👩‍🍳 Step-by-Step Instructions

Step 1: Preheat and Prep

• Set your oven to 375°F (190°C).
• Grease a medium-sized baking dish with a bit of olive oil or butter to keep things from sticking.

Step 2: Sear the Shrimp

• Heat 2 tbsp olive oil in a skillet over medium-high heat.
• Pat the shrimp dry with a paper towel (dry shrimp sear better!).
• Season the shrimp with salt and pepper.
• Sear them in the hot skillet until they turn pink and are just cooked through—about 1–2 minutes per side.
• Remove from heat and set aside.

Step 3: Make the Garlic Cream Sauce

• In a saucepan, melt 3 tbsp butter over medium heat.
• Add the chopped onions and sauté until they become translucent and soft—about 3–5 minutes.
• Stir in the garlic, basil, and nutmeg. Let it all mingle for 30 seconds until fragrant.
• Slowly pour in the heavy cream, whisking as you go. Bring to a gentle simmer.
• Simmer for about 5 minutes, allowing the sauce to reduce and thicken.
• Stir in 1/2 cup Parmesan cheese and Monterey Jack cheese.
• Whisk until smooth and creamy. Season with salt and pepper to taste.

Step 4: Assemble the Gratin

• Place the cooked shrimp evenly in your greased baking dish.
• Pour the creamy cheese sauce over the shrimp, ensuring everything is well coated.

Step 5: Add the Crust

• In a small bowl, mix together the remaining 1/4 cup Parmesan cheese and crushed pork rind crumbs.
• Sprinkle this mixture generously over the top.

Step 6: Bake

• Slide your dish into the oven and bake for 25 minutes.
• The top should be golden and bubbling.

Step 7: Cool and Serve

• Let the gratin rest for 5 minutes after baking.
• This helps the sauce thicken up a bit and keeps mouths from burning!

🧊 Storage Tips – How to Store & How Long It Lasts
