Equipment

  • Kitchen scales
  • Oven tray
  • Chopping board and knife
  • Bowl
  • Fork
  • Spatula
  • Greaseproof paper, plastic wrap/foil

Ingredients
  

  • 4 cloves garlic
  • 1 tsp olive oil
  • 250 g unsalted butter
  • 2 tbsp rosemary
  • 1 tsp salt
  • ½ tsp pepper
  • 2 tsp lemon juice
  • 2 tsp agave

Instructions
 

  • Leave the butter out to come to room temperature and soften. Softened butter is essential and makes the process much easier and more successful.
  • Preheat the oven to 200 degrees C.
  • Cut the top off a whole garlic bulb - just enough to expose the cloves inside. Remove all the unusable papery layers.
  • Put the bulb of garlic in some foil, cut side upwards, and spoon over the olive oil. Wrap up the foil. Put this in the oven, on a tray or in an oven-proof dish to roast for 30-40 minutes. Once roasted, remove from the oven and set aside to cool.
  • Gather the rest of the ingredients.
  • Wash a couple of sprigs of fresh rosemary and shake off any excess water.
  • Use the tines of a fork to strip the rosemary from the woody stalk, and roughly chop to make around 2 tablespoons in amount.
  • Once the garlic is cool, squeeze out 4 cloves of the roasted garlic and add to the food chopper.
    Add the rosemary to the garlic and chop together until fine, but not completely pureed. You can of course just chop this finely with a knife, if you prefer.
  • In the bowl, either mash the softened butter or whip it to a smooth creamy consistency with a hand mixer or standing mixer.
  • Add the minced garlic and rosemary, salt, pepper, lemon juice and agave nectar and mix.
    Ensure that all the ingredients have been well distributed through the butter.
  • Line a piece of waxed paper onto a baking tray with edges and transfer the compound butter onto it in one even layer, shaping it into a log shape if desired. (You can also make it up into individual portions or shapes - I have used chocolate silicone moulds quite successfully like this.)
  • Roll up the wax paper around the compound butter log, wrapping it tightly like a gift, and pressing down so that all air bubbles are removed from inside the parchment paper; this will help ensure an even freezing surface once your compound butter goes into storage in the freezer later on.
    You can keep some in the fridge - leave for 2-3 hours to firm up and make slicing it easier.
    Place your compound butter log wrapped in parchment paper into an airtight container or zip-lock bag before storing it in the freezer for up to 6 months.
    When you are ready to use it let it thaw in the fridge so that you can slice it. When in the fridge, use it within 4 weeks.

Notes

 

TIPS for making garlic rosemary compound butter

 
1. Choose a good-quality butter, preferably a grass-fed butter for the best flavour and health benefits. Make sure that it is unsalted so that you can have the option of how much or how little salt you want/need to add to the herb butter.
Make sure that you let the butter soften well at room temperature before mixing as this makes the process easier and more successful.
2. While you can use raw minced garlic for this recipe, I find that roasted garlic removed the potential harshness of raw garlic and adds a deeper sweeter garlic flavour.
Finely mince fresh rosemary leaves and roasted garlic cloves to get the most flavour into the compound butter and to ensure that it is in a form that can distribute easily and evenly through the creamy whipped butter.
3. Use equal parts rosemary and garlic to achieve the perfect balance of flavours in your finished product. But you may also want to vary the proportions of rosemary to garlic depending on your preferences.
While I feel that fresh is best, you can also use dried rosemary instead of fresh rosemary in this recipe. Just substitute 2 teaspoons of dried rosemary for the 2 tablespoons of fresh rosemary.
4. The acidic note of the lemon juice and the hint of sweetness from the agave enhance the other flavours and balance them well. You can omit these if you prefer.
I have, on occasion, also added a splash or two of Worcestershire sauce for a deeper umami taste note.
5. Keep the leftover roasted garlic in a container in the fridge and use it in other cooking like pasta, sauces, salads and stir-fries.
Or use all the roasted garlic to make a big batch of garlic compound butter, maybe with different herbs, to store in convenient sizes in the freezer to be available to elevate your dishes with ease.
 

Getting creative with rosemary garlic compound butter

 

Mixing in different herbs

You can add other herbs such as parsley, oregano or sage to the butter mixture for a unique mixed-herb flavour combo.

Adding spices

For some heat, try adding chilli powder/flakes, paprika or cayenne pepper to the butter.

Use roasted or raw garlic

Use roasted garlic for a more mellow flavour and raw garlic for more of a punchy taste.

Adjusting quantities of ingredients

Experiment with using less rosemary or different amounts until you find your perfect level of garlicky goodness!

Browning the butter before mixing it with other ingredients

Yes, this will add an extra step to the recipe, but it can deliver surprising results.
You will need to add the butter to a pan and let it melt over medium heat. Keep moving the butter, then just as it starts to turn brown remove it from the heat. Let this cool at room temperature and maybe even for a brief time in the fridge until it can be whipped up into a creamy consistency. (you could also stand a bowl in another bowl filled with ice cubes and whip the butter until the desired consistency is achieved.
This brown butter improves its flavour by giving it nutty and caramelized notes that will make your compound butter stand out even more!

Infusing flavours like lemon zest into the mix

This gives an extra citrusy note that pairs nicely with rosemary and garlic’s earthiness and brings a freshness to the finished product.
