Given it’s indulgent flavor, it’s not surprising to see plenty of decadent recipes with brown butter, such as Browned Butter Snickerdoodles or Browned Butter Brownies from The Food Charlatan. Even breakfast gets the brown butter treatment, like these Banana Nut Chocolate Chip Muffins.

So if it makes these goodies even better, then it must do the same to the healthy stuff, right?

Yes! Browned butter adds a savory nuttiness and complexity to any dish, like Cauliflower Rice, Buttery Peas and Carrots, and this dish!

And the great thing about it – if you use the real, full fat stuff and brown it all up, it is so packed with flavor that you only need a smidge to have a huge impact.

For a good size butternut squash, I only used two tablespoons of butter, and it made quite a lot. The four of us ate it, with plenty of leftovers.

Brown Butter Mashed Butternut Squash Recipe

The addition of the browned butter makes this mashed butternut squash so luxurious, with a lovely, velvety texture, and rich, well-developed flavor. Everyone will enjoy simple, nutritious, but impressive side dish.

How do you make mashed butternut squash?

  1. The first step is to peel and cut the butternut squash into 1-inch pieces. Be sure to use a very sharp knife and cut the squash carefully.
  2. Steam the squash in a steamer basket over a simmering pot of water.

    Note: some people then like to use roasted butternut squash when they mash it in order to get some additional flavor. But simple steaming lets the nutty butter flavor shine in this recipe.
  3. While it steams, brown your butter, then add the sage. It will foam slightly when you do this.
  4. Add the squash, browned butter mixture, and salt and pepper to a blender or food processor and puree until smooth. You can also use a hand blender.
  5. Return the mixture to a pot and heat through, evaporating off any excess moisture to achieve your desired thickness.

How do you brown butter?

You can see step-by-step photos for how to brown butter from Country Cleaver.

In short, heat a pan over medium-low heat. Add the butter, let it melt and start to foam. Stir frequently until the butter becomes golden in color and some brown bits start to collect at the bottom. Be careful not to burn the butter.

How do you make this recipe Whole 30 compliant?

That’s simple. You just need ghee, which you can buy, or you can make homemade ghee, as you can see from Foodie With Family.

Basically, the process of making brown butter and ghee is the same. With ghee you are cooking it long enough to separate the butterfat from the milk solids and then removing the solids. When making brown butter, you just cook it longer to develop that nutty, toasty flavor, and you might not necessarily separate it from the solids unless you choose to based on your particular diet or preferences.

So to make a paleo or Whole 30 compliant version of Brown Butter Mashed Butternut Squash, after browning the butter pour it through a fine mesh sieve lined with cheesecloth to separate the milk solids from the browned ghee.

    I adore this recipe, Brianne! All the satisfaction of a creamy, luscious, indulgent dish and none of the guilt (even if I eat the entire thing in one sitting…that won’t be frowned upon, right?). I love butternut squash. I’ve really got to cook with it more this year.
