Ingredients
Instructions
- Adjust rack to top position and preheat oven to 450°F. Bring a large pot of salted water to a boil. Wash and dry produce. Cut broccoli into 1-inch pieces if necessary. Zest and quarter lemon. Peel and mince or grate garlic.
- Toss broccoli on a baking sheet with a drizzle of olive oil, salt and pepper. Roast on top rack until browned and crispy, 12-15 minutes.
- Once water is boiling, add spaghetti to pot. Cook, stirring occasionally, until al dente, 9-11 minutes. Reserve ½ cup pasta cooking water (1 cup for 4 servings), then drain.
- While pasta cooks, place 3 tablespoons butter in a small microwave-safe bowl. Microwave until just softened, about 10 seconds. Add lemon zest, half the Parmesan (save the rest for serving), a pinch of garlic and a pinch of chili flakes if desired. Mash with a fork to combine. Season with salt and pepper.
- Rinse shrimp under cold water, then pat dry with paper towels. Toss in a large bowl with a large drizzle of olive oil, remaining garlic, salt and pepper. Heat a large pan over medium-high heat. Add shrimp and cook, stirring occasionally, until opaque and cooked through, 2-4 minutes.
- To pan with shrimp, add drained spaghetti, broccoli, stock concentrate, garlic butter and ¼ cup reserved pasta cooking water (⅓ cup for 4 servings). Toss until everything is thoroughly coated in sauce. Add a squeeze or two of lemon juice to taste. Season with salt and pepper. Divide pasta between bowls and top with remaining Parmesan and a pinch of chili flakes if desired. Serve with any remaining lemon wedges on the side.
Recipe Tips
For extra flavor, use freshly grated Parmesan.
