Instructions

  1. Step 1: Preheat oven to 425°F. Toss 1 medium zucchini (halved lengthwise and sliced 1/2-inch thick), 1 red bell pepper (seeded and chopped into 1-inch pieces), and 1 tsp olive oil on a parchment-lined baking sheet. Season with 1/4 tsp salt and 1/4 tsp pepper, then roast for 20 minutes until edges are caramelized.
  2. Step 2: While vegetables roast, cook 12 oz spaghetti in a large pot of salted boiling water for 8 minutes until al dente; reserve 1/2 cup pasta water before draining.
  3. Step 3: In a medium saucepan, heat 2 tbsp olive oil over medium-low heat. Add 3 minced garlic cloves and 1/4 tsp saffron threads, stirring for 1 minute until fragrant. Add the juice of 1 lemon, 1/2 cup vegetable broth, and the roasted vegetables. Simmer for 3 minutes until sauce thickens slightly.
  4. Step 4: Add drained spaghetti to the saucepan with 1/4 cup reserved pasta water. Toss vigorously for 2 minutes until pasta is evenly coated. Stir in 1/4 cup fresh basil and 1/2 tsp black pepper. Serve immediately with extra basil for garnish.
