Tips & Variations
- For added flavor, toss the shrimp in a little smoked paprika before searing.

- Use smoked gouda or cheddar cheese for a different cheesy twist.
- If you prefer, replace pork rind crumbs with crushed almonds or seasoned keto breadcrumbs.

Ingredients
Shrimp and Seasonings
- 2 pounds large shrimp, peeled, deveined, tails removed
- 2 tablespoons olive oil
- Salt and pepper to taste
Sauce
- 4 tablespoons butter
- 1/2 cup finely chopped onion
- 4 cloves garlic, minced
- 2 tablespoons fresh basil, chopped (or 1 tablespoon dried basil)
- 1/8 teaspoon ground nutmeg
- 1 cup heavy whipping cream
- 1/2 cup grated parmesan cheese (divided)
- 1 cup shredded Monterey Jack cheese
Topping
- 1/2 cup crushed pork rind crumbs
- Remaining 1/2 cup grated parmesan cheese
Instructions
- Preheat Oven: Preheat your oven to 375°F (190°C). Grease a large baking dish with butter or cooking spray to prevent sticking and ensure easy cleanup.
- Sear Shrimp: Heat olive oil in a large skillet over medium-high heat. Season the shrimp with salt and pepper, then sear each side for 1 to 2 minutes until just pink and opaque. Remove the shrimp from the skillet and set aside to prevent overcooking later.
- Sauté Aromatics: In the same skillet, melt the butter over medium heat. Add the finely chopped onion and sauté for 3 to 4 minutes until soft and translucent. Stir in the minced garlic, chopped basil, and ground nutmeg, cooking for an additional 30 seconds until fragrant.
- Make Cream Sauce: Pour the heavy whipping cream into the skillet and allow it to simmer gently for 3 to 4 minutes until it thickens slightly. Stir in half of the parmesan cheese (1/2 cup) along with the shredded Monterey Jack cheese. Mix until the sauce is smooth and creamy. Season with salt and pepper to taste.
- Assemble Dish: Arrange the seared shrimp evenly in the prepared baking dish. Pour the rich cream sauce over the shrimp, ensuring all pieces are covered with the cheesy mixture.
- Add Topping: In a small bowl, combine the remaining 1/2 cup grated parmesan cheese with the crushed pork rind crumbs. Sprinkle this mixture evenly over the top of the shrimp and sauce to create a crispy, flavorful crust.
- Bake: Place the baking dish in the preheated oven and bake for 25 minutes, or until the topping is golden brown and the sauce is bubbly. Remove from oven and allow to cool slightly before serving.
Notes
- For best results, use fresh shrimp and be careful not to overcook during searing to maintain a tender texture.
- Crushed pork rinds provide a low-carb breadcrumb substitute perfect for keto diets; you can also add herbs such as parsley to the topping for extra flavor.
- If you prefer a spicier version, add a pinch of red pepper flakes when sautéing the garlic.
- Leftovers can be stored covered in the refrigerator for up to 2 days and reheated gently in the oven.
- This dish pairs well with steamed or roasted low-carb vegetables for a complete keto-friendly meal.
