  • 2 tablespoons olive oil
  • to taste Salt and pepper
Creamy Sauce
  • 4 tablespoons butter
  • 1/2 cup finely chopped onion
  • 4 cloves garlic (minced)
  • 2 tablespoons fresh basil (chopped, or 1 tablespoon dried)
  • 1/8 teaspoon ground nutmeg

  • 1 cup shredded Monterey Jack cheese

Method
 

Preparation
  1. Preheat oven to 375°F (190°C). Grease a large baking dish with butter or cooking spray.
  2. 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.
  3. In the same skillet, melt butter. Add chopped onion and sauté until soft (3–4 minutes). Toss in garlic, basil, and nutmeg. Cook for 30 seconds until fragrant.
  4. Pour in the heavy cream and simmer for 3–4 minutes until slightly thickened. Stir in 1/2 cup parmesan and all the Monterey Jack cheese. Mix until smooth. Season to taste.
  5. Place shrimp in the prepared baking dish. Pour the cream sauce evenly over the shrimp.
  6. In a small bowl, mix the remaining 1/2 cup parmesan with crushed pork rinds. Sprinkle mixture over the dish.
  7. Bake for 25 minutes until the top is golden and sauce is bubbling.

Notes

If you have leftovers, store them in an airtight container in the fridge for about 3 days. Reheat in the oven or microwave, adding a splash of cream or stock to maintain creaminess.
