Step-by-Step Instructions

Step 1: Cook the Pasta

Cook pasta according to package instructions until al dente. Drain and set aside.

Tip: Slightly undercooking pasta helps it hold up during baking.

Step 2: Sauté Seafood and Aromatics

In a large skillet, heat olive oil over medium heat. Add onion and garlic, cooking for 2–3 minutes until fragrant.

Add seafood and cook for 3–4 minutes, just until opaque. Remove from heat.

Step 3: Make the Creamy Sauce

In the same skillet, add flour and stir for 30 seconds to form a roux. Gradually whisk in milk, stirring until smooth and slightly thickened.

Add parmesan cheese, Dijon mustard, paprika, thyme, salt, and pepper. Stir until creamy and smooth.

Tip: Using flour and milk creates a naturally creamy sauce without heavy cream.

Step 4: Combine Pasta, Seafood, and Sauce

Add cooked pasta and seafood to the sauce, mixing gently until evenly coated.

If using spinach or tomatoes, fold them in at this stage.

Step 5: Assemble the Gratin

Transfer the pasta mixture into a greased 9×13-inch baking dish.

In a small bowl, mix panko breadcrumbs, parmesan, olive oil, and parsley. Sprinkle evenly over the top.

Step 6: Bake

Preheat oven to 375°F (190°C). Bake uncovered for 20–25 minutes, until the top is golden brown and crispy.

Allow to cool slightly before serving.

Light white wine like Sauvignon Blanc or Chardonnay

It’s also perfect for meal prep, as leftovers reheat well in the oven or microwave.

Common Mistakes to Avoid

Overcooking Seafood
Seafood cooks quickly. Overcooking leads to rubbery texture.

Skipping the Roux
Flour in the sauce helps thicken it and gives creaminess without heavy cream.

Using Pre-Cooked Pasta
Freshly cooked pasta absorbs the sauce better than leftovers.

Topping Too Early
Add panko topping just before baking to ensure it stays crispy.

Storing Tips for the Recipe

Refrigeration
Store leftovers in an airtight container for up to 3 days.

Freezing
Freeze without the panko topping for up to 1 month.

Reheating
Reheat in the oven at 350°F (175°C) for 10–15 minutes. Add a splash of milk if needed to restore creaminess.

Meal Prep Tip
Prepare the sauce and pasta ahead of time; assemble and bake when ready to serve.
