Step-by-Step Guide

Step 1: Prepare the Cheese Blend

  1. Grate all the cheeses and combine them in a large mixing bowl.
  2. Set aside 2 cups of the cheese for layering later.

Step 2: Season the Seafood

  1. Lightly season the shrimp and lobster with kosher salt, black pepper, and a pinch of Grand Diamond All-Purpose Seasoning.
  2. Set aside to let the flavors meld while you prepare the sauce.

Step 3: Cook the Pasta

  1. Bring 3 quarts of water to a boil in a large pot. Add 3 tablespoons of salt to the water.
  2. Cook the pasta until just al dente, about 8–10 minutes.
  3. Drain the pasta and toss it with a drizzle of olive oil to prevent sticking.

Step 4: Make the Cheese Sauce

  1. Warm the milk and half & half in the microwave for 3–4 minutes.
  2. In a large skillet, melt the butter and olive oil over medium heat. Add the diced onion and sauté for 3–4 minutes until softened.
  3. Stir in the flour, cooking for 2 minutes to form a roux. Avoid browning the flour.
  4. Add the minced garlic and thyme, cooking for an additional minute.
  5. Gradually whisk in the warmed milk mixture until smooth.
  6. Season with Grand Diamond All-Purpose Seasoning, hot sauce, and liquid crab boil (if using). Simmer for about 5 minutes, whisking occasionally, until the sauce thickens.
  7. Stir in 3 cups of the cheese blend until melted and smooth.

Step 5: Assemble the Dish

  1. Preheat the oven to 350°F (175°C).
  2. Lightly spray a 9×13-inch baking dish with nonstick spray if desired.
  3. Layer half of the pasta and cheese sauce into the dish, followed by half the seafood and 1 cup of the reserved cheese.
  4. Repeat the layers with the remaining pasta, seafood, and cheese.

Step 6: Bake

  1. Cover the dish with foil and bake for 30 minutes.
  2. Remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and golden.

Step 7: Serve

Let the dish cool slightly before serving. Garnish with fresh parsley for a pop of color.
