I tried making a cold pasta salad yesterday for lunch at work, but it came out kind of bland even though I'd added salt. How much pasta do you use compared to the vegetables and dressing? And is it better to dress the pasta while it's still hot or wait for it to cool down?
It's not really a matter of pasta quantity! In my opinion, the problem isn't having too much pasta and too few vegetables, but rather that cold pasta is a ruthless sponge that absorbs all the dressing and then holds onto it, so it ends up seeming dry and bland. Whoever tells you to dress it while it's hot is right, but there's a detail that makes a huge difference: you need to pour the dressing (oil, vinegar, salt) directly onto the pasta while it's still steaming, right there in the colander, and mix it well before letting it cool down. That way it gets absorbed when the pasta is porous and receptive, instead of waiting for it to solidify.
Then when it's cold, you add the vegetables and more dressing if you need it! The trick nobody mentions is to dress the vegetables separately too with a bit of salt and lemon or vinegar at least 10-15 minutes ahead, so they themselves release a little juice that contributes to the overall flavor. And honestly, for cold pasta salad I use a ratio like two-thirds pasta and one-third mixed vegetables, but the thing that really changes everything is generous dressing right from the start while it's hot. The oil and vinegar need to be a little more than you'd use for a hot dish, because cold pasta absorbs them and if you don't overdo it a bit it stays really bland!
The problem is that cold pasta absorbs the dressing much less than hot pasta, so you need to go a bit overboard with oil, salt, and vinegar compared to what you'd normally do. I usually use a ratio like 2 parts pasta to 3-4 parts vegetables (by weight), so the pasta doesn't dominate the dish. But the most important thing is to dress the pasta while it's still steaming, right after you drain it. That's when it really absorbs the salt and dressing, otherwise it stays bland.
Here's what I do: I drain the pasta, put it in a large bowl with a good glug of extra virgin olive oil, some salt, vinegar (or lemon), and maybe crushed garlic if I feel like it. I let it cool down like that, already dressed. Meanwhile I prep the vegetables and chop them up. When it's cold, I mix everything together and taste it: I almost always have to add a bit more oil because the pasta seems to "drink" it all up. Try not to be shy with the dressing - people tend to use way too little in these salads.
Cold pasta salad needs pretty generous dressing, that's true, but the real trick is dressing it right after you drain it, while it's still hot: it soaks everything up better and picks up more flavor. Then let it cool down naturally - actually, pull the pasta out of the pot a minute before it's perfectly cooked, so it doesn't get mushy once it's cold. As for the pasta-to-vegetables ratio, I never go below 40-45% pasta relative to the total, because otherwise it gets too light. And here's the genius move: add a tablespoon or two of mayo (or sour cream if you prefer) mixed into the base dressing - it doesn't feel "heavy," but it creates a kind of coating that holds all the flavors together nicely, and the salad stays good even the next day.
When you dressed it, was the pasta still steaming hot or already cold from the fridge?
Because the others have a point: cold pasta absorbs way less dressing compared to when it's lukewarm. But the real game changer is adding the dressing in two stages. Right after draining, when the pasta is still hot (and here oil, vinegar, salt work perfectly together), and then again right before eating, once the fresh ingredients have absorbed some of the liquids. That way you make up for the "dry" nature of cold pasta.
For proportions: a rule that works is putting vegetables and dressing in amounts almost equal to the weight of the pasta, not the other way around. If you use 300g of pasta, you should have at least 250-300g of "wet" stuff (tomatoes, cucumbers, olives, maybe some onion). And here's the trick nobody mentions: add a splash of fresh lemon juice on top of the vinegar. It makes all the difference, because the pasta absorbs the acids and doesn't taste flat. Plus salt and pepper should be double what you'd use in a hot dish, because cold kind of dampens your taste receptors.
