Ingredients You’ll Need

This recipe relies on a handful of simple, fresh, and pantry-friendly ingredients that come together brilliantly. Each component plays a crucial role — from the juicy shrimp providing hearty texture, to the creamy sauce that wraps everything in rich flavor, and the crispy topping that adds an irresistible crunch.

• Shrimp (2 pounds): Choose large, peeled, and deveined shrimp for tender bites that soak up the sauce beautifully.
• Olive oil (2 tablespoons): Essential for giving the shrimp a quick sear that locks in moisture and flavor.
• Salt and pepper: Simple seasoning that enhances every element without overpowering the natural seafood taste.
• Butter (4 tablespoons): Provides a silky base for sautéing onions and garlic, adding richness to your cream sauce.
• Onion (1/2 cup finely chopped): Adds gentle sweetness and depth to the aromatics.
• Garlic (4 cloves minced): The star flavor that pairs perfectly with shrimp, providing that mouth-watering punch.
• Fresh basil (2 tablespoons chopped): Offers a bright herbal note. Dried basil works in a pinch.
• Ground nutmeg (1/8 teaspoon): A subtle warmth that rounds out the cream sauce beautifully.
• Heavy whipping cream (1 cup): The creamy, rich base for the sauce that ties all flavors together.
• Parmesan cheese (1 cup, divided): Nutty and salty, half falls into the sauce and half tops the dish for a golden crust.
• Monterey Jack cheese (1 cup shredded): Melts smoothly for extra gooeyness and flavor balance.
• Crushed pork rind crumbs (1/2 cup): The keto-friendly crunchy topping that adds amazing texture without carbs.

How to Make Keto Garlic Shrimp Au Gratin

Step 1: Preheat and Prepare Your Baking Dish

Start by preheating your oven to 375°F (190°C), allowing it to reach the perfect temperature for baking. Grease a large baking dish generously with butter or cooking spray. This step is vital since all the luscious ingredients will come together here, and nothing should stick or lose that beautiful crust you are about to create.

Step 2: Sear the Shrimp

Heat olive oil in a skillet over medium-high heat. Season your shrimp with salt and pepper, then gently sear them for 1 to 2 minutes per side. You want them to turn just pink and develop a slightly caramelized exterior — this gives the shrimp great flavor and the ideal texture before they hit the oven. Remove the shrimp from the skillet and set them aside, getting ready for the next delicious phase.

Step 3: Sauté the Aromatics

In the same skillet, melt the butter, letting it foam slightly. Add your finely chopped onions and cook until they soften, about 3 to 4 minutes. Then stir in the minced garlic, fresh basil, and a pinch of nutmeg, cooking for 30 seconds until the kitchen fills with aromatic goodness. These fragrant ingredients lay the flavor foundation of your creamy sauce.

Step 4: Create the Cream Sauce

Pour the heavy cream into the skillet, bringing it to a gentle simmer. Let it reduce and thicken a bit over 3 to 4 minutes, then stir in half of the parmesan cheese along with all the Monterey Jack cheese. Mix until the cheese has melted smoothly, resulting in a rich, velvety base that will complement the shrimp perfectly. Taste and adjust seasoning as needed.

Step 5: Place shrimp in the prepared baking dish and Assemble

Now comes the pivotal moment — Place shrimp in the prepared baking dish in an even layer. This ensures every forkful gets a balance of succulent shrimp and creamy goodness. Pour the warm cream sauce evenly on top of the shrimp, letting it cascade and nestle among the pieces.

Step 6: Add the Crispy Topping and Bake

Mix the remaining parmesan cheese with the crushed pork rind crumbs in a small bowl, creating a crunchy, cheesy topping that seals in moisture. Sprinkle this mixture evenly over your assembled shrimp and sauce. Bake uncovered for 25 minutes until the top turns beautifully golden and bubbly, signaling that your keto garlic shrimp au gratin is ready to dazzle.

How to Serve Keto Garlic Shrimp Au Gratin

Garnishes

A sprinkle of freshly chopped parsley or extra basil adds a bright burst of color and freshness that contrasts wonderfully with the creamy, cheesy dish. If you enjoy a little heat, a light dusting of red pepper flakes can bring warmth and a subtle kick that wakes up your taste buds.

Side Dishes

This dish shines as a standalone keto meal but pairs beautifully with crisp, green vegetables like roasted asparagus, sautéed spinach, or a fresh garden salad with a citrus vinaigrette. The lightness and acidity of these sides balance the richness of the shrimp au gratin perfectly.

Creative Ways to Present

For an impressive presentation, serve the shrimp au gratin in individual small ramekins. This personalized touch makes it look fancy but is easy to do and fun for guests or family. You can finish with lemon wedges on the side for an optional zesty squeeze that brightens every bite.

Make Ahead and Storage

Storing Leftovers

Let your dish cool completely before transferring leftovers to an airtight container. Stored properly in the refrigerator, it will stay delicious for 3 to 4 days. The creamy sauce will thicken as it cools, which only enhances the flavors over time.

Freezing

If you want to keep this gem longer, freeze it in a suitable container. Because of the cream, texture might shift slightly after thawing, but it will still be chewy, cheesy, and satisfying. Use within 1 to 2 months for best results, and thaw overnight in the fridge before reheating.

Reheating

Reheat leftovers gently in the oven at 325°F (160°C) to bring back the bubbly, golden top without drying out the shrimp. Alternatively, microwave on medium power in short bursts, stirring gently as needed. Adding a splash of cream or water can help loosen the sauce if it’s too thick.

FAQs

Can I use frozen shrimp for this recipe?

Absolutely! Just be sure to thaw the shrimp completely and pat them dry before searing. This helps prevent excess water from diluting your sauce and keeps the shrimp texture firm and delicious.

What if I don’t have pork rinds for the topping?

You can substitute with crushed pork cracklings, almond flour mixed with parmesan, or even finely chopped toasted nuts—each adds a nice crunch while keeping it keto-friendly.

Is this recipe suitable for a low-carb diet?

Yes, this Keto Garlic Shrimp Au Gratin is specifically designed to be low-carb by using heavy cream, cheeses, and pork rind crumbs instead of bread crumbs, making it perfect for keto and other low-carb lifestyles.

Can I make this dish vegetarian or use another protein?

While shrimp is the star here, you can experiment with chicken pieces or firm tofu cubes as alternatives. For vegetarians, omit the shrimp and add mushrooms or cauliflower florets to soak up the sauce while still capturing the essence of the dish.

How can I tell when the dish is done baking?

The top should be a rich golden brown with bubbles forming around the edges. The sauce will be thick and creamy, and the shrimp thoroughly cooked (opaque and pink). Around 25 minutes at 375°F usually does the trick.
