This zesty tuna and tomato pasta turns basic cupboard items into a lively, Mediterranean-style dinner that's ideal for quick weeknights. The lush tomato sauce, spotted with tangy olives and capers, coats every strand of pasta while flaky tuna adds hearty protein.
I whipped up this dish one crazy week when my fridge was bare but friends were coming over. What began as a desperate pantry raid has turned into one of my go-to meals that everyone asks for, showing that sometimes the simplest ingredients make the most awesome dinners.
Ingredients
- Penne rigate pasta: Those little grooves grab onto the chunky sauce so well
- Extra virgin olive oil: Don't skimp here, a nice oil makes all the difference
- Brown onion: Adds a lovely sweetness that works against the tangy tomatoes
- Garlic: Go for whole cloves you crush yourself for way better taste
- Parsley stalks: Most folks throw these away but they pack tons of flavor for the sauce
- Red chili flakes: Put in as much or little as you want
- Tinned crushed tomatoes: The heart of our sauce, grab Italian ones if you can
- Tuna in olive oil: The oil brings extra flavor, try to get sustainably caught
- Dried oregano: Gives that classic Mediterranean taste
- Baby capers: Tiny but mighty flavor boosters with a salty zing
- Kalamata olives: Their bold taste and chunky feel make the sauce special
- Fresh flat leaf parsley: Adds color and freshness
- Pasta water: This starchy gold helps create a smooth, clingy sauce
- Lemon wedges: A squeeze at the end wakes up all the flavors
Step-by-Step Instructions
- Get your pasta water going:
- Put lots of water in a big pot and bring it to a full boil. Add salt only after it's boiling to keep your pots nice and stop them from getting damaged while making sure your pasta tastes good all the way through.
- Start your flavor base:
- Warm up olive oil in a big, deep pan over medium-high heat. Toss in onion, parsley stems and chili flakes, letting them cook slowly for 4-5 minutes until onions turn clear and slightly golden. This slow cooking brings out their natural sweetness.
- Throw in the garlic:
- Add your finely chopped garlic to the pan and cook just 1-2 minutes until you can smell it. Watch it carefully because burnt garlic turns bitter fast and can ruin everything.
- Make your sauce:
- Dump in the crushed tomatoes and drained tuna. To get every bit of tomato goodness, pour about ¼ cup water into the empty cans and add that too. Break up any big tuna chunks with your spoon so it spreads out better. Sprinkle in dried oregano, then let everything bubble gently for 15-20 minutes, stirring now and then so nothing sticks as the sauce gets thicker and flavors mix together.
- Boil your pasta:
- While the sauce cooks, drop pasta into the boiling salted water, stirring right away so it doesn't stick. Cook until it's just firm to the bite, usually 1-2 minutes less than what the box says. Before you drain it, scoop out at least a cup of the cooking water.
- Add the finishing touches:
- Mix olives, capers and fresh parsley into the sauce with a gentle stir to warm them up. Adding them late keeps their unique textures and bright flavors intact.
- Mix pasta and sauce:
- Put drained pasta straight into the sauce pan instead of pouring sauce over pasta. Toss everything together, adding splashes of saved pasta water until the sauce turns silky and sticks to every bit of pasta.
- Get it on the table:
- Give it a taste and add salt or pepper if needed. Serve right away with a pinch of fresh parsley on top, a little drizzle of good olive oil, and lemon wedges on the side for everyone to squeeze over their own helping.

The capers might look tiny but they're actually my hidden weapon in this meal. Their salty burst brings unexpected freshness that balances the rich sauce. My mom always put them in her tuna pasta and now when my kids smell their tangy scent, they know dinner's ready.
Make It Your Own
This dish works great with whatever you've got in your pantry. If you're out of penne, any short pasta does the job, like bow ties, shells, or tubes. For folks who can't eat gluten, just swap in your favorite gluten-free pasta, but follow the cooking time on the package and be ready to add extra pasta water at the end since gluten-free kinds tend to soak up more liquid.
You can make it as spicy as you want. If you love heat, throw in twice the red pepper flakes or add a chopped fresh chili with the garlic. For a kid-friendly version, cut back or skip the chili flakes completely and let everyone add their own at the table.
Storage and Reheating
While this pasta shines brightest fresh off the stove, it keeps surprisingly well. Store leftovers in a sealed container in the fridge for up to three days. When warming it up, add a tiny splash of water before heating gently in a covered pan or microwave to bring back the sauce's smoothness.
If you want to keep it longer, freeze just the sauce without pasta in meal-sized containers for up to two months. Let it thaw in the fridge overnight, then warm it in a pan while cooking fresh pasta. Mix them together as the recipe says with plenty of pasta water for the right texture.
Mediterranean Roots
This meal draws from south Italian seaside cooking, where seafood and tomatoes are everyday foods. Back in the day, folks made these pasta dishes out of need, using stored items like canned fish and tomatoes when fresh stuff wasn't around. The olives, capers, and chili flakes show off the bold Mediterranean style that values simple but good ingredients mixed together thoughtfully.

Frequently Asked Questions
- → Can I swap tinned tomatoes for fresh ones?
Sure thing! Fresh tomatoes work, but you’ll need to boil, peel, and crush them to get a smooth sauce. Tinned ones are just quicker and easier to handle.
- → What kind of tuna is best?
Tuna in olive oil adds a rich flavor that's hard to beat. Using brine or water-packed tuna? Drain it well to avoid extra liquid.
- → Is this recipe gluten-free friendly?
Definitely! Just swap in gluten-free pasta. Keep some extra pasta water on hand since gluten-free options can soak up more sauce.
- → How do I dial up or down the spice?
Want extra kick? Throw in more chili flakes. If you’d prefer less heat, cut back on them or leave them out altogether for a mild taste.
- → Can I store the sauce for later?
Yep! This sauce freezes like a dream. Use an airtight container and keep it for up to 2 months. Warm it on the stove when you're ready to enjoy it.
- → Which pasta works well here?
Short pastas like shells, ziti, or penne are great. But if you're in the mood for long noodles, grab linguine or spaghetti.
