Oven Roasted Garlic

If you’ve never roasted garlic before your life is about to change forever. When you roast garlic you completely change to flavour and texture. It caramelizes and turn gorgeously sticky and sweet. The texture turns silky and soft. It’s just an all round good time.

We’ll chat about how to use it in just a sec, but first let’s see how easy it is to make.

How to Roast Garlic in the Oven (quick summary)

  1. Slice the tip off your garlic bulb to expose the cloves.
  2. Place on foil and drizzle with olive oil.
  3. Wrap.
  4. Place in the oven until deep golden, sticky and caramelized.
  5. Unwrap and allow to cool for a few mins.
Top Tip #1 – Low and slow is key! You’ll roast the garlic at 180c/356f for up to an hour to get best results. Don’t be tempted to crank up the heat to speed things up, the garlic won’t caramelize properly.

Top Tip #2 – Use a fresh bulb of garlic, not the one you just found knocking around at the back of your cupboards. Older garlic tends to come out more dry and slightly more chewy. Fresh is best!

From there it’s just a case of peeling away any outer layers from the garlic bulb and squeezing out the roasted garlic.

Roasted Garlic Butter

One of my favourite things to do with roasted garlic is to make roasted garlic butter. Perfect to melt on a steak, even better on baked bread!

How to make Roasted Garlic Butter (quick summary)

  1. Mash roasted garlic with salt until completely smooth.
  2. Add butter, parsley, olive oil and seasoning.
  3. Mash until completely smooth.

Mashing the roasted garlic with salt is great to smooth out the garlic if there is any tough or chewy bits!

  • Chopping Board
  • Sharp Knife
  • Aluminium Foil

Ingredients (check list):

  • 1 large bulb of Garlic
  • Olive Oil


  • Slice the tip off the garlic bulb to expose all the cloves (only the tips, don't slice off too much).
  • Drizzle with olive oil (1 tsp should suffice).
  • Wrap in foil and place in the oven at 180c/356f for 45-60mins, or until knife tender, golden brown and caramelized. Don't be tempted to whack up the temp, low and slow is the aim of the game.
  • Leave for a few minutes to cool down, then peel away the outer layers. Squeeze out as much as you can, making sure the outer peel doesn't mix in.
  • Use as a spread or in a butter, stir through a cheese sauce or even in a dip!

Quick 1 min demo!


a) Garlic - This works best with fresh garlic, step away from the garlic you've just discovered in the back of your cupboards. Chances are that's already started to firm up, meaning it'll come out quite dry and chewy.
b) Smooth - The garlic should squeeze out like a smooth paste. If for whatever reason it's a little firm/lumpy then squeeze it on to a flat surface, add a pinch of salt and smash with a fork. This is what I actually do with my Roasted Garlic Mac and Cheese to ensure it's as smooth as possible.
c) Measurements - 1 large bulb will give you about the same as two small bulbs. You're looking at around 1 heaped tbsp's worth of roasted garlic.
d) Time - Low and slow is the aim of the game, so don't whack up the heat to try and speed things up. You're looking for a deep caramelization, it should be sticky when you peel the foil away. You can check multiple times throughout to check how it's getting on.

    Love this post! Roasting garlic itself can be overlooked, but a great way to make use of it while cooking to bring out flavors.
