Instructions

  1. 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 florets into 1-inch pieces if necessary. Zest and quarter lemon. Peel and mince or grate garlic.
  2. 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.
  3. 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.
  4. While pasta cooks, place 3 tablespoons butter (6 tablespoons for 4 servings) 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 small pinch of chili flakes if desired. Mash to combine. Season with salt and pepper.
  5. 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.
  6. To pan with shrimp, add stock concentrate, drained spaghetti, broccoli, garlic butter and ¼ cup reserved pasta cooking water (1/3 cup for 4 servings). Toss until everything is combined and coated in buttery 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 and squeeze lemon juice just before serving.

Be careful not to overcook the shrimp; they should be opaque and firm, about 2-4 minutes.

Reserve more pasta water than you think you need to adjust the sauce consistency.
