Last week I made walnut pesto and served it with grilled zucchini strips as a last minute appetizer. I’m talking extremely casual–we stood there next to the sink, gobbling down grilled zucchini with huge dollops of pesto, eating it right out of our hands. No plate, but we did need napkins! The combo was so yummy no one cared, and besides, what’s a little savage eating among close friends?

Adding pasta, I turned the pesto and grilled zucchini into an easy dinner. Grilled zucchini and lemony walnut pesto pair well, pasta or no pasta, gluten free pasta or spiralized zucchini zoodles coated with lemony walnut pesto sauce.

Do it:

While the grill heats up, get out the food processor and make the sauce. Finely chop walnuts with shallots, lemon zest and thyme, stir in fresh-squeezed lemon juice and walnut and/or olive oil. Easy. Set that aside.

Next, slice the “zukes” lengthwise into wide thin ribbons. Toss with olive oil and salt and pepper. Pop them on the grill.

Just before you’re ready to eat, cook the fettuccine in plenty of boiling salted water, until the pasta is al dente, tender to the tooth. Stir a bit of pasta water into the pesto to loosen it up, and then toss everything together. This super simple supper is just fancy enough to serve to company.

Grilled Zucchini Fettuccine with Walnut Pesto recipe notes:

  • Walnut pesto marries well with other lightly grilled veggies, all kinds, you name them—eggplant, corn, shiitake mushrooms, asparagus, and red onion, as well as the omnipresent zucchini.
  • I used an inexpensive hand-held mandoline slicer to cut 1/8-inch thick zucchini ribbons. If you want to make “zoodles”, use a spiralizer, like this one. See how to cut veggies into noodles in this roasted asparagus and sweet potato noodle recipe.
  • Delallo fettuccine, which doesn’t contain eggs, keeps this recipe vegan.
  • You might want to try this easy basil walnut pesto with pasta and grilled veggies too.
  • Loosely adapted from a recipe torn from Food & Wine Magazine in 2010.

Walnut pesto:
  • 1 shallot , cut in 4 pieces

  2. On a vegetable grilling accessory tray, grill over high heat, turning until lightly charred on the edges and limp tender, 5 to 10 minutes. Transfer to a plate and keep warm.
  3. Cook the pasta in well-salted water, following to package directions. When the pasta is almost done, mix about 3 tablespoons of the pasta water into the walnut pesto.
  4. Drain the pasta and immediately toss with the walnut pesto and grilled zucchini.
  5. Serve hot, with a sprinkle of thyme and basil leaves.
