FAQs About Spaghetti Squash

When Is Spaghetti Squash Ripe?

It’s pretty much impossible to purchase a spaghetti squash that isn’t ripe these days. If they are yellow in color and have hard skin, they are ripe.

What Is The Glycemic Index Of Spaghetti Squash?

The glycemic index number of spaghetti squash is only 15, while the glycemic load is a very low 2.

How Much Healthier Is Spaghetti Squash Than Pasta?

I think we can all agree that vegetables are typically far healthier for you than pasta. Spaghetti, depending on the brand, has approximately 100 calories per serving and a whopping 42 grams of carbs. Just for the record, 1 serving is 2 oz. Far less than a lot of people eat in one sitting!

Spaghetti squash, on the other hand, only has only 17 calories for that same 2 ounces and only 4 grams of carbs. That’s a pretty stark difference!

How Do You Find The Longest Strand Of Spaghetti Squash?

Well, for starters, you don’t cut the squash the way I did in this recipe. (For this recipe, shorter strands are best).

But to get longer strands, you’ll want to cut your squash into thick rings because the strings do not run from end to end. They wrap around the squash, pretty much in circles. So cutting rings instead of slicing the squash in half lengthwise, will give you long spaghetti squash strands. (Hint: look at how the squash is cut below, and don’t cut it that way. Cut the other direction to make rings.)

Is Spaghetti Squash A Low Fodmap Food?

75 grams (approximately 1/2 a cup) is considered low Fodmap. That being said, I cannot vouch for the rest of this recipe.

Recipe Variations

Once everything is in the mixing bowl to be mixed, you can add any of these for extra flavor:

  • 2 cups marinara sauce or tomato sauce (no sugar added)
  • 1 cup parmesan cheese
  • 1 to 2 cups ricotta (you can also use full-fat cottage cheese for more of a spaghetti squash lasagna flavor!)
  • Fresh basil (instead of just using it for garnish)
  • 1 tsp. of red pepper flakes if you want some spice.

About The Ingredients

Spaghetti squash – Just get a medium-sized squash with nice, hard, yellow skin with few blemishes.

Oil – Any type you are comfortable cooking with.

Red onion – The measurement is approximately 1 large, red onion.

Garlic – You want the whole head of garlic. The bigger, the better. (In my humble opinion)

Sliced mushrooms – You can use white or brown mushrooms.

Baby spinach leaves – Regular spinach works too, but I would chop it up a bit to avoid large pieces.

Salt – I used pink Himalayan salt, but you can use whatever you normally cook with.

Black pepper

Italian seasoning – This is a simple herb mix. You can purchase it in the spice aisle at any grocery store or make your own using this recipe.

Ground turkey – You can use ground beef if you prefer. Ground chicken will work too.

Grated mozzarella cheese – If you want to play around with the flavors, you can try different types of cheese. Parmesan is never a bad idea.

Fresh basil – chopped or sliced for garnish

How To Make

Two spaghetti squash halves turned cut side down on a baking pan.

Preheat your oven to 400°F. Cut the spaghetti squash in half lengthwise and scoop out the seeds and membranes with a spoon. Turn them cut side down and place the pan in the oven. Pour a ½ inch of water into the pan and bake for 40-50 minutes, or until you can easily push a knife through the squash.

Reheating Italian Spaghetti Squash Boats

From Frozen – Thaw for a full 24 hours (or as needed) in the fridge.

From Fridge – Reheat this in the microwave, or in the oven at 325 F. until warmed through. If it takes a while to heat up in the oven, you may want to cover it with a loose piece of foil so the oven doesn’t burn anything as it warms.
