Ingredients and Tools

  • Unsalted butter — this is a must for a butter sauce, and there is no replacement. You may use salted butter if that’s all that you have at home.
  • Brazilian sofrito — or a few garlic cloves, minced.
  • Lime — we will be using both the lime zest and lime juice.
  • Parsley — fresh parsley that’s been freshly minced adds beautiful color and flavor to our sauce! You simply will not get the same result with dried parsley.
  • Salt and pepper — you’ll add these to taste at the end. Medium grain kosher salt (like Diamond Crystal) and freshly ground pepper are my favorite.

How to make Lime Butter Sauce

Melt half the butter in a small skillet or saucepan over medium-low heat.

Add the brazilian sofrito to the melted butter and sautee until fragrant and golden.

As this happens, the butter will also brown a little and along with the golden garlic and the fatty butter, will provide a perfectly nutty sweet flavor.

Then just add in the lime juice. This will cut through the fat and will also provide a pop of brightness to the sauce.

Add in the rest of the butter, just to melt and turn off the heat.

Whisk in the parsley and the lemon zest at the end, and then you’re done!

Pro Tip

It’s important to add these two ingredients off the heat because we don’t want to cook them. We just need the residual heat to warm them up and release their bright, grassy green flavor oils into the sauce.

If we cook them, the flavor profile changes and the lime zest can turn bitter and the parsley become muted and flat.

Give it a taste and add salt and pepper to taste, if needed.

How to store:

You can double the recipe and save more for later.

And if you have any leftovers, store it in an airtight container and keep in the refrigerator for up to a week or so. To reheat, pop it in the microwave and heat it in short bursts at a time – give it a stir to combine everything as the butter melts.

How to serve:

I photographed this recipe while I was working in Brazil, so I served it with purê de batata baroa (also known as purê de mandioquinha, depending on where you are in Brazil).

This root vegetable is one of my obsessions and when I’m in Brazil, I typically eat it with every meal. It’s so good!!

Sadly, I haven’t be able to find it anywhere I’ve been outside of Brazil.

If you want to serve this alongside a starchy carb, try it out with Mashed Yuca, Fried Sweet Plantains or Instant Pot Garlic Mashed Potatoes.

This sauce is delicious drizzled on Air Fryer Broccolini and Baked Asparagus with Parmesan.

You could also serve it with rices, like Instant Pot Brown Rice Recipe, Carrot Rice and Walnut Rice.
