Okra is a warm-season vegetable that produces long, green pods filled with small edible seeds. Young pods have a tender texture, while older pods can become fibrous. When you cut okra, its interior releases a naturally thick substance that helps thicken soups and stews. Meanwhile, frying, roasting, grilling, pickling, and sautéing give the pods different textures and flavors.
Olluco
Olluco is a colorful Andean tuber that grows underground and serves as a traditional food in parts of South America. Its small tubers may have yellow, orange, pink, red, or green skin. Olluco has moist, firm flesh with a mild, earthy flavor and slight crispness. People often slice or boil it before adding it to soups, stews, and other traditional vegetable dishes.
Olive
Olive is the small fruit of the olive tree, although cooks often group it with vegetables because of its savory culinary role. Fresh olives taste intensely bitter, so producers cure them before people eat them. Green and black olives mainly differ in ripeness and processing. After curing, they develop salty, rich flavors that work well in salads, pizzas, breads, sauces, and Mediterranean dishes.
Onion
Onion is a bulb vegetable from the Allium family, which also includes garlic, shallots, and leeks. Its underground bulb develops several papery layers and comes in varieties with white, yellow, red, or other colored skins. Raw onions taste sharp and pungent, but heat softens their texture and brings out sweetness. Cooks sauté, roast, grill, caramelize, pickle, or serve onions fresh.
Orach
Orach is a leafy vegetable related to spinach and valued for its edible foliage. Its leaves can appear green, red, purple, or multicolored, depending on the variety. Young leaves have a mild, slightly salty flavor and work well in fresh salads. As the leaves mature, cooks usually sauté or boil them. Orach also adds a spinach-like texture to soups and vegetable dishes.
Oyster Plant
Oyster plant is a root vegetable commonly known as salsify. It produces a long, slender edible root with pale flesh beneath a darker outer skin. After cooking, the root develops a mild flavor that many people compare with artichoke. You should peel the root before preparation. Then, you can boil, steam, roast, fry, or add it to soups and hearty stews.
Ostrich Fern Fiddleheads
Ostrich fern fiddleheads are the tightly curled young shoots of the ostrich fern. People harvest them in spring before the fern leaves fully open. These tender shoots have a firm texture and an earthy, grassy flavor. However, proper identification and thorough cooking matter because not every fern produces edible fiddleheads. Cooks commonly boil, steam, sauté, or add prepared fiddleheads to soups and vegetable dishes.
