Uhm, why hasn’t anyone told me how good spaghetti squash is? This is totally one of those vegetables like Brussels sprouts and butternut squash that I would not have liked when I was younger, but, wow, just, wow!!! Since first testing recipes with spaghetti squash, I’ve gone back to the store and bought them multiple times now! I find myself daydreaming of what I can stuff in them!

So this was my first attempt at roasting spaghetti squash. I played it safe with cheese, cream cheese, and pesto. Flavors I knew I’d love. I found that they needed a good sprinkle of salt and pepper. As well, they took longer to roast than I anticipated. But, all is well that ends well and it ended pretty dang tasty!

Here’s what I did.


If you’re new to the spaghetti squash game, here are a few nifty facts.

It’s a winter vegetable and it really does separate into spaghetti-like strands after it’s cooked. As well, it’s naturally slightly sweet and buttery tasting without adding anything. (Literally, I’m eating this as I type and, coincidently, making a mess on my notes! It’s so worth it though.)

This vegetable is just so dang easy to cook too! Other than popping a potato or sweet potato in the microwave, spaghetti squash is one of the easiest items to cook. You can simply slice it in half, season it, and roast it in the oven.

Spaghetti squash is a low-carb alternative to actual spaghetti. It’s very versatile because it takes on whatever seasoning you add to it just like pasta.

Spaghetti squash is low in calories and carbs but high in fiber, vitamin C, manganese, and vitamin B6. As well, it’s rich in antioxidants,  It also contains small amounts of thiamine, magnesium, folate, calcium, and iron.

First, spaghetti squash is large and cumbersome. It’s just not easy to handle but I learned a nifty trick. Microwave the squash for a few minutes in the microwave. This makes them much easier to cut in half. Also, be sure you’re using a sharp chef knife. I dull knife is much more dangerous than a sharp one. (I’m going to link some of my favorite chef knives below. They make great gifts!!)

I didn’t want to make a roux so I chose cream cheese for the creamy base. Then I shredded white cheddar, mozzarella, fontina, and parmesan.

You can use more or less of any of these ingredients to suit your taste. As well, you can sub any of the cheese. However, I don’t recommend replacing the Parmesan. It adds so much flavor.

  1. Microwave the squash and cut it in half.
  2. Scrap the seeds out.
  3. Sprinkle the inside with salt and pepper. Add red pepper if you want.
  4. Mix the cheese, pesto, and cream cheese.
  5. Cover with foil and bake.
  6. Remove from the oven. Stir the cheese mixture into the squash.
  7. Enjoy!

And that’s just how easy it is!
