About Roasted Vegetable Pesto Pasta

Roasted Vegetable Pesto Pasta is a colorful, wholesome, and satisfying meal packed with oven-roasted vegetables, creamy basil pesto sauce, and perfectly cooked pasta. Roasting naturally caramelizes the vegetables, enhancing their sweetness while creating deep, rich flavors. A light coating of cornflour helps transform the vegetable juices into a silky sauce, which combines beautifully with fresh cream and pesto. This easy vegetarian pasta is perfect for weeknight dinners, meal prep, or entertaining guests.

Instructions

Step 1: Prepare the Vegetables

1. Preheat your oven to 200°C (400°F).

Step 2: Add Remaining Vegetables

1. Add the zucchini, bell peppers, onion, and garlic to the roasting dish.

Step 3: Roast

1. Roast for 25–30 minutes until the vegetables become tender and lightly caramelized.
2. Stir once halfway through for even roasting.

Step 4: Cook the Pasta

1. While the vegetables roast, bring a large pot of salted water to a boil.

4. Sprinkle with Parmesan cheese if using.

Step 7: Serve

Serve immediately, garnished with fresh basil leaves and freshly cracked black pepper.

Why Coat the Tomatoes with Cornflour?

As the vegetables roast, they naturally release moisture. The cornflour combines with these juices, creating a light, silky sauce instead of watery liquid. When the pesto and cream are added later, this naturally thickened vegetable sauce becomes rich, creamy, and packed with roasted flavor, coating the pasta beautifully.

Chef’s Tips

• Roast vegetables in a single layer for the best caramelization.
• Use freshly made basil pesto for maximum flavor.
• Reserve pasta water to adjust the sauce consistency.
• Don’t overcook the pasta—it should remain slightly firm.
• Add spinach during the final mixing for extra nutrition.
• Top with toasted pine nuts for added crunch.

Variations

• Protein Boost: Add grilled chicken, shrimp, or tofu.
• Vegan Version: Replace cream with oat or coconut cream and use vegan pesto.
• Extra Veggies: Mushrooms, broccoli, asparagus, or eggplant work beautifully.
• Spicy Version: Add red chili flakes before serving.
• Cheesy Bake: Transfer to a baking dish, top with mozzarella, and bake until bubbly.
