How To Make Vegan Spaghetti Squash

First, you need to cook the spaghetti squash. There are many ways you can cook a squash.

Some people love to cook squash in a crockpot, microwave, or boil it. Here we bake the squash in the oven to add a lovely roasted flavor.

Step 1: Baking the Spaghetti Squash

The best way to cook the spaghetti squash is to bake it in an oven preheated to 350°F (180°C).

First, cut the sides of the vegetable. Next, halve the squash lengthwise to end up with two ‘boats’.

Scoop out the seeds from the vegetable using a spoon, discard the seeds or wash and keep them for later.

You can roast the seeds to make crunchy appetizers.

Then, cover a large baking sheet with parchment paper and place the two pieces of spaghetti squash, flesh down, onto the tray.

Bake for 30 to 45 minutes or until it’s easy to prick the skin with a knife.

The baking time varies depending on the size of your squash. If you overbake the squash, it won’t form noodles. Just a mushy soft puree.

So check how it bakes as it goes. You know it’s almost ready to take out of the oven when:

• The squash skin darkens to light brown.
• A knife can be inserted easily onto the tough skin.
• The strands of the squash are yellow/golden but still firm if scraped with a fork.

Step 2: Making vegetable noodles from spaghetti squash

Remove the baked spaghetti squash halves from the tray and place them on a cooling rack or plate, flesh up.

Set aside for 15 minutes to let the steam come out.

Then, use oven mittens to hold the squash with one hand, and with a fork, pull apt the flesh to form vegetable noodles.

Place the noodles aside in a mixing bowl.

You can keep the squash skins to refill later and use them as a dish, as seen in the picture.

Or you can discard the squash skin and cook this recipe as a spaghetti squash casserole in a 9×13-inch baking dish.

Making The Vegan Alfredo Sauce

This recipe uses an easy homemade vegan Alfredo sauce to stuff the spaghetti squash.

Vegan Alfredo Sauce Ingredients

To make the sauce, you need:

• Olive oil or vegan butter
• Flour or arrowroot flour for a gluten-free option
• Garlic cloves – crushed
• Almond milk
• Coconut cream or soy cream
• Nutritional yeast – a perfectly vegan-friendly ingredient.
• Salt and pepper
• Chopped parsley

Cooking Vegan Alfredo Sauce

First, melt the vegan butter in a medium saucepan over medium heat.

Then, add garlic and cook for 30 seconds until flavorsome.

Remove from heat and, using a wooden spoon, stir in flour of choice until it forms a creamy yellowish paste.

Return the saucepan over medium heat, whisk in unsweetened almond milk and coconut cream and keep cooking/whisking until it thickens and a light simmer forms.

When the sauce thickened, whisk in nutritional yeast, chopped parsley, salt, and pepper.

Keep cooking for 1 to 2 minutes until the yeast is well distributed.

If the sauce is too thick for your liking, add 1/4 cup extra unsweetened almond milk, up to 1/2 cup for a more liquid sauce.

Serving Vegan Alfredo Spaghetti Squash

Now, pour the vegan alfredo sauce onto the vegetable noodle. Stir the noodles to evenly distribute the sauce over the spaghetti.

Finally, place the alfredo squash noodles into a large baking dish or into the squash skins.

Sprinkle grated vegan cheese on top of the dish if desired and return to the oven for 15 minutes until it’s piping hot.

Serve immediately with extra chopped parsley on top or a drizzle of garlic-infused olive oil.

Storing Spaghetti Squash Alfredo

This gluten-free, vegan squash casserole stores for up to 4 days in an airtight container in the fridge. Or you can freeze the container for up to 3 months.

Rewarm in a saucepan or in the microwave until piping hot.
