I’ve always made roasted garlic in the oven, which can take an hour or so.  But, did you know you can make roasted garlic in the microwave in just a few minutes? I just love garlic, especially roasted garlic, and this method makes it quick and simple when you need to add it to a dish like Garlic Mashed Potatoes.  

How to make Roasted Garlic in the Microwave

I make up a batch at a time and keep it in the fridge in some olive oil.  It’s amazing as a burger topping or in mashed potatoes, chopped up into garlic butter sauce, spaghetti, meatballs, and more.  It’s so easy to make. 

How do you Roast Garlic in the Microwave?

My microwave is 1000 watts, so the time might be different for you.  You can download the FREE Microwave Power Conversion Time Chart from the banner at the very top of the blog or you might need to experiment.  It took me a few tries to get the right time.

After it’s cooked, you want the garlic to easily squeeze out of the cloves so that it’s soft and can easily be mashed.  

Making roasted garlic this way won’t be quite so aromatic or turn very brown as when roasted in the oven.  The flavor also won’t be as pungent.  I still found it absolutely delicious, especially smashed on a piece of crusty bread.  It’s a total time saver shortcut when you need roasted garlic or just regular garlic in a recipe because usually it takes about an hour to roast garlic in an oven.  

Depending on the recipe, you might need to mash the garlic or mince it or chop it.  All of that will be super easy once the garlic is softened by roasting. 

How do you store freshly Roasted Garlic?

I use a small plastic container and gently squeeze all the garlic pieces I can out of the garlic head.  The garlic is soft, so it can sometimes be a challenge to squeeze them out whole and not squished.  Sometimes, they do squeeze out squished or mashed, but those garlic pieces are definitely still usable. 

Once you’ve squeezed them all out, make sure none still have the papery skin on them.  Then throw all the papery part of the head away.  

Douse the garlic in olive oil.  I usually fill the container so that the garlic is completely covered in olive oil.  Keep the container tightly covered and in the fridge. The roasted garlic will last about 1-2 weeks.    

Don’t waste the olive oil when you’ve used up all the garlic because you’ll then have amazing Garlic infused Olive Oil, which tastes amazing and is perfect to add to Italian food or salad dressing.
