Ingredients
Instructions
- Preheat oven to 450°F with rack in top position. Bring a large pot of salted water to a boil. Cut broccoli into 1-inch florets. Zest and quarter the lemon. 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.
- Add spaghetti to boiling water and cook until al dente, 9-11 minutes. Reserve ½ cup pasta water, then drain.
- Place butter in a small microwave-safe bowl and microwave until softened, about 10 seconds. Stir in lemon zest, half the Parmesan, a pinch of garlic and a pinch of chili flakes. Mash with a fork; season with salt and pepper.
- Rinse shrimp and pat dry. Toss with olive oil, remaining garlic, salt and pepper. Heat a large pan over medium-high heat. Cook shrimp until opaque, 2-4 minutes.
- Add drained spaghetti, roasted broccoli, stock concentrate, garlic butter and ¼ cup reserved pasta water to the pan. Toss to coat. Squeeze in lemon juice to taste; season with salt and pepper. Serve topped with remaining Parmesan and chili flakes, with lemon wedges on the side.
Recipe Tips
For extra crispy broccoli, don’t overcrowd the baking sheet.
Reserve more pasta water than you think you need; it helps create a silky sauce.
If you prefer less heat, reduce or omit the chili flakes.
