Methods of forming energetic compositions include forming a premix comprising a nitrate ester, a polymer, and a stabilizer, and combining solids with the premix. Additional stabilizer may be added with the solids and may remain in a crystalline state. Some methods include dissolving a stabilizer in at least one of a plurality of nitrate esters. Energetic compositions include a continuous matrix and a stabilizer. The continuous matrix includes a nitrate ester and surrounds a solid energetic material. Some compositions include a first nitrate ester, a second nitrate ester having a decomposition rate lower than the first nitrate ester, and a stabilizer. An article includes a housing and an energetic composition in the housing.
