Why this recipe works

  • Quick & easy to make – this whipped lemon butter comes together in just 5 minutes without any chopping.
  • Whipping butter is so amazing as it makes it easily spreadable and hence perfect to serve alongside bread instead of regular butter.
  • Perfectly balanced taste with the acidity of the lemon balancing the heaviness of the butter – not to mention the crisp saltiness from the sea salt flakes…

Pro tips for making Whipped Lemon Butter

  • Use a food processor, blender or mixer – they all work great for this recipe.
  • If using a regular mixer – just know that it will splatter a bit. So do your mixing somewhere suitable, like in the sink.
  • Always use real lemon juice.
  • Is your whipped butter too thin? Add more solid butter.
  • Is your whipped butter too thick? Add a dash of water.
  • No need to use unsalted butter unless that’s what you have – taste test instead and add just as much salt as you like.
  • Taste test and season to your liking – add more or less salt, lemon or other seasonings as needed.

What to use Whipped Lemon Butter for

  • Serve alongside artichokes for a perfect summer night snack or appetizer.
  • Use instead of regular butter for corn on the cob
  • … or do the same for baked potatoes.
  • Serve on top of your favorite steamed or grilled veggies – broccoli and asparagus love it!
  • It’s the perfect sauce for fish (I love it with fatty fishes like salmon, but it goes amazing with lighter white fish as well!).
  • Seafood in general (did I hear lobster and crab?? not to mention some barbecue shrimp or prawns… or on top of scallops… now I’m hungry!!).
  • Place a good amount on top of a freshly grilled steak and watch it melt and season at the same time.
  • Not to forget – bread. Use instead of regular butter and you won’t need any other topping. This is 100% how I use the leftovers, every single time…

How to make Whipped Butter

How about that? No chopping in this recipe – at all! All you need to do for prep is melt a third of your butter and cut the other two thirds in small-ish cubes, and squeeze your lemon. That’s it! Now let’s get started cooking.

Start by bringing out a food processor, mixer or blender. You really need one of them, but which one you choose is entirely up to you. I like using my food processor as this ensures the splatter stays inside.

Then first pour in your melted butter and add in a few of the solid butter cubes. And start mixing!

With the food processor or whatever you’re using running, add in a few solid chunks of butter at a time, until you’ve added them all. Then add in some lemon juice and salt. I recommend starting with half first, and then taste testing and adding more as needed.

Now if you’re using a food processor or blender it might need a little bit of help – especially if you’re making a smaller batch of whipped butter. So when it looks mixed and nice, stop the engine, mix well with a spoon and taste test. Add more seasoning if needed and then start it up once more. Mix a short while and then you’re done!

Other ways to season your Whipped Butter

Whipped butter is such an amazing invention, and even though I most often make this lemony kind there are all kinds of ways you could season it. Why not try it with

  • herbs (dill, basil, rosemary… match the seasoning of your food for a real flavor bomb!)
  • garlic for a true classic
  • capers, or for an extra special treat
  • browned butter instead of just melted butter.

How long will whipped butter keep?

Whipped butter will keep for up to 5 days in the fridge, however it will lose its smooth consistency when refrigerating and revert to the regular hard butter texture. This doesn’t have to be a bad thing though – all the flavor is still there and I highly recommend you still refrigerate any leftovers and just top anything you can think of with it! If you want it a bit softer again for serving, just bring it out ahead of time.

Now over to you – make this recipe your own with the amount and type of seasoning that best suits your tastebuds! Did you find any amazing seasoning I’ve missed in my list of suggested seasonings?
