- 2 cups (480 ml) heavy cream
- ½ cup (115 g) unsalted butter
- 4 oz (115 g) cream cheese, softened
- 1 ½ cups (150 g) shredded mozzarella cheese
- 1 cup (100 g) grated Parmesan cheese

- 1 tsp Cajun or seafood seasoning
- ½ tsp salt

Equipments
- Large pot for boiling pasta
- Colander
- Medium saucepan
- Wooden spoon or whisk
- 9×13 inch baking dish
- Measuring cups and spoons
- Knife and cutting board
- Aluminum foil
Instructions
- Preheat your oven to 350°F (175°C) so it’s ready once the pasta mixture is assembled.
- Bring a large pot of salted water to a boil and cook the penne pasta according to package instructions until just al dente.
- Drain the pasta thoroughly and rinse lightly with cool water to stop further cooking.
- Set the pasta aside and allow excess moisture to drain completely to avoid a watery bake.
- In a medium saucepan over medium heat, add butter and allow it to melt slowly.
- Pour in the heavy cream and stir continuously to combine with the butter.
- Add the cream cheese and stir until fully melted and smooth, creating a rich base.
- Add minced garlic, Cajun seasoning, salt, and black pepper, stirring well to distribute flavors evenly.
- Reduce heat to low and whisk in grated Parmesan cheese until the sauce thickens slightly.
- Let the sauce simmer gently for 2–3 minutes to deepen flavor without burning.
- Add the cooked pasta into a large mixing bowl and pour the creamy sauce over it.
- Toss gently until all pasta is evenly coated with the sauce.
- Add chopped crab meat and fold it into the pasta mixture carefully to keep pieces intact.
- Lightly grease a 9×13 inch baking dish and spread half of the pasta mixture evenly.
- Sprinkle half of the mozzarella cheese over the first layer.
- Add the remaining pasta mixture on top and spread evenly.
- Finish with the remaining mozzarella and additional Parmesan cheese for a golden crust.
- Cover loosely with aluminum foil to prevent the cheese from over-browning too quickly.
- Bake in the preheated oven for 20 minutes.
- Remove foil and bake for an additional 10 minutes until the top is bubbly and lightly golden.
- Remove from oven and allow the casserole to rest for 5–10 minutes before serving.
- Garnish with chopped parsley and a light sprinkle of paprika for color and flavor.
