Bring a pot of salted water to a rolling boil and cook the rotini according to package directions—usually around 12 minutes—until just past al dente. I've learned that slightly overcooked pasta actually works better here because it absorbs the dressing instead of resisting it. Drain the pasta and let it cool for exactly 2 minutes in the colander.

While the pasta is still warm, transfer it to a large mixing bowl and immediately drizzle with half the extra-virgin olive oil and half the fresh lemon juice. This step matters because warm pasta is like a sponge—it'll absorb those flavors deep into each noodle. Toss gently until every strand gets coated, then let it sit for 5 minutes.

Whisk together the remaining olive oil, remaining lemon juice, dried oregano, and black pepper in a small bowl to create the final dressing. The emulsion won't be perfect—and that's actually correct—because we want the acid and oil to stay slightly separated so flavors punch differently as you eat.

Add the halved cherry tomatoes, diced cucumber, and thinly sliced red onion to the pasta bowl, then pour the dressing over top. Fold everything together gently, being careful not to crush the tomatoes or bruise the cucumber pieces. I learned this the hard way when I got too aggressive and ended up with mushy vegetables halfway through.

Fold in the sliced Kalamata olives and the feta cheese cubes last—this is the step that ensures they stay visible and intact rather than disappearing into the pasta. The Greek pasta salad crowd summer recipe looks more impressive when you can see every component. Let everything sit at room temperature for 15 minutes so flavors can start finding each other.

Taste and adjust seasonings with extra lemon juice or oregano if needed. Be honest with yourself here—if it tastes bland on the first bite, add acid, not salt. The Mediterranean disappears fast at cookouts partly because it's perfectly seasoned from the start, not rescued with garnish at serving time.
