Ingredients You’ll Need
- 1 cup (2 sticks) unsalted butter, softened

- ½ teaspoon garlic powder

How to Make French Onion Compound Butter
Step 1: Caramelize the Onions
Heat the olive oil in a skillet over medium-low heat. Add the chopped onion and cook slowly, stirring often, for 25–30 minutes until the onions are soft, golden, and deeply caramelized.
Step 2: Let Them Cool
Remove the onions from the heat and allow them to cool completely. This step ensures the butter won’t melt when mixed.
Step 3: Combine the Ingredients
In a medium bowl, combine the softened butter, cooled onions, Worcestershire sauce, garlic powder, salt, pepper, and herbs if using. Mix thoroughly until everything is evenly incorporated.
Step 4: Shape and Chill
Transfer the mixture to a sheet of parchment paper or plastic wrap. Shape it into a log, twist the ends, and refrigerate for at least 1 hour until firm.
Step 5: Slice and Serve
Once the butter is set, slice into rounds and use as needed. It melts beautifully on grilled meats, adds flavor to roasted vegetables, or turns simple toast into something special.
Why This Recipe Works
The magic here is in the caramelized onions. Their sweetness and complexity combine perfectly with the richness of the butter. Worcestershire sauce brings umami depth, garlic adds a warm kick, and herbs give it a fresh, earthy finish. It’s a restaurant-level condiment you can make in your own kitchen with just a few simple ingredients.
