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.
Step 2: Sear Shrimp
Heat olive oil in a large skillet over medium-high heat. Season the shrimp with salt and pepper. Sear them for 1–2 minutes per side until they are just pink. Remove from skillet and set aside.
Step 3: Sauté Aromatics
In the same skillet, melt butter over medium heat. Add finely chopped onion and sauté until soft (about 3–4 minutes). Then add minced garlic, chopped basil, and ground nutmeg. Cook for an additional 30 seconds until fragrant.
Step 4: Make Cream Sauce
Pour in heavy cream into the skillet and let it simmer for about 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. Season to taste with salt and pepper.
Step 5: Assemble Dish
Place the seared shrimp evenly in the prepared baking dish. Pour the creamy sauce mixture over the shrimp, ensuring even coverage.
Step 6: Add Topping
In a small bowl, combine the remaining 1/2 cup of parmesan cheese with crushed beef rinds. Sprinkle this mixture evenly over the top of the dish to create a crispy topping.
Step 7: Bake
Bake in preheated oven for about 25 minutes or until the top is golden brown and the sauce is bubbling around the edges.
