Roasted Parmesan Spaghetti Squash


What is Spaghetti Squash?


There are quite a few varieties of squash. Spaghetti squash is a winter squash. The other winter squash you know is butternut squash. So how are the two different? According to


The most obvious difference is in the texture. Spaghetti squash, unlike any other squash variety, has a unique stringy texture once cooked. It is quite neutral in flavor. Butternut squash, on the other hand, has a creamy texture and a sweet nutty flavor. Both are used in making casseroles, soups, and salads. There are many cooking methods that can be used to prepare both butternut and spaghetti squash, including baking, roasting, and steaming.

Roasted Parmesan Spaghetti Squash


This veggie is nature’s own seasonal spaghetti. But please, don’t get fooled by it. If you are looking for a traditional pasta taste, you won’t find it here. It may look similar, but spaghetti squash has a much earthier taste with a bit of a bite to it.



2 medium spaghetti squash
½ cup parmesan cheese, grated
¼ cup butter, melted
3 tablespoons olive oil
½ teaspoon garlic powder
salt & pepper, to taste
2 tablespoons fresh parsley, chopped (optional)



Begin by pre-heating your oven to 400°.  Line a large baking sheet with foil, parchment or a silicone baking mat.


Trim the top and bottom off of the squash. Cut the squash in half lengthwise. The easiest way I have found to do this is so you get an even cut is by standing the squash upright on a flat surface and using a sharp knife to cut down the center. Scoop out the guts and seeds. You can save the seeds if you’d like to roast them. I’ve personally never done that, but it sounds like it would be easy enough.


How to Prepare a Spaghetti Squash



Brush the inside and edges of the spaghetti squash with olive oil, and then sprinkle with the garlic powder and salt and pepper, to taste. Place the squash halves on the lined baking sheet, cut side down. This keeps the moisture from pooling inside the squash.


Bake on the center rack of the oven for 40 minutes, or until squash is fork tender. The cooking times will vary depending on the size of the squash, so adjust accordingly.


Remove from oven and cool for about 10 minutes before turning over. Then, carefully shred the flesh with a fork so that it creates spaghetti-like strands. Leave the “spaghetti strands” inside the squash shell. Sprinkle half the parmesan over the strands and drizzle with melted butter. Top with the remaining cheese and additional salt and pepper, if desired.


Return the squash to the oven for an additional 5 minutes or until the parmesan cheese and edges of squash begin to brown. Garnish with optional chopped fresh parsley, and serve!

    With its curves and thick skin, tackling a spaghetti squash can be daunting for even seasoned cooks. But all you need is a sharp chef s knife. First, check if there s a naturally flat side of the squash. If the squash settles sturdily on a side without wobbling, you re good to go. It s more likely, however, that you ll need to carefully cut a thin slice off one long side to create a stable resting place for the squash.
