Why spaghetti squash is my favorite pad Thai swap

London Brazil taking a bite from a bowl of food.

I have made quite a few spaghetti squash recipes over the years, but this Spaghetti Squash Pad Thai might be my favorite of the bunch. It has all the sweet, savory takeout flavor I crave, with roasted spaghetti squash standing in for the rice noodles.

The whole thing is naturally gluten-free, and a couple of easy swaps make it Paleo or Whole30 friendly. Coconut aminos for the soy sauce, coconut sugar for the brown sugar, and you are set.

The squash keeps it lighter and lower in carbs, and honestly nobody at the table misses the noodles. Once it is roasted, you just toss the strands right into the sauce with the chicken, veggies, and eggs.

If you love cooking with spaghetti squash as much as I do, my Spaghetti Squash Carbonara and Spinach Artichoke Spaghetti Squash Boats are two more I come back to.

Ingredients and Substitutions

For the exact measurements and detailed instructions, please see the recipe card below.

  • Spaghetti squash: Look for a medium to large spaghetti squash for the best results. Avoid extra large or small ones as they won’t have good flavor or texture.
  • Vegetables: Other than the squash, you’ll need chopped green onions and shredded carrots.
  • Chicken: Boneless skinless chicken breasts are the leanest option, but you could opt for chicken thighs if you prefer.
  • Pad Thai sauce: While you can grab a jar at the store, it’s so easy to make your own. You only need soy sauce, fresh lime juice, brown sugar, chili garlic paste, and rice vinegar!

Step-by-step Instructions

Please see the recipe card below for the full instructions, ingredient amounts, and a printable recipe.

Roast the spaghetti squash

There are numerous ways you can cook spaghetti squash, and trust me, I have tried them all!

Some recipes will call to add a bit of water, but don’t listen to them! Doing so will make the spaghetti squash way too soggy.

For the best results, cut your whole spaghetti squash in half lengthwise. If you have trouble cutting your spaghetti squash simply put in the microwave for a bit or pop it in the oven while it is preheating for a few minutes. The knife should cut through the spaghetti squash with ease!

Scoop out all of the seeds until you get to the flesh of the spaghetti squash. Drizzle a touch of olive oil and sprinkle a bit of sea salt on the inside halves of the spaghetti squash.

Place your spaghetti squash halves cut side down on a parchment paper lined baking sheet. Bake in a 425℉ preheated oven for 40 to 50 minutes, until the insides shred easily. Smaller spaghetti squash will take less time, while bigger squash will take longer.

The Sheet Pan I L❤️VE!

Your veggies will end up steaming instead of roasting if you overcrowd the pan. So my tip… use the largest sheet pan you have and spread everything out!

These are the sheet pans I use and love!

Cook the veggies and eggs

Add 2 tablespoons of oil to a large non-stick skillet over medium heat. Stir in the white parts of the chopped green onions, minced garlic, and shredded carrots. Cook for 2 to 3 minutes.

Push the vegetables to the side of the skillet and add the cracked and whisked eggs. Scramble for 2 to 3 minutes more, still over medium heat. 

Mix the veggies and the eggs together, then remove from the skillet to a plate.

Cook the chicken

Toss the thinly sliced chicken breast pieces in the starch or flour and black pepper. Be sure to tap to remove the excess. 

Add 2 more tablespoons of oil to the skillet, and cook the chicken over medium heat for 6 to 8 minutes. It should be cooked through.

Make the pad Thai sauce

Traditional pad Thai sauce is made with lime juice, brown or white sugar, rice wine vinegar, and soy sauce.

You simply add all of your pad Thai sauce ingredients to a medium-sized bowl and whisk them together! Once the chicken is done cooking, add the flavorful sauce to the skillet and cook for 2-3 minutes.

Fill the squash

When the spaghetti squash has finished cooking, use a fork to shred the inside until you have “noodles.”

Carefully add equal amounts of the chicken, sauce, veggies, and eggs to each half.

Alternatively, you can add the spaghetti squash noodles to the chicken and sauce, then stir in the veggies and eggs. Toss everything together.

FAQs

How many carbs are in spaghetti squash? 

There are roughly 7 grams of carbohydrates and 1.5 grams of dietary fiber in 1 cup of spaghetti squash. A 4-pound spaghetti squash will yield about 5 cups of spaghetti squash. So, you are looking at around 35 grams of carbohydrates and 27 net carbs per spaghetti squash. This recipe is a lighter, lower-carb option than classic pad Thai.

Why is my spaghetti squash mushy and not stringy? 

The best way to ensure you get noodle-like spaghetti squash is to avoid adding water to the roasting pan, and use only a little oil. Then, use a fork to gently fluff the insides after baking.

Can I make spaghetti squash pad Thai ahead of time?

You sure can. Roast the spaghetti squash up to 2 days in advance and keep it in the fridge, then cook the chicken, veggies, and sauce when you’re ready to serve. Leftovers keep in an airtight container for 4 to 5 days.

What can I use instead of chicken breast?

Chicken thighs work great if you like a little more richness. Shrimp or tofu are both easy swaps too, and rotisserie chicken is a nice shortcut when you’re short on time.

Can you freeze spaghetti squash pad Thai?

Freezing isn’t recommended for this one. Spaghetti squash releases a lot of water as it thaws, so the texture turns soft and watery. It’s best enjoyed fresh or from the fridge within 4 to 5 days.

Notes

  • Can use gluten-free soy sauce or Tamari if not on a soy-free, Paleo, or Whole30 diet.
  • Eliminate bean sprouts and peanuts if on a Paleo and Whole30 diet. Finely chopped almonds can replace the peanuts, if desired.
  • Nutritional information is calculated with 1 large spaghetti squash.
Prep-Ahead Instructions:
You can easily roast the spaghetti squash a day or two in advance.
Storage Directions:
Keep leftover spaghetti squash pad Thai in an airtight container in the fridge for up to 4 to 5 days. Freezing is not recommended, since the spaghetti squash releases a lot of water and turns soft once thawed. Warm leftovers back up in a skillet over medium heat for the best results.

    I don’t usually leave reviews but had to leave one for this. It is SO GOOD!!
    I added a spoon of peanut butter to the sauce. Otherwise made the recipe as it is. My husband and I both demolished it. Will be making again!
