-
Preheat Oven: Begin by setting your oven to 375°F (190°C). While it’s heating, grease a large baking dish to prevent sticking.

Sear Shrimp: Heat a drizzle of olive oil in a skillet over medium-high heat. Season your shrimp with salt and pepper, cooking them for about 1-2 minutes on each side until they turn pink. Remove and set them aside.

Make Cream Sauce: Pour in the heavy whipping cream, and let it simmer until it thickens slightly, which should take about 5 minutes. Mix in the grated Parmesan and shredded Monterey Jack cheese, stirring until it’s smooth and creamy. Adjust seasoning to taste.
-
Assemble Dish: Place your seared shrimp in the greased baking dish. Pour the luscious cream sauce over the shrimp, making sure they’re all nicely coated.

Keto Garlic Shrimp Au Gratin Recipe FAQs
What type of shrimp should I use for this recipe?
I recommend using large shrimp that are fresh, peeled, and deveined for optimal flavor and quick cooking. Look for shrimp that are firm and slightly translucent; avoid any with dark spots or a strong fishy smell. If fresh isn’t available, frozen shrimp can be a good alternative—just ensure they are fully thawed before cooking.
How should I store leftover Keto Garlic Shrimp Au Gratin?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Allow it to cool completely before sealing to maintain freshness and prevent condensation. When you’re ready to enjoy it again, simply reheat it gently in the oven to restore its creamy texture.
Can I freeze Keto Garlic Shrimp Au Gratin?
Absolutely! For long-term storage, you can freeze portions of this dish in airtight containers for up to 2 months. Ensure you label them with the date for your convenience. To reheat, thaw in the refrigerator overnight before warming it gently in the oven at 350°F (175°C) until heated throughout.
What should I do if my cream sauce separates while reheating?
Don’t worry! If you find that the sauce separates upon reheating, just whisk it gently to bring it back together. This will help restore its luscious consistency. You can also add a splash of cream or milk if needed to help smooth it out.
Is this dish safe for pets or people with allergies?
While the Keto Garlic Shrimp Au Gratin is delicious for humans, it’s not suitable for pets due to the garlic content, which can be harmful to them. Additionally, be cautious of allergies!

Yes! To make the Keto Garlic Shrimp Au Gratin dairy-free, you can replace the heavy cream with a coconut cream alternative and use dairy-free cheese options. Be aware that this may alter the overall taste and texture, but it’s definitely worth trying if you’re looking for a dairy-free option.
