Ingredients You’ll Need
Gathering these ingredients is a breeze, and each one plays a key role in building the flavor, texture, and freshness of this dish. From the silky spaghetti to the punchy capers, every component is essential for that balanced experience you’ll come back to again and again.
- 12 ounces spaghetti: The foundation of the recipe, perfectly al dente to hold the sauce.
- 2 tablespoons olive oil: Adds richness and helps meld all the flavors beautifully.
- 3 cloves garlic, minced: Garlic infuses the dish with aromatic depth and warmth.
- 1/4 teaspoon red pepper flakes (optional): Just a hint of heat to awaken the palate.
- 1 (5-ounce) can tuna in olive oil, drained and flaked: Provides a hearty, savory protein boost with excellent texture.
- 2 tablespoons capers, drained and rinsed: These bring a tangy, salty pop that cuts through the richness.
- 1/2 cup cherry tomatoes, halved (optional): Brightens the dish with juicy sweetness and color contrast.
- Zest and juice of 1 lemon: Offers freshness and a zesty lift that makes every bite sing.

- Grated Parmesan cheese for serving (optional): A savory, nutty finishing touch if you like a little extra indulgence.
How to Make Spaghetti with Tuna and Capers Recipe
Step 1: Cook the Spaghetti
Start by bringing a large pot of salted water to a rolling boil. Add the spaghetti and cook it according to the package instructions until it’s just al dente — that perfect tender bite. Be sure to save about half a cup of the pasta cooking water before you drain the noodles, as it will help create a silky sauce later on.
Step 2: Sauté Garlic and Red Pepper Flakes
While your pasta cooks, heat olive oil in a large skillet over medium heat. Toss in the minced garlic and red pepper flakes if using, and cook them gently for about one minute. The key here is to release all that fragrant aroma without burning the garlic, so keep an eye on the color. This step builds the flavorful base of your sauce.
Step 3: Add Tuna and Capers
Next, incorporate the tuna and capers into the skillet. Stir gently to combine, allowing the warm olive oil from the tuna and the briny capers to mingle with the garlic-infused oil. The tuna will flake easily and soak up the flavors, creating a deliciously hearty component.
Step 4: Introduce Cherry Tomatoes (If Using)
If you’re including cherry tomatoes, now is the time to add them. Cook for 2 to 3 minutes until they soften slightly, releasing some of their natural juices. This adds a subtle sweetness and a splash of color that brightens the whole dish.
Step 5: Combine Pasta and Add Lemon
Toss your cooked spaghetti into the skillet along with the lemon zest and juice. Stir everything together carefully, using the reserved pasta water a little at a time to loosen the sauce and ensure it clings to every strand. This is where the magic happens—the acidity of the lemon balances the savory tuna and salty capers perfectly.
Step 6: Season and Finish with Parsley
Season generously with salt and freshly ground black pepper to your liking before removing the skillet from heat. Finally, stir in the chopped fresh parsley for a bright herbaceous note. If you enjoy Parmesan, sprinkle some over your serving to add a luscious, creamy dimension.
How to Serve Spaghetti with Tuna and Capers Recipe

Garnishes
The best garnishes for this dish are simple and fresh because the flavors are vibrant on their own. A sprinkle of chopped parsley adds a lovely green pop and freshness, while a little extra grated Parmesan transforms the bowl into a richer, more indulgent experience. Lemon wedges on the side invite anyone to add an extra burst of citrus if desired.
Side Dishes
This pasta shines as a light but satisfying main course, but you can pair it with something crisp and refreshing like a mixed green salad with a lemon vinaigrette to complement the zesty flavors. Crusty bread works wonderfully too, soaking up any leftover sauce. For something heartier, serve alongside roasted vegetables or grilled asparagus for an extra touch of elegance.
Creative Ways to Present
Want to impress your guests? Try twirling individual portions of the spaghetti around a fork into a neat nest on the plate, then drizzle any reserved sauce on top artistically. Presenting it in shallow bowls instead of deep plates highlights the colors and makes it easier to enjoy every bite. Garnish the plate with a few capers and lemon zest curls for a professional touch that elevates this humble recipe into a dinner party delight.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers, store them in an airtight container in the refrigerator. They’ll keep well for up to 2 days. The flavors may deepen with time, but to avoid the pasta becoming too soft, it’s best to enjoy them soon.
Freezing
This dish isn’t the best candidate for freezing because the texture of cooked pasta and capers can change after thawing. For peak freshness, it’s better to make it fresh or refrigerate and consume within a couple of days instead.
Reheating
Reheat spaghetti gently on the stovetop over low heat with a splash of water or olive oil to loosen the sauce and prevent it from drying out. You can also microwave in short bursts, stirring halfway through to warm evenly. Fresh parsley and a squeeze of lemon afterwards will revive the dish beautifully.
FAQs
Can I use fresh tuna instead of canned tuna?
While fresh tuna could be used, this recipe is designed around canned tuna in olive oil for convenience and flavor. Fresh tuna requires different cooking times and techniques, so if you’re craving fresh fish, a seared tuna steak alongside might be a better approach.
What can I substitute for capers if I don’t have any?
If you don’t have capers on hand, chopped green olives work well as a substitute to provide that same briny, salty pop. Just adjust the amount based on your taste preferences since olives can be stronger.
Is this recipe suitable for a pescatarian diet?
Absolutely! The Spaghetti with Tuna and Capers Recipe is a perfect pescatarian meal, combining seafood protein with fresh plant-based ingredients for a well-rounded dish that fits beautifully within that diet.
Can I make this recipe gluten-free?
Yes, simply swap the regular spaghetti for your favorite gluten-free pasta. The rest of the ingredients are naturally gluten-free, so it’s an easy adaptation without sacrificing taste.
How spicy is the dish with the red pepper flakes?
The red pepper flakes add just a subtle kick that gently warms the palate without overwhelming the other flavors. They’re completely optional, so you can omit or increase the amount depending on your spice preference.
Final Thoughts
If you’re craving a delicious, speedy meal that feels both comforting and fresh, this Spaghetti with Tuna and Capers Recipe is absolutely worth trying. It turns simple pantry ingredients into a delightful plate of pasta that tastes like you’ve put in way more effort than just a few minutes. I promise, once you try it, you’ll want to keep this recipe in your rotation for those busy nights when you need something both easy and impressive.
