The subtle (some might say bland) flavor of spaghetti squash basically begs for seasoning, but you don’t need a pasta sauce to spice things up. By cutting the spaghetti squash in half prior to roasting, you have an opportunity to season the flesh before it cooks—so if you want to experiment with different preparations, this method from food scientist and author Jessica Gavin will be right up your alley.
1. Preheat the Oven to 400 Degrees
The high temperature is helpful if you aren’t serving your veg with spaghetti sauce, since it will caramelize the squash and impart a deeper roasted flavor.
2. Halve the Squash
With a heavy-duty knife, cut the spaghetti squash in half lengthwise. Since the skin and flesh is quite firm prior to cooking, it might be helpful to bundle the squash in a dish towel for a firmer grip before you insert the knife and start cutting.
3. Remove the Seeds
Use a large metal spoon to scrape out the seeds and pulp from the both halves of the squash.
4. Rub with Oil and Seasoning
Brush or rub the flesh of the squash with olive oil—any oil with a high smoke point will do, but olive oil gets bonus points for its bigger flavor—and sprinkle with a generous amount of kosher salt and cracked pepper. This is also the point at which to get creative with any additional spices you’d like to add to the mix.
5. Roast for 40 Minutes
Place both halves cut size down on a baking tray and put them in the oven to bake for roughly 40 minutes, or until the flesh is tender and a knife can cut through the skin like butter.
6. Scrape
Just as you would with a whole-roasted spaghetti squash, grab a fork and scrape to loosen the flesh into strands of squash. Plate the squash and dig in—or for an elegant presentation (and fewer dishes), gobble it up straight out of the gourd. No judgment here.
