- 2 tablespoons fresh basil (or 1 tablespoon dried): Introduces a bright, herbal lift and beautiful color contrast.
- 1/8 teaspoon ground nutmeg: A subtle warming note that elevates the creamy sauce’s complexity.

How to Make Keto Garlic Shrimp Au Gratin Recipe
Step 1: Preheat and Prepare
Begin by heating your oven to 375°F (190°C) and greasing a large baking dish with butter or a spritz of cooking spray. This ensures your shrimp au gratin won’t stick and helps the topping get perfectly golden.
Step 2: Sear the Shrimp
Heat olive oil in a large skillet over medium-high heat. Season your shrimp with salt and pepper, then sear each side for just 1 to 2 minutes until they turn a lovely pink. The goal is to get a light caramelization on the outside while keeping them tender inside. Remove from the skillet and set aside for the next step.
Step 3: Sauté the Aromatics
Use the same skillet to melt the butter, letting it soak up any shrimp goodness left behind. Toss in the finely chopped onion and sauté for about 3 to 4 minutes until soft and translucent. Add the minced garlic, chopped basil, and a pinch of ground nutmeg, cooking everything for about 30 seconds until the aroma fills your kitchen.
Step 4: Create the Cream Sauce
Pour in the heavy whipping cream and bring to a gentle simmer. Let it thicken slightly over 3 to 4 minutes, then stir in half of the parmesan cheese and all of the Monterey Jack cheese. Combine until smooth and luscious, then season to taste with salt and pepper. This is the sauce that transforms simple shrimp into something extraordinary.
Step 5: Assemble for Baking
Place the seared shrimp evenly in your prepared baking dish. Pour the rich cream sauce over the shrimp, making sure every piece gets a generous coating.
Step 6: Add the Crunchy Topping
In a small bowl, mix the remaining parmesan cheese with the crushed pork rind crumbs. Sprinkle this mixture evenly over the dish — this topping is where all the magic of golden, crispy texture happens.
Step 7: Bake Until Bubbling and Golden
Bake in your preheated oven for about 25 minutes, or until the topping is golden brown and the sauce is bubbling around the edges. The visual and aromatic cues will signal that it’s ready to enjoy.
How to Serve Keto Garlic Shrimp Au Gratin Recipe

Garnishes
A sprinkle of freshly chopped parsley or extra basil on top not only adds a pop of color but also a fresh herbal brightness that perfectly complements the rich, garlicky flavors.
Side Dishes
This shrimp au gratin stands well on its own but pairs beautifully with simple keto-friendly sides like steamed broccoli, sautéed spinach, or a crisp green salad with a zesty vinaigrette. These light sides balance the richness of the dish wonderfully.
Creative Ways to Present
To elevate the plating, try serving individual portions in small ramekins or cast iron skillets for a rustic, restaurant-style feel. Add a lemon wedge on the side for guests to squeeze over, brightening the creamy garlicky flavors even more.
Make Ahead and Storage
Storing Leftovers
After your Keto Garlic Shrimp Au Gratin Recipe cools to room temperature, cover it tightly with foil or transfer to an airtight container. It will keep in the refrigerator for up to 3 days, perfect for enjoying a quick, delicious meal later.
Freezing
While freezing this dish is possible, the texture of the cream sauce may change slightly after thawing. If you choose to freeze, do so in an airtight container and consume within 1 month. Thaw overnight in the fridge before reheating.
Reheating
Reheat leftovers gently in a 350°F oven for about 15 minutes or until warmed through. Cover loosely with foil to prevent the topping from burning while preserving that inviting golden crust on top.
FAQs
Can I use frozen shrimp for this recipe?
Yes, frozen shrimp works fine as long as it’s completely thawed and patted dry before cooking. This ensures even searing and the best texture in your au gratin.
What can I substitute for pork rind crumbs?
If you don’t have pork rinds on hand, crushed almonds or ground flaxseed mixed with parmesan can also create a crunchy, low-carb topping.
Is this recipe dairy-free?
This dish is not dairy-free since it uses heavy cream, butter, and cheese, which are key to its creamy, rich texture.
Can I prepare this Keto Garlic Shrimp Au Gratin Recipe ahead of time?
Absolutely! You can prepare everything up through assembling the baking dish, then cover and refrigerate it until ready to bake. Just add a few extra minutes to baking time if it comes straight from the fridge.
How do I make it spicier?
To add some heat, toss a pinch of red pepper flakes into the sauce during cooking or sprinkle some cayenne powder over the shrimp before searing for a spicy kick.
