The sentence "I will begin writing my essay once I have made an outline." includes a dependent clause.

The sentence that includes a dependent clause is: "I will begin writing my essay once I have made an outline."

To identify a dependent clause, we need to look for a group of words that cannot stand alone as a complete sentence because it relies on the rest of the sentence for meaning. In this case, "once I have made an outline" is a dependent clause because it does not express a complete thought on its own. It depends on the main clause "I will begin writing my essay" to make a complete sentence.
