You would not ordinarily capitalize any letter of hors d'oeuvres. But for a menu heading (which is not required to be grammatical), either the capital H alone, or capital H and O, could be proper.
Hors d'oeuvres is the US plural, and hors d'oeuvre the singular.
The way to remember that is:
1. Both parts have an "s" at the end if it is plural. If it is not plural, only the "hors" has an "s" at the end.
2. There's an apostrophe after the first letter in the second word
3. The second word starts out as "DOE", then you add the "UV" and the rest is "RES."
No caps needed. It's a common noun. Of course, you'd capitalize the H if it was the first word in a sentence.
one hors-d'oeuvre per guest is enough.
In English, hors d'oeuvres is the plural and the singular is hors d'oeuvre.un hors-d'oeuvre, pl. des "hors-d'oeuvre". The word is invariable in French; only the determiner is changed to plural.In multiple part words, verbs, adverbs and prepositions do not change. Nouns can take the plural mark, or not depending of the sense of the word. EX: "une pomme de terre, des pommes de terre" because one or many potatoes always come from the ground.a number of examples in the short linked article (in French)
The correct English spelling of the appetizers is hors d'oeuvres.(from the French "apart from the work")

Proper capitalization is an important part of English grammar. Many websites offer information about the rules of grammar, such as Webgrammar, GrammarBook, and Grammarly. Any decent grammar textbook should also have information about capitalization.
The French (singular and plural) is hors d'œuvre; in English, the œ ligature is usually replaced by the digraph "oe" with the plural often written as "hors d'oeuvres".
you use capitalization at the beginning of sentences, the letter I, proper nouns, titles, and names.
The proper pronunciation is "or-derv" for the singular, and "or-dervz" for the plural. The spelling is "hors d'oeuvre" for both singular and plural. Its definition is, "A small snack or appetizer served before a meal".
