Tuna pesto pasta is a creamy, comforting, and flavorful dish that’s simple to prepare. Tender pasta is tossed in a basil pesto–based sauce brightened with lemon and enriched with parmesan and flaked tuna. With just a handful of pantry staples, you can have a satisfying dinner on the table in 30 minutes or less.
This recipe is perfect for busy weeknights when you want something tasty without a lot of fuss. It relies on ready-made pesto and canned tuna, so there’s no need to thaw meat or do extensive prep. The minimal ingredient list makes it economical and convenient—most items are pantry staples you likely already have.
Pesto and tuna are the flavor anchors. Prepared basil pesto brings garlic, basil, and a rich herb aroma, while sun-dried tomatoes add color and concentrated tomato flavor. Fresh lemon juice lifts the dish with acidity, and freshly grated parmesan creates a silky finish that helps the sauce cling to the noodles. The tuna contributes protein and savory depth, making this a well-balanced, satisfying meal.

What You Need to Make Tuna Pesto Pasta
1 lb pasta — any shape you prefer; penne, fusilli, or spaghetti all work well.
1 cup sun-dried tomatoes in oil — the oil adds flavor and helps coat the pasta; chop if you prefer smaller pieces.
2 (5 oz) cans tuna — tuna packed in water keeps the dish from becoming too oily; tuna in oil works too if you prefer a richer result.
1 cup prepared basil pesto — swap for sun-dried tomato pesto for a different twist.
½ cup reserved pasta cooking water — the starchy, salted cooking water loosens the pesto into a silky sauce.
1 lemon, squeezed — fresh lemon brightens the flavors.
½–1 cup parmesan, freshly grated — adds creaminess and helps bring the sauce together.
Pinch red pepper flakes (optional) — for a touch of heat.
What Is the Best Tuna to Use?
Either water-packed or oil-packed tuna will work; choose based on your texture and richness preference. Water-packed tuna keeps the sauce lighter, while oil-packed tuna adds richness. There are two common types: albacore (often labeled “white”) and light tuna (which can include skipjack or other smaller species). Albacore is firmer and milder; light tuna is flakier and typically more flavorful. If sustainability is important, look for pole-caught or “dolphin-safe” labels and BPA-free packaging.
How to Make Easy Tuna Pesto Pasta
Step 1: Bring a large pot of salted water to a boil. Add the pasta and cook according to the package directions.
Step 2: When the pasta is done, turn off the heat and reserve ½ cup of the cooking water. Drain the pasta.
Step 3: Return the pasta to the pot set over low heat. Add the pesto and a few tablespoons of the reserved pasta water, stirring until the pesto loosens and evenly coats the noodles. Add only enough water to create a silky sauce.
Step 4: Gently fold in the drained tuna, sun-dried tomatoes, lemon juice, parmesan, and red pepper flakes (if using). Stir to combine and serve immediately.
Tuna Pesto Pasta Variations
- Add vegetables — stir in spinach, frozen peas, or chopped artichoke hearts for color and nutrition.
- Stir in hummus — a tablespoon or two of lemon-dill hummus can add creaminess and extra flavor.
- Use canned chicken — substitute canned chicken breast if you prefer a non-seafood option.
- Try sun-dried tomato pesto — swap the basil pesto for sun-dried tomato pesto for a tomato-forward flavor.
- Make it creamier — add a splash of heavy cream for a richer sauce.
- Make it gluten-free — use your favorite gluten-free pasta; the rest of the ingredients are naturally gluten-free.
- Add olives — green or Kalamata olives contribute briny depth.
- Turn it into a bake — top with extra parmesan and broil until bubbly for a tuna pesto pasta bake.
What to Serve With Tuna Pesto Pasta
- Simple green beans or a crisp salad to balance the richness
- Roasted vegetables for added texture and color
- Garlic bread or a crusty loaf to mop up the sauce
Storing Tuna Pesto Pasta
Store leftovers in an airtight container in the refrigerator within two hours of cooking. They will keep for up to five days. Reheat in the microwave in short intervals, stirring between bursts, or warm gently on the stovetop with a splash of water to refresh the sauce. Freezing is not recommended, as the pasta texture can change.
