How To Roast Garlic Cloves In The Oven

There are so many recipes you can try using roasted garlic and it’s so simple to do. Here is an easy guide on how to roast garlic at home, in the oven.

Garlic is a well used ingredient in our kitchen and for good reason. Garlic adds so much flavour to many different types of food. The reasons for using garlic do not stop at taste and flavour either. Garlic is claimed to have many health benefits too.

However, as with anything, there is always a downside. The dreaded garlic breath that follows you around the day after eating garlicky foods can be enough to deter many people from using it in large amounts. It can also cause digestibility issues for some people too.

For these reasons, let me introduce you to roasted garlic. Who’d have thought that an ingredient could change so dramatically after 45 minutes in the oven with very few added ingredients.

Garlic becomes something completely different when roasted and I guarantee you won’t be disappointed with the result at all.

Why Use Roasted Garlic?

Raw garlic is fine as it is, right? So why bother roasting it? Let me tell you, the aroma that wafts around the kitchen as the garlic bulb caramelises in the oven, is enough to try this at least once.

Here are some other reasons:

  • It has a milder taste than its raw counterpart, meaning you can eat more in one sitting.
  • When roasted, garlic will caramelise slightly, releasing the sugars within and making the garlic sweeter with a slightly smoky taste.
  • It is more digestible.
  • You are much less likely to get garlic breath after eating it.

Recipes That Use Roasted Garlic

Whenever there is a recipe that uses garlic, you can usually substitute it for the raw counterpart. Garlic Bread for instance, will have a different twist when you use roasted garlic in the recipe. Garlic Aioli is another one.

Tips and Guidance

You can use parchment paper instead of foil to wrap the garlic bulbs, if you’d prefer. You can also place them in an oven proof dish with a lid on top.

You can substitute olive oil for another cooking oil. Vegetable oil will work fine.

Salt and Pepper can be used or omitted, depending on your preferences. You can also add some herbs such as rosemary or thyme to the parcels before roasting, for extra flavour infusion.

When you remove the garlic from the oven, the cloves will be soft and caramelised. Allow them to cool a little before handling.

You can store your roasted garlic in the fridge for up to 3 days or try pureeing it and storing in ice cube trays in the freezer.


How do I store Roasted Garlic?

You can store it in the fridge in an airtight container, for up to 3 days. Alternatively, roasted garlic can also be frozen and kept for 3 months.

How much roasted garlic should I use to replace raw garlic?

The flavour of roasted garlic is milder and more sweet and the amount you use is dependent on how much roasted garlic taste you want to impart. You can happily double or even triple the amount without overwhelming most dishes.
