Roasting spaghetti squash in the oven is by far the best way to prepare it because it brings out the best flavor and dries it out completely, so your dish is not watery.
Why Is It Called Spaghetti Squash?
Spaghetti squash is a low carb vegetable that makes an excellent pasta dish. When cut open, the inner flesh contains many seeds and a tough, somewhat stringy texture.
When cooked, it becomes soft and turns into fine, thin spaghetti-like strands, making it an amazing spaghetti or pasta replacement.
Spaghetti Squash Nutritional information
Spaghetti squash, also called vegetable spaghetti or noodle squash, is a winter squash that is firm and hard and is bright yellow or orange in color.
It contains healthy vitamins such as beta-carotene, potassium, vitamin A, folate, and folic acid, and anti-oxidants.
Ingredients Used
How to Make Keto Spaghetti Squash

- Preheat your oven to 400F. Poke about 4 to 5 holes on each side of the spaghetti squash vertically with a sharp knife. The holes don’t have to be that deep. Microwave for 3-4 minutes; I’m usually good to go after just three minutes, but you can do one more minute if it’s still too hard. When done, allow to cool a bit, cut out the stem and cut open vertically. Use a metal spoon to scoop away all the seeds from the center.
- Use a brush to lightly apply some olive oil to it and sprinkle just a bit of salt and pepper.
- Line a baking pan with parchment paper, and place the squash halves on the parchment paper. The squash cut-side should face down. Place it in the hot oven and set the timer for 30 minutes.
- When the spaghetti squash has just 10 more minutes on the timer, prepare the sauce. Chop ¼ bell pepper and ¼ onions (roughly one cup each) and set aside.
- Add 2 tablespoons of olive oil to a large skillet, and when heated, add the chopped onions. After a minute, add the chopped bell peppers and stir for about 5 minutes. Simmer on medium-high heat.
- When the spaghetti squash is done, bring it out and let it cool down for a few minutes as it will be scalding. When it cools down a bit, remove as many strands as you can from the inside of the squash, using a fork. The squash strands should look and feel like spaghetti.
- Add the spaghetti squash and spices to the pan with the veggies and stir thoroughly for about 5 minutes on medium heat. Garnish with fresh parsley and pepper flakes, if you wish, and you’re ready to eat!

Storing and Reheating
Spaghetti squash can be stored for 3-5 days in an airtight container in the refrigerator. You can also freeze for up to 3 months.
To reheat, thaw the frozen spaghetti squash in the refrigerator overnight. Then reheat on the stove with very little water.

Tips and Recipe Variations
- Spaghetti squash can be a bit challenging to cut, especially if it is your first time. The outer skin is quite hard and firm, but you need to cut through it, and this can be a bit hard for some because you need to use quite a bit of force. A slightly easier way is to poke holes in the spaghetti squash and microwave for a few minutes.
- The poking-holes part is VERY crucial; please do not put a spaghetti squash in the microwave without poking holes in it. It just might explode and possibly damage your microwave. You need to poke holes in it to release the steam.
- If you like your spaghetti firm in texture, 30 minutes is all you need. If you want it softer, leave for an extra 10 minutes in the oven.
- After shredding the spaghetti squash and adding it to the pan with the veggies, taste for salt BEFORE you add more spices. Remember, some salt and black pepper were already added before the spaghetti squash was put in the oven.
- Use your favorite sauce like low-carb marinara sauce, pasta sauce, or alfredo sauce.
