Step‑by‑Step Instructions for Keto Garlic Shrimp Au Gratin
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While the oven warms up, grab a large baking dish and lightly grease it with a bit of olive oil or butter to prevent your cheesy creation from sticking once baked. This step ensures that your Keto Garlic Shrimp Au Gratin bakes evenly and achieves a bubbly finish.
Step 2: Sear the Shrimp
In a spacious skillet, heat a drizzle of olive oil over medium heat. Once shimmering, season your large, peeled shrimp with salt and pepper before adding them to the skillet. Sear the shrimp for about 1-2 minutes on each side, until they turn pink and opaque. Remove the shrimp from the skillet and set them aside, allowing them to retain their juicy texture.
Step 3: Sauté the Aromatics
Using the same skillet, reduce the heat to medium-low and add a generous tablespoon of butter. As the butter melts, add finely chopped onions and sauté them until they soften and become translucent, about 3-4 minutes. Next, stir in minced garlic, fresh basil, and a pinch of nutmeg, cooking the mixture for an additional minute until fragrant, creating a delightful aroma in your kitchen.
Step 4: Create the Cream Sauce
Pour in heavy whipping cream into the skillet with the sautéed aromatics. Let it simmer gently for about 5 minutes, stirring occasionally, until slightly thickened. Next, gradually sprinkle in both Parmesan and Monterey Jack cheeses, stirring continuously until the sauce is smooth and creamy. Taste and adjust the seasoning with salt and pepper if needed, ensuring your Keto Garlic Shrimp Au Gratin is bursting with flavor.
Step 5: Assemble the Dish
Spread the seared shrimp evenly in your prepared baking dish. Carefully pour the rich cream sauce over the shrimp, making sure they are generously coated with the velvety deliciousness. This layering of shrimp and sauce creates the perfect foundation for your dish, promising a beautiful combination of textures and flavors.
Step 6: Prepare the Crunchy Topping
In a small bowl, mix the remaining Parmesan cheese with crushed pork rind crumbs to create a crunchy topping. This low-carb alternative to breadcrumbs adds a delightful crunch without ruining your keto goals. Sprinkle the mixture evenly over the creamy shrimp in the baking dish, giving it a beautiful golden crown once baked.
Step 7: Bake to Perfection
Place your assembled Keto Garlic Shrimp Au Gratin in the preheated oven and bake for 25 minutes. Keep an eye on it; the topping should turn golden and crispy, while the sauce bubbles enticingly. Once done, remove it from the oven and let it rest for a few minutes, allowing the flavors to settle before serving.

Keto Garlic Shrimp Au Gratin Recipe FAQs
How do I choose the right shrimp for this recipe?
Absolutely! When selecting shrimp, look for large, peeled, and deveined varieties for the best flavor and texture. Fresh shrimp should have a mild sea-like smell and a firm texture. Avoid shrimp with dark spots or an overly fishy odor, as these signs may indicate that they are no longer fresh.

Very! If you find the cream sauce is thicker than you’d like, simply add a splash of chicken broth or a bit more heavy cream while it simmers. Stir continuously until you reach your desired consistency. This way, you’ll maintain that luscious pour-over texture that makes your dish so delightful.
Is this Keto Garlic Shrimp Au Gratin suitable for those with dairy allergies?
If you’re looking for a dairy-free option, I recommend trying plant-based cheese alternatives and coconut cream in place of heavy cream.
