Grilled Tomato Pesto Adds A Burst Of Flavor To Your Favorite Pasta

Share on:

For a long time I thought there was only one kind of pesto. What could be better than fresh basil, garlic, parmesan, pine nuts and olive oil? Can anything match the bright, fresh flavor and nuttiness of pesto? But the name pesto has nothing to do with the ingredients of the sauce, it comes from the manner in which it is prepared. In Italian, “pesto” means to “pound” or “crush.”

Originally, pesto was created using a mortar and pestle. So, any sauce made in this manner can be called a pesto. I’ve made pesto with walnuts instead of pine nuts and another using sun-dried tomatoes, which is one of my family’s all time favorites. That led me to wonder if there was a way to use my grill to produce a pesto? And, that’s how I came up with the concept of grilled tomato pesto. It’s a savorier version of my sun dried tomato pesto with smokey overtones thanks to the grill. And, best of all, it can be ready in 30 minutes or less.

  • Add the pasta to a pot of salted water before grilling the tomatoes and put it on stove. Set the burner to a medium high flame to get the water boiling quickly. Pesto is best served as soon as it’s made and you’ll want the pasta finished and waiting for the sauce. Make sure you have plenty of water in the pot, you may need it to get the pesto to correct its consistency.
  • The first step is to prepared the tomatoes. Slice the tomatoes in quarters or fifths lengthwise and remove the locular ribs and seeds.

  • Carefully score the inside of the tomatoes widthwise so they will lay flat on the grill.

  • Preheat the grill to a high temperature and arrange the segments, skin down, in rows across the grill grates. The point is to get a good char on the skin and meat. If the grill is hot this should only take a few minutes.

  • Flip the tomatoes once the skin has a good color and grill the inside. By now the tomatoes will be getting very soft so you will have to be careful getting them off the grill without dropping them through the grates.

  • Take the pine nuts and garlic cloves and toast them lightly in a frying pan on your grill’s side burner over medium flame. If you don’t have a side burner, you can use your stove.

  • Keep the pine nuts and garlic moving in the pan so they don’t burn. Take them off the burner as soon as you see some color.

  • Blend the ingredients finely while slowly adding the olive oil, sugar, salt and pepper. The finished pesto will be a medium thick paste. At this moment the pesto is at its fullest flavor and should be served immediately.

  • The pasta should be taken off the burner when is slightly underdone or “al dente.” Drain the excess water from the pot but reserve it for the next step.
  • Transfer the hot pasta to a large bowl and add the pesto to the bowl. Using two wooden spoons mix the pesto into the pasta. If the pesto is too thick, add a few tablespoons of the pasta water. This water is rich with starch and salt and should help to coat the pasta thoroughly and create a wonderful sauce.
