Ingredients You’ll Need

This recipe keeps things friendly and unfussy—each ingredient serves an important role, contributing creamy texture, aromatic depth, or just the right kick of heat. Here’s what you’ll need to build the memorable flavor foundation for Spicy Spaghetti Squash Noodles:

Full fat coconut milk: The creamy base that makes the sauce rich and indulgent—don’t skimp on the full-fat version for that luxurious texture.
Arrowroot flour: Your go-to for thickening the sauce quickly and naturally; it keeps the finished noodles velvety rather than gloopy.
Poultry seasoning: An aromatic blend (like Frontier brand) that brings an herby, savory backbone to the sauce, without adding any actual poultry.
Minced garlic: Essential for a flavorful, fragrant punch in every bite.
Sea salt: Brightens all the other flavors—don’t forget to season generously!
White onion: Chopped small for a lovely, sweet base that melts into the sauce.
Red pepper flakes: The “spicy” in Spicy Spaghetti Squash Noodles—adjust for your perfect level of tingle.
Paprika: Adds earthiness plus a warm, subtle smokiness that balances the heat.
Cooked spaghetti squash: The star of the show, with long, golden strands that mimic noodles (see notes below if you’re new to roasting spaghetti squash).
Canned tuna (or salmon/chicken): For extra protein and a satisfying, savory finish—feel free to use your favorite.

How to Make Spicy Spaghetti Squash Noodles

Step 1: Sauté Aromatics

Start by heating a drizzle of olive oil in your favorite fry pan over medium heat. Toss in those chopped white onions and let them sizzle until golden and slightly softened, letting their natural sweetness set the stage. This simple step builds a savory base that makes the entire dish sing.

Step 2: Build the Coconut Sauce

Next up, layer in the flavor by adding the coconut milk, poultry seasoning, minced garlic, sea salt, red pepper flakes, and paprika to your sautéed onions. Stir it all together and bring the mixture to a gentle boil. Once it bubbles, drop the heat to a simmer and let it cook for about 3 to 5 minutes—just enough to mingle all the spicy, savory goodness.

Step 3: Thicken with Arrowroot

Slowly sprinkle the arrowroot flour right into your sauce while whisking constantly. Watch the sauce transform before your eyes—smooth, glossy, and thickened just enough to coat those beautiful strands of squash. Pull it off the heat before it gets too thick; nobody wants a gummy sauce!

Step 4: Combine with Squash and Tuna

Now comes the magic: Add your cooked spaghetti squash “noodles” and the drained canned tuna (or salmon or chicken, if that’s your vibe) straight to the pan. Gently toss everything to coat the squash completely in the spicy coconut sauce. As you stir, the noodles get creamy and perfectly spiced, absorbing all the flavor and color.

Step 5: Taste and Serve

Don’t forget to do a taste check! Sprinkle more red pepper flakes or salt if you’re feeling bold. Serve your Spicy Spaghetti Squash Noodles warm, letting the crowd swoon over the creamy, savory, and subtly spicy sauce clinging to each strand.

How to Serve Spicy Spaghetti Squash Noodles

Garnishes

Give your bowl a little flair! Sprinkle chopped fresh herbs like cilantro or parsley over the top for a pop of color and freshness. Toasted sesame seeds or a drizzle of extra coconut milk can add extra richness, while an extra pinch of red pepper flakes brings even more signature spice.

Side Dishes

Spicy Spaghetti Squash Noodles pair beautifully with a crisp, simple green salad dressed in lemon vinaigrette or a platter of roasted vegetables. If you want to round out the meal, try serving alongside steamed broccoli or sautéed greens for color and crunch.

Creative Ways to Present

Go beyond the bowl! Serve your noodles in the hollowed-out spaghetti squash shell for a rustic, Instagram-worthy presentation. You can also portion them into small ramekins for a dinner party, or pile onto a plate with extra protein on the side for a more substantial meal.

Make Ahead and Storage

Storing Leftovers

If you have extra Spicy Spaghetti Squash Noodles, simply transfer them to an airtight container and refrigerate. They’ll keep well for up to three days—the flavors get even more delicious as they marry overnight.

Freezing

These noodles freeze surprisingly well! Let them cool completely before packing into single-serve containers. Freeze for up to one month, then thaw overnight in the refrigerator when the craving hits.

Reheating

To reheat, pop them into a saucepan over medium-low heat or microwave gently, adding a splash of water or coconut milk to bring the sauce back to its original creaminess. Stir occasionally for even warming, and garnish again before serving.

FAQs

Can I use a different protein in Spicy Spaghetti Squash Noodles?

Absolutely! This recipe is fantastic with canned salmon or shredded cooked chicken if you don’t have tuna on hand. It’s even tasty with cooked shrimp or tofu for a pescatarian or vegetarian option.

How do I cook spaghetti squash for this recipe?

Slice your squash in half lengthwise, scoop out the seeds, and roast cut-side down at 400°F for about 40 minutes until tender. Let cool, then rake a fork through the flesh to create long, noodle-like strands.

Can I make Spicy Spaghetti Squash Noodles less spicy?

Of course! Simply reduce the amount of red pepper flakes or use a mild paprika. You’re completely in control of the heat level, so it’s easy to adjust for kids or spice-sensitive eaters.

Is there a substitute for arrowroot flour?

Cornstarch or tapioca flour make great stand-ins for thickening the sauce. Just remember to adjust the amount slightly—start with half as much cornstarch, since it thickens more aggressively than arrowroot.

Can I prepare the sauce ahead of time?

Yes, you can make the coconut sauce a day in advance and store it in the fridge. When you’re ready to serve, reheat the sauce gently, then toss with fresh spaghetti squash noodles and your protein of choice.
