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, then drain.
- While pasta cooks, place 3 tablespoons butter in a small microwave-safe bowl. Microwave until just softened, 10 seconds. Add lemon zest, half the Parmesan, 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. 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 crispy broccoli, don’t overcrowd the baking sheet.
Reserve more pasta water than needed to adjust sauce consistency.
Cook shrimp just until opaque to avoid toughness.
