How to make rosemary butter

Rosemary butter is a delicious way to use up homegrown, fresh rosemary at the end of summer.

One of the great things about rosemary butter is its versatility – it can be used as a spread for toast or sandwiches, as a topping for grilled meats or vegetables, or simply as a delicious way to add some extra flavor to a dish.

While you can find rosemary butter already made at many stores, it’s also very easy to make at home, and only requires a few ingredients.

Some other compound butters you might like to try are: tarragon butter and lemon dill butter

Ingredients

Quantities given in recipe card below. 

Unsalted butter

Use regular unsalted butter (note: always use real butter, not margarine). It needs to be room temperature, so remember to get it out of the refrigerator 1-2 hours before making this recipe.

If you don’t have unsalted butter, you can also use salted butter, just omit the additional salt from the recipe. 

Fresh rosemary

Freshly picked, washed, and finely chopped. It is best to use new rosemary growth with softer leaves than the older growth with very hard leaves. 

Finely ground black pepper

This is optional, and can be added to taste. 

Salt

I usually use kosher salt, or other flaked salt as it dissolves so easily in the butter. However, fine sea salt is also a good option.

You want something that will dissolve in the softened butter easily so you don’t end up with crunchy butter. 

Optional garlic

Use one clove of garlic, freshly crushed. Garlic rosemary butter is delicious, but you skip this ingredient if you are not a fan of garlicky butter.  

Directions

Step 1: Pick the leaves from the sprig of rosemary, and chop finely. Crush or finely chop the garlic. 

Step 2: Cut the butter into 6-8 pieces and place it into a mixing bowl. Mash it with a fork until it softens.

Step 3: Gradually add the rosemary, garlic, salt and pepper to the butter, mashing it thoroughly with a fork to ensure that each addition is well mixed with the butter.

Step 4: Once all the ingredients are added and well mixed, transfer the rosemary butter to an air tight container and store in the refrigerator for up to a month. 

Serving

This herb butter is particularly good melting on top of a freshly grilled steak, but here are some other ideas to try: 

  • Spread rosemary butter on a sliced baguette and melt under a hot broiler/grill to make delicious rosemary garlic bread.  
  • Use it for cooking any meat or vegetable dish that needs a hit of flavor. 
  • Add to a hot pan of roasting potatoes for crispy rosemary butter roasted potatoes.

Storage

As with any herbed compound butter, store in an air tight container in the refrigerator for up to a month.

A convenient way to store it is to roll it into a roll of waxed paper with twists at either end. Then use a sharp knife to slice the butter into coins for serving. 

For longer term storage, you can keep this butter in the freezer for up to 6 months. Store in portions in freezer-safe zip lock bags. Remember to label and date them.
