How to Make Keto Garlic Shrimp Au Gratin
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). Grease a large baking dish with butter or cooking spray to prevent sticking.

In a large skillet over medium-high heat, heat olive oil. Season the shrimp with salt and pepper. Sear them for 1–2 minutes on each side until just pink. Remove from skillet and set aside.
Step 3: Sauté Aromatics
In the same skillet, melt the butter. Add finely chopped onion and sauté until soft (about 3–4 minutes). Then add minced garlic, chopped basil, and nutmeg. Cook for about 30 seconds until fragrant.
Step 4: Make Cream Sauce
Pour in the heavy cream and simmer for 3–4 minutes until slightly thickened. Stir in 1/2 cup of parmesan cheese along with all of the Monterey jack cheese. Mix until smooth and season to taste.
Step 5: Assemble Dish
Place the seared shrimp into the prepared baking dish. Pour the creamy sauce evenly over the shrimp.
Step 6: Add Topping
In a small bowl, combine the remaining 1/2 cup of parmesan cheese with crushed beef rinds. Sprinkle this mixture over the top of your shrimp dish.
Step 7: Bake
Bake in preheated oven for about 25 minutes or until the top is golden brown and bubbling around edges. Enjoy your delicious Keto Garlic Shrimp Au Gratin!

How to Perfect Keto Garlic Shrimp Au Gratin
To ensure your Keto Garlic Shrimp Au Gratin turns out perfectly every time, follow these helpful tips.
- Use Fresh Shrimp: For the best flavor and texture, opt for fresh or high-quality frozen shrimp.
- Don’t Overcook the Shrimp: Sear shrimp just until they turn pink; they will cook further in the oven.
- Adjust Spice Levels: Feel free to add more garlic or herbs based on your taste preferences to enhance flavor.
- Let it Rest: Allow the dish to sit for a few minutes after baking; this helps thicken the sauce and makes serving easier.
- Experiment with Cheeses: Mix different cheeses like gouda or cheddar for a unique flavor profile.
- Store Leftovers Properly: Keep leftovers in an airtight container in the fridge for up to 3 days.

- Garlic Butter Mushrooms: Sautéed mushrooms in garlic butter add earthiness and depth to your plate.
- Coleslaw (Keto Style): A crunchy cabbage slaw dressed in mayonnaise is refreshing next to creamy dishes.
- Baked Brussels Sprouts: Roasted Brussels sprouts seasoned with herbs provide a crispy texture that contrasts nicely with the au gratin.
Common Mistakes to Avoid
When making Keto Garlic Shrimp Au Gratin, being aware of common pitfalls can enhance your cooking experience.
- Bold seasoning: Many forget to season shrimp adequately. Season with salt and pepper before searing for maximum flavor.
- Bold overcooking shrimp: Searing shrimp too long can lead to rubbery textures. Cook just until pink and opaque, about 1–2 minutes per side.
- Bold rushing the cream sauce: Thickening the cream sauce too quickly can cause it to separate. Simmer gently, allowing it time to thicken naturally.
- Bold ignoring cheese quality: Using low-quality cheese can affect the dish’s richness. Opt for freshly grated parmesan and high-quality Monterey jack for better melting and flavor.
- Bold skipping the baking step: Some may skip the baking process thinking it’s unnecessary. Baking melds the flavors and creates a deliciously crispy topping.
