Step‑by‑Step Instructions for Keto Garlic Shrimp Au Gratin

Step 1: Preheat Oven
Begin by preheating your oven to 375°F (190°C). While it heats, grab a baking dish and lightly grease it with cooking spray or a touch of olive oil, ensuring a non-stick surface for your creamy Keto Garlic Shrimp Au Gratin.

Step 2: Sear Shrimp
In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Once hot, add the peeled and deveined large shrimp. Season with salt and pepper, and cook for about 2-3 minutes until the shrimp turn pink and opaque. Remove the shrimp from the skillet and set aside temporarily as you prepare the sauce.

Step 3: Sauté Aromatics
Using the same skillet, melt 2 tablespoons of butter over medium heat. Add the chopped onion and sauté for 3-4 minutes until they become soft and translucent. Then, stir in the minced garlic, fresh basil, and a pinch of nutmeg, cooking for an additional 30 seconds until the mixture becomes fragrant and inviting.

Step 4: Make Cream Sauce
Pour in 1 cup of heavy whipping cream into the skillet, stirring well. Let this simmer for 3-4 minutes, allowing it to thicken slightly. Next, mix in half of the grated Parmesan cheese and all of the shredded Monterey Jack cheese, stirring until the cheese is melted and the sauce is smooth. Adjust flavor with salt and pepper as needed.

Step 5: Assemble Dish
Now, transfer the cooked shrimp to your greased baking dish, spreading them evenly. Carefully pour the rich cream sauce over the shrimp, ensuring every piece is coated. For the topping, sprinkle the remaining Parmesan cheese and crushed pork rind crumbs evenly across the surface, adding texture and crunch to your Keto Garlic Shrimp Au Gratin.

Step 6: Bake
Place the baking dish in the preheated oven and bake for 25 minutes. Watch closely as the top turns golden and the sauce begins to bubble delightfully. Once it reaches that perfect bubbling stage, remove the dish from the oven and let it rest for a few minutes before serving. Enjoy the creamy, luxurious flavors!
