Roasted eggplant, caramelized onions, fresh tomato sauce and a hint of sherry vinegar combine to make this late-summer pasta dish truly fantastic. //

I don’t know about you, but I’m up to my eyeballs in eggplants here. My CSA delivery last week could have fed a small village, and I’m still feeling a little overwhelmed. Overwhelmed in a good way though. I mean, I’ve been eating my way though a very delicious eggplant chapter in Chez Panisse Vegetables, so far delighting in eggplant gratin with tomato and onion, and roasted eggplant and tomato pizza. I know, it’s been rough.

But this pasta. Oooooh, this pasta. This pasta recipe unexpectedly has eclipsed its chapter companions, its deliciousness attributed to perfectly ripe eggplant, the freshest tomato sauce, sweet basil, caramelized onions, and above all to a most unsuspecting ingredient: sherry vinegar. I don’t know how just a splash of anything could so transform a dish, giving it a depth of flavor that subtly persists through layers of tomatoes and eggplant and onions, but somehow the sherry vinegar has.

There’s something, too, about the way the roasted eggplant melds with the caramelized onions and the tomato sauce that makes cheese totally unnecessary. No cheese on pasta, you ask? Hogwash, you shout!  I mean it. This roasted eggplant tomato sauce spiced with crushed red pepper flakes and freshened with basil was enough for me. I even had some homemade ricotta in the fridge. I even had a bowl of freshly grated Parmigiano Reggiano sitting inches from my plate throughout dinner. I had no trouble refraining.

While I know a bowl of hot pasta perhaps isn’t crossing your mind very often in late summer, eggplants are reaching their peak right about now, and they are oh so good. Give this recipe a go. It’s a keeper for sure.

Finally, if you like summer pastas, you will love this orecchiette with Quick Sautéed Cherry Tomato Sauce.

Caramelized Onion, Tomato, and Eggplant Pasta

Save Recipe



  • 1 to 2 globe eggplants, to yield about 4 to 6 cups of diced eggplant
  • olive oil
  • 1 onion, peeled and thinly sliced (about 2 cups sliced)
  • 2 cloves garlic, minced
  • 1 handful basil leaves
  • kosher salt
  • 3/4 lb. pasta such as Gemelli or whatever you like best
  • sherry vinegar
  • 2 cups tomato sauce (I like this tomato-basil sauce or Marcella Hazan’s Tomato Sauce)
  • red pepper flakes
  • ricotta salata cheese (or grated Parmigiano Reggiano over top)


  1. Preheat the oven to 400ºF. Cut the eggplants into cubes about 3/4-inch square, toss them lightly with olive oil and spread them out in a single layer on a sheet pan. Roast in the oven for 25 minutes or so, until the eggplant is brown and tender.
  2. Put a large (or small) pot of water on to boil for the pasta. Add a large pinch of kosher salt. Cook the pasta al dente.
  3. Meanwhile, heat a large sauté pan with the olive oil and onions over medium heat. Season with salt and sauté the onions until just caramelized, about 20 minutes to 25 minutes. Add the garlic and cook for a moment more, and then deglaze with a splash of sherry vinegar. Add the eggplant, tomato sauce, and a pinch of red pepper flakes. Heat the sauce to simmering. Drain the pasta, add it to the tomato sauce pan, and toss gently. Chiffonade the basil and add it the pan.
  4. Serve the pasta with the ricotta (or Parmigiano Reggiano) crumbled over the top.
