How to Make It
Combine pears and brown sugar in a large bowl; toss to lightly coat.
Melt butter in a skillet over medium; add thyme sprigs. Cook, swirling pan or stirring constantly, until butter browns, about 1 minute. Remove thyme sprigs; discard.
Add coated pear slices to browned butter, and cook, stirring occasionally, until softened and slightly caramelized, about 20 minutes. Squeeze with lemon, if desired; sprinkle with fresh thyme leaves. Serve alone, or over roasted pork, Brie cheese, or vanilla ice cream.
