Cut the butter into small cubes to ensure even melting.
Place it in the saucepan and melt butter over medium-low heat.
As the butter melts, it will start to bubble and foam. Keep a close eye on it, swirling the pan occasionally to ensure even cooking.
After a few minutes, the butter will begin to change from yellow to a golden brown color. You'll notice brown specks forming at the bottom of your pan and a nutty aroma filling the air (the best part). Stir the brown specks with a wooden spoon to prevent them from burning.
Once the butter reaches a rich, caramel-like hue, remove it from the heat immediately. Be careful not to let it burn; brown butter can quickly turn from perfect to burnt butter if left unattended.
Pour the brown butter into a heat-proof bowl and use as recipe directs.
