Disclosed is a plastic oil-and-fat composition which is prepared using an oil-and-fat having substantially no trans-acid group as the sole oil-and-fat raw material and is reduced in coarsening of an oil-and-fat crystal during storage. The plastic oil-and-fat composition is prepared using an oil-and-fat having substantially no trans-acid group as the sole oil-and-fat raw material and a glycerin fatty acid ester blended to the oil-and-fat, wherein the glycerin fatty acid ester satisfies the following requirements (1) and (2): (1) the palmitic acid content is 10% or higher and the total content of palmitic acid and stearic acid is 90% or higher relative to 100% of the fatty acids constituting the glycerin fatty acid ester, and substantially no trans-acid is contained; and (2) the content of a diester is 50% by mass or higher and the content of a monoester is 5% by mass or lower relative to 100% by mass of the glycerin fatty acid ester.
