Dolma d'oignon is a beloved Iranian appetizer that traces back to centuries-old Persian culinary traditions of stuffing vegetables. It reflects the Iranian love for aromatic herbs, spices, and the art of slow cooking, often served during family gatherings. The dish showcases the resourceful use of onion leaves, a staple in Iranian home cooking.

In northern Iran, Dolma d'oignon may include fresh herbs like dill and mint, while in the south, cooks often add a touch of turmeric and use longer cooking times for deeper flavor. Some regions substitute rice with barley or add pomegranate molasses for a sweet‑sour note. These variations reflect local ingredient availability and regional taste preferences.

Traditionally, Dolma d'oignon is plated on a large serving platter, drizzled with a warm tomato‑lemon sauce, and garnished with fresh parsley or cilantro. It is often accompanied by flatbread, yogurt, or a simple salad of cucumber and radish. During celebrations, the dish is presented as part of a mezze spread alongside other stuffed vegetable dishes.

Dolma d'oignon is commonly prepared for Nowruz (Persian New Year), wedding feasts, and religious holidays such as Ramadan evenings. Its comforting flavors make it a favorite for family reunions and informal dinner parties. The dish symbolizes hospitality and the sharing of home‑cooked meals.

Dolma d'oignon embodies the Iranian tradition of "dolma"—stuffed vegetables—highlighting the balance of meat, rice, and herbs that defines Persian main courses. It complements other staple dishes like khoresh (stew) and kebab, offering a lighter, vegetable‑focused option. The use of aromatic spices such as cinnamon and cumin links it to the flavor profile of Iranian comfort food.

Authentic Dolma d'oignon uses medium to large onion leaves, ground lamb or beef, short‑grain white rice, fresh tomatoes, and Persian spices like turmeric, cinnamon, and dried mint. Acceptable substitutes include using ground turkey for a leaner protein, basmati rice for a fluffier texture, or adding a pinch of smoked paprika for a subtle smoky flavor without straying far from tradition.

Common mistakes include overfilling the onion leaves, which can cause them to tear, and under‑seasoning the rice‑meat mixture, leading to bland dolmas. Another pitfall is baking at too high a temperature, which dries out the onions. Aim for a gentle oven heat and a balanced filling for tender, flavorful results.

Onion leaves provide a milder, sweeter flavor that complements the rich meat‑rice filling, whereas grape leaves can be more tannic and assertive. In Iranian cuisine, onion leaves are traditionally used for their tender texture and subtle aroma, allowing the spices and tomato‑lemon sauce to shine. This choice also reflects regional availability in Iran.

Dolma d'oignon is done when the onion leaves are tender and the rice filling is fully cooked, typically about 35‑45 minutes at 180 °C (350 °F). The tomato‑lemon sauce should be bubbling around the edges, and a fork inserted into a dolma should meet little resistance. Let the dish rest for five minutes before serving to allow flavors to meld.
