Step‑by‑Step Instructions for Spicy Spaghetti Squash Tuna Noodles
Step 1: Preheat and Prep the Squash
Begin by preheating your oven to 450°F (232°C). Carefully slice the spaghetti squash in half lengthwise and scoop out the seeds. Brush the cut sides with olive oil and place them cut side up on a baking sheet lined with parchment paper. This preparation is essential for getting the perfect texture for your Spicy Spaghetti Squash Tuna Noodles.
Step 2: Bake the Squash
Place the baking sheet in the preheated oven and bake the spaghetti squash for about 25 minutes or until the flesh is tender and easily shreds with a fork. The squash should have a slight golden hue, indicating it’s ready to be transformed into noodles. While it bakes, you can move on to preparing the creamy coconut sauce.
Step 3: Sauté the Aromatics
In a medium frying pan, heat two tablespoons of olive oil over medium heat. Once the oil is shimmering, add the chopped white onion and sauté for about 5-7 minutes until it’s golden and translucent. The onions should be fragrant and nicely caramelized, creating a lovely base for your spicy sauce.
Step 4: Combine the Sauce Ingredients
Next, add in the full-fat coconut milk, minced garlic, poultry seasoning, red pepper flakes, and paprika to the sautéed onions. Stir well to combine and bring this mixture to a gentle boil. The coconut milk should bubble lightly, creating a creamy and aromatic sauce that will coat your Spicy Spaghetti Squash Noodles.
Step 5: Simmer the Sauce
Once boiling, reduce the heat to a simmer and cook for 3-5 minutes, allowing the flavors to meld together. Stir occasionally as the sauce thickens slightly, gaining a luxurious consistency. Keep an eye on the sauce—it should remain saucy but not overly thickened at this stage.
Step 6: Thicken the Sauce
Slowly and gradually sprinkle in the arrowroot flour while whisking continuously to prevent clumps. Continue to whisk until the sauce reaches your desired thickness; this should take about 1-2 minutes. Be careful not to overcook the sauce, as it can lose its lovely creamy texture crucial for your Spicy Spaghetti Squash Tuna Noodles.
Step 7: Combine the Ingredients
Once thickened, gently fold the cooked spaghetti squash strands into the creamy sauce along with the drained canned tuna. Mix everything thoroughly to ensure the noodles are well coated with the flavorful sauce. This step brings your Spicy Spaghetti Squash Tuna Noodles together into a cohesive and delicious dish ready for enjoyment.
Step 8: Serve and Garnish
Serve your spicy spaghetti squash tuna noodles immediately, garnished with freshly chopped parsley or green onions for a burst of color and flavor. Enjoy this comforting and nourishing meal, perfect for any weeknight dinner or meal prep session—all in under 30 minutes!

Spicy Spaghetti Squash Tuna Noodles Recipe FAQs
What type of spaghetti squash should I choose for the best flavor?
Absolutely! Look for a spaghetti squash that feels heavy for its size with a smooth, creamy skin. It’s best to avoid squash with dark spots or blemishes, as these can indicate overripeness. A good spaghetti squash has a firm exterior and a nice golden-yellow hue, which signifies ripeness and the right amount of sweetness in flavor.
How should I store leftover Spicy Spaghetti Squash Noodles?
Store leftovers in an airtight container in the refrigerator for up to 3 days. When reheating, add a splash of coconut milk to restore the creamy texture. If you’re planning to use the leftovers, reheat gently on the stove or in the microwave to avoid drying out the noodles.
Can I freeze Spicy Spaghetti Squash Tuna Noodles?
Yes, you can! To freeze, portion the noodles in freezer-safe containers, ensuring they’re cooled completely first. They can be stored for up to 2 months. To reheat, thaw overnight in the fridge, then warm on the stovetop over low heat, adding a bit of water or coconut milk to help maintain moisture.
What if my sauce doesn’t thicken properly?
Very! If your sauce isn’t thickening, ensure you’re whisking in the arrowroot flour slowly while the sauce is simmering. If it still isn’t thickening as desired, you can dissolve a bit more arrowroot in a small amount of cold water and add it gradually to the sauce, stirring continuously until you reach the desired consistency.
Can I make this recipe vegetarian or vegan?
Certainly! To make it vegetarian, simply swap out the tuna for chickpeas or leave it out entirely and add extra veggies like bell peppers or spinach. Using coconut milk keeps it vegan, but you can also experiment with veggie broth for a flavorful base. Enjoy the flexibility!
Is this recipe suitable for pets?
I recommend not sharing this dish with pets. While spaghetti squash can be safe for dogs in moderation, the ingredients like garlic and onion can be harmful to both dogs and cats. Always consult your vet before introducing new foods to your pet’s diet!
