Spaghetti Squash Mac and Cheese – Creamy, Light, Delicious

I’ll be the first to admit it—mac and cheese is sacred in our house.

It’s that warm, gooey comfort food my kids ask for on rainy days, after tough school weeks, or honestly… any time. But as a mom who’s trying to sneak in more veggies without triggering a full-on dinner rebellion, I needed a way to make it lighter. Healthier. Still cheesy. Still cozy.

Enter this Spaghetti Squash Mac and Cheese.

It’s cheesy (without the cheese), packed with veggies, and still hits all the same notes as the classic. Even better? My kids had no clue they were eating squash the first time I served it. That’s when I knew we had a keeper.

Whether you’re gluten-free, low-carb, dairy-free, or just looking for a dinner that makes you feel good without giving up flavor, this one is for you.

How to Make Spaghetti Squash Mac and Cheese Step-by-Step

This recipe is super beginner-friendly. You’ll roast the squash, blend a creamy sauce, then bake it all together. It sounds fancy, but it’s weeknight do-able.

Step 1: Roast the Spaghetti Squash

1. Preheat oven to 350°F
2. Cut squash in half lengthwise and scoop out seeds with a spoon
3. Rub olive oil over the inside, then sprinkle with salt
4. Place squash halves cut-side down on a baking sheet
5. Bake for 20 to 30 minutes, depending on size
6. Let it cool slightly, then scrape out the “noodles” using a fork
7. Transfer squash to a large mixing bowl

Tip: Don’t overbake or it’ll get mushy. You want strands that hold up, like al dente pasta.

Step 2: Make the Cashew Cream

1. Add raw cashews, warm water, garlic, onion, salt, and nutritional yeast to a blender
2. Blend on high until smooth and creamy
3. If too thick, add 1 to 2 tablespoons more water and blend again
4. Set aside

This sauce is the heart of the dish. It’s rich, cheesy, and surprisingly satisfying.

Step 3: Mix Everything Together

1. To your bowl of squash, add:
   • 2 eggs
   • Spicy brown mustard
   • Parsley
   • Nutmeg (if using)
   • Cashew cream sauce
2. Mix everything together until well combined

It’ll smell cheesy and nutty and comforting—this is your “mac and cheese” moment.

Step 4: Bake It

1. Grease ramekins or a casserole dish
2. Scoop the mixture evenly into your baking dish
3. Sprinkle the tops with nutritional yeast and smoked paprika
4. Bake at 350°F for:
   • 20 minutes (for ramekins)
   • 30 to 40 minutes (for a casserole dish)
5. Let cool for 5–10 minutes before serving

I like to sprinkle a little fresh parsley on top before serving. It makes it feel restaurant-worthy.

Easy Add-ins and Swaps for Your Family

One of the best things about this dish is how easy it is to personalize it based on what your family likes.

Want it cheesier?

• Mix in a few cubes of Laughing Cow cheese
• Sprinkle with grated gruyere or shredded vegan cheddar

Add protein

• Stir in cooked chicken, turkey sausage, or crumbled bacon
• Top with a crispy chickpea crumble for plant-based crunch

Spice it up

• Add red pepper flakes or a tiny dash of hot sauce to the cashew cream

Make it vegan

• Skip the eggs and use a flax egg or just omit (texture will be softer but still delish)
