Don’t let this simple recipe for Twice Baked Butternut Squash fool you. Sometimes the best tasting (and healthiest!) recipe is also the simplest recipe.

Every time spring arrives, I get giddy and excited. There’s something about nature getting rejuvenated that rejuvenates me. And spring produce and flavors? Oh so delicious.
Squash is one of those fall favorites that I look forward to every year. Although my kids aren’t too crazy for squash, my husband and I are. If I had to choose a favorite squash, I’d have to pick the butternut squash.
It’s mildly sweet, so full of flavor, and it doesn’t turn to mush when you cook it.

Why this recipe is so great
My favorite way to prepare butternut squash is also one of the simplest recipes: Twice Baked Butternut Squash. A simple brush of extra virgin olive oil and seasoning of salt and pepper is all your squash needs before you roast it in the oven until fork tender.
Then, you scoop out the flesh, mash it up, add some fresh thyme and transfer it to a baking dish to bake some more. If you want some more flavor, add some butter.
But, please, don’t add brown sugar or marshmallows. I have never understood why Americans take a perfectly delicious and already naturally sweet dish and drown it with more sugar. Trust me, it doesn’t need it.
This can easily be made in advance, too, making your holiday meal prep stress free.
Ingredients you need
- Butternut squash: You can prepare this with acorn squash and pumpkin as well.
- Extra virgin olive oil: When I roast the squash the first time, I coat it with olive oil. When I mash and bake it, I sometimes add butter to it. So you choose your favorite fat and flavors.
- Thyme: You can substitute with fresh rosemary, chives, marjoram or oregano.
- Salt and pepper
