French Onion Soup Butter (Compound Butter)

Heat olive oil in a skillet over medium-low heat. Add the sliced onions and cook slowly, stirring occasionally, until they are deeply caramelized and golden brown. This will take about 25-30 minutes. Be patient and don't rush the process.

Remove the caramelized onions from the heat and let them cool slightly.

In a medium bowl, combine the softened butter, cooled caramelized onions, chopped fresh thyme, salt, and pepper.

Use a fork or spatula to thoroughly blend all the ingredients together until evenly distributed.

Transfer the compound butter to a small serving dish or shape it into a log using plastic wrap. Refrigerate for at least 30 minutes to allow the flavors to meld and the butter to firm up slightly before serving.

Serve with crusty bread, grilled steak, or your favorite accompaniments.
