Ingredients

Ingredients as in the recipe card viewed from above.

The key ingredients for this recipe are in the name – garlic and butter. These are the main flavors and need to be fresh and of good quality.

  • Garlic bulbs – Choose firm bulbs that haven’t got green sprouts growing from the top. Give the bulb a gentle squeeze. You don’t want to feel any squishy bits or hollows where the garlic has dried out.
  • Olive oil – Regular olive oil is fine.
  • Unsalted butter – Buy the best butter you can afford or enjoy the taste of. This recipe is based on butter so it needs to be good! European style butter is ideal!
  • Salt – Regular fine salt is all you need.
  • Parsley – Fresh parsley is best for this recipe. Dried parsley flakes don’t have much flavor.

See recipe card for quantities.

Two whole garlic bulbs cut in half with one showing the inside cross section.

Hint: Have the butter at room temperature so that it blends easily with the roasted garlic. However don’t be tempted to soften the butter in the microwave. Melted butter separates so won’t produce good results!

Substitutions

  • Olive oil – instead use another oil or fat that you prefer – avocado oil, peanut oil or even a smear of softened butter.
  • Unsalted butter – use salted butter instead but remember to leave out the salt. Once blended, taste the butter and adjust the salt if needed.
  • Air fryer – garlic can be roasted in an air fryer. Prepare as specified in the recipe then air fry at 400ºF/200ºC for 20-25 minutes.

Variations

  • Spicy – add red pepper flakes to give this recipe a little bit of heat.
  • Herby – substitute or add extra chopped fresh herbs like rosemary, basil or chives
  • Cheesy – add a spoonful or two of grated Parmigiano Reggiano or Parmesan cheese.

Equipment

Fortunately, this homemade garlic butter can be made without any special equipment. If you have a sharp knife, a small bowl, some aluminum foil as well as a fork for mashing and a spoon for stirring, you can make this recipe! 

A food processor can be used to blend the ingredients however I haven’t found that it’s necessary. 

Storage

Roasted garlic butter will keep in the fridge for at least a week. Wrap it with several layers of plastic and then in an airtight container to prevent it from absorbing odors and also to prevent the garlicky smell from getting into everything else.

For longer storage, it can be frozen for up to three months. Be sure to wrap the compound butter well in plastic and then pop it into a heavy-duty freezer bag or an airtight container.

Top tip

Softened butter with green herbs in a jar and also spread onto bread on a wooden board.
  • Roast garlic thoroughly. Roasting garlic takes longer than you probably think. Preheat the oven and wrap the garlic well in foil to protect it from the long roast.
  • Use good quality butter. You will notice the difference.
  • Make sure the butter is soft but don’t allow it to melt. Butter that has been melted will separate into fat and water and won’t be creamy like regular butter.
  • Chop the parsley very finely. By doing this, it is evenly spread throughout the butter.
  • Taste! That’s right! Taste the butter and adjust the seasoning. You might even like a little bit of freshly ground black pepper.

You’ll love roasted garlic butter melted on freshly cooked ricotta cavatelli or fagottini creating an instant sauce. Use it on my ciabatta garlic bread instead of the regular garlic butter.

    My son who is a chef taught me this recipe, then I saw it here. It is really good and well worth making. He uses all sorts of herbs, whatever he has at hand but mainly parsley. Sometimes he adds grated Parmesan. Need to allow nearly an hour for the garlic to roast and cool so you can squish it out. Highly recommend this recipe.

    1. I agree with your son Sophie, I like parsley! Yes, it can take as long as an hour to roast the garlic but that depends a lot on your oven and how far you want to take the garlic. I recommend checking at the 45 minutes mark. Thanks so much for taking the time to comment!
