I am trying to write a recipe in the formal command. Is this right?
La receta Precaliente el horno 350 grados. Fría tortillas hasta que ellos sean suaves. Llene con queso. Cubra con salsa. Rocíe con queso. Cocine enchiladas 20 minutos.

Precaliente el horno a (hasta) 350 grados.
Fría tortillas hasta que ellos ellas sean suaves
All of your verbs seem conjugated to the proper formal command form.
Cocine enchiladas por 20 minutos.
Suggestion: I would write the 350°F in centigrade as well unless your only making the recipe for Latinos in the U.S.
(350 -32) x 5/9=177°C
Often the infinitive is used in recipes rather than the imperative form:
Precalentar... Freír... etc.
