Gathering the right ingredients is the secret to pulling off this flavorful dish. Each element plays its role, from the smooth, rich coconut milk that forms the heart of the sauce to the crisp, spicy notes of red pepper flakes and paprika, creating a harmonious symphony of tastes and textures.

Full fat coconut milk (2 cans or 27 oz): Provides a creamy base with a subtle sweetness that complements the spices perfectly.
Arrowroot flour (2-4 tablespoons): Used as a thickener to give the sauce a luscious, velvety consistency without overpowering the flavors.
Poultry seasoning (2 teaspoons): Adds a warm, herbaceous layer that deepens the savory notes in the sauce.
Minced garlic (2 teaspoons): Infuses the dish with its signature aromatic punch essential for complexity.
Sea salt (2 teaspoons): Enhances all the flavors, making each bite pop just right.
Small white onion (1, chopped): Brings slight sweetness and texture that harmonize beautifully with the spicy sauce.
Red pepper flakes (1/2 teaspoon): Delivers the perfect amount of heat to make your palate tingle.
Paprika (1 teaspoon): Adds smoky warmth and rich color.
Medium cooked spaghetti squash (1): Naturally noodle-like strands that are light, tender, and a great low-carb alternative to pasta.
Canned tuna (6 oz): Offers protein and a savory finish that pairs wonderfully with the creamy sauce.

How to Make Spicy Spaghetti Squash Noodles with Coconut Sauce and Tuna Recipe

Step 1: Prepare the Spaghetti Squash

Start by cutting your spaghetti squash lengthwise and scooping out the seeds with a large spoon. Place the halves face up on a baking sheet, lightly brush them with olive oil, and roast at 450°F for about 25 minutes. The heat transforms the squash, making it tender and perfect for shredding into beautiful spaghetti-like strands with a fork once it cools a bit.

Step 2: Sauté the Aromatics

While the squash is roasting, heat a drizzle of olive oil in a frying pan over medium heat. Toss in the chopped onion and gently sauté until it turns golden and fragrant. This step builds a flavor foundation for your sauce, awakening the senses with sweetness and slight caramelization.

Step 3: Build the Coconut Sauce

Add the minced garlic, poultry seasoning, sea salt, red pepper flakes, paprika, and both cans of full fat coconut milk to the pan with sautéed onions. Stir everything together and bring the mixture to a boil. Then reduce the heat and let it simmer gently for about 3 to 5 minutes, letting the spices meld beautifully into the creamy base.

Step 4: Thicken the Sauce

Sprinkle in the arrowroot flour little by little, whisking continuously to prevent lumps, until the sauce thickens just enough to coat a spoon. Be careful not to overcook at this stage, or the sauce might become too dense. The end goal is a silky, dreamy consistency that clings perfectly to the noodles.

Step 5: Combine Everything

Gently fold in the cooked spaghetti squash strands and canned tuna, mixing until every strand is luxuriously coated with that spicy coconut sauce. The tuna adds a delightful savory texture, balancing the natural sweetness and spice with protein-packed goodness.

Garnishes

A few fresh garnishes can elevate this dish to restaurant-quality presentation. Think chopped fresh cilantro for a herbaceous brightness, thinly sliced green onions for crunch, or a sprinkle of toasted sesame seeds to add a nutty finish. A wedge of lime on the side also complements the coconut and spice beautifully, inviting a little zesty squeeze right before eating.

Side Dishes

Because this is a hearty and satisfying main, lighter sides work best. Consider a crisp green salad with a tangy vinaigrette or some steamed bok choy with a drizzle of sesame oil to echo the Asian-inspired flavors. If you want something with a bit more substance, jasmine rice or cauliflower rice pairs wonderfully, soaking up any extra sauce with ease.

Creative Ways to Present

For a fun twist, try serving the Spicy Spaghetti Squash Noodles with Coconut Sauce and Tuna Recipe right inside the roasted squash halves. It makes a stunning and rustic presentation that’s sure to impress. Alternatively, pile it high in shallow bowls and garnish the edges with fresh chili slices or edible flowers to create a feast for the eyes as well as the taste buds.

Make Ahead and Storage

Storing Leftovers

Leftovers can be stashed in an airtight container in the fridge for up to 3 days. The flavors tend to meld even more overnight, making it a wonderful next-day meal. Just be sure to keep it chilled promptly to maintain freshness.

Freezing

If you want to freeze this dish, it’s best to store the sauce and noodles separately to preserve texture. The sauce freezes well on its own for up to 2 months when kept in a freezer-safe container. Spaghetti squash noodles are best fresh but can be frozen for up to a month if tightly wrapped.

Reheating

Reheat gently on low to medium heat in a skillet or microwave. Stir frequently and add a splash of water or coconut milk if the sauce feels too thick or dry. Avoid overheating to keep the sauce smooth and the tuna tender instead of rubbery.

FAQs

Can I use lite coconut milk instead of full fat?

You can, but the sauce will be thinner and less creamy. To compensate, add extra arrowroot flour gradually until you reach your desired consistency, and expect a slightly lighter mouthfeel.

Is canned tuna the best choice for this recipe?

Canned tuna works wonderfully for convenience and flavor, but feel free to substitute with canned salmon or chicken if you prefer. Each brings a unique twist while maintaining protein content.

How spicy is this recipe? Can I adjust the heat?

The heat is moderate with the controlled amount of red pepper flakes. If you prefer it milder, reduce the flakes or omit them entirely. Craving more spice? Increase the flakes or add fresh sliced chili peppers while cooking.

Can I prepare the spaghetti squash ahead of time?

Absolutely! You can roast the squash a day or two in advance and store the strands in the fridge so it’s ready to toss with the sauce when needed.

What if I don’t have arrowroot flour?

You can substitute cornstarch or tapioca starch, but use a little less to start because they thicken more aggressively. Mix with cold water before adding to the sauce to avoid lumps.
