In the same skillet over medium heat, melt half of the butter. Add the chopped onion and season with 0.5 teaspoon kosher salt. Cook, stirring occasionally, until translucent, 7 to 9 minutes. Add garlic and sage, then cook, stirring, until fragrant, about 1 minute.

Add the dry orzo and remaining butter to the skillet. Cook, stirring occasionally, until the orzo is toasty and golden brown, 2 to 3 minutes.
