Key Ingredients

This recipe has two simple components: the spaghetti squash and the creamy sauce! I’m going to break it down into two sections so you can set your ingredients aside for each part of the recipe.

Roasted Squash Ingredients:

Spaghetti squash: Cut in half, lengthwise
Olive Oil: Not too much
Seasonings: Salt and pepper
Cheese: Mozzarella (shredded) and parmesan (grated)
Parsley: Chopped for serving

Creamy Sauce:

Butter: Unsalted or ghee.
Garlic: Just two cloves.
Flour: Unbleached. For a gluten-free version use a gluten free blend or cassava flour. Both work well.
Milk: Regular milk, or heavy cream.
Broth: You can use chicken broth, I also like to use vegetable broth for this recipe.
Cheese: You will only need parmesan cheese for the sauce!
Pepper: White pepper that is, or you can use black.
Salt: To your taste.

How to Cook a Roasted Spaghetti Squash

Step 1: Preheat

First things first, preheat the oven to 375F.

Step 2: Cut Squash

Then cut the squash lengthwise in half and gently remove the seeds.

Step 3: Season

Next, rub the insides lightly with olive oil and sprinkle with salt and pepper.

Tip: Overdoing it on the olive oil and salt can end up with a mushy squash, so coat it lightly.

Step 4: Bake Squash

Next, place the cut side down on a baking sheet, and bake for 45 minutes. The time may vary depending on the oven, but you will be able to prick the skin with a fork with the squash still holding its shape.

Step 5: Remove Spaghetti Squash

Remove from the oven and carefully flip over each half. Use a fork to separate spaghetti.

Make the Sauce:

Heat butter in a medium saucepan.
Add garlic and cook for 1 minute.
Add flour, cook stirring on low heat for 1 more minute.
Remove from heat, add milk and whisk until completely combined and there are no lumps. Then add chicken broth and cook until thickened.
Add grated parmesan, white pepper and salt to taste.
Transfer squash spaghetti to the saucepan and stir until combined.
Divide sauce covered spaghetti between the skin shells. Top with shredded mozzarella and parmesan. Bake for 10 minutes or until the cheese has nicely browned. I broiled it for the last 3 minutes.

Expert Tips:

While it’s best to make homemade sauce, substitute marinara or another jarred or canned spaghetti sauce.
Add red pepper flakes to the sauce as you’re cooking it for a touch of subtly spicy flavor!
If you have leftovers, try to eat them within 2 days so the spaghetti doesn’t go bad.
Serve with grilled chicken or lamb as the perfect pairing for a family favorite dinner!

Recipe FAQs

Is there a difference between roasting and baking squash?

Yes, there’s a difference! Baking a spaghetti squash will work well, but you have to bake it at a lower temperature and for a longer period of time. This will result in an even bake that doesn’t have much browning.
To roast a spaghetti squash, cook it at a higher temperature for a shorter period of time. This will create more of a browned and crispy outside with a creamy inside.

How do I stop my spaghetti squash from getting watery?

Spaghetti squash often gets watery if you use too much salt and/or oil. Squash has a high water content and salt draws it out, so while you do want to season your squash with salt, you want to make sure you go easy on it.

How long to cook spaghetti squash?

At 375F, the squash cooks in just 45 minutes. Then, you can use a fork to separate the noodles within the squash.
