I was looking for a garlic flatbread recipe yesterday (as you do!) and came across a very intriguing suggestion… that it was possible to ‘roast’ garlic in the microwave, in just a few minutes. Could it be true? If it was, it would save quite significantly on the time and energy involved in roasting in the oven – typically 45 minutes to an hour, fine if you’re organised and remember to put your little tinfoil parcels in with something else, but irritating and inefficient if you find yourself wanting some right now!
The instructions I’d found were only a tantalising hint, unfortunately – vague on both the technique and on power and timings. So I had a little google, and discovered that apparently lots of people were doing very similar things. Convinced now that I was reinventing the wheel, and that everyone else already knew about this trick and just hadn’t bothered to tell me, I tweeted to this effect. What was said in response surprised me – apparently, no one else had heard about it, either. So, I promised to investigate and then blog my findings. True to my word then, here goes!
Obviously, you’re not really roasting the garlic, since this requires the application of direct heat. Consequently you won’t get the caramelisation which true oven-roasted garlic gains (well, you can, but more of this later!). The process is closer to steaming, but produces a soft, sweet, cooked garlic very suitable for using as a substitute for true roasted garlic if you’re short on time and organisation – and there are ways to cheat the last mile and get that caramelisation, too.
For your microwave ‘roast’ garlic, you require -
- One or more garlic bulbs (I suggest you start with one, until you’re happy with the process),
- A splash of water and olive oil,
- A microwave proof dish with suitable loose-fitting lid (or some cling film), and
- A microwave, obviously.
Slice the top off your bulb of garlic, at a level where you’re just ‘scalping’ all of the cloves of garlic inside.
Add 2 or 3 tablespoons of water to the bottom of your bowl (enough to cover the bottom about 5mm deep), add your clove of garlic cut side up, and drizzle over some olive oil. Cover loosely – don’t seal, and if you’re using cling film, leave a small opening on one side. Pop the whole lot in your microwave.
Now – all of these directions are for *my* microwave, which is a very standard UK-type category E (800W) device. Your microwave may be slightly (or very!) different – even if it claims to be the same – so a little experimentation is going to be required!
Start by heating the garlic for 1 minute on full power. Then take it out of the microwave, remove the cover (carefully, as there will be a lot of steam!) and give the cut surface of the garlic a speculative prod with the point of your knife. It should give very slightly, and have changed colour subtly from white to a slightly translucent creamy shade.
It probably isn’t convincingly soft yet, though, so pop it back in the microwave and this time give it 30 seconds on full. Take it back out and repeat the poking process. Depending on the size of the cloves in your garlic, it may well be ready by now. If the surface of the garlic seems reasonably soft (it won’t be pulpy), and the cloves are coming away from their inner skin, then it’s worth popping a clove out to test.
If you can crush the clove easily with the handle of a spoon, then it’s done. If not then give it a little longer. My bulb had a couple of quite big juicy cloves, so I put it back in, but only for a final 15s. So total time in the microwave, for me, of 1 minute and 45 seconds.
After letting it cool for a few minutes, I popped out one of the bigger cloves, and it squashed really easily. Job done.
Taste a little piece – it has become quite unlike raw garlic, instead mild, sweet and aromatic, just like roast garlic. Yes, it lacks a little note of caramelisation – but we’ll get to that!
Here’s the really important thing. ONCE THE GARLIC IS SOFT, STOP!
Because, these photos aren’t from my first attempt. The first attempt I made turned out like this. I gave it two initial 1 minute blasts in the microwave, and so pleased was I with the progress it got another 30 seconds. A nice toasted smell started to develop, and a golden colour on the edge of the garlic. I was delighted. Right up until I gave it a poke and it was rock hard. So let my mistake stand for all of you, and we won’t have to sacrifice too many perfectly innocent garlic bulbs!
What do you do with it now? Well, if you want something closer to ‘real’ roasted garlic, heat up your oven, wrap up your garlic in a little tinfoil parcel with an extra drizzle of olive oil, and bake it for 10 – 15 minutes at 180C until it takes a little colour. Much quicker! An even ‘cheatier’ approach might be to heat a little olive oil in a frying pan and just brown off the cut surface gently until golden. No one will ever know!
But most of the time, roast garlic is going into something else, anyway. As I said, all of this came about because I wanted to make some garlic bread to go with pasta for dinner. The one I chose to make is based on this recipe from BBC food.
To make one roast garlic and rosemary bread (serves four generously as a side dish) -
- 250g strong white bread flour
- 150ml warm water
- 1 (7g) sachet of dried yeast
- 1 tbsp olive oil
- 1/2 tsp sugar
- 1 bulb of garlic, ‘roasted’ as above
- 75g unsalted butter
- 3 or 4 sprigs of fresh rosemary
- A generous pinch each of salt and freshly ground pepper
Weigh your flour into a bowl, and make a well in the centre. In a measuring jug, combine the water, oil, sugar and yeast, and stir in gently. Now pour the liquid, a little at a time, into the flour, and combine into a dough.
Knead the dough for about 5 minutes, until it becomes silky and elastic, and set aside to rise at room temperature in an oiled bowl until well risen about tripled in size is ideal). This will take an hour or so, more if your room temperature is low!
In the meantime, you can prepare your microwave ‘roast’ garlic as described earlier, and allow it to cool. Once you can handle the garlic comfortably, pop all the cloves out of the bulb and crush them with the flat blade of a knife, leaving a little texture (you’re not making garlic puree).
Finely chop your rosemary (stalks removed), and mix this, the garlic, salt & pepper into your softened butter. My butter lives at room temperature, but if yours is coming out of the fridge, a 10s blast in the microwave (with foil wrapper removed!) will soften it up and make it easier to work with. You’re pretty much all set, so go and do something else while the bread dough rises.
Once your dough is well risen, find a baking sheet or shallow-sided baking tray and line it with baking parchment. Tip the dough out onto a well oiled work-surface, and knock it back gently, shaping it to the size and shape of your baking sheet. It will be quite a thin layer, probably about 1cm thick. It doesn’t need to be perfect and I certainly wouldn’t use a rolling pin, you should be able to stretch and shape it with your hands just fine. Transfer carefully to the baking sheet – it doesn’t matter if it gets a bit ‘crumpled’ looking!
Now spread your flavoured butter over the surface. Again, use your fingers, blobs and knobs are fine, you’re not aiming for an effect like icing a cake, but try and share the butter around reasonably evenly. Finally, stab the bread all over with a fork, and leave to prove for another 30 minutes or so until the dough is looking a little puffed up again.
When you’re happy, heat your oven to 230C and once it’s up to temperature, slide in the baking sheet. You’ll want to watch this bread reasonably carefully, because it’s quite thin and will bake reasonably quickly, and there’s a risk of the garlic burning and taking on a bitter flavour if your oven has nasty hot-spots (mine does, sadly!). Turn the bread if you notice it starting to brown unevenly. Don’t hesitate to turn the oven down to ~190C if the surface seems to be browning too fast. It should take about 15 minutes to be lovely and golden brown all over.
This was a glorious accompaniment to a pasta supper. The garlic acquires all of that sweet caramelised flavour during the baking of the bread, so there’s no loss at all from the microwave roasting process compared to a more traditional approach. After baking, the garlic is sweet and aromatic with none of the raw hot flavour you get have from raw garlic in garlic bread. I will definitely be making this one again.
There are some obvious variations, which I think would work very well with this bread. Adding some finely chopped, caramelised red onions to the butter would work very well, I think. You could also throw a handful of grated parmesan into the butter mix, which would melt beautifully into the surface. You’re really in pizza-bread territory here, and the world is your oyster! Experiment!
The microwave garlic roasting technique is the real star of this show, for me, though. One of those accidental discoveries which really will change the way I cook. I recommend you give it a try!
