Ingredients

• 12 oz pasta (penne, fusilli, or farfalle work best)
• 1 zucchini, sliced
• 1 red bell pepper, chopped
• 1 yellow bell pepper, chopped
• 1 cup cherry tomatoes
• 1 small red onion, sliced
• 3 cloves garlic, minced
• 3 tablespoons olive oil
• Salt and black pepper to taste
• ½ teaspoon dried oregano
• ½ teaspoon dried thyme
• ½ cup basil pesto (store-bought or homemade)
• ¼ cup grated Parmesan cheese
• Juice of ½ lemon
• Fresh basil leaves for garnish

Instructions

1. Preheat the oven
   Set your oven to 425°F (220°C) and line a large baking sheet with parchment paper.
2. Prepare the vegetables
   Place the zucchini, bell peppers, cherry tomatoes, red onion, and garlic onto the baking sheet. Drizzle with olive oil and season with salt, pepper, oregano, and thyme. Toss everything to coat evenly.
3. Roast the vegetables
   Roast for 20–25 minutes, stirring halfway through, until the vegetables are tender and slightly caramelized.
4. Cook the pasta
   While the vegetables roast, bring a large pot of salted water to a boil. Cook the pasta according to package instructions until al dente. Reserve ½ cup of pasta water, then drain.
5. Combine pasta and pesto
   Return the drained pasta to the pot. Add the pesto and a splash of reserved pasta water to loosen the sauce. Stir until the pasta is evenly coated.
6. Add roasted vegetables
   Gently fold the roasted vegetables into the pasta, ensuring everything is well mixed.
7. Finish the dish
   Add lemon juice and grated Parmesan cheese. Toss again and adjust seasoning if needed.
8. Serve and garnish
   Serve warm, topped with extra Parmesan and fresh basil leaves.

Tips for Perfect Roasted Vegetable Pesto Pasta

1. Don’t overcrowd the pan
Spread vegetables in a single layer. Overcrowding causes steaming instead of roasting, which reduces flavor.

2. Use high heat
Roasting at a high temperature helps caramelize the vegetables, enhancing their natural sweetness.

3. Salt your pasta water well
It should taste like the sea. This step is essential for flavorful pasta.

4. Reserve pasta water
This starchy liquid helps emulsify the pesto, creating a silky sauce that clings to the pasta.

5. Add pesto off heat
Avoid overheating pesto, as it can dull its fresh flavor and vibrant green color.

This dish is excellent for meal prepping. Here’s how to store it properly:

• Refrigerator: Store in an airtight container for up to 4 days

For best results, store the pesto separately and mix just before serving.
