Instructions

  1. Preheat your oven to 425°F (220°C). Bring a large pot of salted water to a boil.
  2. Cut the broccoli into small florets. Toss with a drizzle of olive oil, salt and pepper. Spread on a baking sheet and roast for 15-18 minutes until tender and lightly charred.
  3. While the broccoli roasts, cook the spaghetti according to package directions until al dente. Reserve 1 cup of pasta water before draining.
  4. Zest and juice the lemon. Mince the garlic cloves. Pat the shrimp dry and season with salt and pepper.
  5. In a large skillet, melt 2 tablespoons of butter with 1 tablespoon of olive oil over medium heat. Add the shrimp and cook 2-3 minutes per side until pink and opaque. Remove shrimp and set aside.
  6. In the same skillet, add the remaining 1 tablespoon butter and minced garlic. Cook for 30 seconds until fragrant. Stir in the seafood stock concentrate, lemon zest, lemon juice and chili flakes. Cook for 1 minute.
  7. Add the cooked spaghetti and 1/4 cup of reserved pasta water to the skillet. Toss to coat. If the sauce seems dry, add more pasta water a little at a time.
  8. Return the shrimp to the skillet and add the roasted broccoli. Toss everything together. Remove from heat and stir in the Parmesan cheese. Serve immediately.

Recipe Tips

For extra crisp broccoli, don’t overcrowd the baking sheet.

Reserve more pasta water than you think you’ll need-it’s the key to a silky sauce.

Cook shrimp just until pink; overcooking makes them rubbery.
