Fresh basil (1 handful + sprigs for garnish): Adds fresh, aromatic herbal flavor that brightens the entire dish.
Pasta (10 oz): Your choice of pasta, cooked al dente to perfectly hold the creamy sauce.
Reserved pasta water (1–2 tbsp): Helps to loosen the sauce and ensure it clings beautifully to the pasta.
Chili flakes (optional): Adds a gentle heat for those who enjoy a spicy kick.

Instructions

Preheat and prepare vegetables for roasting: Set your oven to 425°F to ensure a high roasting temperature that caramelizes the vegetables. Arrange cherry tomatoes, bell peppers, mushrooms, zucchini, onion, and a whole trimmed garlic head on a baking sheet. Drizzle with olive oil and sprinkle Italian seasoning, salt, and black pepper to evenly coat. Roasting at this temperature for 25–30 minutes softens the veggies and concentrates their flavors, building the sauce’s richness.
Roast vegetables until tender and charred: Roast the vegetables until they become tender and develop light charring, which adds smoky flavor and depth. The roasting transforms raw vegetables into a sweet and savory base that makes this pasta uniquely flavorful.
Blend roasted vegetables into creamy sauce: Once the vegetables cool slightly, squeeze the softened garlic cloves out of their skins into a blender. Add all roasted vegetables along with vegan cream cheese, tomato paste, and fresh basil. Blend until smooth and creamy, allowing the garlic and herbs to infuse the sauce with vibrant flavor. Adjust seasoning with salt and pepper to taste.
Cook pasta to al dente and reserve water: Boil your pasta according to package instructions until al dente, which means tender but still firm to the bite. Before draining, save 1 to 2 tablespoons of pasta cooking water. This starchy water helps loosen and bind the sauce to the pasta for a silky texture.
Combine sauce and pasta: Heat the creamy sauce gently in a pan over medium heat to warm through without breaking. Add the cooked pasta and toss gently to combine, coating every piece evenly. Use the reserved pasta water to adjust sauce consistency as needed, creating a luscious finish that clings perfectly.
Plate and garnish: Serve the pasta hot, topped with fresh basil leaves for an herbal lift. If you prefer a bit of heat, sprinkle chili flakes to taste. This final garnish enhances the dish’s aroma and adds complexity to each bite.
