Garlic bread: the butter ratio, and every way to cook it

Fifty grams of softened butter to two fat cloves of garlic, crushed to a paste with salt, plus a handful of parsley. That ratio is the whole recipe. Everything else is which bread you start from and how you apply the heat.

Garlic bread goes wrong in two predictable ways: the garlic burns and turns acrid, or the bread dries to a rusk before the butter has soaked in. Both are solved by the same two things, crushing the garlic rather than chopping it, and keeping the heat moderate.

The garlic butter

Enough for one baguette, which serves four.

The one technique that matters. Put the peeled cloves on a board, sprinkle over the salt, and crush and drag them with the flat of a knife until they become a smooth paste. The salt is an abrasive and does the work.

This is not fussiness. Chopped garlic leaves pieces standing proud of the butter, and those pieces are in direct contact with the oven heat. Garlic scorches at a much lower temperature than bread browns, so those pieces blacken and turn bitter while everything around them is still pale. A paste disappears into the butter and cannot burn on its own.

Which bread

Method one: the oven, for a whole loaf

The standard, and the best for a baguette.

1. Heat the oven to 200C fan. Not hotter. Above about 210C the butter smokes before the middle is hot.
2. Cut the loaf. Either split it lengthways for maximum surface, or make diagonal cuts about three quarters of the way through at 3 cm intervals, which keeps it in one piece and is better for sharing.
3. Work the butter into every cut surface, right to the ends. Use your fingers; a knife cannot reach into a slashed loaf.
4. Wrap in foil for the first 10 minutes, then open the foil for the last 5. The wrapped phase steams the crumb soft and lets the butter penetrate; the open phase crisps the top. Skipping the wrap is why shop-style garlic bread often has a hard crust and a dry middle.
5. 15 minutes total. Serve within a couple of minutes.

Method two: the sliced-bread version, in five minutes

The one most people actually make on a weeknight, and it is genuinely good.

1. Toast the slices first, on a medium setting. Firm, dry, barely golden. This is the step that keeps the base crisp under the butter rather than soggy.
2. Spread the garlic butter on the hot toast, so it melts straight in instead of sitting on top.
3. Grill for two to three minutes on a middle shelf until the surface bubbles and colours.

Thick-cut bread and sourdough both need a toaster that will actually take the slice, which is the thing most people never check before buying. We measured which loaves fit in the artisan bread test, and it is why every Toastley toaster is built around a wide slot rather than a standard one.

Never put buttered bread into a toaster. The butter melts, runs down onto the element, smokes and can catch fire, and it is close to impossible to clean out afterwards. The toaster is for the plain slice, before anything goes on it.

Method three: the air fryer

Fast and very effective, because circulating air crisps the surface without drying the middle.

180C for 5 to 7 minutes for buttered slices or a split baguette cut to fit, in a single layer with space around each piece. No preheating needed. Check at 4 minutes the first time, because air fryers vary more than ovens do.

Do not stack the pieces. Overlapping slices steam each other instead of crisping, which is the same principle that governs toasting bread in an air fryer.

Method four: the frying pan

Best for thick sourdough slices, and it gives a fried crust an oven cannot match. Butter both faces, lay into a dry medium-hot pan, three minutes a side. Keep the heat moderate: garlic butter scorches at a temperature plain butter tolerates.

Cheesy garlic bread

Add 80 g of grated cheese per baguette, half mozzarella for melt and half mature cheddar for flavour. Two rules:

• Cheese goes on for the last 5 minutes only. Added at the start it dries out and goes leathery long before the bread is ready.
• Butter first, cheese on top of the butter. Cheese directly on bread forms a waterproof layer and the garlic butter never soaks in.

Block mozzarella, not the fresh kind packed in water, which floods the bread. The same logic applies to pizza toast.

Making it ahead and freezing it

Garlic bread freezes better than almost anything else in this blog.

• Butter the raw loaf, wrap it tightly in foil, and freeze. It keeps three months.
• Cook from frozen at 200C fan, foil on, for 20 to 25 minutes, opening the foil for the last 5. Do not defrost first; a defrosted buttered loaf goes soggy.
• The butter alone freezes too. Roll it in greaseproof paper into a log and slice off discs as needed. This is the version worth keeping permanently in the freezer.
• In the fridge, buttered uncooked bread keeps two days wrapped.

Cooked garlic bread does not keep well. It goes tough within hours and reheating dries it further. Make what you will eat.

What to serve it with

• Pasta and anything tomato based. The obvious one, and the bread is there to clear the plate.
• Soup. Better than a bread roll, particularly with something thick and vegetable based.
• A roast chicken. Under the bird for the last 10 minutes, to catch the juices.
• On its own, with a drink. The most honest answer.

Six things that go wrong

• Chopped garlic instead of crushed. The pieces burn and turn bitter. Crush it to a paste with salt.
• Melted butter. It runs off and pools. Soften it to room temperature instead.
• Oven too hot. Above 210C the butter smokes and the crust hardens before the middle warms.
• No foil phase. The loaf dries out. Wrap for two thirds of the cooking, open for the last third.
• Cheese on too early. It goes leathery. Last five minutes only.
• Not enough butter. This is not a dish that rewards restraint. 50 g per baguette is the floor, not the ceiling.

Common questions

What is the ratio of butter to garlic for garlic bread?
Around 50 g of softened butter to two large cloves of garlic, with two tablespoons of chopped parsley and a quarter teaspoon of salt. That is enough for one baguette, serving four.

How long does garlic bread take in the oven?
15 minutes at 200C fan: 10 minutes wrapped in foil, then 5 minutes with the foil opened so the top crisps. From frozen, 20 to 25 minutes with the same final 5 minutes open.

Can you make garlic bread in an air fryer?
Yes, and it works well. 180C for 5 to 7 minutes in a single layer with space around each piece, no preheating. Check at 4 minutes the first time, as air fryers vary.

Can you make garlic bread in a toaster?
Not with the butter on. Butter melting onto the heating element is a fire risk and very hard to clean out. Toast the plain slice first, then spread the garlic butter on while it is hot and finish it under the grill.

Why does my garlic bread taste bitter?
The garlic burnt. Chopped garlic leaves pieces sitting proud of the butter where they scorch, because garlic burns at a much lower temperature than bread browns. Crush the garlic to a paste with salt so it disappears into the butter.

Can you freeze garlic bread?
Yes, and it is the best way to make it ahead. Butter the raw loaf, wrap tightly in foil and freeze for up to three months, then cook from frozen without defrosting.

What bread is best for garlic bread?
A baguette for the classic version, or ciabatta for a more open crumb that soaks up more butter. Thick-cut sourdough works well in a pan, and sliced white bloomer is the quickest weeknight route.
