Ingredients You’ll Need

This keto shrimp au gratin comes together with a handful of simple ingredients that you probably already have in your kitchen. Each one plays a role in building that creamy, cheesy, bubbling goodness:

• Shrimp (1 lb, peeled and deveined) – Fresh or thawed shrimp work best. Medium to large size keeps them juicy after baking.
• Butter (2 tbsp) – For sautéing garlic and onion, adding richness right from the start.
• Garlic (3–4 cloves, minced) – The star flavor that infuses the sauce with warmth.
• Onion (½ small, finely chopped) – Adds a subtle sweetness and depth to the creamy base.
• Heavy cream (1 cup) – Keeps the sauce velvety and keto-friendly, with fewer carbs than milk.
• Grated Parmesan (½ cup) – Sharp, salty, and perfect for flavor and melting into the sauce.
• Shredded Monterey Jack (1 cup) – Creamy, melty, and balances the Parmesan with a smooth texture.
• Fresh basil (1 tbsp, chopped) – Adds freshness and color. You can sub with parsley if needed.
• Nutmeg (a pinch) – Optional, but adds warmth and depth to creamy sauces.
• Pork rinds (½ cup, crushed) – A brilliant low-carb swap for breadcrumbs that gives a crunchy topping.
• Salt & black pepper – To taste, rounding out the flavors.

Step-by-Step Instructions

Follow these easy steps to create a bubbling, cheesy shrimp au gratin that’s keto-friendly and irresistibly delicious:

1. Prep the shrimp. Pat the shrimp dry with paper towels and season lightly with salt and pepper. This keeps them from steaming and ensures they hold their flavor when baked.
2. Sauté the aromatics. In a large oven-safe skillet, melt the butter over medium heat. Add the onion and cook for 3–4 minutes until softened and fragrant. Stir in the garlic and cook just 30 seconds more—enough to release that amazing aroma without burning it.
3. Make the creamy base. Pour in the heavy cream and bring to a gentle simmer. Stir in the Parmesan, Monterey Jack, basil, and a tiny pinch of nutmeg. The sauce should turn silky and smooth as the cheese melts in. Taste and adjust with salt and pepper.
4. Add the shrimp. Nestle the shrimp into the creamy sauce in a single layer. They don’t need long in the oven, so this step is all about giving them a head start in the sauce.
5. Top and bake. Sprinkle the crushed pork rinds evenly over the top for that golden au gratin crunch. Slide the skillet into a preheated oven at 375°F (190°C). Bake for 18–20 minutes, until the shrimp are pink and cooked through, and the top is bubbling and golden.
6. Serve hot. Bring the skillet right to the table for a rustic, family-style presentation. Garnish with extra basil or parsley if you like, and serve immediately while the cheese is melty and irresistible.

Tips & Variations

This keto shrimp au gratin is wonderfully flexible, so you can easily make it your own. Here are some fun ways to switch it up or adapt it to your preferences:

Flavor Boosts

• Add spice: Mix in a pinch of red pepper flakes or cayenne for a little heat.

• Herb upgrade: Fresh thyme or oregano can stand in for basil for a deeper, earthy taste.

Extra Add-Ins

Keto-Friendly Hacks
