Cut the garlic in half. Spread olive oil evenly over each cut half.
Rejoin the garlic bulbs and wrap tightly in aluminum foil.
Roast for 45 minutes or until golden brown and caramelized.
Cool for 10 minutes or until you can handle it.
Open the foil and let the garlic cool until you can handle it.
Squeeze the garlic bulb pushing the roasted garlic into a small bowl. Or use your fingers to take the soft garlic from the skins. Let the garlic cool completely.
Add the butter, parsley and salt to the cooled roasted garlic.
Use a fork to mash the garlic into the butter and combine all the ingredients thoroughly.
Use immediately or scrape the compound butter onto a piece of non stick parchment paper. Use the paper to form the butter into a log then twist the ends to seal. Refrigerate for at least 2 hours until firm. Slice to serve.
Notes
Tips for Success
Ovens differ so your garlic may take longer to roast. Open the foil to check.
Use good butter that you like the taste of.
The butter should be soft but avoid melting it. Melted butter separates.
Finely chop the parsley so that it is evenly distributed throughout the butter.
Taste to check the seasoning. You may need to adjust the salt for your taste.
