Step‑by‑Step Instructions for Creamy Seafood Stuffed Shells
Step 1: Preheat and Prepare Pasta
Begin by preheating your oven to 375°F (190°C). In a large pot of salted boiling water, cook your jumbo pasta shells until they are al dente, which typically takes about 9-11 minutes. Once done, drain the shells and set them aside, ensuring they don’t stick together as you prepare the filling.
Step 2: Sauté Aromatics
In a spacious skillet over medium heat, add a drizzle of olive oil and sauté the chopped onion and minced garlic for about 3-4 minutes until they turn translucent and fragrant. The warm aroma should fill your kitchen, signaling that it’s time to add the next ingredient into your Creamy Seafood Stuffed Shells.
Step 3: Add Spinach
Stir in the fresh spinach and allow it to wilt for approximately 2 minutes. Once wilted, remove the skillet from the heat and let the mixture cool slightly. This step is essential for combining the flavors seamlessly in your stuffing, ensuring each cream-filled shell bursts with deliciousness.
Step 4: Make the Filling
In a large mixing bowl, combine ricotta cheese, cream cheese, cooked shrimp, crab meat, half of the mozzarella, salt, pepper, and optional red pepper flakes. Once the spinach mixture has cooled, fold it in gently until all the ingredients are well incorporated. This rich filling is the heart of your Creamy Seafood Stuffed Shells!
Step 5: Prepare Baking Dish
Spread half of the marinara sauce evenly across the bottom of a 9×13 baking dish. This layer of sauce not only adds flavor but also ensures the pasta shells bake perfectly without drying out. Get ready to fill each shell with the delicious seafood mixture you’ve just prepared!
Step 6: Stuff and Arrange Shells
Carefully stuff each cooked jumbo pasta shell with the seafood filling, making sure they are generously loaded for maximum flavor. Arrange the stuffed shells in the prepared baking dish, side by side. Take a moment to marvel at the assembly—you’re well on your way to enjoying your Creamy Seafood Stuffed Shells!
Step 7: Add Sauce and Cheese
Pour the remaining marinara sauce over the stuffed shells, making sure they’re covered but not drowning. Sprinkle the rest of the mozzarella and grated Parmesan cheese on top for a delightful cheesy crust. The combination of sauce and cheese will create a heavenly bake that sings Italian comfort!
Step 8: Bake to Perfection
Cover your baking dish with foil and place it in the preheated oven. Bake for 25 minutes, then remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and golden brown. The sight of melted cheese and bubbling sauce will surely whet your appetite for these Creamy Seafood Stuffed Shells.
Step 9: Cool and Serve
Once baked, remove the dish from the oven and allow it to cool slightly before serving. This brief wait will help everything set beautifully. As you dish out this decadent meal, the satisfying aroma will tempt everyone to gather around the dinner table!
