Roasted garlic and herb compound butter is a blend of butter with roasted garlic and fresh herbs. Compound butter is great for topping steaks, baked potatoes, spreading onto dinner rolls, and more.
What exactly is compound butter? Compound butter is a combination of butter with other added flavors like herbs and spices. It is used to enhance the flavors of a prepared dish, just liked you'd use a sauce or condiment.
This compound butter is enhanced with roasted garlic cloves and fresh herbs, like parsley, oregano, thyme, and rosemary. Customize your compound butter with any fresh herbs you have on hand for a unique flavor.
This roasted garlic and herb compound butter is perfect for topping a grilled steak just before serving. You can also spread compound butter onto dinner rolls or bread, mashed or baked potatoes, or steamed veggies.
Ingredients and substitutions
Unsalted butter and salt can be substituted with salted butter. You can also omit the salt entirely if you do not want to add additional salt to your prepared dishes.
Any fresh herbs you have on hand can be used in this recipe. I used a combination of parsley, thyme, and rosemary in my compound butter. Oregano, chives, or basil would also be great choices. I suggest choosing two or three for a well rounded flavor.
One head of garlic will be needed for this recipe. This may seem like a lot, but roasting garlic mellows the flavor, making it a lot less harsh than raw garlic. It's also much easier to digest and has a lovely caramelized flavor.
If you've never roasted a head of garlic before, it's surprisingly simple to do. First, you'll want to peel off any excess layers of paper from the outside of the garlic.
Next, slice about ¼ inch of the top off (the wide, root side), to expose the individual garlic cloves.
Make a little bowl of foil to set the head of garlic in, which will help hold the garlic cloves together and upright. Drizzle the top with olive oil, then cover completely with foil.
Your garlic is done roasting when it is soft throughout (test by piercing through with a fork) and has a browned, caramelized color. This usually takes about 40 to 50 minutes in a 400 degree oven, but you can roast your garlic for even longer for a more caramelized flavor.
Ways to use compound butter
There are many ways to use your roasted garlic butter. Simply add to the top of a prepared dish to instantly add flavor. Here are a few of my favorites:

This roasted garlic butter is also excellent for making a homemade garlic bread. Spread onto thick sliced Italian bread and toast until golden.
