You know what’s better than fresh homemade butter?
Leek butter.
This came together so quickly, and the flavor is honestly incredible. It’s rich, creamy, and has just enough savory depth from the leeks to make it feel a little elevated — without being complicated at all.
We did a full taste test, and it was an immediate hit…
well, for most of us 😅
We couldn’t convince Gemma and Trace to try it, but everyone else loved it — and Ben said it was one of my finer creations, so I feel like that says everything you need to know.
Why You’ll Love This
This is one of those recipes that looks impressive but is actually incredibly simple.
- Comes together in about 20 minutes
- Uses just a few ingredients
- Great way to use seasonal leeks
- Turns basic butter into something really special
If you’ve never made butter before, this is a great place to start. And if you have, this is a fun way to take it up a notch.
What Is Leek Butter?
Leek butter is a compound butter, which just means butter that’s been mixed with additional ingredients for flavor.
In this case:
- Fresh homemade butter
- Sautéed leeks
- Lemon juice
- A little salt
Leeks are part of the onion family, but much milder and slightly sweet when cooked. They add flavor without overpowering the butter, which makes this super versatile.
How It Comes Together
The process is actually really simple:
- Whip heavy cream until it turns into butter
- Separate and rinse the butter to remove buttermilk
- Sauté your leeks until soft and fragrant
- Mix everything together with a little lemon and salt
That’s it.
It happens fast — and if you’re doing it in a mixer, don’t walk away… it goes from whipped cream to butter (and a bit of chaos 😅) pretty quickly.
Don’t Skip the Ice Bath
Once your butter forms, you’ll want to rinse it in ice water.
This step:
- Removes leftover buttermilk
- Helps the butter last longer
- Improves the texture
It only takes a minute, but it makes a big difference.
How to Use Leek Butter
This is one of those things that instantly makes everything taste better.
Try it on:
- Fresh sourdough or toast
- Eggs
- Roasted vegetables
- Steak or chicken
- Warm bread straight out of the oven
Honestly, even just spreading it on a piece of bread is enough.
Storage
- Store in the fridge for up to 1 week
- You can also freeze it in smaller portions
If you’re making a batch, it’s worth shaping or portioning it so you can grab what you need later.
Final Thoughts
This is one of those recipes that feels a little fancy, but is actually really practical.
It came together quickly, tasted amazing, and is definitely something we’ll be making again — especially while leeks are in season.
And if you’ve got a couple hesitant taste testers in your house… you’re not alone 😅
