Instructions

  1. Step 1: Bring a large pot of salted water to a boil and add 12 oz rotini pasta. Cook for 9-11 minutes until al dente, then drain and rinse under cold water to cool.
  2. Step 2: Preheat grill or grill pan over medium-high heat. Toss 1 medium sliced zucchini, 1 large red bell pepper cut into 1-inch pieces, and 1 medium yellow squash sliced lengthwise with 2 tbsp olive oil, 1/2 tsp salt, and 1/4 tsp black pepper.
  3. Step 3: Grill the vegetables for 3-4 minutes per side until tender and slightly charred, then remove and chop into bite-sized pieces.
  4. Step 4: In a large bowl, combine the cooled pasta, grilled vegetables, 1 cup halved cherry tomatoes, and 1/2 cup basil pesto. Toss gently to coat everything evenly.
  5. Step 5: Drizzle remaining 1 tbsp olive oil, sprinkle 1/2 tsp salt and 1/4 tsp black pepper, and toss again.
  6. Step 6: Top with 1/4 cup grated parmesan cheese and 2 tbsp toasted pine nuts before serving cold or at room temperature.

How do I store leftover Grilled Vegetable and Pesto Pasta Salad?

Transfer to an airtight jar and refrigerate for up to 5–7 days. Most sauces freeze well for up to 2 months — portion into small containers or freezer bags so you can thaw only what you need. Stir before serving; cream- or yogurt-based sauces may separate on standing.

Can I substitute ingredients in Grilled Vegetable and Pesto Pasta Salad?

For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Grilled Vegetable and Pesto Pasta Salad for a different number of people?
