Ingredients
- 2 cups leftover roasted vegetables (e.g., bell peppers, zucchini, eggplant, carrots)
- 1 cup fresh basil leaves, packed
- 1/2 cup fresh flat-leaf parsley
- 1/3 cup toasted pine nuts (or walnuts for earthier flavor)
- 2 cloves garlic, peeled
- 1/2 cup freshly grated Parmesan cheese
- 2 tablespoons freshly squeezed lemon juice
- 1/2 teaspoon red chili flakes, optional for a touch of heat
- 1/2 cup extra virgin olive oil, plus more for drizzling
- Salt and freshly ground black pepper, to taste
- 12 oz pasta (fusilli, penne, or spaghetti work well)
- 1/4 cup toasted pine nuts, for garnish
- Fresh basil leaves, for garnish
Instructions
- Cook the pasta: Bring a large pot of salted water to a boil. Add your chosen pasta and cook until al dente according to package instructions. Reserve 1 cup pasta water, then drain the pasta and set aside.
- Prepare the pesto base: In a food processor, combine the leftover roasted vegetables, fresh basil, parsley, toasted pine nuts, garlic, Parmesan cheese, lemon juice, and red chili flakes (if using). Pulse until coarsely chopped.
- emulsify the sauce: With the processor running on low speed, slowly pour in the olive oil. Continue blending until the mixture turns into a smooth, creamy pesto. If the pesto feels too thick, add reserved pasta water one tablespoon at a time to achieve the perfect consistency.
- Adjust seasoning: Taste and season with salt and freshly ground black pepper. Blend briefly again to incorporate.
- Toss pasta and sauce: Transfer the cooked pasta to a large bowl. Pour the pesto over the pasta and gently toss to coat evenly. add a splash more pasta water if needed to loosen the sauce and help it adhere to the noodles beautifully.
- Serve immediately: Divide the pasta among serving bowls. Garnish with extra toasted pine nuts and fresh basil leaves. Drizzle a little olive oil on top for an inviting glossy finish.
Tips for Success
- Choosing herbs: Fresh basil is classic, but mixing in parsley or even a handful of arugula can brighten and add depth to the pesto.
- Nut swaps: Pine nuts bring a buttery nuance, but walnuts, almonds, or even pistachios create exciting, distinct flavors.
- Veggie varieties: Versatility is key. Use any blend of sweet, earthy, or smoky roasted vegetables for unique flavor profiles each time.
- Make-ahead magic: Prepare the pesto a day ahead; store it in an airtight container with a thin layer of olive oil on top to preserve its vibrant color.
- Adjusting creaminess: Incorporate a spoonful of ricotta or soft goat cheese into the pesto for a luscious, creamy twist.
Serving Suggestions
The vibrant leftover veggie pesto pasta shines best alongside a crisp green salad tossed with lemon vinaigrette, or warm garlic bread to soak up every bite of sauce. For a hearty meal, add grilled chicken or pan-seared shrimp atop. A light sprinkle of extra Parmesan and a few cracked pepper flakes finish the dish beautifully, enticing the eyes before the first forkful.
