# What You'll Need:

→ Seafood

01 - 1 pound raw medium shrimp, peeled and deveined

→ Pasta

02 - 12 ounces penne or rotini pasta

→ Alfredo Sauce

03 - 2 tablespoons unsalted butter
04 - 3 cloves garlic, minced
05 - 2 cups heavy cream
06 - 1 cup freshly grated Parmesan cheese
07 - 1/2 cup whole milk
08 - 1/2 teaspoon salt
09 - 1/4 teaspoon black pepper
10 - 1/4 teaspoon ground nutmeg

→ Vegetables

11 - 1 cup frozen peas, thawed
12 - 1/2 cup chopped sun-dried tomatoes

→ Cheese Topping

13 - 1 cup shredded mozzarella cheese
14 - 1/4 cup grated Parmesan cheese

→ Garnish

15 - 2 tablespoons chopped fresh parsley (optional)

# How to Make It:

01 - Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish.
02 - Boil pasta in a large pot of generously salted water until it reaches the al dente stage. Drain thoroughly and set aside.
03 - In a large skillet over medium heat, melt the butter. Add the minced garlic and sauté until fragrant, approximately 1 minute.
04 - Incorporate the heavy cream and whole milk into the skillet. Bring the mixture to a gentle simmer, then reduce the heat to low. Gradually whisk in the grated Parmesan cheese, salt, black pepper, and ground nutmeg. Continue to cook, whisking occasionally, until the sauce is smooth and has slightly thickened, about 3 to 4 minutes.
05 - Add the prepared shrimp to the Alfredo sauce. Cook just until the shrimp turn pink and are opaque, approximately 2 to 3 minutes. Remove the skillet from the heat.
06 - In a large mixing bowl, combine the cooked pasta, the Alfredo shrimp mixture, thawed peas, and chopped sun-dried tomatoes. Toss gently to ensure all components are evenly coated.
07 - Transfer the combined mixture into the prepared baking dish, spreading it evenly. Top with the shredded mozzarella cheese and the additional grated Parmesan cheese.
08 - Bake in the preheated oven for 20 to 25 minutes, or until the cheese topping is fully melted and golden brown and bubbly.
09 - Allow the casserole to rest for 5 minutes before serving. If desired, garnish with fresh chopped parsley.

# Additional Tips::

01 -
  • Uses everyday ingredients found in most kitchens
  • One-pan baking means less clean-up and easy serving
  • Ready in under an hour but feels special and indulgent
  • Customizable with your favorite veggies and substitutes
02 -
  • Packed with protein from shrimp and cheese
  • Crowd pleasing main that pairs with many simple sides
  • Leftovers reheat beautifully for lunch the next day
03 -
  • Always cook the pasta just until barely tender so it does not overcook
  • Shred your own mozzarella and Parmesan for smoother melting and full flavor
  • If you want an extra golden crust broil the casserole for one to two minutes at the end watching it closely
