Ingredients
  

  • 1 lb 450 g large shrimp, peeled & deveined
  • 2 tbsp butter
  • 3 cloves garlic minced
  • 1 cup heavy cream
  • ½ cup chicken or seafood broth
  • 1 cup shredded mozzarella
  • ½ cup grated Parmesan
  • 1 tsp smoked paprika
  • Salt & black pepper to taste
  • 1 tbsp lemon juice
  • 2 tbsp chopped parsley for garnish
  • Optional: ¼ tsp crushed red pepper flakes

Instructions
 

  • Preheat oven to 400°F (200°C).
  • Sear the shrimp: Melt 1 tbsp butter in a skillet. Season shrimp with paprika, salt, and pepper. Sear 1–2 minutes per side until lightly browned (they’ll finish cooking in the oven). Remove and set aside.
  • Make the creamy sauce: Add remaining butter and garlic to the skillet. Sauté 30 seconds. Pour in heavy cream, broth, and lemon juice. Simmer 2–3 minutes.
  • Add the cheese: Stir in mozzarella and Parmesan until melted and smooth.
  • Assemble: Pour sauce into a baking dish. Nestle seared shrimp on top.
  • Bake: 10–12 minutes, or until bubbling and lightly golden.
  • Garnish & serve: Sprinkle chopped parsley over the top. Serve warm.

Notes

Tips & Variations

  • Add veggies: Spinach, mushrooms, or roasted cherry tomatoes pair beautifully.
  • Use different cheese: Gruyère, white cheddar, or fontina add depth of flavor.
  • Extra flavor: A splash of white wine in the sauce enhances richness.
  • Spicy version: Increase crushed red pepper or add Cajun seasoning.
  • Avoid rubbery shrimp: Add undercooked shrimp to sauce; residual oven heat will finish cooking.
