Pesto Pasta with Grilled Tuna and Green Beans is a vibrant, Mediterranean-inspired dish that combines the aromatic, herby goodness of pesto with the richness of grilled tuna and the crispness of green beans. This dish offers a perfect balance of textures and flavors, with the creamy, herbaceous pesto complementing the smoky tuna and the fresh green beans, creating a satisfying and healthy meal that’s both light and indulgent.
The base of this dish is pasta, typically spaghetti or any pasta of your choice, cooked al dente. The pasta is then tossed in a generous amount of pesto sauce, made from fresh basil, garlic, pine nuts, Parmesan cheese, and olive oil. The pesto brings a burst of bright, herbal flavor that coats the pasta beautifully.
The star of the dish is the grilled tuna. Fresh tuna steaks are seasoned simply with salt, pepper, and a touch of olive oil before being grilled to your preferred doneness. The tuna adds a smoky, meaty element to the dish, offering a rich contrast to the fresh, herbaceous pesto. Grilling the tuna enhances its natural flavor, giving it a slightly charred exterior and a tender, juicy interior.
Green beans are lightly blanched or sautéed, adding a crisp texture and a pop of color to the dish. Their slight bitterness provides a lovely contrast to the richness of the pesto and tuna, while also adding a refreshing crunch.
Once everything is prepared, the grilled tuna is sliced and placed atop the pesto-coated pasta, with the green beans tossed in for added freshness and texture. A sprinkle of Parmesan or extra pine nuts can be added for extra richness, or a drizzle of lemon juice for a touch of brightness.
Pesto Pasta with Grilled Tuna and Green Beans is a perfect dish for a light summer dinner, a weekend meal, or when you want something that’s both filling and refreshing. The combination of fresh ingredients, smoky tuna, and aromatic pesto makes it an irresistible choice.
In summary, this dish is a harmonious blend of tender pasta, grilled tuna, and crisp green beans, all brought together with a fragrant, creamy pesto sauce. It’s a perfect balance of flavors and textures, making it a go-to for seafood lovers looking for a fresh and satisfying meal.

I didn’t have parmesan, so I used cheddar instead. Not sure if that was a good idea.
Meh. Pasta felt bland, I add some hot sauce for flavor.
This dish is amazing! The grilled tuna adds such a nice touch.
I tried it but the pesto was too garlicky for my taste. Maybe cut back on the garlic?
Wow, I never woulda thought to put tuna with pasta. Genius! My family loved it.
I’m glad you enjoyed it! Tuna and pasta really do make a great combo. Did you add any extra spices?
Tuna with pasta? Really? Seems kinda weird to me. I think I’d stick to regular sauce.
