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 the oven heats up, take a moment to generously grease a large baking dish with cooking spray or butter to prevent sticking. This preparation ensures that your Keto Garlic Shrimp Au Gratin will bake evenly and won’t cling to the dish.
Step 2: Sear Shrimp
In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Season the 2 pounds of peeled and deveined shrimp with salt and pepper, then add them to the hot skillet. Sear for about 1-2 minutes on each side until the shrimp turn a vibrant pink and are just cooked through. Remove them from the skillet and set aside to keep them tender.
Step 3: Sauté Aromatics
With the skillet still on the heat, add 4 tablespoons of butter. Once melted, toss in ½ cup of finely chopped onion and sauté for about 3-4 minutes until they become translucent. Then, add in 4 cloves of minced garlic, 2 tablespoons of chopped fresh basil, and ⅛ teaspoon of ground nutmeg, stirring for 30 seconds until the mixture is aromatic and fragrant.
Step 4: Make Cream Sauce
Pour in 1 cup of heavy whipping cream into the sautéed mixture, and bring it to a gentle simmer. Cook for about 3-4 minutes, allowing the sauce to thicken slightly. Next, stir in ½ cup of grated Parmesan cheese and all of the 1 cup shredded Monterey Jack cheese until the sauce is smooth and creamy. Taste and adjust seasoning with more salt or pepper if necessary for your Keto Garlic Shrimp Au Gratin.
Step 5: Assemble Dish
Reduce the heat to low, then place the previously seared shrimp into the greased baking dish. Pour the luscious cream sauce evenly over the shrimp, making sure every piece is covered. This creates a beautiful layer of cheesy goodness that will meld perfectly during baking.
Step 6: Add Topping
In a small bowl, combine the remaining ½ cup of grated Parmesan cheese with ½ cup of crushed pork rind crumbs. This mixture will become the crunchy topping for your dish. Evenly sprinkle it over the shrimp and cream sauce in the baking dish, providing that crispy contrast that everyone loves.
Step 7: Bake
Place the assembled dish into the preheated oven and bake for around 25 minutes. Watch as the top turns golden brown and the sauce begins to bubble enticingly. The delicious aroma will fill your kitchen, signaling that your Keto Garlic Shrimp Au Gratin is almost ready to be savored.

Make Ahead Options
These Keto Garlic Shrimp Au Gratin are a fantastic choice for meal prep enthusiasts! You can sear the shrimp and prepare the creamy sauce up to 24 hours in advance. Simply allow the shrimp to cool completely, then cover and refrigerate them along with the sauce in an airtight container. When you’re ready to serve, pour the sauce over the shrimp, sprinkle the topping on, and bake as directed. This approach not only saves you precious time on busy weeknights but also keeps the dish just as delicious and comforting as when freshly made. Perfect for those who want a quick and satisfying dinner without the stress!
How to Store and Freeze Keto Garlic Shrimp Au Gratin
Fridge: Store leftovers in an airtight container for up to 3 days. This will keep your Keto Garlic Shrimp Au Gratin fresh and delicious for later enjoyment.
Freezer: For longer storage, freeze in a tightly sealed container for up to 3 months. Avoid freezing the dish with the crunchy topping, as it may lose its texture when reheated.

Keto Garlic Shrimp Au Gratin Recipe FAQs
How do I select the best shrimp for this recipe?
Absolutely! Opt for large shrimp that are fresh, plump, and opaque in color. Avoid any shrimp with dark spots or strong fishy odors, as these are indicators of poor quality. Always choose peeled and deveined shrimp for a convenient cooking experience.
How should I store leftovers of Keto Garlic Shrimp Au Gratin?
For sure! Store any leftovers in an airtight container in the refrigerator for up to 3 days. This keeps your dish fresh and ready to enjoy later. Just remember to reheat gently in the oven to restore its creamy texture.
Can I freeze Keto Garlic Shrimp Au Gratin?
Yes, you can! To freeze, transfer the dish to a tightly sealed container and store it for up to 3 months. However, I recommend freezing it without the crunchy topping, as it may lose its delightful crunch when reheated.
What should I do if the cream sauce is too thin?
Very good question! If your cream sauce is thinner than you’d like, simmer it a bit longer after adding the cheese, allowing it to thicken. Stir continuously to prevent sticking; about 2-3 more minutes should do the trick. Patience is key for a creamy, luscious sauce!
Are there any dietary considerations I should be aware of?
Absolutely! If you’re preparing this dish for someone with shellfish allergies, you’ll want to steer clear of shrimp altogether. For those on a keto diet, rest assured that this recipe is tailored to be low-carb. If you’re serving pets, remember that cheese and garlic should be avoided, so keep it human-only!
