Sooooo…..you need to make this recipe.

I have made it twice already in less than a week! It is healthy and will satisfy your craving for lasagna.

Spaghetti Squash is versatile!

Spaghetti squash is such a great vegetable because you can do so much with it, like how this recipe uses it as a bowl for the lasagna.

Spaghetti squash is a Fall/Winter vegetable and is a perfect alternative for pasta and much lower in calories. It is naturally gluten free (for those of you with Celiac disease or gluten sensitivities).

Eating a more plant based diet will provide your body with more fiber, vitamins, and other nutrients that can help prevent obesity and other chronic diseases

If you are looking for a low-carb option, spaghetti squash is going to be your best friend! You can save a ton of calories by eating spaghetti squash and won’t have that overly full feeling you may get after eating a plate of regular spaghetti!

Spaghetti squash vs pasta:

  • Both are low in fat, salt, and provide fiber in our diets. Squash has antioxidants you won’t find in regular pasta.
  • Pasta can have up to 182 calories (1 cup of small shells) vs spaghetti squash only has 42 calories for 1 cup.
  • Pasta has 35.5g of carbohydrates while the squash only has 10g of carbs (per 1 cup)

How do I cook my spaghetti squash?

#1: In the oven!

Cut your squash in half lengthwise with a sharp knife (be careful!) and scoop the seeds out, just like you would do with a pumpkin on Halloween.

Pro tip: If you want, you can save the seeds too and roast them like pumpkin seeds!

Next, brush the inside of the squash with 1-2Tbsp Extra Virgin Olive Oil and sprinkle with salt, pepper, and garlic powder.

Place the halves on a baking sheet lined with foil and make sure the squash is placed with the skin side up so the cut part faces down.

Cook in a preheated 425° F oven for 30-45 minutes, or until tender.

You can also place the squash in the microwave but I like using the oven best to give it that roasted flavor.

When the squash is ready, scrape a fork into the flesh and spaghetti-like strands will appear. It is actually pretty neat! Fluff the strands just enough to make room for all the filling.

#2 Make it in your Instant Pot or Pressure Cooker!

Cut the squash in half and scoop out the seeds.

Place the trivet down on the bottom and then add 1 cup of water.

Arrange the squash in the Instant Pot

Close the lid and make sure the Instant Pot is set on sealing and not venting!

Set to manual, high-pressure for 7 minutes. If you have a rather large spaghetti square (2 pounds + cook for 10 minutes)

When the timer goes off, use the quick release method by switching the valve from sealing to venting carefully with a towel so you do not burn your hand!

Wait about 3-5 minutes for the steam and pressure to dissipate.

Open the lid and test the squash. Use the tines of a fork to separate the cooked squash. Take a bite to test that it’s done. (I like my squash tender but not mushy).
