Equipment

  • oven
  • large skillet
  • Baking dish

Ingredients
  

Seafood

  • 2 pounds large shrimp peeled, deveined, tails removed

Cooking Essentials

  • 2 tablespoons olive oil
  • 1 pinch salt to taste
  • 1 pinch pepper to taste
  • 4 tablespoons butter

Aromatics

  • ½ cup finely chopped onion
  • 4 cloves garlic minced
  • 2 tablespoons fresh basil chopped (or 1 tablespoon dried)
  • ⅛ teaspoon ground nutmeg

Cream Base

  • 1 cup heavy whipping cream
  • 1 cup grated parmesan cheese divided
  • 1 cup shredded monterey jack cheese
  • ½ cup crushed pork rind crumbs

Instructions
 

Cooking Steps

  • Preheat oven to 375°F (190°C). Grease a large baking dish with butter or cooking spray.
  • Heat olive oil in a large skillet over medium-high heat. Season shrimp with salt and pepper, then sear for 1–2 minutes per side until just pink. Remove from skillet and set aside.
  • In the same skillet, melt butter. Add chopped onion and sauté until soft (3–4 minutes). Add garlic, basil, and nutmeg. Cook for 30 seconds until fragrant.
  • Pour in heavy cream and simmer 3–4 minutes until slightly thickened. Stir in ½ cup parmesan and all the Monterey jack cheese. Mix until smooth. Season to taste.
  • Place shrimp in the prepared baking dish. Pour the cream sauce evenly over the shrimp.
  • In a small bowl, mix the remaining ½ cup parmesan with crushed pork rinds. Sprinkle mixture over the dish.
  • Bake for 25 minutes until top is golden and sauce is bubbling.

Notes

Use fresh garlic and fresh basil for best flavor. Avoid overcooking shrimp; they continue cooking in the oven. Store leftovers in the fridge for up to 3 days. Reheat gently on stovetop or in microwave. Sauce may separate when reheated—just stir gently to restore creaminess.
