Hi! I am writing up the recipe for this new easy creamy roast garlic and lemon pasta sauce. It pretty much contains all my favourite flavours in one sauce! Roast garlic is added to foamy butter with lots of pepper, lemon and lemon zest then rounded off with cream and parmesan. I have used a homemade orecchiette but it will work with absolutely any pasta shape!

Tips for the best roast garlic and lemon pasta sauce

Brown the butter a touch - If I ever use butter as the base for a sauce I let it gently brown before adding anything else. It is a way to get a good flavour base going. Just don't let it burn or get to hot.
Use fresh lemon! Please don't use bottled lemon juice, fresh is best every time and nothing else will do!
Roasting the garlic - You want to roast the garlic so it is just starting to brown and caramelise. Keep checking it every 5 or 10 mins if it isn't done by the 45 min mark. Make sure you let them cool before squeezing the cloves out!
If using dried pasta - undercook it slightly. I really do love letting the pasta bubble away in the sauce for a minute or two so undercook your pasta by a minute or so. If using an orecchiette or gnocchi sardi then you don't need to worry as it's pretty hard to overcook fresh shapes like that.
Grating the parmesan - I usually say to grate your parmesan with a microplane (or the star side of a box grater). It creates much finer strands that melt into sauces much easier.
Save some pasta water - I always transfer my pasta straight into the sauce from the pot with a spider strainer so the pasta water is left behind for me to use as I wish. You can cut out the step of using a colander and washing all that liquid gold down the sink. You never know how much you will need!

How to roast whole garlic bulbs

Roasting whole garlic bulbs is not only super easy, it's crazy delicious. It caramelises and turns the garlic into a sweet creamy ingredient you can add to anything! It is really simple, here is the process.

Preheat your oven to 200c (390f)
Peel the outer papery layers off the bulbs (I actually forgot to do that here!) It just makes squeezing the garlic out at the end much easier.
Slice the top off, just enough to expose the tops of the cloves.
Drizzle with olive oil and wrap up in aluminium foil.
Roast in the oven on a tray for 40 - 50 mins. You want the top to look brown and caramelised.
Once it's cooked, let it cool enough to touch.
Squeeze all of that delicious garlicy goodness out.

Why pasta water is your best friend!

You'll hear me harp on about the magic that is pasta water in 99% of my recipes. It really is a key ingredient in every sauce I make. The starch left behind in the water acts as a thickening agent and helps sauces cling to the pasta. I couldn't make a sauce without it.

I never EVER drain my pasta in a colander, I always transfer it directly to the sauce using a spider strainer. That way the pasta pot full of water is left there for you to ladle in as you need. if you have seen my reels on instagram you'll notice my sauces are SAUCY.

Pasta soaks up liquid so quickly so I add enough pasta water to make it quite liquidy. By the time I serve into bowls and take to the table it hasn't dried up. You'll get to know what the right consistency is with some practice, you can't go wrong though I promise!

What pasta shape is best for this sauce?

It will work with absolutely any shape though, dried or fresh! I have used my homemade orecchiette because if you know me at all you'll know it is my favourite! If you want to make a slight easier shape give my hand rolled gnocchi sardi a try. Both shapes are made with my easy semolina pasta dough.

If you feel like making some fresh egg pasta make sure you use my easy homemade pasta dough, it is completely fool proof.

Recipe FAQs

Do I have to roast the garlic?

If you want the full flavour experience then yes! Roasting garlic makes it so much sweeter and delicious, the extra effort is worth it I promise. If you are really short on time then just use 3 - 4 cloves of garlic finely chopped and add it to the butter with the pepper.

What cream is best for pasta sauces?

Creams are all called slightly different things in different countries. Here in New Zealand, for cooking I use single cream. In America that is light cream. 18% - 30% fat. Anything heavier will be too thick. You can obviously thin down the consistency with pasta water though.

I can't find the paprika flakes, can I substitute?

I get these ones but it's really no drama if you leave them off. A little sprinkle of regular chilli flakes will be just as good, they are spicy though so be sparing if you don't like heat.
