Melt the butter in a saucepan over medium heat. Stir occasionally to ensure even melting.
Once the butter is melted, continue cooking it over medium heat, stirring frequently, until it turns a deep golden brown color and smells nutty, about 5-7 minutes. Be careful not to burn the butter.
Add the dried sage to the browned butter and stir to combine.
Cook the sauce for an additional 1-2 minutes, stirring constantly, until the sage is fragrant.
Remove the pan from the heat and season the sauce with salt and pepper to taste.
Serve the sauce immediately over pasta, roasted vegetables, chicken, or pork. Garnish with additional chopped sage.
