This Roasted Garlic Pesto Sauce is made with oven-roasted garlic in place of regular garlic. The roasted garlic caramelizes in the oven, creating a creamy, smooth flavor that adds a delicious twist to your traditional pesto. Mild and perfect for those sensitive to raw garlic, you'll want to put this on everything!
Pesto sauce is a summer staple in our house. I make big batches in late summer when my basil pots are overgrown. I then freeze it so I can enjoy it all winter long. Pesto is easy to make. Just throw all the ingredients in a food processor and presto- you've got pesto!
Traditional Italian pesto is made with raw garlic. However, the taste of raw garlic isn't for everyone. Roasting the garlic in the oven mellows out the sharp flavor found in garlic and makes it easier to digest. Plus, no garlic breath!
Bonus- roasted garlic can be used in place of regular garlic for just about anything. Its creamy, nutty, and smooth flavor is rich and pairs perfectly with meats, fish, soup, pizza, and so much more. So make a big batch today- you know you want to!

What is pesto?
Authentic Pesto is an Italian sauce made up of fresh basil, garlic, pine nuts, cheese (such as Parmesan), olive oil, salt, and pepper. Traditional pesto is made using a mortar and pestle (hence the word pesto- meaning "to crush"), but modern pesto is made using a food processor for easy blending.
Basil pesto is the most common; however, these days, you will find endless variations of pesto such as kale, spinach, and arugula, to name a few. Either way, they are all easy and delicious to make.
What you will need
- Basil- Fresh basil.
- Roasted garlic- Instead of the usual raw garlic, you will first roast the garlic in the oven until it's nice and carmelized.
- Grated cheese- Parmesan is common, but you can use any hard cheese such as Locatelli or Pecorino Romano.
- Nuts- I often use pine nuts, but they are expensive. I have made pesto with walnuts, pecans, and pistachios, so any of those will work. To enhance their flavor, try toasting the nuts first. Sometimes you can even buy nuts already toasted.
- Olive oil- Choose a good one with a bold, fruity flavor.
- Salt and pepper
Equipment
You will need some aluminum foil for roasting the garlic. For the pesto, you will need a food processor or blender. Because this makes a small batch, I prefer my food processor for mixing.
How to make roasted garlic pesto sauce
Pesto is very simple to make. Roasting the garlic is an added step, but so worth it.
Preheat the oven to 425℉. Remove the papery skin from the garlic head. Using a knife, cut ¼ -½ inch off the top of the garlic, exposing the cloves. Drizzle with olive oil, and wrap in aluminum foil.
Roast the garlic in the oven for 40-50 minutes, until the garlic is golden brown, soft and caramelized. Allow to cool slightly before handling.
Add all the ingredients to a food processor, and pulse on high until blended, adding more olive oil as needed to achieve the consistency of a sauce.
Use sauce immediately or store in a tight fitting jar.
If you plan on freezing your pesto, don't fill your jars to the top. You want about a half inch at the top because the sauce will expand as it freezes.
👩🍳Pro tip
Try toasting your nuts for added flavor. You can toast them in a non-stick pan for a few minutes on medium. Just watch them closely, so they don't burn!
