Roasted Garlic Butter Recipe for Homemade Bread, Steak & Veggies

We fell for this versatile roasted garlic compound butter — it’s become a fridge staple we can’t live without. ❤️

Bold and aromatic, it lifts almost any dish. Spread it on warm bread for irresistible garlic bread, melt it over a hot steak, toss it with pasta for a quick creamy sauce, or stir it into vegetables for extra depth. A spoonful on a baked potato is heavenly.

What magic occurs when you roast garlic?

Roasting transforms garlic: it softens the cloves, tames the sharp bite and brings out a mellow, sweet, nutty character. Slow roasting caramelises the natural sugars and concentrates flavor, turning harsh raw garlic into a creamy, spreadable ingredient with deep roasted notes. The result is a butter that’s both sweet and savory with a rich garlic essence.

It’s a simple technique with big rewards — you’ll find yourself adding it to everything.

Key ingredient notes and substitutions

See the recipe card below for exact quantities.

Garlic

Use about 150g of whole, unpeeled garlic heads (not loose cloves). Roasting mellows and concentrates the flavour, so you need a generous amount of heads to get a pronounced roasted garlic taste.

Olive oil

Olive oil coats the garlic before roasting and helps caramelise the cloves. Vegetable oil can be substituted if preferred.

Butter

Salted butter gives the fullest flavour, but unsalted works if you add flaky sea salt to taste. Use butter at room temperature so it blends smoothly.

Herbs

The recipe uses parsley and rosemary, but you can swap or add thyme, basil, oregano, coriander, chives or mint depending on the dish. Lemon zest is a bright addition, and fresh herbs make the butter pop — experiment freely.

Instructions: Step-by-step

• Preheat the oven to 180°C / 356°F (gas mark 4). Line a baking sheet with foil for easy cleanup.
• Slice the very top off each garlic head to expose the cloves — this helps oil and heat penetrate and makes it easy to squeeze the roasted garlic out later.

• Place each head on a square of foil (about 20cm x 20cm). Drizzle roughly one teaspoon of olive oil over the cut top of each head, then wrap the foil into a sealed parcel and arrange on the baking sheet.

• Roast for about 45 minutes, until the cloves are soft and lightly caramelised. If needed, unwrap one parcel and return to the oven for another 5 minutes.
• Let the garlic cool for 15 minutes, then squeeze the soft cloves from their skins into a bowl.

• Combine softened butter, chopped fresh herbs and a few grinds of black pepper in a food processor and blend until smooth.
• Add the roasted garlic and pulse until the cloves are evenly distributed. Taste and adjust seasoning if needed.
• Transfer the mixture to cling film, shape into a tight log, wrap, and chill in the fridge until firm.

Serving suggestions

• Pipe butter rosettes with a piping bag instead of rolling a log for an elegant presentation.
• Wrap in baking paper and tie with butcher’s string for a rustic look when serving at the table.
• Slice into rounds to serve individual portions or keep in an airtight container in the fridge for cooking and finishing dishes.

Uses

• Melt over fillet, ribeye, sirloin or rump steaks.
• Toss with sautéed mushrooms or steamed green vegetables.
• Spoon over fish, pork chops, prime rib, roast chicken or turkey.
• Stir into pasta, use on baked potatoes, or spread on fresh crusty bread for garlic bread.
• Add to roasted or steamed vegetables, crackers, or use to fry onions for extra flavour.

Variations

Try these swaps to change the flavour profile:

• Herbs: mint, coriander, basil, thyme, chives, tarragon.
• Spice: red pepper flakes, smoked paprika, chipotle or harissa.
• Veg add-ins: sun-dried tomatoes, roasted peppers, caramelised shallots or crispy onions.
• Citrus: lemon or orange zest for brightness.
• Nuts & cheese: chopped toasted nuts, Parmesan or blue cheese for richness.

Storage

Keep tightly wrapped compound butter in the fridge for up to one month. For longer storage, freeze for up to three months and thaw overnight in the refrigerator before using.

What exactly is compound butter?

Compound butter is simply butter mixed with additional flavourings — herbs, spices, aromatics or other ingredients — and then reformed and chilled. It’s used to finish meats and vegetables, spread on bread, or melt into sauces to add concentrated flavour.
