Roasting your garlic is a must for this recipe, which is why we’ve included a step-by-step method for foolproof roasted garlic. Once you roast the garlic, the rest of the recipe comes together in a flash.
You won’t believe how easy it is to take a stick of butter from boring to restaurant-quality with just a few simple ingredients. Our main ingredient, the roasted garlic, adds so much depth and flavor to the butter, while the fresh herbs brighten everything up.
For this roasted garlic spread recipe, gather:
- A bulb of garlic
- Olive oil
- A stick of unsalted butter
- Kosher salt
- Black pepper
- Fresh herbs (I used fresh rosemary, chives, and parsley)
Substitutions & Optional Add-Ins
Whether you’re looking for a simple roasted garlic butter for bread or a more complex flavored butter for a specific dish, this butter can do it all. There are a number of swaps and additions you can make to customize the butter to your liking. Here are a few suggestions:
- Butter: I use unsalted butter in this recipe to control the amount of salt I’m adding, but feel free to use salted butter instead. Just be careful when adding additional salt if you’re using salted butter. This roast garlic butter recipe also works well with vegan butter.
- Fresh herbs: Fresh, fragrant herbs take this roasted garlic butter spread to the next level and give it that fancy restaurant-quality taste. You can use your favorite herbs or any you have on hand, but I recommend fresh parsley, rosemary, thyme, chives, or basil. As a rule of thumb, use two teaspoons of finely chopped fresh herbs per stick of butter.
- Spices: Amplify the flavor of your butter by adding some spices. You can cater the spices to a specific recipe’s flavor profile, so feel free to get creative. Sweet paprika, oregano, or a pinch of red pepper flakes are great additions that complement a variety of recipes.
- Flaky sea salt: Topping your compound garlic butter with flaky sea salt brings out all the delicious flavors of this recipe and adds the perfect finishing touch. Trust me on this one. My favorite brands of sea salt are Maldon Sea Salt Flakes and Jacobsen Flake Finishing Salt.
- Parmesan Cheese: I usually add a few tablespoons of parmesan cheese if I am using it to make my Rosemary Mashed Potatoes.
How to Make Roasted Garlic Butter?
Once you roast the garlic, all you have to do is add in the rest of the ingredients and give it a mix! We’re using our oven-roasted garlic method for this recipe, but if you’re in a pinch, you can cut roasting time in half by following my Air Fryer Roasted Garlic recipe. I even have a Roasted Garlic Without Foil version! Here’s how to make this easy recipe:
- Preheat the oven: Set your oven temperature to 400 degrees F.
- Prep the garlic: Slice the top of the garlic with a paring knife, so the cloves are exposed and place the bulb on a piece of foil. Add a drizzle of olive oil on top of the cloves.
- Wrap the garlic: Wrap the whole head of garlic tightly with foil so that it resembles a pouch. Place on a baking sheet or in a baking dish.
- Roast: Roast the garlic in the 400-degree oven for 40 minutes. You’ll know the garlic is done if it appears soft and lightly caramelized (be careful when opening the aluminum foil pouch, as it will be hot). If it doesn’t appear done, wrap the garlic back up and roast for another 5-10 minutes.
- Remove the cloves: After letting the garlic cool for at least 20 minutes, remove the roasted garlic cloves by gently squeezing the bulb from the root end until each individual clove is squeezed out. Discard the outer skin and place the cloves in a bowl.
- Mash the garlic: In a small bowl or on a cutting board, use a fork to mash the roasted garlic until it’s pureed.
- Add the remaining ingredients: To the same bowl, add the softened butter, salt and pepper, and (optional) chopped herbs. Mix until well combined, or blend in a small food processor.
How to Roll Compound Butter into a Log?
Now that you know how to make roasted garlic butter, you can stop there and store garlic butter in a bowl. However, I find it easy (and fun) to roll my butter into a log. Doing so makes for easy slicing, and, as a bonus, it looks extra fancy! Follow these simple steps:
- Shape the butter: Place the roasted garlic compound butter on a piece of plastic wrap or parchment paper and shape it into a cylinder. Wrap it up tightly so it holds its shape.
- Cool: Place the butter log in the fridge and cool for at least three hours. To serve, unwrap the butter, cut it into slices, and use it in your favorite recipes!
How to Use Garlic Butter?
You can use this homemade roasted garlic butter anywhere you’d use regular butter, so the sky’s the limit if you’re a butter fanatic! This flavorful butter is the perfect finishing touch to make any meal or snack come to life. Here are a few suggestions to get you started:
- Spread it on crusty bread: It’s no secret that you can use this garlic compound butter for garlic bread. There’s nothing better than melty, garlicky butter spread on crusty, fresh bread. This butter pairs beautifully with my No Knead Bread, Olive Bread, French Bread, or your favorite dinner rolls!
- Use it to flavor fish: Fish and garlic butter are a match made in heaven! This roasted garlic and herb butter really elevates my Grilled Mahi Mahi, and my Grilled Shrimp Skewers aren’t complete without some garlicky, buttery goodness.
- Serve over steak: Many restaurants use roasted garlic butter for steak, and it’s always such a treat to order a buttery, sizzling steak from your favorite steakhouse. But with this delicious butter, you can bring those steakhouse flavors right to your own kitchen! Slather as much butter as you desire on Reverse Sear Beef Tenderloin or Grilled Steak.
- Add to roasted vegetables: In my opinion, roasted veggies aren’t complete without a liberal helping of butter. Roasted garlic herb butter adds a more caramelized flavor to roasted mushrooms, so be sure to pair this butter recipe with my Roasted Portobello Mushrooms, Roasted Shiitake Mushrooms, or my Sauteed Asparagus and Mushrooms. Or, transform my Southern-inspired vegetable recipes, such as these Garlic Butter Green Beans, my Mashed Potato Casserole, or Air Fryer Corn on the Cob, into true comfort food by topping them with a dollop of garlic butter with roasted garlic.
How to Store & Freeze
If you still have some extra homemade garlic butter on hand after spreading it on everything you can think of (we won’t judge), then feel free to pop your leftovers in the fridge or freezer so you can enjoy them another day! Here are my storage recommendations:
- Make Ahead: If you want to save time, you can roast your garlic a day in advance. Simply combine your roasted garlic with butter when ready to serve.
- Store: If stored either tightly wrapped or in an airtight container, this simple compound butter recipe stays fresh in the fridge for up to three days. Be sure to consume your butter within this time period, as a foodborne illness called botulism can occur if garlic sits for too long in an oxygen-free environment. Try making a smaller batch of this recipe or make only one batch at a time to avoid waste and ensure you can consume the butter within the three-day period.
- Freeze: Freeze your rosemary garlic compound butter for up to a month, either tightly wrapped or in an airtight container.
- Thaw: Thaw your butter from frozen by taking it out of the freezer an hour before you expect to serve it. Make sure only to thaw the amount you want to use.
Butter has various health benefits and is a great source of vitamins A and E, which support skin health, the immune system, eye health, and heart health. Garlic is also very nutritious, and a major health benefit of garlic lies in its immune-boosting properties.
Botulism, a foodborne illness, can occur when a homemade garlic-in-oil mixture is stored in a room-temperature environment. Bottled or otherwise enclosed raw garlic creates an oxygen-free environment that supports bacterial growth, which can lead to botulism. To reduce the risk of botulism, per food safety guidelines, always store homemade garlic mixtures, including garlic butter, in the refrigerator and consume them within three days.
There are about two to three tablespoons of garlic in each garlic clove, depending on the size of the garlic bulb.
Yes, you can. However, if you do so, be sure to adjust the amount of salt you use in the recipe below.
Yes, you can. However, keep in mind that it takes much less time to roast pre-peeled garlic, so be sure to adjust the roasting time accordingly.

- Shape: You can use your garlic butter right away or shape it into a cylinder (make it a compound butter) for better presentation and portion control. To do so, place the garlic butter on a piece of plastic wrap (or parchment paper), shape it into a cylinder, and wrap it tightly. Place it in the fridge for at least 3 hours before using. When ready to serve, unwrap and cut it into slices and use in your recipe.
