This spaghetti squash has become a real favorite of ours. It is hearty, tasty, and is quick to prepare. I hardly ever cooked spaghetti squash because it seemed to take FOREVER in the oven. Then I thought one day, could it work in the Instant Pot? I was so thrilled to find out that yes, it does cook in the Instant Pot and in only 8 minutes! That's amazing! What a time-saver!

🍈 A great vegetarian meal
My family and I have decided to cut down on our meat intake and enjoy more vegetarian meals during the week. This was in part to save money as well as perhaps eat even healthier. It was a struggle; first, the kids hated it, but we don't even miss the meat with this squash recipe. It is so hearty and satisfying and seriously filling.
We grow our own vegetables in the garden and had a bumper crop of squash. The beautiful thing about this winter squash is it keeps for a very long time. It is March here, and our spaghetti squash is still perfect! As long as it's in a cold room, it should last until the next gardening season.

- Also contains a small amount of thiamine, magnesium, folate, calcium, and iron.

👪 How do you know if spaghetti squash is ripe?
The squash is ripe when it turns a golden yellow or a dark yellow color. The skin of the squash will be very thick and hard. If you use your fingernail to poke the squash, your nail shouldn't penetrate the squash.
🔪 How to cut it
With your dominant hand, use a sharp chef's knife to cut the squash in half from stem to base, keeping your hand far away from the knife. Next, using a spoon, scrape out all the seeds. We like to save our seeds and dry them out to use them to grow spaghetti squash in the garden again.

🥘 Ingredients
- 1 large ripe spaghetti squash
- 1 tablespoon olive oil
- ½ onion
- 3 cloves of garlic
- 3 cups of marinara sauce (out of a jar or homemade).
- 1 teaspoon oregano
- Salt to taste.
- Pepper to taste.
🔪 Instructions
- Carefully cut your squash in half from stem to base, scoop out all the seeds.
- Place the trivet that came with your Instant Pot on the bottom of the pressure cooker.
- Add 1 cup of water to the pressure cooker.
- Put in your spaghetti squash facing each other, but with space between them. If your squash is too big to fit, cut it into quarters.
- Secure the lid on the Instant Pot, set it to "sealing".
- Set to 8 minutes on high pressure.
- Meanwhile, saute ½ onion and 3 cloves of garlic in 1 tablespoon of olive oil until translucent, about 4 minutes.
- Add 3 cups of marinara sauce and 1 teaspoon of oregano to the onion and garlic mixture and heat it up.
- When the timer of the Instant Pot beeps, signaling that it is done, switch to "venting" to release steam. Be sure to use a long-handled spoon or oven mitt so you don't get burned from the steam as it spurts out!
- When the pressure is fully released and the pressure indicator has dropped, remove the lid.
- Then, use tongs to move the spaghetti squash to a cutting board.
- Your squash should be tender when pierced with a fork.
- Using a fork, pull up threads of "spaghetti", use a spoon to transfer the "spaghetti" to the pot with the marinara sauce, or you can just place "spaghetti" on a plate and serve the heated marinara sauce on top.
- Alternatively, if mixing the "spaghetti" noodles into the marina sauce, after mixing it well, spoon the marinara mixture back into the squash "boat".
- If you like, you can put mozzarella cheese or parmesan cheese on top and broil in the oven for a couple of minutes.
- However, we like to add cottage cheese to ours and simply dig in! Yum!
- Enjoy!

📖 Variations
I have tried many different ways of serving spaghetti squash; with parmesan cheese and salt and pepper, but that got a little boring. This recipe with spaghetti squash with marinara sauce is so delicious, plus you can change it up to your own tastes!
Heat the marinara sauce and serve it over the spaghetti squash strings on a plate, and top with parmesan cheese for an even quicker meal.
Don't want to eat vegetarian? Add some cooked sausage or cooked ground beef or turkey. You could also add extra cheese for extra cheesy goodness!
