Step-by-Step Instructions

Step 1: Roast the Vegetables

Preheat oven to 200°C (400°F). Toss diced vegetables and onion with olive oil, salt, pepper, and Italian herbs. Spread on a baking sheet and roast for 20–25 minutes until caramelized, stirring halfway through.

💡 Tip: Roast vegetables evenly by cutting into uniform pieces.

Step 2: Prepare the Tomato Sauce

In a saucepan, heat olive oil over medium heat. Add minced garlic and sauté until fragrant. Add crushed tomatoes, dried herbs, salt, pepper, and chili flakes. Simmer for 10 minutes, stirring occasionally.

Step 3: Cook the Spaghetti

Cook spaghetti according to package instructions until al dente. Drain and set aside, reserving ½ cup of pasta water.

Step 4: Combine Sauce and Vegetables

Add roasted vegetables to the tomato sauce and stir. If needed, add reserved pasta water to loosen the sauce.

Step 5: Serve

Toss spaghetti in the sauce until coated. Serve hot, garnished with fresh basil and optional nutritional yeast or vegan parmesan.
