Today’s Roasted Butternut Squash recipe takes a signature side—roasted butternut squash cubes—and transforms it into a dish that’s worthy of a special occasion.

While it may start like any other roasted vegetable recipe—olive oil, salt, and pepper—the additions of brown butter, hazelnuts, and thyme elevate it with festive flair.

Butter in most applications is good (Julia Child can confirm), but brown butter is better. Worlds better.

Cooking the butter until the milk solids brown and become caramelized gives the butter a toasted, nutty flavor and more complexity. A general rule of thumb: the deeper the color, the deeper the flavor.

For this squash recipe, the sultry signature flavor of brown butter gets an aromatic lift from garlic and fresh thyme.

Hazelnuts amplify the nutty goodness, complementing the honey-like sweetness of the squash like a dream.

The Ingredients

Recipe ingredients arranged on a wooden board with labels.
  • Butternut Squash: Butternut squash is brimming with eye-healthy vitamin A, and an excellent source of immune-supporting vitamin C. It also boasts an army of B vitamins plus a decent punch of potassium.
  • Hazelnuts: Hazelnuts add heart-healthy unsaturated fats plus magnesium (an often overlooked mineral that helps manage blood pressure) to the mix. Alternatively, you can use pecans.
  • Butter: I suggest using salted butter here.
  • Thyme: For a woodsy, aromatic lift. Alternatively, you can use fresh or rosemary – whichever you have on hand!
  • Garlic: Optional, however I struggle to find a savory dish not made better by garlic.
  • Pomegranate: For a punch of acidity and brightness, plus some festive flair.

For a complete list of ingredients and quantities, see the recipe card below.

Substitutions and Additions:

  • Use Sweet Potato: This recipe also works beautifully with sweet potato. Simply peel and cut into chunks.
  • Make Nut-Free: If you’re cooking for someone with a nut allergy, you can swap the hazelnuts for pumpkin seeds.
  • Make Dairy-Free: While vegan butter does not brown the same way dairy butter does, you can still melt it for similar effect.
  • Use Different Herbs: The beauty of this recipe is how versatile it is. You can use any woodsy herb you have on hand, such as rosemary or sage.

Step-by-Step Instructions:

Step 1: Roast Butternut Squash

Peel and slice the squash into 1×1-inch cubes. Place on a baking sheet, and toss in olive oil, salt, and pepper. Roast for 35 minutes, tossing once midway through.

Step 2: Prepare Brown Butter Hazelnuts

Meanwhile, melt butter in a small skillet over medium heat. Cook, swirling occasionally, until the foam subsides, the milk solids turn golden-brown and it smells nutty, about 3 minutes.

Stir in hazelnuts, garlic, and thyme and cook 1 more minute. Remove from heat, and season with a pinch of salt.

Recipe FAQ

Is Butternut Squash Healthy?

Butternut squash is rich in vitamins A and C, as well as many B-vitamins and potassium. It’s a nutritious vegetable to support your immunity and eye health.

Why Roast Butternut Squash?

Roasting is the best way to cook butternut squash because it renders it tender, caramelized, and ultra sweet. It’s also super simple, and takes minimal preparation time.

Why is my Butternut Squash Mushy?

The key to avoiding mushy butternut squash is to not overcrowd the pan. If the squash don’t have ample space on the pan, they will steam instead of roast, which inhibits proper caramelization.

How to Store and Reheat Butternut Squash:

  • To Make Ahead. Peel and slice the squash into cubes 1 day ahead. Store cubes in an airtight container in the refrigerator until ready to roast.
  • To Store. Store leftovers in an airtight storage container in the refrigerator for 4 to 5 days.
  • To Reheat: Gently reheat over medium-low heat in a skillet on the stovetop, in a 350ºF oven, or in the microwave until warm. (I prefer the stovetop, personally!)

    I haven’t gotten a reply, and I was wondering if you’ve made this ahead of time and just reheated it, and if so, was it as good—350 for 20 mins?? I had another question about the garlic, wouldn’t it burn if you put it in bubbling hot butter? I’d like to hear your suggestions. Thank you

    Would it be possible to make the brown butter/nuts/garlic mixture ahead of time and just warm up to pour over the roasted squash? Also, wouldn’t the garlic burn if you put it in bubbling hot butter? I’m hoping to make this – would love to hear your suggestions. Thx

    Fixed income and high grocery store prices have taught me to look for and try recipes that pair with whatever I found at the store on a great sale. Today it was acorn squash, The extra bonus, aside from its price of $.99 was that it was cubed 🙂 So home I came to scour this sweet girl’s collection of recipes and voila here is the one with all the other ingredients I had on hand (save the nuts), As a special bonus I had fresh thyme and fresh sage still looking very lively in the herb garden, and also some home grown garlic which for whatever reason was the best ever garlic this year.. End result? Perfecto.

    Could this be modified for a crock pot in order to bring to a pot luck? Or would it be good reheated in the microwave the next day?
