Chiles rellenos: the poblano battered and bathed in tomato broth

What is it?

Chiles rellenos are one of the pillars of Mexican home cooking: poblano chillies roasted, peeled, deveined, generally stuffed with fresh cheese or meat picadillo, battered with egg white beaten to soft peaks and fried in oil, then served bathed in a light tomato broth seasoned with onion, garlic and spices. The result is a dish of contrasts: the fleshy and slightly spicy chilli inside, the melted cheese or sweet-savoury picadillo, the spongy golden batter layer, and the tomato sauce that envelops everything with its acidity and sweetness. They are generally served with Mexican rice, frijoles de la olla and maize tortillas to make tacos. They are a Sunday dish, a comida corrida favourite at fondas and a menu staple at weddings, baptisms and family celebrations throughout Mexico.

Origin and history

Chiles rellenos are an emblematic dish of Puebla cuisine and are documented from the 16th century. There are several versions of their exact origin. The most widespread places them in the convents of Puebla during the colonial period, where the nuns made use of the abundant poblano chillies of the region and stuffed them with meat, fruit or cheese, battering them with egg, a technique imported from Spanish cuisine. The sister of chef Ricardo Muñoz Zurita, in his Diccionario Enciclopédico de la Gastronomía Mexicana, cites New Spain recipe books that already include versions of egg-battered chillies from the 17th century. Their popularisation throughout Mexico occurred in the 19th and 20th centuries through recipe books such as El Cocinero Mexicano of 1831 (one of the first printed in independent Mexico) and, in the 20th century, the books of Josefina Velázquez de León, which standardised the recipe. The batter technique with egg beaten to soft peaks is of Spanish origin, inherited from Arab-Andalusian traditions that arrived in New Spain. Today chiles rellenos form part of the national culinary landscape, with regional variants in each state: with sweet-savoury picadillo, with goat's cheese, bathed in mole or pipián, dry without batter, and even cold in escabeche.

Characteristic ingredients

The poblano chilli is the base: large green chilli, fleshy, with thick walls and moderate heat, native to the Puebla Valley, today also grown in other states such as Morelos, Hidalgo and Zacatecas. It is roasted directly on the gas flame or on a comal until the skin is charred; it is placed in a closed bag to sweat for a few minutes and is peeled. A lengthwise cut is made on one side, seeds and veins are removed (which can be kept for more heat), and it is stuffed. The classic filling is fresh cheese or panela in bars, although Oaxaca cheese, ranchero cheese or picadillo are also used. The traditional picadillo combines beef or pork mince stewed with onion, tomato, almonds, raisins, olives and spices, sweet-savoury in the Puebla style, similar to the filling of chile en nogada. They are battered with egg white beaten to soft peaks, gently folding in the yolks, and lightly floured before being dipped in the egg and fried in hot oil. The broth is made with boiled tomato blended with onion and garlic, seasoned with oregano, bay leaf, cumin and sometimes chicken broth, simmered until slightly thickened and seasoned.

Cultural significance

Chiles rellenos are gastronomic heritage of Mexico and an emblem of Puebla cuisine, alongside mole, chiles en nogada and cemitas. Convent cuisine in Puebla, particularly that of the Santa Mónica, Santa Rosa and Santa Clara convents, was key in developing many iconic dishes of Mexican gastronomy, including chiles rellenos in their different variants. Traditional Mexican Cuisine, declared Intangible Cultural Heritage of Humanity by UNESCO in 2010, includes chiles rellenos as one of the representative dishes. Economically, chiles rellenos sustain the demand for fresh poblano chilli, grown by thousands of small producers in central Mexico, as well as the artisanal fresh cheese industry. They are a dish for fondas, comida corrida and the family table, present on wedding and celebration menus. Contemporary Mexican chefs such as Patricia Quintana, Margarita Carrillo Arronte and Pati Jinich have documented and reinterpreted chiles rellenos in traditional and signature versions, keeping alive a recipe almost 500 years old. The phrase 'having chile relleno on the table' is synonymous with Sunday family time for many Mexicans.

Frequently asked questions

What is the difference between chiles rellenos and chiles en nogada?

Chiles rellenos are poblano chillies battered with egg, fried and bathed in hot tomato broth. Chiles en nogada use the same poblano chilli but with a specific filling of fruit picadillo with meat, are served cold or warm, without batter, and are bathed in a cold sauce of Castilian walnut, decorated with pomegranate and parsley to represent the Mexican flag.

What do chiles rellenos taste like?

The poblano chilli brings moderate heat with vegetal and fruity notes, softened when roasted. The melted cheese or picadillo provides unctuousness and deep flavour. The egg batter adds spongy texture and a subtle French-toast-like flavour. The tomato broth gives fresh acidity, cooked sweetness and onion-and-garlic seasoning, balancing the whole.

How are chiles rellenos served?

They are served hot on a deep or flat plate, bathed with tomato broth and, optionally, sprinkled with chopped onion or coriander. They are accompanied by Mexican rice and frijoles de la olla or refried beans, with hot maize tortillas on the side to make tacos with the chilli and the broth. They are eaten with knife and fork, opening the chilli to mix it with the broth and the melted cheese.

Where do chiles rellenos come from?

They are native to the Puebla Valley, where the poblano chilli is grown and where the colonial convents of the 16th and 17th centuries developed the technique of stuffing and battering chillies with egg. The recipe is documented in El Cocinero Mexicano of 1831 and in later Puebla recipe books. Today they are national heritage with regional variants in every Mexican state.
