Roasted Garlic and Herb Compound Butter

Roasted Garlic and Herb Compound Butter

Published September 19, 2026

Creamy whipped butter infused with roasted garlic, fresh herbs, and lemon zest—a make-ahead condiment that melts into steaks, vegetables, and bread.

Roast the garlic bulb cut-side up, drizzled with a pinch of olive oil and salt, covered loosely with foil at 400°F for 30–35 minutes until golden and very soft. Soften butter at room temperature for 15–20 minutes until it yields easily to a fork but still holds its shape—too warm and it will be greasy; too cold and it will not blend smoothly.

Substitute dried herbs (½ tsp each thyme and parsley, ¼ tsp rosemary) if fresh are unavailable, but reduce amounts slightly as dried herbs are more concentrated. Roll the finished butter in plastic wrap into a log about 1 inch in diameter, twist the ends, and refrigerate for up to 2 weeks or freeze for up to 3 months. Slice into ½-inch rounds to serve.

Measurement units
  • 1 whole garlic bulb
  • 8 oz unsalted butter
  • 3 tbsp fresh parsley
  • 1 tbsp fresh thyme
  • 1 tsp fresh rosemary
  • 1 tsp lemon zest
  • ½ tsp lemon juice
  • ½ tsp kosher salt
  • ¼ tsp black pepper

Instructions

Roast the garlic
Preheat oven to 400°F.
Cut garlic bulb in half horizontally, place cut-side up on a small baking sheet, drizzle lightly with olive oil, and season with a pinch of salt.
Cover loosely with foil and roast until the garlic is golden and very soft, about 30–35 minutes.
Remove from oven and let cool for 5 minutes until cool enough to handle.
Extract roasted garlic and prepare herbs
Squeeze or scoop the soft roasted garlic cloves from their skins into a small bowl; discard the skins.
Mash the roasted garlic cloves with a fork until smooth.
Finely chop fresh parsley (3 tablespoon), fresh thyme (1 tablespoon) leaves, and fresh rosemary (1 teaspoon) leaves; set aside.
Finely grate lemon zest (1 teaspoon) and measure lemon juice (½ teaspoon).
Blend butter with garlic and herbs
Place 8 oz softened unsalted butter (8 oz) in a mixing bowl.
Whisk or beat the butter until creamy and light, about 1–2 minutes.
Fold in the mashed roasted garlic, chopped parsley, thyme, rosemary, lemon zest, and lemon juice until evenly distributed.
Season with kosher salt (½ teaspoon) and 0.25 tsp freshly ground black pepper (¼ tsp); taste and adjust seasoning as needed.
Equipment: mixing bowl
Shape and chill
Lay out a sheet of plastic wrap or parchment paper and spoon the compound butter onto it in a line.
Roll the butter into a log about 1 inch in diameter, twist the ends to seal, and refrigerate until firm, at least 1 hour.
Equipment: plastic wrap or parchment paper
Serve
Unwrap the chilled butter log and slice into ½-inch rounds.
Place a slice directly on a hot steak, grilled vegetables, or warm bread to melt and serve.
