Ingredients You’ll Need
What I love about this recipe is how few ingredients it calls for, yet each one is essential to achieving the perfect Pesto Butter (Compound Butter). The beauty is in the balance—herbs, nuts, cheese and olive oil blend together to create a pesto that transforms plain butter into something magical.
- Unsalted Butter: Start with high-quality butter, softened, so it easily combines with your pesto and delivers the creaminess you crave.
- Basil Leaves: The fresh, sweet, and peppery punch of basil is what makes this compound butter sing with summer flavor.
- Garlic: Just two cloves infuse that classic pesto aroma you know and love—feel free to use more if you want an extra kick!
- Parmesan Cheese: Freshly grated makes all the difference, adding umami and a touch of saltiness to the butter blend.
- Pine Nuts (optional): They provide a background nuttiness and richer texture, but if you skip them, your Pesto Butter (Compound Butter) will still be wonderfully smooth.
- Olive Oil: Silky olive oil binds the pesto ingredients together and rounds out the butter, helping everything blend beautifully.
- Lemon Zest & Juice (optional but recommended): Just a bit of zest and juice brighten all the flavors and bring out the freshness.
- Kosher Salt: Don’t skimp! Salt is key for making the flavors pop, so taste as you go and adjust to your liking.
- Freshly Ground Black Pepper: A crack or two brings a gentle heat and complexity to the whole spread.
How to Make Pesto Butter (Compound Butter)
Step 1: Make the Pesto
In your food processor, add those aromatic basil leaves, garlic cloves, Parmesan cheese, and optional pine nuts. Pulse several times, pausing to scrape down the sides as needed, until the basil is chopped super fine. You want everything well integrated while keeping just a hint of texture—think of it as the polished, green-packed foundation of your Pesto Butter (Compound Butter).
Step 2: Finish the Pesto
Now, pour in your olive oil along with the lemon zest, lemon juice, a sprinkle of salt, and a few grinds of black pepper. Process the mixture until it reaches a gorgeous, creamy consistency just the way you like it—silky smooth or ever-so-slightly coarse. Taste and fiddle! Add a little more olive oil if it looks too thick, or punch it up with another dash of lemon or salt to perfect the balance.
Step 3: Make the Compound Butter
In a medium bowl, combine the softened butter and a generous 2-3 tablespoons of your fresh pesto. With a fork (or a handheld mixer if you’re feeling fancy), mash and blend until the pesto is fully incorporated and no streaks of butter remain. It will take on this stunning green marbled glow! Taste for seasoning—add another pinch of salt or an extra spoonful of pesto if you want even bolder flavor.
Step 4: Serve or Store
You can use your Pesto Butter (Compound Butter) right away, or scoop it into a jar or wrap it in parchment to stash in the fridge. It firms up as it chills, perfect for slicing over grilled veggies, steak, or spreading on warm bread throughout the week.
