Why We Love Whole Roasted Butternut Squash

- Easy: No peeling, no chopping, only 3 ingredients needed
- Cozy fall flavors: Roasted squash is the perfect fall side dish for weeknights and holiday dinners
Ingredients and Easy Swaps
- Butternut squash: Look for butternut squash that is heavy for its size. It should be light orange-beige in color without any soft spots. It’s normal for it to have some imperfections or scratches. This recipe and glaze would also work for acorn squash, delicata squash, or honey nut squash. Just adjust the baking time.
- Olive oil: In order to get brown and caramelized, the squash needs to be coated with some kind of fat. Olive oil is the most common but you could also use melted butter, coconut oil, avocado oil, or another oil of your choice.
- Salt and pepper: To bring out the natural flavors of the squash, kosher or sea salt is a must. Black pepper is a nice contrast to the sweetness of the butternut squash.
- Optional glaze: For holiday meals, we always make a sweeter roasted squash with a glaze made of butter, brown sugar, and cinnamon. Flip the squash over during the last ten minutes of cooking and add the glaze.
- Roasting time: Keep in mind that roasting time can vary depending on the size of the squash. Start checking the squash at the 45-minute mark but know that large squash can take around 75 minutes.
- Wrapping in foil: Some people wrap the squash halves in foil when roasting. This will actually steam the squash. Only wrap the butternut squash in foil if you do not want any browning or caramelization. Even if I am using the squash in soup or mashed, I still like the extra flavor it gets from roasting it on a baking sheet.
- Save the seeds: Butternut squash seeds can be roasted just like pumpkin seeds. Wash and dry the seeds. Toss with oil and seasoning. Then roast at 350 degrees for 10-13 minutes. Use it for snacks, salad toppers, or with oatmeal.
Think of this recipe as a blueprint for making perfectly roasted butternut squash halves. Then you can season it any way you like. Here are some favorites:
- Herbs: Fresh herbs pair really well with butternut squash. Add fresh parsley, thyme, rosemary, sage, or oregano.
- Spices and seasoning: The sweet flavor of the squash works really well with smoky and earthy spices like cumin, curry powder, coriander, cinnamon, smoked paprika, or chili powder. It also works with warm spices like cinnamon, ground ginger, and allspice.
- Garnishes: When I am serving this for holidays, I love to get creative by adding garnishes including toasted pumpkin seeds, creamy goat cheese, pomegranate seeds, dried cranberries, toasted walnuts, or candied pecans.
- Glaze: Finish the squash with a glaze using maple syrup or honey, butter, and spices. Add balsamic vinegar for some acidity to balance the sweetness.
How to Cut Butternut Squash
The hardest part of this recipe is cutting the squash in half, which actually isn’t that hard with the right technique.
- Trim the stem: Start by trimming the stem side (small end) by holding the squash and trimming about ½ inch off the top of the squash. You can also trim the bottom end, but it isn’t necessary.
- Cut the squash in half: Cut the squash in half vertically using a sharp knife. You will have to apply some pressure and sometimes using a rocking motion can help. Go slowly and apply pressure as you cut.
- Scoop out the seeds: Use a spoon to scoop out the seeds and squash bits attached to the seeds. Discard them or clean them and save them for roasting.
How to Serve Whole Roasted Butternut Squash
There are so many ways to serve and use whole roasted squash.
- As a side dish: This squash, especially with the glaze, is a perfect side dish on all its own. We serve it at almost every holiday and it is always a hit.
- Stuff the squash halves: Whenever I make roasted squash, I always cook some extra halves to stuff for another meal. Normally I just add a simple combination of cooked brown rice, ground turkey sausage, and spinach. It’s filling and delicious.
- Make soup: When it comes to fall soups, this slow cooker butternut squash soup is a favorite. Use your roasted butternut squash soup to cut the cooking time down to less than one hour.
- Make pasta sauce: Scoop out the roasted squash and blend it with milk or cream, Parmesan cheese, and lots of black pepper for a rich and creamy pasta sauce. For a lighter option, use vegetable broth or the pasta cooking liquid to thin the squash into a sauce.
- Use it for desserts and baking: Use the roasted squash in place of “pumpkin” in any of your favorite fall desserts and baked goods including pies, breads, muffins, brownies, and cakes. It is also delicious in oatmeal instead of pumpkin.
