  • Total Time: 30 minutes
  • Yield: 4 servings 1x

Ingredients

Scale

1.5 lbs large shrimp, peeled and deveined

4 tablespoons unsalted butter

6 cloves garlic, minced

1/2 cup chicken or vegetable broth

1 cup heavy whipping cream

4 oz cream cheese, softened and cubed

1/2 cup grated Parmesan cheese, plus more for topping

1/2 teaspoon black pepper

1/4 teaspoon salt (or to taste)

1 teaspoon fresh parsley, chopped

1/2 cup shredded mozzarella or Gruyère cheese

1/2 cup crushed pork rinds or 1/4 cup almond flour (optional topping)

Instructions

1. Preheat oven to 375°F (190°C) and lightly grease a baking dish or individual ramekins.

2. Melt butter in a skillet over medium heat and sauté garlic for 1-2 minutes until fragrant.

3. Pour in broth to deglaze, simmer briefly, then reduce heat.

4. Whisk in heavy cream and cream cheese until fully melted and smooth.

5. Stir in Parmesan, salt, pepper, and parsley until sauce thickens slightly.

6. Add shrimp and stir gently, cooking just 1-2 minutes until they start to turn pink.

7. Transfer mixture to baking dish and spread evenly.

8. Top with mozzarella or Gruyère, extra Parmesan, and optional pork rinds or almond flour.

9. Bake 15-20 minutes until bubbly and golden brown.

10. Let rest 5 minutes, then garnish with fresh parsley and serve.

Notes

Use raw shrimp for the best texture; pre-cooked shrimp tend to become rubbery. For a perfectly smooth sauce, melt dairy on low heat and use freshly grated cheeses. Broil the top for 1-2 minutes for extra crispiness, watching closely. Serve with roasted asparagus, zoodles, or cauliflower mash to complete the meal.
