Ingredients You’ll Need

This recipe serves two people and can easily be doubled or tripled. The beauty lies in its simplicity and the use of readily available ingredients.

Spaghetti: 200g. While classic spaghetti is perfect, feel free to substitute with linguine, penne, or fusilli. For a healthier option, use whole wheat spaghetti to add extra fiber.
Canned Tuna: 1 can (around 160g), drained. You can use tuna stored in either oil or water. Tuna in oil can add a little more richness to the sauce, while tuna in water is a leaner option.
Spinach: 75g of fresh spinach. This seems like a lot, but it wilts down significantly. You can also use frozen spinach; just be sure to thaw it and squeeze out all the excess water first.
Garlic: 1 large clove, finely minced or chopped. Garlic is the aromatic heart of this dish. Feel free to add more if you’re a garlic lover.
Chili Flakes or Powder: 1-2 teaspoons, adjusted to your spice preference. This adds a gentle warmth that elevates the entire dish. Start with less and add more if needed.
Olive Oil: A tablespoon for frying. A good quality extra virgin olive oil will add the best flavor, but vegetable oil works perfectly fine too.

–Salt and Black Pepper: To taste. Seasoning is key to bringing all the flavors together.

Optional Add-ins for Extra Flavor:

Parmesan Cheese: A sprinkle of freshly grated Parmesan for serving adds a salty, savory finish.
Lemon: A squeeze of fresh lemon juice or a bit of zest at the end can brighten up the flavors beautifully.
Fresh Parsley: Chopped parsley sprinkled over the top adds a touch of freshness and color.

Step-by-Step Instructions

Follow these simple steps to create a perfect plate of Tuna and Spinach Spaghetti every time. The key is to multitask by preparing the sauce while the pasta cooks.

Cook the Spaghetti: Bring a large pot of water to a rolling boil. Add a generous amount of salt—this is your only chance to season the pasta itself. Add the 200g of spaghetti and cook according to the package directions until it is al dente (cooked through but still with a slight bite). Before draining, reserve about a cup of the starchy pasta water. This water is liquid gold and will help create a silky sauce.
Sauté the Aromatics and Spinach: While the pasta is cooking, heat a tablespoon of olive oil in a large skillet or pan over a low to medium heat. Add the minced garlic and cook for about 30-60 seconds until it becomes fragrant. Be careful not to let it brown or burn, as it will turn bitter. Add the 75g of fresh spinach to the pan. It will look like a huge amount, but keep stirring gently for about 5 minutes until it has completely wilted down.
Incorporate the Tuna and Spices: Once the spinach is wilted, add the drained can of tuna to the skillet. Use a fork to break it up into smaller flakes and mix it with the spinach and garlic. Sprinkle in the chili flakes, salt, and pepper. Continue to cook for another 5 minutes, allowing the flavors to meld together.
Combine Everything: By now, your spaghetti should be cooked. Drain it (remembering to save some pasta water!) and add the hot spaghetti directly into the skillet with the tuna and spinach mixture. Toss everything together thoroughly to coat the pasta with the sauce.
Create the Sauce and Serve: If the pasta seems a bit dry, add a splash of the reserved pasta water. The starch in the water will emulsify with the oil, creating a light, creamy sauce that clings beautifully to every strand of spaghetti. Toss again until you reach your desired consistency. Serve immediately, topped with a sprinkle of Parmesan cheese and fresh parsley if you wish. Enjoy your delicious and healthy meal!

Recipe Variations and Customizations

This Tuna and Spinach Spaghetti is fantastic as is, but it also serves as a wonderful canvas for your culinary creativity. Here are a few ideas to switch things up:

Make it Creamy: For a richer, more decadent dish, stir in a tablespoon of cream cheese, a splash of heavy cream, or a dollop of Greek yogurt into the sauce at the very end.
Add More Vegetables: Bulk up the nutritional content by adding other veggies. Sautéed mushrooms, chopped sun-dried tomatoes, roasted red peppers, or a handful of cherry tomatoes (halved and added with the spinach) would all be excellent additions.
Boost the Flavor Profile: For a briny, Mediterranean twist, add a tablespoon of capers or some chopped black olives to the sauce along with the tuna.
Use a Different Protein: If you’re not a fan of tuna, this recipe works wonderfully with canned salmon or even shredded cooked chicken.
Go Gluten-Free: Simply substitute the traditional spaghetti with your favorite gluten-free pasta. Just be sure to cook it according to the package instructions.

Storage and Reheating

This pasta dish is best enjoyed fresh, but leftovers can still be delicious. Store any remaining pasta in an airtight container in the refrigerator for up to 2 days. To reheat, you can use a microwave or gently warm it in a skillet over low heat. It may become a bit dry, so add a splash of water or a little olive oil to loosen the sauce and bring it back to life.
