Who can resist sweet roasted butternut squash with crispy edges and a tender, creamy center?!
But today's recipe from one of my favorite cookbooks Dinner in French by Melissa Clark, takes your basic butternut squash a few notches up with just some simple additions...
Here, the perfectly caramelized thin slices of butternut squash are topped with a bright lime vinaigrette (with red pepper flakes) to bring out the sweetness of the squash with their contrasting pungency + a sprinkle of chopped, nutty hazelnut for crunch!
Do you have to peel butternut squash before roasting?
While butternut squash skin is edible and it can even turn nice and crisp when roasted, many people prefer to peel it first so it's easier to eat.
Butternut squash skin is smooth and thin and the best way to peel it is by using a sharp vegetable peeler. It really is that simple!
How to prepare and peel butternut squash for roasting?
To prepare for this roasted butternut squash recipe, here is what you do:
- Peel the butternut squash. First, trim the sides using a good chef's knife (this will help you steady the butternut squash on one of the cut flat sides). Stand the butternut squash on one of the trimmed sides on your cutting board and use a sharp vegetable peeler to peel working downwards (peel off long strips).
- Cut the butternut squash in half. Stand the squash on one of the cut, flat sides. Carefully cut down the middle using your sharp chef's knife.
- Seed the butternut squash. Take a spoon and scoop out the seeds; you should have an empty cavity in each half of the squash. The seeds are edible and can be cleaned and toasted separately, if you like.
- Cut each butternut squash half into thin slices. Turn a butternut squash half on it's belly (the side with the empty cavity), take your chef's knife and slice it into ½ inch thick slices. Do the same with the other half.
Now you're ready to make this epic pan roasted butternut squash recipe!
How to roast butternut squash: step-by-step
You're looking for perfectly tender, and even slightly charred roasted butternut squash. Set your oven on high heat at 425 degrees F and reach for a large baking sheet or two. Thinly-sliced squash will take about 30 to 35 minutes to roast in a high-heated oven. Here is how (print-friend recipe below):
- Set the oven on high heat at 425 degrees F. Arrange a rack in the middle
- Arrange the butternut squash slices in one single layer on a lightly oiled baking sheet or two. It's important not to crowd the squash so each slice cooks properly and you can even get some nice caramelization.
- Brush the top of the squash slices with good extra virgin olive oil. Season with kosher salt and black pepper
- Bake in the heated oven for 20 minutes or so, then turn the squash slices over and return to the oven for another 10 minutes or until tender and browned in some parts (if you need more color still, stick the baking sheet under the broiler briefly and watch carefully).
Add flavor & finishing touches!
Now, what really puts a special spin on your basic butternut squash recipe are Melissa's finishing touches: lime vinaigrette, chopped hazelnuts (walnuts or pecans will work too), and a handful of chopped scallions.
I like adding the lime vinaigrette to the butternut squash while still hot, then follow with the chopped nuts and scallions.

Roasted Butternut Squash Recipe
- 3 tbsp extra virgin olive oil
- 1 Butternut squash (2 lbs.), peeled, halved, and seeded
- ¼ tsp Kosher salt, (or fine sea salt)
- 2 tbsp fresh lime juice
- ½ tsp finely grated lime zest
- 1 garlic clove, minced
- Crushed red pepper flakes, a pinch
- ¼ cup chopped toasted hazelnuts, (or walnuts or pecans)
- 3 oil-packed anchovy fillets, minced
- 2 scallions (whites and green parts), thinly sliced
- Heat the oven to 425 degrees F.
- Oil a rimmed baking sheet and arrange the squash slices on it in a single layer. (If it doesn't all fit, oil another sheet and use that as well.) Brush the top of the squash slices with more extra virgin olive oil and sprinkle them with the salt and black pepper to taste.
- Roast in the heated oven until the squash is golden brown on the top, 20 minutes. Then flip the slices over and roast until they are very tender, about 10 minutes longer. (I ended up putting mine under the broiler for a couple more minutes for a little more color).
- Meanwhile, make the vinaigrette. In a small bowl, combine the lime juice, zest, garlic, red pepper flakes, and a pinch of salt. Let the ingredients sit for a minute, then whisk in the anchovies and 3 tablespoons extra virgin olive oil until emulsified. Taste and add more salt and/or lime juice as needed.
- Serve the squash covered with the vinaigrette and sprinkled with the hazelnuts and scallions.
