Um, with the utmost respect...the word is sauté. If it must be Englishified then sautéd would be it.

When you have a combination of E's (as when you are according a verb to a feminine noun), the accent goes on the first E. Exceptions are extremely rare. The only way you can have an accent on second E is if the first accented E is an intergral part of the word and not a tool for accordance. Eg. the word créer (to create). If you say "he created" it would be "il a créé." That word is also one of the rarest when you conjugate to feminine because you have three Es in a row "elle a créée."
