Sattu Paratha is a stuffed flatbread from Bihar, where a paratha is packed with sattu, the roasted gram flour that anchors much of the state's everyday eating. The angle is the filling. Sattu is nutty and dry, full of roasted-chickpea flavor, and when it goes into a flatbread it brings a savory, almost smoky depth that a plain paratha never has. This is a working food, dense and filling, built to carry someone through a long morning rather than to be delicate.
The build runs in a clear order. The sattu is loosened with mustard oil, finely chopped onion, minced green chili, and assertive seasoning, often carom seeds, garlic, and a sharp pickle masala, plus a little water so the dry flour just holds together without going pasty. A wheat-dough ball is opened, a generous spoon of the spiced sattu sealed inside, and the parcel rolled out gently so the filling spreads evenly without bursting the seam. It cooks on a hot tawa with ghee or oil until both faces are blistered and the inside is cooked through but still a touch crumbly. Good execution is obvious: the filling is evenly distributed corner to corner, well salted, fragrant with mustard oil and carom, and the bread is cooked through without a doughy core. Sloppy execution means a thick under-stuffed patch of plain dough on one side, a dry filling that pours out when you tear it, or a seam that splits and leaks the sattu onto the tawa.
It shifts with the cook's hand and the household. The amount of mustard oil and green chili is the real lever, since sattu drinks up seasoning and a timid mix tastes flat and powdery. Some keep it lean and dry; others fold in chopped pickle, ajwain, and a little pickle brine for a sharper, oilier bite. It is almost always eaten with more raw onion, green chili, and pickle on the side, and a knob of butter melting on top is common. The plain sattu drink, also a Bihar staple, is a close cousin but deserves its own article rather than being crowded in here. A sattu paratha lives or dies on the filling being moist enough to bind and bold enough to season the whole bread.
