Description

Ingredients
Onion Mixture
- 1 large sweet yellow onion, sliced
- 2 tablespoons unsalted butter, softened
- ¼ teaspoon salt
- ⅛ teaspoon black pepper
Butter Blend
- 10 tablespoons unsalted butter, softened
- 1 teaspoon minced garlic (1-2 cloves)
- ½ teaspoon Worcestershire sauce
- ⅛ teaspoon dried thyme
- ½ tablespoon chopped parsley
- Pinch of salt and black pepper
Instructions
- Caramelize the onions: Place the sliced onion, 2 tablespoons of butter, ¼ teaspoon salt, and a pinch of black pepper in a skillet over medium heat. Cook the onions, stirring frequently, for about 45 minutes until they have caramelized into a deep brown, sweet flavor.
- Cool the onions: Remove the skillet from the heat and let the caramelized onions cool for 5-10 minutes to prevent melting the butter in the next step.
- Blend the ingredients: In the bowl of a food processor, add the remaining 10 tablespoons of softened butter, the cooled caramelized onions, minced garlic, Worcestershire sauce, dried thyme, chopped parsley, and a pinch of salt and pepper. Pulse until the mixture is completely smooth and evenly combined.
- Refrigerate the compound butter: Transfer the blended butter to a container or mold and refrigerate it until firm and ready to serve. This allows flavors to meld beautifully and gives a perfect spreadable consistency.
Notes
- Worcestershire sauce adds a subtle umami flavor; substitute with soy sauce or omit for a different flavor profile.
- Caramelizing onions slowly is crucial for developing the deep, sweet flavor in the butter.
- Store the compound butter in an airtight container in the refrigerator for up to two weeks or freeze for longer storage.
- This butter pairs wonderfully with grilled meats, roasted vegetables, or melted on warm bread.
