I know butternut squash is a bit of a splurge on carbs for many of my readers, but if you’re someone (like me!) who loves butternut squash and will splurge on it occasionally, I promise this combination of Butternut Squash with Lime and Rosemary is a wow! The hint of lime with a tiny bit of rosemary really works with the flavor of roasted squash seasoned with sea salt and pepper.

I’m a fan of freshly-cut butternut squash instead of buying those packages of squash cubes (and I’ve shared How to Peel and Cut Butternut Squash.) But I realize that’s probably not happening during the holidays, so when we decided to update the photos for this butternut squash we bought one of those packages of cut-up butternut squash from Costco to make this.

And I have to confess, it was still so delicious that Kara and I both swooned over it! Please try this if you’re a fan of butternut squash, whether you cut it up yourself or buy a package of squash cubes!

What is butternut squash?

Butternut Squash is also called Butternut Pumpkin in some parts of the world, and it’s a type of flavorful winter squash that grows on a vine. It’s delicious and versatile, but you can use other winter squash varieties in this recipe as well.

What ingredients do you need for this recipe?

(This is only a list of ingredients; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

• butternut squash cubes
• Olive Oil (affiliate link)
• fresh-squeezed lime juice, I used my fresh-frozen lime juice
• finely-minced fresh rosemary, or you can use Ground Rosemary if needed
• sea salt and fresh-ground black pepper to taste

What Lime Juice did I use for the Butternut Squash with Lime?

I used my fresh-frozen lime juice, and I’m a huge fan of lime, so I wouldn’t mind some lime wedges to squeeze on at the table as well!

What is Rosemary:

Rosemary is woody perennial that’s definitely one of my favorite herbs. It can be grown nearly anywhere (although if it gets really cold, the rosemary doesn’t always winter over in Utah.) Rosemary tastes great in beef stew, with lamb chops, and of course it’s essential in my favorite Rosemary Mustard Grilled Chicken. And rosemary also freezes well if you’re lucky enough to have it in your herb garden!

How high in carbs is the Butternut Squash with Lime and Rosemary?

This recipe has about 20 net carbs per serving, and although butternut squash is a carb splurge for me, I have to have it once in a while when it’s in season!

How to Make Butternut Squash with Lime and Rosemary:

(This is only a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

1. As you can see the package from Costo gave us 5 cups of peeled squash cubes, I am considering one cup to be a serving.
2. I was so excited that I still had fresh rosemary growing in my herb garden, which I washed, dried, stripped off the stems, and finely chopped.
3. Whisk together the olive oil, lime juice, and finely chopped rosemary. (I used my fresh-frozen lime juice.)
4. Put squash cubes into a bowl and toss with the olive oil, lime, rosemary mixture.
5. Arrange squash in a single layer on the roasting pan and roast at 400F/200C. 
6. We checked it a few times, but it took 50 minutes before we thought it was done, and if you like your squash super soft you might want a few minutes more.
7. Season with salt and fresh ground black pepper and serve hot.

Butternut Squash with Lime and Rosemary

Prep Time 10 minutes

Cook Time 50 minutes

Total Time 1 hour

This Butternut Squash with Lime and Rosemary is an absolute wow for a holiday side dish, and the holidays are busy so we used those pre-cut cubes of butternut squash to make it easy!

Ingredients

• 5 cups butternut squash cubes (see notes)
• 2 T olive oil
• 2 T fresh-squeezed lime juice (see notes)
• 1 T finely-minced fresh rosemary
• sea salt and fresh-ground black pepper to taste

Instructions

1. Preheat oven to 400F/200C.
2. Spray a large baking sheet with olive oil or non-stick spray.
3. If you're starting with a whole squash, follow directions for How to Peel and Cut Up a Butternut Squash.
4. Rinse rosemary if needed, dry with paper towels, strips leaves off stems, and finely mince enough to make one tablespoon.
5. Whisk together olive oil, lime juice, and fresh rosemary.
6. Put squash into plastic mixing bowl, add the olive oil mixture and toss well so squash is all coated with oil.
7. Arrange squash in a single layer on the roasting pan and roast at 400F/200C.
8. We checked it a few times, but it took 50 minutes before we thought it was done, and if you like your squash super soft you might want a few minutes more.
9. Season with sea salt and fresh ground black pepper and serve hot.

Notes

Our squash cubes weighed about two pounds, so if you're using a whole squash you'll need one that's about 2.5 pounds with the skin and seeds.

I used my fresh-frozen lime juice.

This recipe adapted slightly from one found in Bon Appetit, November 2007.
